High-recovery-rate recoverable pre-stressed anchor cable support construction method
The invention discloses a high-recovery-rate recoverable pre-stressed anchor cable support construction method, and relates to the technical field of foundation pit support. The problem that building materials such as reinforcing steel bars are wasted due to the fact that anchor cables cannot be recycled in the foundation pit supporting process is solved. The method comprises the steps that the supporting connecting rod is fixed to the guide mechanism, the fixing and limiting mechanism is arranged on the supporting connecting rod, and meanwhile the steel strand is fixed to the guide mechanism. The device is fixed in a drill hole of a foundation pit through the guide cylinder and the fixed connecting rod, the device can be recycled conveniently while the foundation pit can be effectively supported, and the anchor head drives the device to go deep into the drill hole of the foundation pit to extrude the supporting connecting rod so that the supporting connecting rod can push the fixed connecting rod to move in the guide cylinder; due to the fact that the positioning fixing rod can only move transversely under the limitation of the limiting connecting hole, the fixing bearing block moves downwards to enable the rotating connecting plate to rotate, then the positioning fixing rod and the positioning supporting block protrude outwards, and the positioning fixing rod is fixed to the rock soil layer of the foundation pit.
本发明公开了一种高回收率的可回收预应力锚索支护施工方法，涉及基坑围护技术领域；为了解决基坑支护过程中锚索不能回收，造成钢筋等建筑材料浪费的问题；该方法包括将支撑连杆固定在导向机构上，并将固定限位机构安置在支撑连杆上，同时对导向机构进行钢绞线固定。本发明通过导向筒、固定连杆将装置固定在基坑的钻孔中，可以对基坑进行有效的支护同时方便回收装置，锚头带着装置深入基坑的钻孔内部，挤压支撑连杆使得支撑连杆推动固定连杆在导向筒内部移动，由于定位固定杆在限位连孔的限制下只能横向移动，固定承载块下移使得旋转连板旋转，进而将定位固定杆、定位支撑块向外突出，从而将定位固定杆固定在基坑的岩石土层。
