Portable power transmission line construction ground anchor and construction method thereof
The invention discloses a portable power transmission line construction ground anchor and a construction method thereof, and relates to the technical field of construction ground anchors, the portable power transmission line construction ground anchor comprises an anchor rod, an expansion sleeve, a pressure boss and a compression nut, the construction ground anchor lifts the anchor rod by screwing the compression nut, and the expansion sleeve expands outwards under the action of a wedge-shaped step of the anchor rod; the friction force is generated by extrusion; under the combined action of the compression nut and the pull rope, the expansion sleeve extrudes the hole wall of the rock to generate friction force equivalent to tensile force, so that the whole ground anchor system achieves stress balance, and effective anchoring of the ground anchor is achieved. The whole device adopts a modular and lightweight design principle, and is convenient to load, unload and transport in complex terrains.
本发明公开一种轻便型输电线路施工地锚及其施工方法，涉及施工地锚技术领域，包括锚杆、膨胀套筒、压力凸台以及压紧螺母，施工地锚通过拧动压紧螺母提升锚杆，膨胀套筒在锚杆的楔形台阶的作用下向外膨胀，直到与孔壁贴合并挤压产生摩擦力；在压紧螺母和拉绳的共同作用下，膨胀套筒挤压岩石孔壁产生与拉力相当的摩擦力，使整个地锚系统达到受力平衡，从而实现地锚的有效锚固。装置整体采用模块化、轻量化设计原则，方便在复杂地形中的装卸与运输。
