AI Technical Summary
Technical Problem
In existing technologies, the effluent from rainwater wells contains silt and sand, which causes siltation and blockage in drainage pipes, and the uneven stress on different parts of the drainage ditch causes localized erosion.
Method used
A dual-layer flow equalization filter distributor is adopted, including a porous filter plate and a micro needle rib filter, combined with a check valve and a control valve, to achieve uniform distribution of deep groundwater and prevent sediment deposition, forming a unidirectional hydraulic connection.
Benefits of technology
It achieves a balanced distribution of hydraulics across the entire slope, preventing localized scouring and siltation, reducing operation and maintenance costs, and improving construction safety and efficiency.
