Landslide emergency disposal method based on failure of existing retaining structure
The invention discloses a landslide emergency disposal method based on failure of an existing retaining structure, which comprises the following steps of: arranging two open drainage ditches on the outer side of a landslide area by 5m, and cutting off a supply path of an external water body to a slope body; two drainage blind ditches are transversely arranged on the slope surface of the landslide area, the bottoms of the ditches are compacted through clay, the bottoms and the backwater sides of the ditches are poured through reinforcing mesh concrete, the thickness is 15 cm, the ditches are backfilled with broken stones and pebbles, and the upper portions of the ditches are covered with soil; horizontal drainage holes are formed in the water facing side of the blind ditch 50 cm away from the ditch bottom every 5 m in the slope body direction, a potential sliding face is uncovered and penetrated, floral tubes are arranged in the horizontal drainage holes, hard permeable pipes are inserted into the floral tubes, and fine sand is poured into pore parts; two rows of horizontal drainage holes are formed in the slide-resistant pile inter-pile plate part in the slide-resistant pile non-failure area; the disturbance to the slope body is small, the construction safety risk is small, the drainage blind ditches and the drainage holes are buried underground, the original landform can be restored after construction is finished, cultivated land is not occupied, and the method is suitable for landslide treatment in the deformation stage.
本发明公开了一种基于既有支挡结构失效的滑坡应急处置方法，包括如下步骤：在滑坡区外侧5m布置2条排水明沟，截断外部水体对坡体的补给路径；在滑坡区坡面横向布置两条排水盲沟，沟底采用黏土压实，沟底及背水侧采用钢筋网片混凝土浇筑，厚度15cm，沟内采用碎石、卵石回填，上部覆土；在盲沟迎水侧距沟底50cm每间隔5m向坡体方向设置水平排水孔，揭穿潜在滑面，水平排水孔内插花管，管内插入硬式透水管，孔隙部分灌入细砂；在抗滑桩未失效区抗滑桩桩间板部位布置2排水平排水孔；本发明对坡体的扰动小，施工安全防风险小，排水盲沟、排水孔均埋置于地下，施工结束后可恢复原始地貌，不占用耕地，对处于变形阶段的滑坡治理较为适用。
