The invention discloses a prestressed rectangular cast-in-situ bored pile, and relates to the technical field of foundation pit engineering construction, the prestressed rectangular cast-in-situ bored pile comprises a load-bearing steel bar, and the outer part of the load-bearing steel bar is equally sleeved with a plurality of groups of first sliding anchoring frames and a plurality of groups of second sliding anchoring frames; and two sets of rectangular reinforcing stirrups are installed in the multiple sets of first sliding anchoring frames and the multiple sets of second sliding anchoring frames, and multiple sets of prestress dynamic feedback adjusting assemblies are installed in gaps between the two sets of rectangular reinforcing stirrups. The prestress can be automatically adjusted according to the actual load condition so as to cope with the stress change of the overall structure, the overall stability and durability of the structure can be enhanced, the overall operation performance can be effectively improved, the prestress can be accurately controlled and flexibly adjusted before and after construction, and then the adaptability and reliability of the overall structure can be improved.
本发明公开了一种预应力矩形钻孔灌注桩，涉及基坑工程施工技术领域，包括受力钢筋，受力钢筋的外部分别等分套设安装有多组第一滑动锚固架和多组第二滑动锚固架，多组第一滑动锚固架和第二滑动锚固架的内部安装设置两组矩形加强箍筋，两组矩形加强箍筋的间隙处安装设置有多组预应力动态反馈调节组件，通过在预应力动态反馈调节组件和预应力微调组件配合下，使得能够根据实际负载情况自动调节预应力，以应对整体结构应力的变化，增强结构的整体稳定性和耐久性，有效提高整体作业性能，并使得在施工前及施工后，能够对预应力进行精确控制和灵活调整，进而提高整体结构的适应性和可靠性。
