The Yangtze River Daily Da Wuhan Client July 15th (Reporter Yang Sihan Correspondent Xie Minghui) On the 14th, Wuhan's highest temperature was as high as 38 degrees Celsius, the air was sultry, and people were sweating for five minutes on the outdoor station. At 8 am, Xia Dazhang, deputy director of the Maintenance Engineering Division of the Wuhan Water Supply Group of Wuhan Water Affairs Group, rushed to the Huajin Garden community in the district half an hour in advance to check the leakage point. It turned out that the community reported this morning, and the high -level residents reported that during the two days of water peak hours, the amount of water in the home was small and affecting life.

The 3rd and 4th phases of the Huajin Garden community involve 8 control valves. Due to the specific location of the omissions, each valve needs to be closed in turn, and the water pressure changes of the community's supercharged pump pumps are simultaneously observed simultaneously to gradually reduce the scope of the leakage point inspection.

To close the valve, two people need to cooperate to rotate the valve key more than one meter together. The reporter from the Yangtze River Daily saw at the scene that Xia Dazhang and his colleagues carefully pointed the key to the valve holes, and rotated the key clockwise together. At this time, the scorching sun in the sky, Xia Dazhang's eyebrows and nose tips exuded a lot of sweat, along the cheeks, " "Pick up" down.
