Karst cave penetrating pile foundation structure and construction method thereof
The invention belongs to the technical field of building construction, and discloses a karst cave penetrating pile foundation structure and a construction method thereof. The karst cave penetrating pile foundation structure comprises a reinforcement cage and an enclosure device. The reinforcement cage is sleeved with the enclosure device, the enclosure device comprises a pile casing and flaring parts connected to the two ends of the pile casing, and sliding assemblies are arranged at the ends, away from the pile casing, of the flaring parts. By means of the flaring part, in the concrete pouring process, concrete is drained into the pile casing, and the concrete is prevented from flowing into a karst cave. After the concrete flows through the pile casing, the concrete flows into the pile hole below the karst cave, and therefore materials can be saved. And by arranging the sliding assembly, in the process of lowering the reinforcement cage into the pile hole, the sliding assembly is in rolling contact with the inner wall of the pile hole, so that the lowering smoothness of the reinforcement cage can be improved, and the working efficiency is improved. The karst cave penetrating pile foundation is simple in structure and low in installation precision requirement, has a good enclosing effect on concrete, effectively prevents the concrete from flowing into a karst cave, saves materials and can improve the construction quality of the pile foundation.
本发明属于建筑施工技术领域，公开了一种穿溶洞桩基结构及其施工方法。穿溶洞桩基结构包括钢筋笼和围护装置。钢筋笼套设于所述围护装置中，围护装置包括护筒以及连接于护筒两端的扩口部，扩口部远离护筒的一端设置有滑动组件。通过扩口部，在混凝土灌注的过程中，将混凝土引流至护筒中，防止混凝土流入溶洞中。混凝土流经护筒后，再流至溶洞下方的桩孔中，由此能够节约物料。通过设置滑动组件，在将钢筋笼下放至桩孔的过程中，滑动组件与桩孔的内壁滚动接触能提高钢筋笼下放的流畅性，提高作业效率。此穿溶洞桩基结构简单，安装精度要求低，且对混凝土起到较好的围护效果，有效防止混凝土流入溶洞中，节省物料，能提高桩基的施工质量。
