Construction method for side wall of foundation pit of subway station
The invention relates to the field of metro station foundation pit construction, in particular to a metro station foundation pit side wall construction method which comprises the following steps that S1, a fender post working face is excavated; s2, arranging an opposite-pull screw rod, and enabling the axial direction of the opposite-pull screw rod to be perpendicular to the working face of the fender post; s3, steel bar meshes are laid, specifically, the steel bar meshes are bound on the opposite-pull screws, so that the steel bar meshes form a leveling plane; the split screws are painted and marked at equal intervals by taking the leveling surface as a reference to form marking surfaces; s4, the opposite-pull screws penetrate through the pouring sub-formworks, and the pouring sub-formworks are oppositely pulled and fixed with the painting marks as reference; a supporting assembly is installed on the side, away from the fender post, of the pouring sub-formwork, and the supporting assembly and the bottom of the foundation pit are fixed to support the pouring sub-formwork; s5, the concrete is poured horizontally in a layered mode; and S6, after the strength of the to-be-poured concrete reaches the formwork removal condition, formwork removal is conducted. The surface flatness of the side wall after pouring can be guaranteed.
本发明涉及地铁车站基坑的施工领域，具体涉及一种地铁车站基坑侧墙的施工方法，包括如下步骤：S1、围护桩作业面开挖；S2、布置对拉螺杆，使对拉螺杆的轴向方向垂直于围护桩作业面；S3、敷设钢筋网片，在对拉螺杆上绑扎钢筋网片，使钢筋网片形成找平面；以找平面为基准在各对拉螺杆上等距离刷漆标记形成标记面；S4、使对拉螺杆穿过浇筑子模板，并以刷漆标记为参考对拉固定各浇筑子模板；在浇筑子模板远离围护桩的一侧安装支护组件，并将支护组件与基坑底部固定对浇筑子模板进行支撑；S5、混凝土按水平分层浇筑；S6、待浇筑的混凝土强度达到拆模条件后进行拆模。本发明能够保证侧墙浇筑后的表面平整度。
