Hard rock stratum drilling pile foundation detachable pile casing construction technology and pile casing structure of hard rock stratum drilling pile foundation detachable pile casing construction technology
The invention discloses a hard rock stratum drilling pile foundation detachable pile casing construction technology and a pile casing structure thereof, and relates to the technical field of building engineering.The pile casing structure comprises a first pile casing and a second pile casing, a positioning assembly is arranged on the outer surface of the first pile casing, and a connecting assembly is arranged on the outer surface of the second pile casing; in the construction process of the drilling pile foundation, a second protection cylinder is firstly driven into a hole position, it is ensured that the lower end of the protection cylinder makes contact with the foundation, then one end of a positioning assembly is moved to the position corresponding to a connecting assembly, and therefore a first connecting sleeve coincides with the top view of a circular ring; meanwhile, the multiple conical blocks are rotated to the positions corresponding to the multiple circular grooves, the connecting sleeve continues to move downwards, the inclined blocks are clamped between the sleeve and the conical blocks, the multiple conical blocks are fixed into the multiple circular grooves correspondingly, and therefore connection and sealing between the first pile casing and the second pile casing are achieved; the problems that in the prior art, a pile casing is inconvenient to disassemble, and the difficulty of installing and moving out a long pile casing is increased are solved.
本发明公开了一种硬质岩层钻进桩基可拆式护筒施工工艺及其护筒结构，涉及建筑工程技术领域，包括第一护筒和第二护筒，所述第一护筒的外表面设置定位组件，所述第二护筒的外表面设置连接组件；本发明，通过在钻进桩基施工过程中，首先将第二护筒打入孔位，确保护筒的下端与基础相接触，然后将定位组件的一端移动至与连接组件相对应的位置，从而使得第一连接套与圆环的顶视图重合，同时将多个锥形块旋转至与多个圆槽相对应的位置，继续向下移动连接套，使得斜块卡在套管与锥形块之间，将多个锥形块分别固定在多个圆槽的内部，从而实现了第一护筒与第二护筒之间的连接和密封，解决了现有技术中护筒不方便拆卸增加较长护筒安装和移出的难度的问题。
