Steel casing for repairing large-diameter pile hole
The invention discloses a steel casing for repairing a large-diameter pile hole, and relates to the technical field of pile foundation construction, the steel casing comprises a center rod and a plurality of coamings, the coamings are distributed in the circumferential direction of the center rod, and the center rod is provided with a telescopic mechanism used for driving the coamings to move in the direction close to or away from the center rod at the same time; when the interior of the pile hole collapses, the center rod is inserted into the collapsed pile hole, all the surrounding plates are located at the collapsed positions in the pile hole, all the surrounding plates are driven to be away from one another through the telescopic mechanism, the collapsed pile hole is opened, and then the effect of rapidly repairing the collapsed pile hole is achieved.
本申请公开了一种大直径桩孔修补用钢护筒，涉及桩基施工的技术领域，其包括中心杆和多个围板，各所述围板沿中心杆的周向分布，所述中心杆上设置有用于驱使各所述围板同时沿靠近或远离中心杆方向移动的伸缩机构；当桩孔内部发生坍塌时，将中心杆插入坍塌的桩孔内，并使各围板位于桩孔内的坍塌位置，通过伸缩机构驱使各围板相互远离，并将坍塌的桩孔撑开，进而达到对坍塌的桩孔快速修补的效果。
