◎ Rare autumn flood, so meet the battle
"Carrying sand and gravel, often soaking in water, 'fingerprints are worn away'" "Embroidery efforts, disposal of floods on each side, comprehensive adoption of 'stopping, storage, delivery, discharge' measures..." More than 2,500 Yellow River system staff and more than 15,000 group defense team members at all levels in our province have invested every day to carry out dam inspection and beach area defense, and carry out 24-hour uninterrupted inspections in 66 dangerous points. At the same time, we will actively coordinate and communicate with the Yellow Committee, the Maritime Commission and other river basin agencies, and request to strengthen project scheduling, give full play to the role of project peak shaving and peak shifting, and minimize the flood control pressure in our province...
◎ When the flood hit, what happened to the people in the beach area?
"Our village is a beach area village, only more than 200 meters away from the closest place to the Yellow River, in the past the flood will worry about the collapse of the village platform, now the village platform is reinforced to 5.5 meters high, the village platform soil slope is lined with six-sided cement blocks, and special vegetation is planted between the gaps to prevent erosion" "Although the Yellow River is large this time, there is still a bottom in the heart"...
◎The villagers who were transferred, how well did they live?
At the resettlement site, li Zaifeng, a relocated villager, had just finished eating the hot meal that the grid staff had brought for him. He said: "This time when the water came, the village took me here to live, bought me toiletries, and brought me food every day. ”
Fight for a rainy autumn
- Defense against rare autumn floods on the front lines
□ Reporters Zhao Feng and Wang Hongjun
On the Jinshan Dam in Dongping Lake, a duty watch hung in the tent of the flood control headquarters, which had been queued until October 21. Since the autumn flood on September 20, the flood control command has been holding out on the levee for more than 20 days.
On October 6, the Provincial Flood Control and Drought Control Headquarters issued an emergency notice that the Xiaolangdi Reservoir will continue to discharge a large flow, and the flood process of about 5,000 cubic meters per second in the Yellow River channel in Shandong will last for about 15 days.
Round after round of autumn rain, the main tributaries of the Yellow River generally swelled, the maximum flow of the main stream of Gaocun Station in our province was 4990 cubic meters per second, the maximum flow of Aishan Station was 5330 cubic meters per second, the maximum flow of Lijin Station was 5110 cubic meters per second, and the flow of the river section in our province was maintained at the order of 5000 cubic meters per second; the maximum water level of Dongping Lake was 42.47 meters, 0.75 meters above the alert water level, and the flood control situation was grim. The reporter squatted along the Yellow River and Dongping Lake to record the bits and pieces of the flood prevention line.
Carrying sand and gravel, often soaking in water, "fingerprints are worn out"
14 dangerous workers, 4 control guides, 4 yellow culvert gates, 110045 step.
From October 2 to 6, the rescue expert group led by Zhu Yunfeng, chief engineer of the Yellow River Bureau of Dezhou, carried out a full-coverage inspection of the Yellow River flood control project in Dezhou on foot, creating a record of 110,000 steps per person walking in 5 days.
Orange is a moving color in the current war and autumn flood. Flood control personnel in orange overalls defend against autumn floods with responsibility.
"Ding Ding Ding", at 10:00 a.m. on October 6, the alarm clock of Zuo Aihua, a front-line inspector of the Xidaokou Dangerous Workers in the Qihe section of the Yellow River, sounded, reminding himself to take antihypertensive drugs.
"I'm older and my blood pressure is high." Although Zuo Aihua, a cadre of the Yellow River Bureau in Dezhou, is about to retire, this time she and more than 20 female colleagues took the initiative to invite Miao to the front line. Liu Huihua, head of the party and mass section of the Qihe Yellow River Affairs Bureau, said that there are more than 30 female comrades in the Qihe County Bureau, and there are also more than 20 people who have sunk to the front line.
