Construction method of composite stratum landing leg type underground diaphragm wall
The invention discloses a construction method of a composite stratum landing leg type underground diaphragm wall, and relates to the technical field of underground engineering, the construction method comprises the following steps: reinforcing a groove wall; the geology is supplemented and surveyed, a guide wall is constructed, and the position of a socketed pile is positioned on the guide wall surface; performing primary grooving according to the position of the socketed pile to form a first groove body and a second groove body; drilling is conducted on the bottom face of the first groove body and the bottom face of the second groove body, and hole sites used for containing the socketed piles are formed; second-time grooving is conducted between the first groove body and the second groove body, and a containing space used for containing the underground diaphragm wall is formed; cleaning the hole site and the accommodating space for the first time; lowering a reinforcement cage; cleaning the hole for the second time; brushing the wall; and concrete is poured, and a supporting system combining the socketed piles and the underground diaphragm wall is formed. According to the construction method of the composite stratum landing leg type underground diaphragm wall, the problems that a rock-socketed underground diaphragm wall is difficult to construct, long in period, high in cost and large in disturbance to a groove wall are effectively solved.
本申请公开一种复合地层支腿式地下连续墙施工方法，涉及地下工程技术领域，该施工方法包括以下步骤：加固槽壁；补勘地质并施工导墙，在导墙面上定位出嵌岩桩的位置；根据嵌岩桩的位置进行第一次成槽，形成第一槽体和第二槽体；在第一槽体的底面和第二槽体的底面钻进，形成用于容纳嵌岩桩的孔位；在第一槽体和第二槽体之间进行第二次成槽，形成用于容纳地下连续墙的容纳空间；对孔位和容纳空间进行第一次清孔；下放钢筋笼；进行第二次清孔；刷壁；浇筑混凝土，形成嵌岩桩和地下连续墙相结合的支护体系。本说明书所提供的复合地层支腿式地下连续墙施工方法，有效解决了嵌岩式地下连续墙施工困难、周期长、成本高、以及对槽壁扰动较大的问题。
