The city-wide operation to meet the "quick freezing" to ensure that the public can survive the cold wave safely

The cold wave struck, and strong cold air arrived in Shanghai yesterday. As of press time, the forecast indicates that light snow or sleet may occur in some parts of the city. Following the "double blue" warning of cold wave and gale at 6 o'clock yesterday morning, the temperature has dropped gradually in the intermittent rainfall, and there will be freezing or severe freezing in local areas this weekend. In the face of "freezing truth", all parties in the city have compacted their responsibilities, refined preventive measures, made every effort to deal with emergencies, and on the basis of guarding the bottom line of safety, they also care about the front-line workers who still stick to their posts and ensure the operation of the city under the "quick-freezing mode", so that the people can safely survive the cold wave.

The perimeter of the vegetable field is non-slip, and half of the 5 kg salt bags are empty

In the evening, the rain finally stopped, and Zhang Yue, a young sanitation worker from the Linfen Qingdao team of Jing'an Urban Development Group's Jinghuan Operation Department 3, took the team employees to the streets. Wielding a broom vigorously, he swept the stagnant water and sediment at the entrance of the vegetable market on Anye Road to both sides of the road. After cleaning up all the stagnant water on the road, Zhang Yue circled around the vegetable market and immediately "locked" several points that were prone to freezing. He carried a bag of salt containing 5 catties of salt in one hand, grabbed a full handful with the other hand, and threw more than ten back and forth to the ground. Walking around the wet market, the salt bags were half empty.

"There may be freezing in the early hours of the next morning, so be prepared in advance, and if there is sleet, the salt will have to be added. "In response to the cold wave, the third department of Jinghuan Operation set up a 10-person emergency team. At the workstation, the team members prepared a ton of salt and some snow shoveling equipment, and the team also distributed ginger tea and warm babies to the employees.

In fact, at 5 o'clock yesterday morning, the team was busy. The sudden drop in temperature caused a sharp increase in leaf fall on many small roads such as Yangquan Road and Wenxi Road. Seeing this, Zhang Yue deployed a three-wheeled electric cleaning vehicle on each of these roads. The swept garbage is directly thrown into the cleaning truck and collected and transported in time.

After a round of rain, Zhang Yue and others re-cleaned the road surface, and also took a large rag to wipe the roadside garbage bin repeatedly. According to the plan, the emergency response team will also patrol the streets at fixed points, find water accumulation points, ice places, etc., and call for reinforcements in time and solve them in time.

The water pipes in the old house keep warm, and also remind the elderly of cold prevention skills

"There's a wire trough here, and the bandage is stuck!" In the nearly 100-year-old Ruijin apartment, Gu Xingbing, an emergency maintenance master of Yongshan Company, snorted on the scaffolding more than 2 meters high. "Do you want me to come up and help?" Wu Xiafang, the maintenance master below, heard the sound and stabilized the scaffolding he was holding steadily. Eventually, the 2-centimeter-thick elastic wrap material clings to the wire duct and passes through the extremely narrow gap. The old house was exposed to the outdoor pipes, and the bandaging was successful. "It looks simple, but it's a test of effort. Gu Xingbing doesn't like to wear gloves when working, even if his hands are cut open from time to time, "the gloves are less touched, and the efficiency is low."

The temperature plummeted, and the staff of Huangpu District Yongshan Construction and Maintenance Company made a comprehensive inspection of the old community under its jurisdiction, and took protective measures against exposed water pipes and fire pipes with warm materials. Taking Ruijin Apartment as an example, nearly half of the residents living in it are over 60 years old, and after the water pipes are "all covered", the package of fire pipes is also on the agenda. Each layer of fire pipes is 3 meters long, a total of 6 floors, and each section needs to be accurately measured in length, and the appropriate size insulation pipe is quickly cut, tightly wrapped around the pipe and tied with cable ties.