Because the weather became colder, the lesbian front-line duty time was adjusted to 6 a.m. to 2 p.m. For Hu Fangfang, a sinking officer of the Yellow River Bureau in Texas, she has to get up at 4:30 a.m. every day. Although she couldn't bear to watch the child cry, she felt that this was the responsibility of the Yellow River people.
On the morning of October 6, the cold rain was dense, and the wind on the bank of the Yellow River was strong, and after nearly an hour, an inspection was over. "Although I was wearing a raincoat, the rain flowed all the way down the raincoat into the rain boots, and you could hear the sound of the water shaking as soon as you walked." After the inspection, Hu Fangfang came to the temporary movable board room to temporarily rest and shelter from the wind and rain for a while.
"Although female comrades are not as 'anti-manufacturing' as male comrades, we also have the advantage of carefulness." Ge Aichun, a front-line guard on duty at the sinking of the Yellow River Bureau in Texas, said that it is particularly important to be careful in patrolling the river and checking risks. Every time she inspects a place, she always has to find a good contrast marker, take a photo with her mobile phone, and compare it every day to judge the water conditions. She pointed to a photo on her mobile phone and told reporters that here we chose a tall grass next to the beach, which we call "grass strong", which has not been flooded two days ago, and now it is half gone.
"In addition to the responsibility and mission of the work, the support of our families is also the driving force for us to persevere. In this sense, flood prevention is not only these people on the front line, but also thousands of families behind them. Hu Fangfang said that her family encouraged her, "Persistence is victory."
On the evening of October 5, the reporter accompanied the front-line duty employees on night patrol of the Yellow River. That night, the Qi River was drizzling, and the temperature had dropped rapidly from nearly 30 °C in the previous days to about 13 °C.
"Dangerous situations are easy to appear at night, and the visible conditions at night are limited, which will have an impact on the timely detection of dangerous situations, and at night, when people are easily tired and tired and slack, there may be cases that cannot be found in time to detect dangerous situations, resulting in the expansion of dangerous situations." Wang Junqing, who was on duty from 10 p.m. to 6 a.m. the next morning, told reporters that the midnight was the most probing and the most testing. Because they have to patrol 24 hours a day, they have to go out every once in a while to patrol.
Wang Junqing was a party member, and he and his colleagues in the management section wrote a petition to take on the hardest work.
"When we arrange the duty period, we pay special attention to giving play to the exemplary and leading role of party members, and arrange conscientious and responsible party members to work at night." Mi Yuzheng, the head of the tofu nest management section, said that there are a large number of party members among the staff and workers in the management section and the organs, and they have set up temporary party branches on the front line.
"In the past few days, carrying sand and gravel and pressing geotextiles, I often soak in the water, and the fingerprints of the index finger of my right hand are worn away." Li Jie, secretary of the party committee of Yinshan Town, Dongping County, now feels very "awkward" when he unlocks it with his fingerprint.
Guo Dong, deputy county magistrate of Dongping County, said: "At present, dongping Lake Jinshan Dam flood control adopts a theater responsibility system, the water surface is divided into 14 defense areas, the back water surface is divided into 5 responsibility sections, 24-hour patrol duty, increase the frequency and density of inspections, strengthen the allocation of professional and technical personnel, and ensure that dangerous situations are found at the first time, reported at the first time, and dealt with in place at the first time." In particular, if the pipe surge cannot be found and disposed of in time, there will be a risk of dam collapse. It can be said that the further back you go, the heavier the responsibility for checking the embankment. ”
It is better to be prepared than useless, and it is not available to be unprepared. On the morning of October 8, next to jinshan dam, Sun Jingfu, a villager in Sunzhuang Village, Daimiao Town, Dongping County, and more than a dozen villagers rushed to pack sandbags.
"Each sandbag is about 50 kilograms, and after it is packed, the villagers drive their own motorized tricycles to the defense areas of various townships (towns) in Jinshanba for backup." Sun Jingfu, who patrols the dam every year for flood control, said that the villagers have been working here for four or five days, and although the situation feels grim, it is now much stronger than in earlier years. "The dam has been widened, and in the past, the flood control was afraid of the waves impacting the embankment, using grass handles, and now using geotextile, there are more 'high-level', and people from various townships (towns) and departments have come, and the flood prevention force is very strong."
