Construction method and system for enlarged foundation cast-in-place pile
The invention discloses an expanded foundation cast-in-place pile construction method and system.The method comprises the steps that drilling equipment is used for drilling a foundation, and drilling is stopped after the designated depth is reached; after a hole is formed in the foundation, a high-pressure water pipe is bound to the outer side of the reinforcement cage, and after the reinforcement cage descends to the designated depth, the reinforcement cage stops moving; the steel reinforcement cage is moved up and down and rotated through the hoisting equipment, under the control of the controller, high-pressure water with water pressure is provided according to the material of the foundation with the specified depth, the high-pressure water washes the foundation around the specified depth, and washing is stopped after washing completion data is received; an enlarged foundation position is formed; and after the concrete is solidified, the reinforcement cage and the enlarged foundation position at the bottom of the reinforcement cage jointly form the enlarged foundation cast-in-place pile. The system comprises a cast-in-place pile, a reinforcement cage 2, a high-pressure water pipe, an enlarged foundation pile, a controller and a water pump. The foundation position is enlarged at a certain depth, the bearing area of the pile end can be increased, and therefore the bearing capacity of the pile is improved.
本发明公开了一种扩大基础灌注桩施工方法及系统，方法包括使用钻孔设备对地基进行开孔，等达到指定深度后，停止钻孔；地基开孔后，在钢筋笼外侧绑定高压水管，等钢筋笼下到指定深度后，钢筋笼停止移动；通过吊装设备上下移动及旋转钢筋笼，在控制器的控制下，根据指定深度地基的材质提供带有水压的高压水，高压水冲刷指定深度周边的地基，接收到冲刷完成的数据后，停止冲刷；即形成一个扩大基础位置；灌注混凝土，待混凝土凝固后，钢筋笼及其底部的扩大基础位置共同形成扩大基础灌注桩。系统包括灌注桩、钢筋笼2、高压水管、扩大基础桩、控制器、水泵。本发明在一定深度扩大基础位置，可以增加桩端的承载面积，从而提高桩的承载力。
