软式排水管 Flexible drainage pipe

软式排水管软式排水管是由涂布合成树脂覆盖物的金属弹性螺旋线圈,在该线圈外周隔离并依其轴线方向配置的纵线,以及在纵线外周呈螺旋状卷绕重叠的横线所构成,前述纵线另渗附合成树脂粘合剂,在该线圈及横线相互交接处熔合成一体,形成三者一体的排 水管,同时在管体外周呈波峰和波谷轮流的凹凸,且 管体具有可挠性,在长度方向可伸缩自如.前述排水 管进一步可在管体下半周涂布合成树脂,使下半周成 为不透水状态,以防管内的水再渗回土壤中.软式排水管对地下排水、边坡排水起到了关键性的作用。

A flexible drainage pipe is composed of a metal elastic spiral coil coated with a synthetic resin coating, a longitudinal line that is isolated around the coil and arranged in the direction of its axis, and a horizontal line that is spirally wound and overlapped around the circumference of the longitudinal line. The aforementioned longitudinal line is additionally infiltrated with synthetic resin adhesive, and fused into one at the intersection of the coil and the horizontal line, forming a drainage pipe that integrates the three. At the same time, there are concave and convex peaks and valleys in the outer circumference of the pipe, And the pipe body is flexible and can expand and contract freely in the length direction. The aforementioned drainage pipe can further be coated with synthetic resin in the lower half of the pipe body, making the lower half of the pipe become impermeable to prevent water from seeping back into the soil. The soft drainage pipe plays a crucial role in underground drainage and slope drainage.
