Anti-landslide structure of strip mine dump and construction method of anti-landslide structure
The invention discloses an anti-landslide structure of strip mine refuse dump and a construction method thereof, the anti-landslide structure comprises a plurality of layers of refuse dump distributed in a step shape, the top surface of each layer of refuse dump is V-shaped, and a plurality of drainage well pipes are vertically and uniformly distributed on each layer of refuse dump along the length direction; the method has the beneficial effects that the drainage well pipe is designed at the initial stage of the design of the waste dump, the height of the drainage well pipe is flexibly increased along with the proceeding of the dumping of the waste dump, the grouting pipe is designed in the drainage well pipe, and the high-pressure concrete is injected into the grouting pipe, so that the shear resistance in the waste dump is greatly improved; the phenomena of slippage and dislocation in the waste dump are prevented, and the occurrence of landslide accidents is fundamentally eradicated.
本发明公开了一种露天矿排土场的防滑坡结构及其施工方法，其包括呈阶梯状分布的若干层排土场，每层所述排土场的顶面均为V型，在每层排土场上沿长度方向均布的竖直设置有若干个排水井管；本发明的有益效果：本发明在排土场设计初期即设计排水井管，随着排土场排土的进行，灵活的增加排水井管的高度，并在排水井管内设计注浆管，在注浆管内注入高压混凝土，极大的提高的排土场内部的抗剪切能力，防止排土场内部发生滑移、错动现象，从根本上杜绝了滑坡事故的发生。
