Underground three-dimensional water interception and drainage prevention and treatment structure for oversize deep landslide and construction method thereof
The structure comprises a seepage interception wall arranged on the rear edge of the landslide, an underground water interception tunnel is arranged behind the seepage interception wall, and the underground water interception tunnel is arranged in a sliding bed below a sliding zone. A plurality of drainage shafts are arranged between the rear of the seepage interception wall and the underground water interception tunnel, and connecting branch tunnels are arranged at the bottoms of the drainage shafts and intersect with the underground water interception tunnel; a drainage hole is formed in the top of the underground water interception tunnel; a plurality of underground drainage holes are formed in the landslide body from top to bottom, and drainage holes are formed in the tops of the underground drainage holes. According to the method, trailing edge interception and drainage and slope body drainage are adopted, the seepage interception wall, the drainage vertical shaft, the underground water interception tunnel and the drainage hole are arranged on the trailing edge of the landslide, supply of the landslide by trailing edge mountain underground water is cut off, then the underground drainage tunnel and the drainage hole are formed in the landslide body, the landslide underground water is further drained, the landslide underground water level is lowered to the maximum extent, and the landslide effect is improved. The overall landslide stability is improved.
本发明公开了一种特大型深层滑坡地下立体截排水防治结构及其施工方法，该结构包括在滑坡后缘设置的截渗墙，截渗墙的后方设置有地下截水洞，地下截水洞设置在滑带下方的滑床内，截渗墙的后方与地下截水洞之间设置有若干个排水竖井，排水竖井底部设置连接支洞与地下截水洞相交；地下截水洞的顶部设置有排水孔；滑坡体内自上而下设置有若干个地下排水洞，地下排水洞的顶部设置有排出孔。本发明采用“后缘截排，坡体疏排”，通过在滑坡后缘设置截渗墙、排水竖井、地下截水洞和排水孔，截断后缘山体地下水对滑坡的补给，再通过在滑坡坡体内设置地下排水洞和排出孔，进一步疏排滑坡地下水，最大限度的降低滑坡地下水位，提高滑坡整体稳定性。
