Full-casing full-rotation water stop secant pile for high confined water stratum and construction method of full-casing full-rotation water stop secant pile
The invention relates to a high confined water stratum all-casing all-rotation water stop secant pile and a construction method. Comprising the steps of guide wall construction, plain pile all-casing drilling construction, plain pile hole small-diameter casing drilling and fixing, plain pile pouring and reserved cavity forming, reinforced concrete pile drilling and reinforcement cage mounting, side wall reinforcement inflation core mold manufacturing, side wall reinforcement inflation core mold mounting, reinforced concrete pile pouring and special-shaped water stop cavity forming and framework water stop belt manufacturing. The construction method includes the steps of guide wall construction, plain pile all-casing drilling construction, plain pile hole small-diameter casing drilling and fixing, plain pile pouring and reserved cavity forming, reinforced concrete pile drilling and reinforcement cage mounting, side wall reinforcement inflation core mold mounting, reinforced concrete pile pouring and special-shaped water stop cavity forming and framework water stop belt manufacturing. Mounting a framework water-stop belt, grouting to form a pile, circularly constructing and the like. The framework waterstop is arranged at the joint of the secant piles, the seepage path of a water body is increased through the grouting special-shaped waterstop cavities at the joint of the framework waterstop and the secant piles, the anti-seepage performance of the secant piles is greatly improved, and compared with a traditional two-side high-pressure jet grouting pile construction mode, the construction occupied space on the two sides of the secant piles can be effectively reduced; and the construction period and the building material loss are effectively reduced, and the construction cost is effectively reduced.
本发明涉及一种高承压水地层全套管全回转止水咬合桩及施工方法，包括导墙施工、素桩全套管钻进施工、素桩孔内小直径套管钻进固定、素桩浇筑及预留空腔成型、钢筋混凝土桩钻进及钢筋笼安装、侧壁加筋充气芯模制作、侧壁加筋充气芯模安装、钢筋混凝土桩浇筑及异形止水空腔成型、骨架止水带制作、骨架止水带安装、注浆成桩、循环施工等步骤；在咬合桩交接处设置骨架止水带，骨架止水带及咬合桩交接处注浆异形止水空腔增加了水体的渗流路径，大大增加了咬合桩防渗性能，相比传统两侧高压旋喷桩施工方式，可有效减少咬合桩两侧的施工占地，并有效减少施工周期和建筑材料损耗，有效减少施工造价。
