Construction method of giant anti-slide pile structure
A construction method of a giant anti-slide pile structure relates to the technical field of anti-slide piles, and adopts the technical scheme that the construction method comprises the following steps: S1, preparing an anti-slide pile framework, S2, measuring, positioning and drilling, and tripping in a micro-core pile pipe and a micro-wall pile pipe, S3, dividing the anti-slide pile framework into a plurality of sections, and sequentially performing micro-wall pile pipe grouting, connecting hole drilling and micro-core pile pipe grouting on each section from bottom to top, and S4, pouring a pile platform. The multiple micro-wall pile pipes are distributed around the micro-core pile pipe, the connecting holes are drilled between the micro-wall pile pipes and the micro-core pile pipe, hardened layers are formed in the micro-wall pile pipes and the micro-core pile pipe after grouting, the horizontal supporting beams are formed in the connecting holes, the framework structure is formed through connection, and the bearing capacity of the structure is improved; and in combination with grouting, a crack filling layer is formed around the micro-wall pile to enhance the stability of a rock-soil layer, so that the construction difficulty and cost of an anti-sliding structure in huge landslide control in a hard area are reduced.
一种巨型抗滑桩结构施工方法，涉及抗滑桩技术领域，所采用的技术方案包括S1准备抗滑桩骨架，S2测量、定位，钻孔并下入微芯桩管和微壁桩管，S3将所述抗滑桩骨架分为多段，从下到上每段依次执行微壁桩管注浆、钻连接孔、微芯桩管注浆，S4，浇筑桩台。本发明将多个微壁桩管围绕微芯桩管分布，并在两者之间钻连接孔，注浆后微壁桩管、微芯桩管内部形成硬化层，连接孔内形成水平支撑梁，连接成骨架结构提升了结构的承载能力，并结合注浆在微壁桩周围形成裂隙填充层加强岩土层的稳定性，从而降低了艰险地区巨型滑坡治理中抗滑结构的施工难度和成本。
