AI Technical Summary
In existing water conservancy projects, the pumping efficiency of the foundation pit support structure is reduced during pumping because air flow occupies the negative pressure space inside the water tank.
The design incorporates evenly distributed inlets and filter heads on the surface of the drainage pipe, utilizing the pore water pressure in the soil to directly force water into the drainage pipe, preventing air from entering. Combined with the insert plate and bonding plate structure, it achieves efficient drainage, and the foundation pit is reinforced with concrete after construction.
It improved pumping efficiency, avoided negative pressure loss, and enhanced the stability of the support structure by reinforcing the foundation pit with concrete.