An old man heard the movement outside and poked his head out to ask. Chen Gang, manager of the emergency rescue team of Yongshan Company, reminded the elderly to do a good job of self-protection and cold protection: "Once the faucet is frozen, you can wrap the faucet with a hot towel, pour warm water, and then unscrew it after thawing." ”

According to reports, since October, Yongshan Company has launched a special plan for anti-freezing and warmth. Up to now, a total of more than 490 personnel have been dispatched, more than 2,000 places in the jurisdiction have been inspected, 4,150 meters of water pipes have been newly bandaged, and 5,430 meters of water pipes have been overhauled. At the same time, all kinds of anti-freezing emergency supplies are prepared, including more than 3,500 meters of water pipe insulation pipe reserves, more than 1,100 meters of PPR water pipes, and 500 pieces of water meter glass.

Intelligent traffic management research and judgment, and the bridge that is prone to ice is classified as a risk point

Yesterday afternoon, with a cold wind and drizzle, the vehicles on Fengpu Avenue slowed down and drove cautiously across the river. Through the patrol on the screen, this scene, along with several other important points in the jurisdiction, was reflected in the eyes of Qian Ang, deputy director of the Intelligent Traffic Management Center of the Fengxian Branch of the Municipal Public Security Bureau, and his colleagues.

"The system has just completed the functional upgrade and encountered this cold wave," Qian Ang introduced, the smart traffic management system collects historical police information, easy congestion points, 12345 citizen service hotline and other data, and uses big data analysis and collision to determine the points that are susceptible to the cold wave.

In Qian Ang's memories of the cold wave, there is always the figure of Fengpu Avenue. In a certain year's cold wave, since the morning rush hour, 110 police continued to rise, and a number of traffic accidents occurred one after another, "most of them were due to the icing on the bridge deck caused by side slipping, and the brakes were not enough to cause collisions, although there were no casualties, but the vehicles were damaged, and the police were also exhausted." ”

With the establishment of the traffic police department's traffic research and judgment room, the focus of work has shifted from post-disposal to pre-research and judgment, "more emphasis is placed on prevention before it happens, and accidents are reduced from the source." Combined with big data analysis and the foot strength and experience of the front-line traffic police, the Fengxian traffic police department will focus on the viaduct deck, the lower overpass, the bridge hole, the uphill and downhill sections, as well as the easily ignored car wash, vegetable market and other areas prone to water accumulation, accurate police patrols, judge the traffic flow, push the risk intelligence clues to the front line, combined with the weather forecast, timely start the relevant plan, all staff on duty, prepare materials, and sprinkle salt and de-ice before social vehicles on the road.

Care for the elderly living alone, and provide door-to-door services in a "group".

At about 10 o'clock yesterday morning, Gu Jinhong, a 75-year-old elderly man living alone in Jiangjiaqiao Community, Ouyang Road Street, Hongkou District, received a call from Wang Na, secretary of the general party branch of the residential area. Hearing that the old man's house had newly installed a floor heating system, and the old man's back pain caused by cooling caused him to suffer again, Wang Na took the property maintenance worker and the elderly housekeeper to "form a group" to provide door-to-door service.

"Let's check the water and electricity in our home to eliminate potential safety hazards. The maintenance worker said that because the kitchen is also laid with floor heating, once the water leaks, it is easy to cause electric shock accidents. Walking into the kitchen, he squatted down and carefully touched the hose and triangle valve under the bucket to make sure that there was no damage and that the connection was tight, and then shone the pressure pump with a flashlight to confirm that it was working properly. He also takes care of the elderly, and if he finds a water leak, he will notify the property immediately.

The elderly housekeeper takes the initiative to help the elderly dry their clothes. Wang Na reminded the elderly not to go out these days, and to pay attention to safety in household fire, electricity and gas. Wang Na said that after receiving the cold wave prevention tips, the relevant precautions were released in the residential group as soon as possible. Considering the high degree of aging in the community, after understanding the situation through the care telephone, we carried out on-site visits to some elderly people living alone and pure elderly families with special circumstances. Adopt the "group" door-to-door approach to bring property, pension housekeepers and other services into the door.

