Anchoring device and method for geotechnical engineering
The invention belongs to the technical field of geotechnical engineering equipment, and particularly relates to an anchoring device and method for geotechnical engineering. The anchor rod comprises a main screw rod and a first-stage anchoring assembly; the upper end of the primary anchoring assembly is arranged on the outer side wall of the upper portion of the main screw and can only rotate in the circumferential direction of the main screw. The lower end of the primary anchoring assembly is connected to the lower part of the main screw rod and can only move up and down along the main screw rod; an outward expansion retraction mechanism is arranged in the middle of the first-stage anchoring assembly, and the outward expansion retraction mechanism can expand or retract outwards when the lower end of the first-stage anchoring assembly moves up and down along the main screw rod. The distance between the upper end and the lower end of the first-stage anchoring assembly can be conveniently adjusted by rotating the main screw rod, so that the extension retraction mechanism is in close contact with the inner wall of a drill hole, and stable anchoring is achieved.
本发明属于岩土工程设备技术领域，具体地涉及一种用于岩土工程的锚固装置及方法。本发明包括主螺杆和一级锚固组件；一级锚固组件的上端置于主螺杆的上部外侧壁，且只可沿主螺杆的周向转动；一级锚固组件的下端连接在主螺杆的下部且只可沿主螺杆上下移动；一级锚固组件的中部设置有外张回缩机构，外张回缩机构在一级锚固组件的下端沿主螺杆上下移动时可向外张开或回缩。本发明通过旋转主螺杆即可方便调整一级锚固组件上下端之间的距离，从而使外张回缩机构与钻孔内壁紧密接触，实现稳定的锚固。
