Xinhua Full Media+丨 "Post -90s" listening to leakage: "auscultation" for urban water supply pipelines

On July 23, Zhang Yang conducted normalized inspections on a section of Shushan District, Hefei.

Zhang Yang, 29, is the captain of the "Lei Feng Spirit" of Hefei Water Supply Group in Anhui. He led 23 team members and was responsible for the leakage of more than 10,000 kilometers of water supply pipe networks in the city.

The "dealing" with the sound is the daily work of Zhang Yang and colleagues. The vibration sound of the pipeline, the sound of leakage, the collision between the sand and the stones, the leakage of the noise of the surrounding sand and stones, etc. passing the leakage rods and leakage instruments, etc. The characteristics of the other, accurately analyze the levels and diversity of sounds, so as to determine whether water leakage and accurate positioning.

In the past four years of work, Zhang Yang shuttled on the streets of the city and used both ears as the urban water supply pipeline network. Under his leadership, the "Lei Feng Spirit" leaking team has detected more than 6,000 missing points in the past four years, with an accuracy of 99.8%, and saving more than 77 million tons.
