Full casing follow-up construction method of rotary drilling rig
The invention discloses a full casing follow-up construction method of a rotary drilling rig. The full casing follow-up construction method includes the following steps that: setting out and positioning of a pile position are conducted; the rotary drilling rig is used for drilling the pile position for 1m; a bottom section casing is installed; drilling the pile position is conducted for 3m; a standard section casing and the bottom section casing are installed successively; a reinforcement cage is made and installed in a lifting manner, a guide pipe is connected, and the guide pipe is lowered into a drilling hole; pouring concrete is carried out; and the standard section casing and the bottom section casing are pulled out. According to the follow-up construction method, connection and disassembly of the casings is fast and convenient, the pipe cannot be blocked by concrete, the reinforcement cage is not prone to be deformed during pulling out the casings, and upward floating of the reinforcement cage is prevented in the process of pouring the concrete.
本发明公开了一种旋挖钻机全护筒跟进施工方法，包括：对桩位进行放线定位；使用旋挖钻机对桩位钻进1m；安装底节护筒；对桩位继续钻进3m；依次安装标准节护筒、底节护筒；制作、吊放安装钢筋笼，连接导管并向钻孔中下放导管；浇筑混凝土；拔除标准节护筒与底节护筒。本发明所述方法护筒的连接、拆卸快速便捷，混凝土不堵管，在护筒拔除的过程中钢筋笼不易变形，并且在浇筑混凝土的过程中防止钢筋笼向上浮动。
