瑞琪渗排水管材在滑坡地下排水中的应用

传统滑坡的地下排水工程要么造价高、施工困难,要么效果不佳、容易堵塞。瑞琪管材是一种新型渗排水材料,其表面开孔率是传统管材的3～5倍,在60kPa以上压力下可保持50%～80%以上的内部孔隙率,渗排水性能优异,而且在外包土工布的情况下不会堵塞,从而解决了滑体中传统地下排水措施易压闭、堵塞导致失效的关键难题。将该管材运用于4个滑坡治理,已运行近4年,表现出了良好的集、渗、排水性能。

Application of Rich Drainage Materials in Underground Drainage Engineering of Landslide

Traditional underground drainage techniques in landslide control are usually expensive, difficult for construction, inefficient and stopped easily. Rich drainage material is a kind of new drainage material, its surface opens rate is 3-5 times to traditional drainage material. And it can keep the internal hole rate of above 50%-80% under the 60 kPas pressure. Because of the excellent drainage function, and not stopping in the circumstance of geotexture, the difficult for stopped esayly of traditional underground grainage engineering has been solved.This drainage material has been used in 4 landslides control engineering servering as underground drainage material, by running for four years, the drainage function of it is excellent as proved.
