Fabricated foundation pit pile wall composite enclosure structure and construction method thereof
The invention discloses an assembly type foundation pit pile wall composite enclosure structure and a construction method thereof, the assembly type foundation pit pile wall composite enclosure structure comprises precast piles, precast shear wallboards and anchor rods, and the construction technological process of the assembly type foundation pit pile wall composite enclosure structure comprises the steps of a, piling the precast piles, b, excavating earthwork in a layered mode, c, installing triangular supporting steel frames on pile bodies, d, installing channel steel joists, e, hoisting the precast shear wallboards, f, installing temporary fixing plates, g, grouting and h, piling the anchor rods. The construction method comprises the following steps: i, dismantling a temporary fixing plate, j, supplementing slurry and leveling a structural surface, k, dismantling a triangular support steel frame and a channel steel joist, l, sequentially repeating the steps b to k until the hoisting of the whole structure is completed, m, carrying out waterproof construction, and n, carrying out acceptance check. The triangular supporting steel frames and the channel steel joists are effectively arranged, the hoisting elevation positioning and supporting bearing effects are achieved, layer-by-layer and section-by-section hoisting supporting is achieved, mounting and dismounting are convenient, hoisting errors are easy to adjust, the overall structural design is reasonable, the fabricated construction efficiency is high, safety and reliability are achieved, the hoisting speed is high, and a new technical method is provided for fabricated foundation pit construction in China.
本发明公开了一种装配式基坑桩墙复合围护结构及其施工方法，包括预制桩、预制剪力墙板、锚杆组成，其施工工艺流程为：a.打设预制桩，b.分层开挖土方，c.桩身安装三角支撑钢架，d.安装槽型钢托梁，e.吊装预制剪力墙板，f.安装临时固定板，g.注浆，h.打设锚杆，i.拆除临时固定板，j.补浆，结构面找平，k.拆除三角支撑钢架和槽型钢托梁，l.依次重复步骤b至步骤k，直至完成整体结构吊装，m.防水施工，n.验收。本发明有效设置三角支撑钢架和槽型钢托梁，起到吊装标高定位和支撑承载作用，实现了逐层、逐段吊装支撑，安拆方便，吊装误差易调，整体结构设计合理，装配化施工效率高，安全可靠，吊装速度快，为我国装配式基坑施工提供了新的技术方法。
