Slope negative pressure drainage structure, construction method and use method
The invention provides a side slope negative pressure drainage structure, the hole bottom elevation of a negative pressure drainage hole is lower than the safe underground water level line elevation of the area, and the side slope is further provided with a high-position gas collecting and water supplementing tank and a low-position pressure maintaining water tank which are higher than and lower than the hole opening elevation of the negative pressure drainage hole respectively; drainage channels are fixedly arranged in the negative-pressure drainage holes, drainage sections for guiding underground water flowing are formed between the drainage channels and the negative-pressure drainage holes, pipeline connecting pieces are installed at the ends, extending out of the negative-pressure drainage holes, of the drainage channels, and siphon drainage pipes are connected to pipe openings of the drainage ends of the pipeline connecting pieces; the downstream end of the siphon drain pipe is connected into the low-position pressure maintaining water tank. Through the drainage pipe and the siphon drainage pipe in the negative-pressure drainage hole, the drainage efficiency of the negative-pressure drainage hole in the slope can be effectively improved, and meanwhile the effective drainage amount is increased. According to the negative pressure drainage structure, the hydraulic gradient of underground water in the side slope is increased through negative pressure generated by siphoning, and the seepage rate is increased.
本发明提供了一种边坡负压排水结构，所述负压排水孔的孔底高程低于该区域安全地下水位线高程，所述边坡上还设置有分别高于和低于负压排水孔孔口高程的高位集气补水罐以及低位保压水箱；所述负压排水孔内固定设置有排水通道，所述排水通道在负压排水孔之间形成对地下水流动导向的排水段，且排水通道伸出负压排水孔端部上安装有管道连接件，所述管道连接件的排水端管口连接有虹吸排水管，所述虹吸排水管的下游端接入低位保压水箱内。本发明通过负压排水孔内的排水管以及虹吸排水管，可以有效提高边坡上负压排水孔的排水效率，且同时提高了有效排水量。该负压排水结构不仅通过虹吸作用产生的负压，增大了边坡内地下水的水力梯度，增加渗流速率。
