Anchor rod static pressure steel pipe pile and construction method thereof
The invention discloses an anchor rod static pressure steel pipe pile and a construction method. A pile body comprises an anchor rod reaction frame, a jack and a steel pipe pile. Stirring shafts and stirring blades are arranged at the bottoms of the steel pipe piles; water wheels are arranged at the upper ends of the stirring shafts; the water pressure output equipment of the steel pipe pile comprises a high-pressure water pipe, the lower portion of the high-pressure water pipe communicates with an elbow, and the elbow is provided with a nozzle used for pushing a water wheel; the water pressure output equipment further comprises a bracket, cantilevers of the bracket correspond to the elbows, and each cantilever is arranged above the corresponding elbow in a covering mode. A convex ring for clamping the cantilever end of the cantilever to limit the lower limit of the water pressure output equipment is welded on the inner wall of the steel pipe pile; l-shaped clamping plates in one-to-one correspondence with the cantilevers are welded to the inner wall of the steel pipe pile. The construction method comprises the steps that during pile pressing, the water delivery pump is started synchronously to spray high-pressure water columns to drive the stirring shaft, pile bottom soil is loosened, and the bracket is automatically clamped with the L-shaped clamping plate on the inner wall of the steel pipe pile under the counter force of high-pressure water flow. According to the steel pipe pile and the construction method, torque is sufficient and stable, pile sinking resistance can be reduced, and the power input device is convenient to disassemble and assemble.
本发明公开一种锚杆静压钢管桩和施工方法，桩体包括锚杆反力架、千斤顶和钢管桩；钢管桩底部设有搅拌轴及搅拌叶片；搅拌轴上端设水轮；该钢管桩的水压输出设备包括高压水管，高压水管下部连通有弯头，弯头设有用于推动水轮的喷口；水压输出设备还包括托架，托架的悬臂与弯头对应且每个悬臂罩在对应弯头上方；钢管桩内壁焊接有用于卡住悬臂悬挑端以限定水压输出设备下限的凸环；钢管桩内壁焊接有与悬臂一一对应的L形卡板；该施工方法为，压桩时同步启动输水泵喷射高压水柱驱动搅拌轴，扰松桩底土体，且托架在高压水流反力下与钢管桩内壁的L形卡板自动卡接。该钢管桩和施工方法扭矩充足稳定，能降低沉桩阻力，且动力输入装置拆装方便。
