Pre-fractured drilling pile head removing construction method
The invention relates to a pre-fractured drilling pile head removing construction method. A pile head is included, and a steel reinforcement cage is arranged on the pile head. The pre-fractured drilling pile head removing construction method includes the steps that (1), the outer side of the steel reinforcement cage is fixedly connected with a ring expansion box in the circumference direction; (2), concrete pouring is finished and reaches a final set state; (3), the ring expansion box expands, the volume increases, and contact pressure is generated on the upper surface and the lower surface ofthe expansion box; and (4) the pile head and a pile body break under the action of the expansion box. In the construction of a pile foundation, the ring expansion box is installed on the outer side of the steel reinforcement cage on the pile head in the circumference direction, the expansion of the expansion box enables the pile head to break to achieve the purpose of breaking the pile head, theoperation is convenient, the construction period is short, and the risk index is reduced.
本发明涉及一种预断裂钻孔桩桩头去除施工工法，包括桩头，桩头部分设有钢筋笼，步骤如下：1）钢筋笼外侧环向固定连接环形膨胀盒；2）混凝土浇筑完成达到终凝状态；3）环形膨胀盒膨胀，体积增大，使膨胀盒上下表面产生接触压力；4）桩头与桩身在膨胀盒的膨胀作用下发生断裂。桩基施工中桩头部位钢筋笼外侧环向安装环形膨胀盒，膨胀盒膨胀使桩头断裂，达到破除桩头目的，操作方便，工期短，降低风险指数。
