Prestressed foundation pit support cast-in-situ bored pile and construction method thereof
The invention belongs to the technical field of building equipment, and discloses a prestressed foundation pit support cast-in-situ bored pile which comprises a first supporting plate, a second supporting plate and a third supporting plate, and eight supporting assemblies are annularly and fixedly connected to the inner walls of the first supporting plate, the second supporting plate and the third supporting plate in a sleeving mode at equal angles. Four fixing assemblies are annularly hinged to the outer side wall of the second supporting plate at equal angles, the lower ends of the inner side walls of the four fixing assemblies are all hinged to the interiors of the supporting assemblies, and four stabilizing assemblies are annularly hinged to the top of the second supporting plate at equal angles. Through cooperation of structures such as the stabilizing assembly and the moving plate, the upper end of the stabilizing plate moves outwards to make contact with the inner wall of the hole and is gradually inserted into the inner wall of the hole, at the moment, the four faces of the reinforcement cage extend outwards through cooperation of the structures, and then the stress area of the upper end of the device and the inner wall of the hole is increased.
本发明属于建筑设备技术领域，且公开了一种预应力基坑围护钻孔灌注桩，包括第一支撑板、第二支撑板和第三支撑板，所述第一支撑板、第二支撑板、第三支撑板的内壁环形等角度固定套接有八个支撑组件，所述第二支撑板的外侧壁环形等角度铰接有四个固定组件，四个所述固定组件内侧壁的下端均与支撑组件的内部铰接，所述第二支撑板的顶部环形等角度铰接有四个稳定组件。本发明通过设置稳定组件和移动板等结构的配合，稳定板上端的向外活动将会与孔洞的内壁相接触，并逐渐插入至孔洞的内壁，这时将会使得钢筋笼的四面通过结构的配合向外延伸，进而提升了该装置上端与孔洞内壁的受力面积。
