Construction method of drainage and skid resistance combined structure for extra-large landslide disaster
The invention provides a construction method of a drainage and skid resistance combined structure for an extra-large landslide disaster. Based on fluid mechanics, solid mechanics, a hydrodynamic model, a structural model and an engineering geologic model, the whole-set construction method of the drainage and skid resistance combined structure for the extra-large water-rich landslide disaster is researched. Firstly, a small-caliber pile capable of mechanically and rapidly forming holes is utilized, and a retaining wall of a drainage anti-sliding structure is formed in a circular arrangement mode; secondly, internal prefabricated lining segments are manufactured and installed, and permeable holes and drainage floral tubes are preset on the surface layers of the segments; a reinforced concrete anti-sliding key is additionally arranged near the sliding surface; and finally, a multi-branch directional drilling process is utilized, and the inclined drainage pipe and the drainage anti-sliding structure are combined to form a seepage-collection-drainage anti-sliding combined three-dimensional structure system. The invention belongs to the technical field of geological disaster prevention and control safety, particularly relates to technologies such as light small-caliber pile treatment and non-excavation directional drilling, and can be widely applied to rapid treatment of extra-large water-rich landslide disasters about to be unstable and deformed or being deformed.
本发明提供了一种特大滑坡灾害排水抗滑组合结构施工方法。本发明基于流体力学、固体力学、水动力模型、结构模型、工程地质模型，研究了针对特大富水滑坡灾害的排水抗滑组合结构成套施工方法。首先利用可机械化快速成孔的小口径桩，采用“圆形”布置形成排水抗滑结构的护壁；其次制作安装内部预制衬砌管片，管片表层预设透水孔及排水花管；然后在滑面附近增设钢筋混凝土阻滑键；最后利用多分支定向钻进工艺，将仰斜排水管与排水抗滑结构组合形成“渗‑集‑排”抗滑组合立体结构系统。本发明属于地质灾害防治安全技术领域，具体涉及轻型小口径桩治理，非开挖定向钻进等技术，可广泛适用于即将失稳变形或正在变形的特大富水滑坡灾害的快速治理。
