Foundation pit supporting soil nailing wall supporting construction method
The invention relates to the technical field of building construction, in particular to a foundation pit supporting soil nailing wall supporting construction method which comprises the steps that the side wall of a foundation pit is leveled, lineation is conducted on the side wall of the foundation pit, a plurality of auxiliary wing plates are welded to the side face of the tip end of a grouting soil nail, the multiple auxiliary wing plates are arranged in a circumferential array mode, and the grouting soil nail is nailed into the side wall of the foundation pit. The grouting soil nails are rotated in the nailing process, so that the grouting soil nails rotate around the center axis, grouting is conducted on center rods of the grouting soil nails through grouting equipment, a concrete surface layer is sprayed to the side wall of the foundation pit, after the surface layer is solidified, a reinforcing mesh is laid on the surface layer, tie bars are installed, and the grouting soil nails on the side wall of the foundation pit are connected in series through transverse and longitudinal tie bars and are welded and fixed. And the tie bars and the reinforcing mesh are welded and fixed, and the concrete surface layer is sprayed multiple times till the preset thickness is achieved. When the grouting soil nail is constructed, a rotating circumferential force is provided for the grouting soil nail, the wing plate is assisted to rotationally cut a soil layer, the normal mounting resistance of the grouting soil nail on the side wall of a foundation pit is reduced, the grouting soil nail can be nailed in conveniently, and mounting errors are reduced.
本申请涉及建筑施工的技术领域，具体是一种基坑支护土钉墙支护施工方法，包括平整基坑侧壁，在基坑侧壁划线，在注浆土钉尖端侧面焊接多个辅助翼板，多个辅助翼板圆周阵列排布，将注浆土钉钉入基坑侧壁，并在钉入过程中转动注浆土钉，使注浆土钉沿中心轴自转，通过注浆设备向注浆土钉中心杆注浆，在基坑侧壁喷射混凝土面层，面层凝固后在上方铺设钢筋网，安装拉筋，通过横纵拉筋串联基坑侧壁上的注浆土钉并焊接固定，拉筋与钢筋网焊接固定，多次喷射混凝土面层，直至达到预定厚度。本申请在注浆土钉施工时，为注浆土钉提供一个旋转的周向力，辅助翼板旋转切割土层，减少了注浆土钉在基坑侧壁法向的安装阻力，便于注浆土钉钉入，减少安装误差。
