Problems solved by technology

[0003] However, due to the large buried depth of the water storage main pipe, the gas in the system may not be able to discharge freely, and at this time, the phenomenon of pressure oscillation and gas-liquid mixed flow impact will be inevitable
At present, the pipes in the drainage system are designed acc
