Bead-strung karst cave pile forming treatment construction method
The invention discloses a bead-strung karst cave pile forming treatment construction method, and belongs to the field of karst cave construction. The bead-strung karst cave pile forming treatment construction method comprises the following steps that 1, exploration is conducted on corresponding positions; 2, drilling is conducted; 3, a high-pressure jet grouting method is adopted; 4, high-specific-gravity stabilizing liquid is used for hole forming and wall protecting; 5, a reinforcement cage is put down; and 6, hole cleaning and pouring are conducted. According to the bead-strung karst cave pile forming treatment construction method, high-pressure jet grouting pile construction is conducted on a large bead-strung karst cave to form a solidified columnar body, the high-specific-gravity stabilizing liquid is adopted for wall protecting in the later hole forming process, and the construction effects that formed holes do not collapse, and the pile forming concrete filling coefficient is controlled to be 1.0-1.1 are achieved.
本发明公开了一种串珠溶洞成桩处理施工方法，属于溶洞施工领域，串珠溶洞成桩处理施工方法包括如下步骤：步骤1：相应位置的勘探；步骤2：进行钻孔；步骤3：高压旋喷法；步骤4：高比重稳定液进行成孔护壁；步骤5：下放钢筋笼；步骤6：清孔灌注。本发明公开的一种串珠溶洞成桩处理施工方法，通过在串珠的大溶洞进行高压旋喷桩桩施工成固结成柱状体，在后期成孔过程中采用高比重稳定液护壁的方式达到成孔不坍塌，成桩砼充盈系数控制在1.0～1.1之间的施工效果。
