Underdrain drainage system, underdrain construction method and application
In order to overcome the defects in the prior art, the invention provides a blind drain drainage system, a blind drain construction method and application. The blind drain drainage system comprises a groove, a supporting body and a backfilling layer. The supporting body is laid at the bottom in the groove, and the cross section of the supporting body is in a local open shape or a circumferential closed shape. A plurality of through flow channels are formed in the side wall of the supporting body; and the cross section of the flow channel is fan-shaped, fusiform or concave waist drum-shaped. When the cross section of the support body is in a local open shape, the open area faces the bottom of the groove, and the enclosed internal area is a blind ditch; when the cross section of the supporting body is in a circumferential closed shape, the internal hollow area is the blind ditch. According to the blind ditch drainage system, the blind ditches are formed in the grooves in the mode that the supporting bodies are directly isolated, the flow channels are formed in the supporting bodies, and drainage and ventilation are achieved. Meanwhile, the blind ditch is large in cross section area, not prone to blockage, long in service life and suitable for many scenes. The blind ditch construction method is easy to operate and low in cost.
本发明为解决现有技术中存在的缺陷，提供一种暗沟排水系统、暗沟构筑方法及应用。该暗沟排水系统包括沟槽、支撑体和回填层。支撑体铺设于所述沟槽内底部，其横截面呈局部敞口形状或者周向封闭形状；在支撑体的侧壁开设有若干贯通的流道；流道的横截面呈扇形、纺锤形或者内凹式腰鼓形。支撑体的横截面呈局部敞口形状时，其敞口区域朝向所述沟槽的底部，合围内部区域即为暗沟；支撑体的横截面呈周向封闭形状时，内部中空区域即为暗沟。该暗沟排水系统中采用支撑体直接隔离的方式于沟槽内形成暗沟，并在支撑体上设置流道，实现排水、透气。同时，暗沟的横截面积较大，不容易堵塞，使用寿命较长，适用场景多。该暗沟构筑方法，操作简单，成本低。