"My mother has gallbladder cancer and has just had surgery. Since September 27, when the emergency response to flood and drought disaster prevention in the middle and lower reaches of the Yellow River was upgraded to Level III. Speaking, Gao Jiaquan, the person in charge of the management section of the High Village of the Yellow River in Dongming, choked up a little.
According to statistics, more than 2,500 Yellow River system workers and more than 15,000 group defense team members are invested at all levels in our province every day to carry out dam inspection and beach area defense. In the 66 dangerous points and sections, inspectors have been fixed, the insurance room has been built, equipped with lighting equipment, and the 24-hour uninterrupted inspection is strictly carried out to ensure that the dangerous situation is detected and dealt with early.
"Under the embroidery effort, dispose of each side of the flood"
"Hello, is it the town flood control headquarters?" When we were patrolling the Jinshan Dam, we found more than twenty dams that had depowed, and asked the town to immediately arrange personnel to dispose of them..." At about 3 a.m. on September 25, the staff of the flood control headquarters of Yinshan Town, Dongping County, received an early warning call, and the caller was Yin Fulei, secretary of the party branch of Xuanqiao Village. On the evening of the 24th, according to the local flood control requirements, Yin Fulei braved heavy rain and strong winds to lead a number of villagers to patrol the embankment on the Jinshan Dam to check the safety of the dam.
Yin Fulei, who was using a lithium flashlight to check the dam body, suddenly saw a dam body depowd, followed by a number of dam stones that were knocked down by the wind and waves. Knowing that it was not good, he immediately organized personnel to continue to patrol along the dam body and count the number of slope removals of the dam body. After careful investigation, he found more and more dams depowing, and immediately picked up his mobile phone to warn the town flood control headquarters.
"We reported it step by step at the first time, and the county emergency management bureau responded quickly, dispatched a number of experts to investigate on the spot, and in accordance with the emergency plan, began to mobilize all emergency rescue forces in the county to rush to the aid of Jinshan dam." Li Jie said that after the analysis, this dangerous situation was related to the fact that there were more southeastern and northeasterly winds at that time, and the wind and waves constantly washed away the dam.
Flood is the command. At about 6 o'clock, more than 270 cadres and masses in Yinshan Town and 11 surrounding villages quickly rushed to the dangerous area, and Yin Fulei, who was more than 1 meter and 8 heads, was a veteran and took the lead in jumping into the water. He said, "We wore a protective rope to the water, first filled in the slope with sand and gravel bags, then laid with geotextiles, and then compacted and compacted with sand and gravel bags." ”
At about 11:00 a.m., 33 other villages in Yinshan Town received instructions to urgently transfer sandbags, stone bags and other flood control materials. An hour later, all supplies were in place. At about 2 p.m., all 37 dangerous places were repaired.
Guo Dong said: Since the beginning of the flood season, the county's emergency, water conservancy, meteorology, Dongping Lake Management Bureau, Dongping Lake Management Bureau, Dongping Yellow River Affairs Bureau, and other departments have always paid close attention to changes in rain, water, flood, and work conditions, and promptly issued early warning information.
From 6:30 to 7:00 on October 4, the Bali Bay FloodGate of Dongping Lake opened the third and fifth hole gates, opening the height of 0.4 meters, and from 10:50 to 10:55, the opening height was adjusted to 0.5 meters, and the flow of the lake was measured by the Daicunba Hydrological Station of 29.4 cubic meters per second.
This is the first time that the floodgates in Bali Bay have been discharged after the completion of the flood gate, and the water of Dongping Lake has been discharged south through the downstream channel and finally reached the South Fourth Lake. The gate is located in the secondary lake embankment of Dongping Lake, with a total of 7 gates, a design flow rate of 450 cubic meters per second, and the main function is to increase the discharge road of the old lake of Dongping Lake, and achieve the joint control and application of the new lake and the old lake.
