Pile casing device for foundation pit fender pile construction
The invention discloses a pile casing device for foundation pit fender pile construction, and belongs to the field of building construction. A pile casing device for foundation pit fender pile construction comprises a pile casing body, a containing groove is formed in the side wall of the pile casing body, the lower portion of the containing groove penetrates through the external space, and two sets of expansion blocks are arranged in the containing groove; a connecting rod is hinged to the face, facing the axis of the pile casing body, of each expansion block, a vertical frame is hinged to the end of each connecting rod, a first circular ring is connected to the top of the vertical frame of the group of expansion blocks connected to the lower portion, and a second circular ring is connected to the top of the vertical frame of the group of expansion blocks connected to the upper portion. The first circular ring moves downwards before the second circular ring, and when the first circular ring and the second circular ring move downwards to the lowest position, the two groups of expansion blocks form a convex ring exceeding the outer wall of the pile casing body and are embedded into the inner wall of a pile hole; by arranging the two groups of expansion blocks, the mounting and fixing effect on the pile casing body is enhanced, so that the pile casing is suitable for fixing the pile casing body in stratums in different states.
本发明公开了一种基坑围护桩施工护筒装置，属于建筑施工领域；一种基坑围护桩施工护筒装置，包括护筒本体，护筒本体的侧壁内开设有容纳槽，容纳槽的下部贯通外部空间，容纳槽内设置有两组扩张块；每个扩张块上朝向护筒本体轴线的面上均铰接有连杆，连杆的端部铰接有竖直架，连接于下部的一组扩张块的竖直架的顶部连接有第一圆环，连接于上部的一组扩张块的竖直架的顶部连接有第二圆环；第一圆环先于第二圆环下移，且第一圆环和第二圆环均下移至形成最低处时，两组扩张块组成一超出护筒本体外壁的凸环并嵌入桩孔的内壁；本发明通过设置两组扩张块增强对护筒本体的安装固定效果，从而适应不同状态地层时对护筒本体的固定。
