Baoding "Stunning Night": Water supply supervisor explosion, more than 300 people race with time

On the morning of July 13th, the water supply repair site of the intersection of Shuiyuan Road and Le Kainan Avenue, in the work pit of 10 meters and 6 meters wide, accurately measured the pipeline size while facing the pipeline, and hugged for the follow -up to follow the pipelines. Card production and fast installation lay the foundation. This is the mark left after a night of fighting.

At 9 pm on the 12th, a number of citizens reported that the water stopped at home. Immediately, a video of "Baoding's water pipe runs water, water is like spring, and the road becomes the ocean."

Accidental repair site

The water supply and pipes are running out of water, and the water consumption in the urban area is affected

"The pressure of the scheduling system shows that the pressure near the surface water plant suddenly decreases. The pipeline of the large pipeline may occur. The personnel of the pipe network repair the duty team immediately went to investigate. The remaining departments were prepared in advance in accordance with the plan requirements."

At 21:46 on the evening of July 12, one of the two DN1400 main pipelines in the urban area of ​​the first surface water plant in Baoding City suddenly had a sudden explosive tube failure, the water source was leaked, the situation was critical, and the water supply pressure in the urban area was rapidly reduced. Water stopping.

It is related to the city's water, and Baoding Water Supply Co., Ltd. (hereinafter referred to as water supply companies) After rapid screening of water supply abnormalities, the first -level first -level emergency plan was launched, and more than 300 cadres and employees immediately rushed to the scene.

This will be an unnounted night for water supply.

Accidental repair site

The three valves were flooded, and the turns under 2 meters deep under well well

The accident water pipe is one of the two main pipelines for water supply to the urban area of ​​the first surface water plant. Due to the large running water at the scene, the nearby gates well were flooded, and the intuitive judgment could not be determined.

In order to solve the water output situation as soon as possible, the repair personnel gave full play to the role of intelligent water supply platform, and used advanced positioning equipment to quickly find the gate on both sides of the damaged main pipeline.

How to close the valve is a new problem.

"Bringing the gates is very strenuous. If the operation is too fast, it will cause the water pressure inside the pipeline to rise sharply or decreased. There are hidden dangers of the second explosion. It may take half an hour. "Li Jinzhong, the director of the Restaurant of the Water Supply Network, told reporters.

Under 2 meters deep, the maintenance staff worn the protective tools and worked hard to twist the valve. Due to the gradually increased pressure in the tube, the difficulty of operation gradually increased. In the narrow space, several maintenance personnel took turns in turn. Although it was late at night, the continuous high temperature work still made the maintenance staff sweat.

Accidental repair site

After nearly 2 hours of work, all three valves were closed, and the leakage of the pipeline was effectively suppressed.

As of 23:40 on the 12th, the water supply pressure in the urban area quickly recovered to 0.19-0.25MPa, and the basic living water for residents was guaranteed.

"The urban area has now formed a relatively comprehensive ring water supply network system. This pipeline fails can also be continued by another main pipeline. At present The hydration and pressure, the water pressure affected by the affected area is gradually returning to normal. "Li Jinzhong said.

Raising personnel conduct pipeline repair

More than 300 people fought at night to repair, and recovered road traffic overnight

Due to the damage of the pipeline, a large amount of water sources surged on the street. In order to ensure that road traffic recovers as soon as possible, more than 300 employees cleaned the road area of ​​water overnight and excavated work pits for pipeline repair.

"Large -caliber pipeline holding cards need to be manually welded according to the actual size of the pipeline. The workers have worked overtime and overtime after the size. reporter.

The test center conducts water quality testing

In addition, in order to further ensure the safety of water quality in the urban area, the staff of the water supply laboratory center also sampled the sampling point of the east, south, west, and north of the urban area. According to the test results, the water quality of each region is currently fully qualified.

As a urban water supply company, for many years, Baoding Water Supply Co., Ltd. has always made every effort to ensure the use of water and production water in urban areas as the core point, establish and improve the emergency guarantee mechanism, achieve multi -dimensional safety operation control, strengthen the team's rescue capabilities, and set up well. Many water supply incidents caused by violations of regulations and barbaric construction have strongly defended urban water supply safety.

In the early morning of July 9, 2011, the DN1400 water supply pipeline of Lekai Street ran out of water, causing the pressure of urban pipeline networks. The reason is that above the pipeline is pressed by illegal houses, causing the pipeline pressure to be overweight.

On the afternoon of April 8, 2014, the DN1200 water supply pipeline of Limin Road ran out of water, causing the pressure of urban pipeline networks to decline. The reason is that a construction unit is savage.

At noon on April 13, 2016, the DN1400 water supply pipeline of Limin Road ran out of water, causing the pressure of urban pipeline networks. The reason is that above the pipeline is used by the material warehouse, causing the pipeline pressure to be overweight.

On the morning of March 22, 2017, the PE630 water supply pipeline of Lekai Street ran out of water, causing the pressure of urban pipeline networks to decline. The reason is that a construction unit is savage.

Baoding Water Supply reminds the majority of construction units to build a civilized and orderly construction to ensure the safety of urban water supply.
