Cast-in-place concrete pile rotary excavating assembly and long pile casing construction method based on cast-in-place concrete pile rotary excavating assembly
The invention relates to the technical field of civil engineering, in particular to a cast-in-place concrete pile rotary excavating assembly and a long pile casing construction method based on the cast-in-place concrete pile rotary excavating assembly. The cast-in-place concrete pile rotary excavating assembly comprises an assembly body, and the assembly body comprises a drill bit; a cavity is formed in the drill bit, and a first through hole is formed in the outer side wall of the drill bit. A rotating block is arranged in the cavity, and a plurality of first sub-drill bits are arranged on the side wall, close to one end of the first through hole, of the rotating block; and a pushing mechanism is also arranged in the cavity. The long pile casing construction method based on the cast-in-place concrete pile rotary excavating assembly comprises the steps that a mounting hole is excavated; a pile casing is put down; pile holes are excavated; grouting for the first time; the pile casing is dismantled; grouting for the second time; the concrete is prevented from exceeding the square, and the cost of a project department is saved.
本发明涉及土木工程技术领域，具体地说，涉及混凝土灌注桩旋挖组件及基于此的长护筒施工方法。混凝土灌注桩旋挖组件包括组件主体，组件主体包括钻头；钻头内部设有空腔，钻头外侧壁处设有第一通孔；空腔内设有转动块，转动块靠近第一通孔一端的侧壁处，设有多个第一子钻头；空腔内还设有推动机构。基于混凝土灌注桩旋挖组件的长护筒施工方法，包括开挖安装孔；下护筒；开挖桩孔；第一次注浆；拆除护筒；第二次注浆；防止了混凝土超方情况，节省了项目部的成本。