Warm takeaway guys, gloves and scarves all come in handy

At the entrance of Shangjingyuan Community, Xinjiangwancheng Street, Yangpu District, the "Little Brother Station" spontaneously set up by residents is full of love. It is said to be a "post station", but it is actually several tables with drawers. On the table is an incubator, inside is warm mineral water, and in the drawer are cotton gloves and scarves for the little brother. "The little brother can reach out and get what he needs, and he doesn't have to get out of the car to get it again, saving time," Yu Xiaolin, secretary of the party branch of Shangjingyuan, explained, riding is easy to have cold hands, and the more than a dozen pairs of cotton gloves prepared that day were collected by the little brothers one by one, "It seems to have come in handy." ”

This "Little Brother Station" began in the extreme climate of midsummer, and the high temperature of 40°C made residents aware of the hard work of the takeaway brother. Residents spontaneously prepared some outdoor work necessities for the little brothers who often go in and out of the community, and later expanded from the earliest table to the current "post station" and moved to two entrances and exits of the community in order to benefit more outdoor workers. The items in the "Little Brother Station" were donated by residents and caring enterprises in the nearby Bay Valley Science and Technology Park, "and the ingenious aunts in the community spontaneously knitted scarves to send warmth to the little brother." ”

Guarding bus trips and checking vehicle antifreeze with a freezing point meter

In the Guojiang Road parking lot of the No. 1 bus company, Jin Lu, a repairman, is using an ice point meter to check the antifreeze of the bus. He opened the rear cover of the vehicle, took out a little antifreeze, dripped it on the freezing point meter, and the data was quickly displayed on the instrument.

"As the vehicle is moving, the antifreeze will gradually decrease or the freezing point will not meet the target over time. Jin Lu introduced that the freezing point of antifreeze can effectively prevent the vehicle drive motor from freezing, avoid vehicle failures and breakdowns during operation, and carry out relevant inspections to protect travel safety.

Tyre checks are also essential in winter. The road surface is relatively slippery, and the tire pressure directly affects driving safety. Tire pressure that is too high or too low can cause the vehicle to lose control and become dangerous. The repairman will test the tire pressure of the commercial vehicle in advance, and if it is found that it does not meet the standard, it will be adjusted in time to prevent potential safety hazards.

Sun Hua, deputy director of the repair workshop, led the repairmen to carefully inspect: "There is another link that is easy to be overlooked, that is, the gas tank. If the water vapor in the gas tank is not cleaned in time, it is easy to freeze and block the gas path in low temperature weather, resulting in the door cannot be opened normally. Therefore, the repair worker drains the vehicle's gas tank to ensure that the bus is functioning properly.

In the howling cold wind, put on "warm clothes" for vegetables in advance

In the early morning, the morning sun shines on the ridges of the countryside, and in the white plastic greenhouses, the green vegetables are full of vitality, and Yan Zhonghua, the person in charge of Luoxin Horticulture, carefully inspects. As one of the three major vegetable cooperatives in Luojing Town, Baoshan District, there are 128 vegetable greenhouses growing common winter vegetables such as spinach and greens.

In response to the cold wave this year, Yan Zhonghua recruited more than ten temporary workers in advance to build an inner shed and make a special trip to put on "warm clothes" for the most frozen vegetables such as Hangzhou cabbage and lettuce. It has been calculated that the inner shed can help vegetables withstand the low temperature environment approaching -5°C. However, the construction of the inner shed was time-consuming and laborious, requiring several workers to work together to build the steel pipes and sort out the plastic film. The reserved space should not be too small, and the vegetables should be allowed to "breathe" and grow freely, and should not be too large, otherwise it will not have the effect of heat preservation. After laying the amount in advance, Yan Zhonghua completed the reinforcement of the inner shed before the arrival of the cold wave.

In response to the cold wave, he was still not at ease, and carefully inspected the vegetable greenhouses in the base from the inside out. Whether the door seams at the entrance and exit of the greenhouse are tightly closed, and whether there is a small tuyere at the top of the greenhouse...... He knows very well that once the plastic greenhouse is torn open by the wind, the consequences are unimaginable. "When the sight is still good before sunset, find the hidden details in time and repair and deal with them. ”
