Description

[0002] Slope interception and drainage is an important link in foundation pit engineering, aiming to control the influence of underground water and surface water on the slope to ensure construction safety and slope stability.

[0003] The existing slope drainage device inserts a plastic pipe into the slope at an angle to discharge soil pore water, wherein the plastic pipe is filled with filter material to prevent soil particles from flowing out. Since the filter material is directly squeezed into the plastic pipe without any limiting measures, the long-term scouring of water flow can cause the filter material to loosen or even be carried away by the water flow, resulting in soil entering the pipe and causing blockage.

[0004] Therefore, how to optimize the filtering structure of the drainage device to achieve interception and filtration of water flow and prevent the filter material from being washed away is a technical problem that needs to be solved in the design of the slope drainage device.

[0015] Preferably, the water inlet part comprises water inlet holes, and a plurality of water inlet holes are arranged around the outside of the drain pipe body.

[0016] Preferably, the connecting part comprises:
