What happens if the 1,000 mm diameter water supply main connection suddenly breaks and leaks, and it appears on the second day of the Lunar New Year? Nanjing Water Affairs, Traffic Management and other departments, as well as Gulou District, subordinate streets and other relevant personnel gave up their vacations, rushed to the scene as soon as possible, and fought all night for 16 hours, restoring water supply for the people within the promised time.
At noon on February 11, an emergency water outage notice issued by Nanjing Water Affairs Group attracted the attention of many people. According to the announcement, at 12:47 on February 11, the group received a report of water leakage in the east of the Huaimen Bridge, and immediately activated the emergency plan and arranged for gate operation and maintenance personnel to go to the scene. Due to the need for pipeline repair, Gupinggang (Huju North Road intersection), Shicheng Road (Mofan West Road - West Gate of Nanjing University of the Arts), including Qingjiang Flower Garden, Jiasheng Garden, Dinghuaimen No. 1-11, No. 2-6, Gupinggang No. 18-24 Community, Gupinggang No. 35, Jiangsu City College and other users have stopped water supply. It is estimated that the rehydration time will be at 5:00 on February 12, and the water will be supplied as soon as possible.
At noon on the same day, the monitoring system of the group's production dispatching center showed that the pressure index of the two water supply pressure monitoring points on Zhenghuai Road and Dinghuaimen Street plummeted, and the emergency repair instructions were sent to us. Zhong Xinggui, deputy director of the Management Institute of Nanjing Water Affairs Group, told reporters that after receiving the instructions, the staff on duty immediately activated the emergency plan, and he was also working on the emergency repair notice and rushed to the scene in time.
In order to let the public have no worries about water, we have prepared the Spring Festival water supply guarantee plan in advance, and carried out a multi-point layout of emergency repair personnel, vehicles and equipment, and during the Spring Festival holiday, 100 water supply pipeline repair personnel are on duty 24 hours a day at three sites such as Suojin Village, Beihekou and Yaoxin. Zhong Xinggui said that the emergency repair on the day was mainly based on the repair team of the Suojin Village site, but the staff on duty at Beihekou, Yaoxin and other sites also rushed to the scene at the first time, and the staff who were not on duty but could arrive at the scene within two hours also rushed over from home.
At 13:10 on the same day, after the gate was shut down and the maintenance personnel arrived at the scene, they immediately checked the water leakage, analyzed and judged the location of the leakage pipeline, and the three groups of staff carried out the work of closing the gate and stopping the water at the same time to ensure that the water was stopped in the fastest time.
At 13:32, the water stop was completed, and the excavation and repair work was immediately launched, and three excavators roared at the same time. Because the leakage point is located in the Dinghuaimen Street Expressway, the bottom of the water supply pipeline is about 8 meters from the ground, the excavation surface is large and deep, the repair personnel do a good job of the underground pipeline disclosure, and also do a good job of grading and supporting work before entering the underground excavation point to ensure safe construction.
At 22:00, the water supply pipeline finally revealed its "true face", which turned out to be a rupture of the connection between two pipes with a diameter of 1000 mm. The cause was identified, and pipeline repairs were immediately commenced. Zhong Xinggui introduced that according to the determined "double insurance" maintenance plan, the two pipelines were welded, and at the same time, a layer of reinforcement was carried out on the outer layer of the weld. Under the rotation of many welders, at 4:20 a.m. on February 12, the welding work was completed. At 4:50 a.m., the valve of the pipeline was opened to test the water, and after repeated observations, the water supply to the users was mechanically filled at the same time, and the water supply was restored at 6 o'clock in the morning for users in many communities along the line.
When the repair team was struggling to repair, the pipe network department and customer service department of the Municipal Water Affairs Group and other relevant forces also gathered at the scene in the fastest time. In order to provide water to the masses during the water outage period, 21 water supply trucks and 30 volunteers have been mobilized to carry out temporary water supply services for users in the water outage community with the cooperation of local streets and communities.
If you can't catch up with the evening rush hour water supply on the 11th, you must let the people use the water on the morning of the 12th. Zhong Xinggui said that aiming at this "goal", all the personnel at the scene were anxious and did not dare to stop for a moment, and after 9 o'clock in the evening of the same day, many emergency repair personnel remembered that they had not eaten dinner. "In the end, we finally beat the promised water supply time to the people, which is the best affirmation of our 16-hour battle. Zhong Xinggui said.
During the Spring Festival holiday, the all-night rush to repair the work also made the surrounding people full of emotion, "The masters of the water system worked tirelessly, and only the Jiasheng Garden Community sent three water trucks to continue to ensure the water ...... for the people from noon to night."After the emergency during the Spring Festival, I thought about the people, solved problems for the people in a timely manner, and sincerely felt the care and ......warmth of the party and the peopleOne resident sent a long "thank you note" to the local community.
