Cutting slope long-acting drainage structure and construction method
The invention discloses a cutting slope long-acting drainage structure and a construction method. A large-scale slope body collapse disaster is caused by unsmooth drainage of a slope body due to rainfall of a rock-soil body slope in nature, and the engineering safety is seriously influenced. The outermost layer is a high-strength PVC pipe, and rectangular through holes are formed in the outer wall of the high-strength PVC pipe; and a capillary drainage plate and an inner-layer PVC pipe are arranged in the outer-layer high-strength PVC pipe, and the capillary drainage plate wraps the outer surface of the inner-layer PVC pipe and is clamped into a longitudinal open groove in the inner-layer PVC pipe. During construction, the outer-layer PVC pipe is firstly installed in a slope drill hole, and then the PVC pipe wrapped by the capillary drainage plate is inserted into the outer-layer PVC pipe. According to the cutting slope long-acting drainage structure, a double-pipe structural form of fixing the high-strength PVC pipe on the outer layer, replacing the capillary drainage plate in the middle and replacing the PVC pipe on the inner layer is adopted, the capillary effect is fully utilized, and the effect of long-acting drainage of the side slope is achieved.
本发明公开了一种路堑边坡长效疏排水结构及施工方法。自然界中岩土体边坡常因降雨坡体排水不畅诱发规模较大的坡体塌滑灾害，严重影响工程安全。本发明最外层为高强度PVC管，外壁上设置有长方形通孔；外层高强度PVC管内设置有毛细排水板和内层PVC管，毛细排水板包裹于内层PVC管外表面，并卡入内层PVC管上的纵向开槽内；施工时，先将外层PVC管安装进边坡钻孔内，再将包裹毛细排水板的PVC管插入外层PVC管。本发明采用外层固定高强度PVC管+中间可更换毛细排水板+内层可更换PVC管的双管结构形式，充分利用毛细效应，起到边坡长效疏排水的作用。
