AI Technical Summary

Technical Problem

Existing water collection and drainage devices for soft soil foundation reinforcement treatment suffer from reduced drainage performance due to silt blockage, and the lack of effective silt removal mechanisms affects construction progress and costs.

Method used

A water collection and drainage device including a cleaning mechanism and a sludge suction mechanism was designed. High-pressure gas pushes the sealing ring and extension ring downward, and the sludge suction mechanism sucks out the sludge, realizing online cleaning of the filter tube surface and preventing clogging.

Benefits of technology

It effectively prevents sludge buildup on the surface of the filter pipe, keeps the drainage channels unobstructed, extends the working time of the device, avoids a decline in drainage performance due to sludge blockage, improves construction efficiency and reduces costs.
