Construction method of manual hole digging pile and manual hole digging pile
The invention provides a construction method of a manual hole digging pile and the manual hole digging pile. The construction method comprises the steps of digging a pile hole section; installing a reinforcing mesh: the reinforcing mesh is installed along the inner wall of the pile hole section, a plurality of first reinforcing bar sections extending upwards are arranged at the upper end of the reinforcing mesh, and a plurality of second reinforcing bar sections extending downwards are arranged at the lower end of the reinforcing mesh; welding the reinforcing meshes of two adjacent pile hole sections: the first reinforcing mesh sections of the reinforcing mesh in the pile hole section are welded with second reinforcing mesh sections of a reinforcing mesh in an adjacent previous pile hole section; installing a pile casing: the pile casing is installed in the pile hole section, a concrete pouring area is formed between the pile casing and the inner wall of the pile hole section, and thereinforcing mesh is located in the concrete pouring area; pouring concrete: the concrete is poured into the concrete pouring area to form a reinforced concrete retaining wall; and excavating a next pile hole section: the pile casing is detached, and the next pile hole section is evacuated. By means of the construction method, the stability of connection between retaining walls of every two adjacent pile hole sections can be effectively improved.
本申请提供一种人工挖孔桩的施工方法以及人工挖孔桩，该施工方法包括开挖一段桩孔段；安装钢筋网：沿桩孔段的内壁安装钢筋网，钢筋网的上端设置有多个向上延伸的第一钢筋段，钢筋网的下端设置有多个向下延伸的第二钢筋段；焊接相邻两个桩孔段的钢筋网：焊接桩孔段内的钢筋网的第一钢筋段与相邻的上一段桩孔段内的钢筋网的第二钢筋段；安装护筒：将护筒安装在桩孔段内，护筒与桩孔段的内壁之间形成混凝土灌注区域，钢筋网位于混凝土灌注区域内；灌注混凝土：向混凝土灌注区域内灌注混凝土以形成钢筋混凝土护壁；开挖下一段桩孔段：拆除护筒，开挖下一段桩孔段。该施工方法可有效提高相邻两段桩孔段的护壁之间连接的稳固性。
