Construction method of modular soil nailing wall support
The invention discloses a construction method of a modularized soil nailing wall support. Comprising the following steps: S1, manufacturing soil nails; s2, a reinforcing mesh is bound at one end of each soil nail in the direction perpendicular to the soil nail; s3, a formwork is erected, and a soil nailing wall face layer concrete module is poured; s4, a top concrete plate is manufactured; s5, the top concrete plate of the soil nailing wall extends out of the foundation pit, and the fixing steel bars of the horizontal part are nailed into the edge of the foundation pit to be fixed; s6, foundation pit earthwork is excavated, soil nail holes are drilled, a soil nail wall surface layer concrete module is laid on the slope surface, soil nails are inserted into the soil nail holes, and concrete convex plates are placed on the four sides of a concrete concave plate; s7, grouting the grouting openings of the concrete convex plate and the concrete concave plate; and S8, after the grouting concrete in the soil nailing holes is cured to reach certain strength, soil nailing wall supporting construction can be completed. According to the construction method, the construction speed is increased, the problem that sprayed concrete pollutes the environment is solved, the construction process is simple and easy to operate, the labor intensity is reduced, and the working efficiency is improved.
本发明公开了一种模块化土钉墙支护的施工方法。包括如下步骤：S1、土钉制作；S2、在土钉的一端且垂直于土钉方向绑扎钢筋网；S3、支设模板并浇筑土钉墙面层混凝土模块；S4、制作顶部混凝土板；S5、土钉墙顶部混凝土板向基坑外延伸，水平部的固定钢筋钉入基坑边进行固定；S6、基坑土方开挖、钻设土钉孔，坡面铺设土钉墙面层混凝土模块，土钉插入土钉孔内，混凝土凹板四面摆放混凝土凸板；S7、混凝土凸板和混凝土凹板的注浆口内注浆；S8、待土钉孔内的注浆混凝土养护达到一定强度后，即可完成土钉墙支护施工。本施工方法加快了施工速度，解决了喷射混凝土污染环境的问题，施工工艺简单易操作，降低劳动强度，提高了工作效率。