"The discharge of floodwater from the south of the Bali Bay Flood Gate can effectively reduce the water level of Dongping Lake, while reducing the discharge pressure of Dongping Lake and ensuring the safety of flood control in the lower reaches of the Yellow River." Yue Shanping, deputy director of the Dongping Lake Management Bureau, said. According to the real-time water situation, at 9 o'clock on October 8, the water level of Dongping Lake was 42.43 meters, the water flowing out of the Lake out of the Qinghe Gate Gate to the Yellow River was 188 cubic meters per second, and the water from the Lake such as the Jiping Trunk Canal, the Bali Bay Boat Lock, and the Bali Bay Flood Gate was 366.4 cubic meters per second, which is expected to reduce the flood by 426,000 cubic meters per hour. Qu Feng, deputy secretary of the Tai'an Municipal Party Committee and secretary of the Dongping County CPC Committee, said, "Under the embroidery effort, the flood in each side is handled, and the measures of 'stopping, storing, sending and discharging' are comprehensively adopted to finely and accurately dispatch the flood discharge of Dongping Lake in an orderly manner." ”
The relevant person in charge of the Provincial Flood Prevention and Drought Control Headquarters said that the Provincial Flood Prevention And Drought Control Command actively coordinated and communicated with the Yellow Committee, the Maritime Commission and other river basin agencies, and proposed to strengthen project scheduling, timely regulate the discharge flow of control projects such as xiaolangdi reservoir and Yuecheng reservoir, give full play to the role of project peak shaving and peak shifting, and minimize the flood control pressure in our province. Point-to-point continuous tracking and dispatch of the situation of cities in the heavy rainfall area, pay close attention to the flood defense situation of cities and counties along the Zhangwei River and Jindi River, timely organize water conservancy, emergency response and other departments to send a number of supervision working groups to the front line of defense, supervise and guide the flood defense response work, and ensure that all defense work is in place. At the same time, give play to the role of the regional coordination and linkage mechanism of the Yellow River Basin and the Hai River Basin. At present, our province has implemented 5 regional emergency rescue centers and 35 provincial-level professional rescue teams for disasters and accidents, and can go to the front line for emergency rescue at any time.
Although the water is large, the villagers in the beach area who live in new houses have a bottom in their hearts
Guo Yanping, director of the Yaozhuang Village Committee of Xingdong Community in Dongming County, has led the people of the village these days to patrol the Yellow River section twice a day within the responsibility of the village.
"This year's water is relatively large, even if you are accustomed to seeing the yellow river water, such a large flow is rare, you need to turn around often to see if there is a dangerous situation, in order to find out and deal with it in time." Guo Yanping, born in 1965, grew up in Yaozhuang Village in the beach area, the village is only two or three kilometers away from the Yellow River embankment, and the villagers' land is mostly in the beach area. With the Yellow River as a companion, not only enjoy the benefits of the Yellow River, but also live in the "shadow" of the Yellow River.
"In the past, as soon as the Yellow River burst into water, the autumn crops were gone." Guo Yanping said that not only are the crops damaged, but also the yellow riverbed is much higher than the terrain of Yaozhuang Village, and the houses are flooded at the first time, and the people in the beach area have been repeating the cycle of "3 years of saving money, 3 years of cushioning, 3 years of building houses, and 3 years of repayment".
However, looking at the Yellow River this year, Guo Yanping is no longer as nervous as before. During the Spring Festival in 2020, villagers in Yaozhuang Village moved into a new community house on the platform of No. 8 Village in Changxingji Township. This is the first of the 24 villages in Dongming County to meet the conditions for occupancy, and the houses are high and no longer affected by floods.
