In January this year, Huai'an City, Jiangsu Province experienced a cold wave of the century, with a minimum temperature of -13°C. Cold weather, 340,000 users in urban areas are facing severe challenges. From January 23 to January 30, the water supply service hotline “962001†of the Municipal Water Supply Co., Ltd. received an unprecedented number of reports from over 16,000 urban residents for repairs and consultations. There were 10,000 meter explosions in the urban area and more than 40 pipelines. Explosion. The explosion of the district, the bursting of the table, the provision of water by the public, the dripping of ice from the corridor, the hanging ice from the balcony, etc., can be seen everywhere. After the cold wave, the Urban Housing and Urban-Rural Development Bureau, the Urban Council, and the Water Company quickly replaced the 20,000 burst water meters during the cold wave.
"This year, we do not rule out the possibility of resembling extremely cold weather again, and take preventive measures beforehand." Secretary of the Municipal Council Miao Deqin admitted that at present, the city's water company has dispatched a repair team to inspect exposed outdoor water pipes and damaged some of them. Water pipes are repaired in time. Before the advent of winter, 350,000 water meters and related pipelines in the urban area will be protected from frost and similar situations in the urban area at the beginning of this year will be avoided to ensure safe water supply facilities for the winter.
Many measures Baocheng “lifeline†security old community into a protective focus It is reported that, with the advent of winter, the temperature gradually decreased, the city water supply security situation has become a common concern of the people. The Huai'an Urban Construction Bureau and the Urban Council will work hard to improve the quality of water supply, water supply capacity and service levels in the winter, and ensure the safety of the city's "lifeline" with all-round and full-flow measures.
The Municipal Housing and Urban Development Bureau and the Urban Council have attached great importance to, carefully planned, and fully prepared to earnestly do a good job in winter water supply safety work. All maintenance teams and construction sites have conducted comprehensive safety inspections in advance, strengthened guardianship measures, and stood by 24 hours a day to ensure 24-hour emergency repairs. . Once the water supply pipeline is damaged, the maintenance team will arrive at the site the first time, overcome difficulties in repair, repair in a timely manner, and restore the safe operation of the pipeline network, so that “risk will be robbed and dealt with in a timely mannerâ€.
The municipal water supply company has formulated antifreeze guarantee work plans for winter water supply pipelines and ancillary facilities, established a three-tier early-warning mechanism for antifreeze in winter, and set up an emergency repair command post, which consists of 14 working groups such as repairing water meters and repairing pipe networks.
According to the experience at the beginning of the year, among the 350,000 water meters and related pipelines of the “antifreezeâ€, the old district is a key protection area. Yesterday afternoon, in Building 2 of the residential building of the Paradise Building, staff of the Municipal Water Supply Company was protecting the external water supply pipes. According to Liu Jun, leader of the maintenance team of the city's water company, the first two centimeters of insulation wool was added to the water supply pipe, and the outer part was wrapped with tin foil to ensure the maximum protection of the water supply pipe. Citizen Jiang Zhaolin saw this scene and was happy to have a flower. "This is the bottom of my heart. I have lived here for 12 years. When I freeze in winter, it becomes bad once it is frozen. Draught has become a big problem. With these protective measures this year, I am not afraid that the water pipes will freeze again," said Jiang Zhaolin.
The power plant river community on Qianjin Road is also an old district. The reporter saw yesterday afternoon that the staff of the water company dumped a large amount of rice bran into the square well where the water meter was buried. Xiao Shui, director of the water supply department of the city's water company, told reporters that after the weather is cold, the water meter covering the rice dumplings is like a quilt, which can keep it warm and cold, and greatly reduce the risk of freezing the water meter.
Xia Yonghu, deputy director of the Urban Council, introduced that in the beginning of this year, a total of more than 70 water pipelines were broken down in the urban areas. Currently, over 30 repairs and replacements have been made. It is expected that all repairs will be completed in the next 15 days.
Water meter "warm" Tips, how to prevent outdoor pipe antifreeze?
First, use old clothes and old cotton wool to tightly wrap exposed pipes and faucets, and add a layer of plastic film or other waterproof material on them. The pipe elbows or joints must be wrapped and wrapped tightly.
How to freeze the indoor pipe?
Go in and out of the corridor to close the window and make sure that all doors and windows in the public stairway are closed. At the same time, the doors and windows in the home must be closed. If the daytime temperature is lower than 0°C and the nighttime temperature is lower than -5°C, turn on the tap to keep the tap water flowing. If the house is temporarily unoccupied, the indoor water main valve should be turned off.
·How to freeze the outdoor water meter?
The water meter embedded in the wall or installed in the pipe well can be used to wrap the front and rear pipes tightly with old clothes. At the same time, the inside of the table box is stuffed with insulation material to tightly seal the door of the watch box so as not to allow cold air to enter. For buried underground water meters, fill the water meter box with fine sand, rice hulls, and old cotton wool, and close the cover of the meter box.
·What are the thawing methods for water supply facilities?
For frozen water pipes, try wrapping the frozen parts with a towel, and repeatedly and slowly pour with warm water. Do not use the fire to bake directly. Since the surface of the water meter is made of glass, do not use hot water to cook.
·Do you need to store water in your home beforehand?
Very necessary. Although anti-freezing measures are taken, the water supply facilities may still be frozen, and once frozen, it will be difficult to solve them in a short time. In order to make life at home not be affected too much, it is recommended that citizens prepare for water storage in advance.
What should I do if the water meter freezes?
For the residential or residential areas that are managed and maintained by the water company, citizens can call the 24-hour water service hotline “962001†and must not replace the water meter by themselves in case of damage to the pipeline.
