Auditors deal with sounds, auscultation for water supply pipes! What is the day to day job like?

Zhang Yang is the leader of the leak listening team of the Hefei Water Supply Group, and he has 23 team members under him, who are mainly responsible for the leak detection of the city's water supply network. They deal with sound, they have to rely on the sound of pipe vibrations, water leaks, sand and gravel collisions, and so on. Through the leakage meter, the leakage rod and some professional instruments, the sound is transmitted to the ear, and then the sound is analyzed according to the characteristics of the tube and the environment.

Determine whether there is a water leak, and if there is a water leak, it is necessary to accurately locate the leakage point. <>

Therefore, Zhang Yang has been shuttling through the streets and alleys since he worked, using his ears to check the pulse of the city's water supply network. In four years, his team has detected more than 6,000 leaks, achieved positioning accuracy, and saved more than 70 million tons of water. Leak listening worker, this is a special type of work in the water pipeline, mainly using the leakage equipment to detect whether the water pipe is leaking.

And the working hours are in the middle of the night, so working in this industry requires special ear sensitivity. <>

Moreover, it has to go through a very hard training, and the leakage worker has a great effect on whether the water supply in the city is smooth, and it can guarantee the conservation of water resources. If it's just a job of listening to leaks, then it's relatively simple, and it can be said that everyone can do it. However, if you want to accurately locate the leakage point of the pipeline, it is a technical job, which requires great experience and high understanding.

And it takes at least a year or so to be able to become a teacher, and some people even have to study for three or four years. <>

They determine the location of the leak by the sound of the leak and the friction with the surrounding area. Moreover, the material, depth, direction, and size of the water pipes are all different, so the sound of water leakage is also different. Although the equipment is now relatively advanced, the instrument is only an auxiliary role.

If you want to find the exact leak point, the main thing is to test their listening skills. If you don't have a lot of experience and professional knowledge, you can't do it easily.

My daily life is to work in the sewer pipes, which are often dirty and do not look like people at all.

I usually start work at 8 a.m. and go straight into the water pipe to listen to the sound of the water leak. The general salary is also quite high, about 8,000 yuan.

The daily routine of this job is to get up at 5 o'clock in the morning, and it also needs to smell a particularly bad smell, and every day you need to lie on the ground with gloves.
