Wang Siwen. Carrying a long listening rod, pry open each manhole cover, and listen carefully to the sound of running water in the water valve......In the city, there is such a special group of "auscultation doctors" who use their ears to "auscultate" the city's water pipes.
Zhao Bin, head of the leak detection section of the Pipe Network Surveying and Mapping Department of Shenyang Water Group, is one of them. In the blink of an eye, he has been in this position for 32 years.

At 9 a.m. on February 10, next to a manhole near Yunfeng Street in Tiexi District, Zhao Bin was quietly lying on the ground listening to the sound of water flowing in the underground pipe network. Before that, he and other members of the leak detection team had already inspected a number of manholes. Lift the manhole cover again and again, and reset it again and again.
In the cold winter, hats, gloves, cotton coats, sledgehammers, hooks, listening rods, flashlights, and various special equipment for leak detection are the standard equipment for leak detectors to go out to the scene. Zhao Bin told reporters that the leak detection work is more complicated, especially in some large communities, sometimes it is necessary to check dozens or even hundreds of manholes in order to finally lock the leakage point. And lying on the ground with a listening stick is also a must for work. "Lying in the snow in winter and lying on the ground in summer is the daily life of every leak tester. ”
Due to the noisy vehicles and the outside environment during the day, in order to avoid noise interference and large traffic flow, many leak detection needs to be done at night. Zhao Bin and his co-workers often inspect and test leaks along the water supply pipeline in the middle of the night, lifting rows and rows of manhole covers weighing dozens of kilograms, and the carpet inspection will be done until dawn.

Residents have difficulty in using water, and we are going to be there. Zhao Bin said. On the 28th day of the lunar calendar last year, when everyone was immersed in the festive atmosphere of welcoming the Spring Festival, a high-rise residential building in Yuhong New Town was unable to use water. Due to the inconsistency between the pipe network drawings and the actual pipeline location on site, the leakage detection work is very difficult. Zhao Bin said: "At that time, we quickly formulated a testing plan according to the on-site situation, tested all the water supply networks in the park, braved the severe cold for two days, and finally found the leak on the night of the 29th of the lunar month. ”
Lu Zhenghai, 58, is a colleague of Zhao Bin. For him, who has been engaged in pipe network maintenance for 21 years, it is common to be on duty during the Spring Festival. "I have been engaged in pipe network maintenance for 21 years, and I spend almost every Spring Festival in the unit, and my family is used to it. Lu Zhenghai said.
During the Spring Festival, my family and friends gathered for dinner, but I didn't dare to agree. Lu Zhenghai said that one year during the Spring Festival, he promised to go to his brother's house for dinner, but in the end he didn't go to it because of emergency repairs. After all, since he was engaged in pipe network maintenance in 2003, he basically did not have a good Chinese New Year's Eve meal with his family. "On Chinese New Year's Eve, cooking dumplings in the unit with my brothers is also quite joyful. ”

Lv Zhenghai is an inspector of pipe network equipment and facilities of the Tiexi Business Branch of Shenyang Water Group. Many people say that he is a "living map" of the pipe network, no matter which pipeline in the area, he can accurately tell the pipe diameter, direction and other relevant information.
More than half a month before the Spring Festival, my colleagues and I have conducted a comprehensive investigation of the fire hydrants and water supply pipe networks in important streets and areas in Tiexi District, just to make the water supply stable for every household during the Spring Festival. Lv Zhenghai said that even so, in order to prevent emergencies, maintenance personnel are still on duty.
