Transverse drainage pipe for long-distance water supply channel and using method of transverse drainage pipe
The invention discloses a long-distance water supply channel transverse drainage pipe and a using method thereof, and the water supply channel transverse drainage pipe comprises a curve drainage pipe, a geomembrane and a one-way check valve; the one-way check valve is arranged at the tail end of the curve drainage pipe, the geomembrane lining is arranged on the upper surface of the curve drainage pipe, the curve drainage pipe comprises a plurality of sections of water filtering steel pipes, plum-blossom-shaped holes are formed in the upper semi-circumferences of the water filtering steel pipes, and the plum-blossom-shaped holes are lined with polypropylene fiber yarn geotextile, namely the geomembrane, supported by a spiral steel wire framework. The transverse drainage pipe of the long-distance water supply channel is placed on a water seepage layer of the channel through a pipe jacking machine, and seepage water of the channel is collected and discharged to the bottom of the channel through the water filtering steel pipe, so that the effect that the upper-layer pressure of a rigid lining layer of the channel is larger than the lower-layer pressure is achieved, and then the technical effect of guaranteeing channel lining and slope safety is achieved.
本发明介绍了一种长距离供水渠道横向排水管及其使用方法，其中，供水渠道横向排水管包括曲线排水管、土工膜以及单向逆止阀；所述单向逆止阀设置在曲线排水管的末端部，土工膜内衬在曲线排水管的上表面，所述曲线排水管包括多节滤水钢管，所述滤水钢管的上半圆周上设置有梅花状孔洞，梅花状孔洞内衬有螺旋钢丝骨架支撑的丙纶丝土工织物即土工膜。使用顶管机器将本申请设计的长距离供水渠道横向排水管放置在渠道渗水层，通过滤水钢管将渠道下渗水进行收集，并排到渠底，以此实现渠道刚性衬砌层的上层压力大于下层压力，进而实现保障渠道衬砌和边坡安全的技术效果。