Among the 17 counties and districts involved in the relocation of beach areas in Shandong, Dongming County has the largest scale and the heaviest task, and is the main battlefield for the relocation and construction of the Yellow River beach area. In May this year, the last batch of 4,843 villagers in the last batch of 12 beach district villages in Dongming County chose houses to households, and all 28 villages in the Yellow River Beach District of Heze were housed to households. Guo Yanping said: "Although the Yellow River is large this time, there is still a bottom in my heart. ”
There is another reason that makes Guo Yanping feel at ease, that is, the yellow riverbed is declining. "In the past, this section of the Yellow River in our village was hanging high, but after so many years of enlarging the water wash, the riverbed was pulled down by two meters."
The "big water" in Guo Yanping's mouth is the Yellow River water diversion and sand diversion carried out continuously by the Yellow River Water Conservancy Committee of the Ministry of Water Resources. Under the conditions of modern technology, the main tributary reservoirs are used to regulate the water and sand process entering the downstream, shape a relatively coordinated water-sand relationship, reduce the siltation of the reservoir channel, and restore and maintain the middle water trough.
On June 19 this year, the water diversion of the Yellow River before the flood began, during which the maximum discharge flow of the Xiaolangdi Reservoir reached 4500 cubic meters per second. "After the official launch of the yellow river water diversion before the flood, the flow of the Yellow River in Dongming increased several times than usual, reaching 4,000 cubic meters per second. For example, the flow rate of the Dongming section is usually 1 gear, and when the water is transferred and the sand is transferred, it can reach 3 gears and 4 gears. Gao Jiaquan said.
As the first stop of the Yellow River into Lulu, the Dongming Yellow River channel is generally north-south flowing, the river is wide and shallow, the mainstream is scattered, chaotic, and swings frequently, it is a wandering river section, which is a weak section of flood control in the lower reaches of the Yellow River, known as "tofu waist". Since 8 o'clock on June 15, the Yellow River Affairs Bureau of Shandong Province has launched a 24-hour flood prevention and shift duty system. Located near Yaozhuang Village, the management section of the Yellow River High Village in Dongming began to be fully staffed, paying close attention to changes in the rain, water and work conditions of the Yellow River, reporting flood control information according to regulations, and rushing to protect them in time once there is a dangerous situation. "Measuring and recording is the height of the water outlet of the beach lip, and the change of water level is understood by measuring the distance and change from the river surface to the horizontal surface. The embankment of the Yellow River is a loam structure, the embankment is washed underneath, it is easy to 'wear a hat', and the close measurement may encounter the danger of the collapse of the beach at any time, so it is necessary to tie it with a safety rope to prevent danger. Yang Jian, a 46-year-old river patrol team leader, is an "old Yellow River" rooted in the flood control line of the Yellow River for more than 20 years, and has a lot of experience. Gao Jiaquan said, "After water diversion and sand transfer, the riverbed in the Gaocun section has dropped by about 2 meters, which can withstand a larger flow than before." ”
According to the official data of the Yellow River Water Conservancy Commission of the Ministry of Water Resources, the pre-flood water and sand diversion of the Yellow River in 2021 is the 20th consecutive year that the Yellow River has implemented water and sand transfer. Through water diversion and sand transfer, the main river trough of the downstream river channel was reduced by an average of 2.6 meters, and the minimum overflow capacity of the main river trough was restored from 1800 cubic meters per second before the flood in 2002 to about 5000 cubic meters per second before the flood in 2021, and the flow capacity of the main river trough was significantly improved.
Similar to Guo Yanping in Dongmingtan District, standing on the platform of the new house, Gao Shulan, a villager in Gaojia Village, Northern Song Town, Lijin County, watched the gushing Yellow River water gushing through the south of the village. Gao Shulan said: "Our village is a beach area village, only more than 200 meters away from the Yellow River, in the past the flood would worry about the collapse of the village platform, now the village platform has been reinforced to 5.5 meters high, the village platform soil slope is lined with six-sided cement blocks, and special vegetation is planted between the gaps to prevent erosion." ”
There are 3 inhabited Yellow River beach areas in Lijin County, and the flood pressure in the beach area is large. Since 2018, Lijin County has implemented the renovation project of the old village platform, in which the 8 beach district villages in the Northern Song Dynasty Town have carried out village platform reinforcement, road hardening, drainage in the village, weak electricity to the ground, concentrated on reinforcing the old village platform, and changing the raw retaining wall into a masonry retaining wall, which improved the flood control capacity of the village platform.
