Foundation tubular pile for sandbar foundation pit and basement foundation pit construction method
The invention relates to a foundation tubular pile for a sandbar foundation pit and a basement foundation pit construction method. The pipe pile comprises a pipe pile body, a plurality of horn-shaped gear rings are arranged on the pipe pile body in the height direction of the pipe pile at intervals, vertical holes are formed in the gear rings in the annular direction of the pipe pile body at intervals, the vertical holes penetrate through the gear rings in the vertical direction, and inclined holes are formed in the positions, between the adjacent gear rings, of the pipe pile body; the two ends of each inclined hole extend and penetrate through the side wall of the pipe pile body, the ends, close to the center of the pipe pile body, of the inclined holes are obliquely arranged from low to high from the ends, away from the center of the pipe pile body, the other ends of the inclined holes are expanded outwards to form expanded hole parts, the expanded hole parts are filled with drainage filler, and inverted filter cloth is wound around the pipe pile body relative to the peripheries of the inclined holes. The gear ring is additionally arranged on the pipe pile, so that the pipe pile is driven more easily; meanwhile, due to the design of the inverted filter layers between the gear rings, the inverted filter layers are not prone to being scratched when the pipe pile is driven in, the meshing force with sandy soil can be increased in the later period, and the anti-floating capacity of the pipe pile is enhanced.
本发明涉及一种沙洲基坑用地基管桩及地下室基坑施工方法。上述管桩包括管桩本体，管桩本体上沿管桩高度方向间隔设有多个喇叭状齿圈，齿圈上沿管桩本体的环向方向间隔开设有竖向孔，竖向孔沿竖直方向贯穿齿圈，且管桩本体上于相邻齿圈之间开设有斜孔，斜孔的两端延伸并贯穿管桩本体侧壁，且斜孔靠近管桩本体中心处的一端至远离管桩本体中心处的另一端呈由低到高的倾斜设置，斜孔的另一端向外扩孔形成扩孔部，扩孔部内填塞有排水填料，管桩本体上相对斜孔外围缠绕有反滤布。在管桩上增加齿圈，使打入管桩更加容易；同时，齿圈间的反滤层设计也使管桩打入时反滤层不易被刮坏，后期可增加与沙土的咬合力，以增强管桩的抗浮能力。
