On the afternoon of October 28, the 44 dams of the Wuzhi County Driving Department Control and Guidance Project, the water of the Yellow River has dropped to its daily flow, from the waves to calm.

On October 27, the Yellow Committee terminated the Level IV emergency response for flood and drought disaster prevention in the middle and lower reaches of the Yellow River. The yellow river autumn flood defense, which has touched the hearts of countless people for more than a month, has achieved a major stage victory.

Affected by the large-scale continuous heavy rainfall, on September 19, the Yellow Committee launched a level IV emergency response for flood and drought disaster prevention in the middle and lower reaches of the Yellow River. Since September 27, the Yellow River has experienced three consecutive numbered floods, the water level of xiaolangdi reservoir has repeatedly reached a record high, and the flow of the Garden Hydrological Station has been controlled at about 4800 cubic meters per second for more than 20 consecutive days... The Yellow River faces severe autumn floods.

This year's autumn floods in the lower reaches of the Yellow River are numerous, the process is long, and the magnitude is rare in history. The Yellow River is dangerous in Henan, and the southern section of the Yellow River is the top priority of flood control in the lower reaches of the Yellow River. In the past month or so, on the southern section of the 711-kilometer Yellow River embankment, the local party and government organs, emergency response, fire fighting, electric power and other departments have coordinated operations, and the professional forces of river affairs and local mass defense personnel have jointly inspected, and the whole province has built an iron wall to guard the Anlan of the Yellow River.

In mid-October, When inspecting and guiding the autumn flood defense work in the lower reaches of the Yellow River, Li Guoying, minister of water resources, pointed out that the party committees, governments, and relevant departments at all levels along the Yellow River have made all-out efforts to deal with it, and the responsibility system for flood prevention administrative heads has been effective in name only, and the expansion of defense forces from professional units to mass prevention and mass governance has been realized, the refinement of defense tasks from the overall requirements to the implementation of responsibilities, the transformation of defensive measures from passive rescue to active front-loading, and the comprehensive extension of defensive targets from dangerous sections to the whole line.

In this autumn flood "big test", Cui Feng, director of the Second River Affairs Bureau of the Yellow River in Wuzhi, has a vivid memory. "Between the 42-45 dams of the driving department control and guidance project, because the river is close to the dam, the water flow is easy to cause the project to be dangerous for a long time, according to the flood situation and river potential analysis, we timely strengthened these 4 dams 27 times, with 5768 cubic meters of stone." Cui Fengzhou said that because of the advance judgment and the prevention of problems before they occur, there has not been a single dangerous situation in the jurisdiction.

On the afternoon of October 4, Hu Yunying, director of the Yellow River Affairs Bureau of Lankao, inspected the 18 revetment of the Jiahe Beach Moat Project and found that the river in this section of the river suddenly rose, and the revetment was an earthen dam foundation, and once the water flow washed out for too long, the project would have a greater danger.

"Dispose of it immediately, excavators and loaders will enter the site immediately, throw lead wire stone cages, willow stone pillows and roots, scatter stones to protect the slope, and start the lighting equipment." Hu Yunying issued one after another rushing orders. The excavator roared to grasp the stones and release the stones, the loader drove the cage into the river with full horsepower, and the 30 rescue team members completed the advance protection of the 18 revetments after 8 hours of intense busyness to ensure the safety of the project.

For more than a month, in the Garden Mouth section of the Yellow River, Sun Guangwei, section chief of the engineering management section of the Huijin River Bureau, and his colleagues have always stuck to the front line, exploring the roots and measuring the water level day and night. Sun Guangwei showed reporters the inspection and observation record sheet of these days, which recorded in detail the situation of the revetment project by the river, whether there was water damage, and whether there were any root stones lost.

Government leadership, emergency overall planning, river support, departmental coordination, group prevention and group control, the province's government departments at all levels to coordinate the integration of water conservancy and river affairs departments and group defense team members, 24 hours of uninterrupted inspection of the embankment to check the danger, the dangerous situation early grasp small, eliminate the hidden danger in the bud, to achieve the beach area does not flood the beach, the project does not run the dam, the personnel do not die.

In Lankao, buses for front-line rangers to rest have become a beautiful sight on the Yellow River embankment. During the eleventh holiday, the wind and rain caused the temperature on the banks of the Yellow River to plummet, and the local government urgently coordinated with the local bus company, 16 buses drove to the levee, according to the location of the dangerous section, the bus can not only move back and forth, but also serve as lighting equipment.

"The bus is the equivalent of a movable board room, warmer than a tent and allowing more people to rest temporarily." Jiao Kun, deputy director of the Yellow River Bureau in Lankao, said. In the Lankao section of the Yellow River, which is 25 kilometers long, a special patrol team of 528 people patrolled 24 hours a day to ensure that there was no danger in this autumn flood.

Provincial defense refers to the requirement that in the inspection and defense of river projects, professional personnel and group defense personnel should be equipped according to 1:3. During the interview, the reporter found that in some places, the ratio even reached 1:5. The group defense force coordinated with professionals, and through seeing, touching, ear listening, and foot probing, "took the pulse" of the water level and flow rate changes, and played a key role in patrolling the embankment and checking risks.

In late October, the Yellow River entered a receding period. According to years of experience in flood control, the Yellow River retreat period is the period with the highest probability of flood control projects. On October 25, at the East Dam head control and guidance project, due to the high water level soaking for many consecutive days, the foundation was in a state of complete water saturation, and as the water pressure continued to drop, a crack about 200 meters long appeared in the project. After the group defense personnel who were patrolling the embankment to check the danger found the problem, they immediately reported it, and the local emergency used a long-arm excavator to throw stone into the crack, filling it and pressing it tightly, avoiding the occurrence of dangerous situations.

On the day of the reporter's interview in Wuzhi, Li Renba, a 66-year-old villager in the driving department of Dafeng Town, wore an orange flood control suit and still insisted on carrying out daily patrols of the driving department control and guidance project under his jurisdiction. ”

"Although the emergency response has been lifted, we are still insisting on 24-hour inspections, and the water has not completely receded, so we cannot take it lightly." The relevant person in charge of the Yellow River Bureau in Henan said.