The displaced villagers ate hot meals
- The water level reaches 41.72 meters to 42.72 meters, the defense enters a tense state, and the 24-hour patrol of the embankment begins;
- When the water level reaches 42.72 meters to 43.22 meters, the defense enters a serious state and is ready for relocation;
When the water level reaches above 43.22 meters, the defense enters a dangerous state, and the people in the west of the dam must all evacuate...
This is the content of the Dongping Lake District Distress Transfer Plan.
The first-class lake area of Dongping Lake needs to transfer 27 villages, with a registered population of 29,887 people in 9,489 households. After accurate mapping, 12,702 people from 4,143 households need to be transferred, including 415 people who are old, weak, sick and disabled.
At about 9 o'clock on October 8, the water level of Dongping Lake was 42.42 meters, and the super alert water level was 70 centimeters, but it had not yet entered a "serious state". However, a few days ago, Sun Jingfu had already received a notice to prepare for evacuation. "I was peeling corn at home when someone came to inform me that if the water level rose, I would have to move to a nearby community resettlement site in time." He said, "Let me put corn on the roof and put my valuable belongings on a high place, and someone will come and shout (evacuate)." ”
In Yinshan Town, located in the north of Jinshanba, there are 13 villages where the masses need to be relocated, of which 6 villages can be resettled locally and 7 villages need to be relocated. Li Jie said, "According to the mapping, these 7 villages involve more than 3,000 people, and now the basic living security and materials are ready." ”
Each of the 27 villages in Dongping that needs to be transferred has formulated a specific implementation plan, including the number of people transferred, methods, routes, and vehicle arrangements; there is a special class guarantee (each special class is composed of a county-level cadre, a county-level department, and town and village cadres), and all of them have been sunk to the village; each village has fixed a centralized resettlement site, and a total of 18 resettlement sites have been set up. In particular, for those special groups such as the old, weak, sick and disabled, widows, widows and loneliness, it is necessary to be responsible for "one-on-one" special personnel, and transfer them to the homes of their relatives and children in advance, which can not only ensure their life safety, but also ensure that their lives are taken care of.
At 6 p.m. on October 9, at the office of the former village committee of Sancha Village in Northern Song Town, Lijin County, villager Li Zaifeng had just finished eating the hot meal brought to him by the grid staff. He said: "My house is under the village platform, and this time when the water came, the village took me here to live, bought me toiletries, and brought me food every day." ”
Sancha Village is located in the Yellow River Beach area, as the flood situation continues, for the sake of safety, Lijin County organization organ cadres, members of the village "two committees" and other door-to-door inspections, the villagers living under the stage through centralized resettlement and other ways to ensure the safety of the masses. At present, Lijin County has moved 127 households and 269 people from 127 households in the Yellow River Beach District of the Northern Song Dynasty to safe residences one by one. At the same time, special personnel were organized to conduct house-by-house inspections of nursing houses and breeding houses in the beach area to ensure that the houses were uninhabited.
At present, all levels in the province have done a solid job in the transfer and resettlement of personnel, as of now a total of 5328 people have been transferred and resettled, and the remaining townships and villages that have not yet met the conditions for transfer have also implemented transfer plans and measures to ensure the safe evacuation of the first time when they should be transferred.
At the same time, the provincial level of our province has implemented 35 professional rescue teams and material equipment, pre-positioned fire rescue forces in Tai'an, Dezhou, Liaocheng and other cities in advance, and 43,376 rescue forces of various types in relevant cities and counties, assembled and standby...
