Tension-compression composite anchor rod and construction method thereof
The invention discloses a tension-compression composite anchor rod and a construction method thereof, and relates to the technical field of rock-soil anchoring engineering.The tension-compression composite anchor rod structurally comprises an anchor rod body, the anchor rod body comprises a plurality of steel strands which are symmetrically arranged, extrusion sleeves are fixedly installed on the steel strands, the steel strands are arranged on a bearing plate in a penetrating mode, and the extrusion sleeves are fixedly installed on the bearing plate. The pressure bearing plate is fixedly connected with the extrusion sleeve; the steel strand is sleeved with a sleeve, and one end of the sleeve abuts against the bearing plate. The steel strand is fixedly connected with a ship-shaped centering support through a buckle. Grouting pipes are arranged on the outer sides of the steel strands and comprise the primary grouting pipe and the secondary grouting pipe. According to the construction method of the tension-compression composite anchor rod based on the structure, it can be guaranteed that the rod body of the tension-compression composite anchor rod is centered in the drill hole, the rod body can be conveniently and rapidly put into the drill hole, convenient and rapid lateral installation of the rod body on the ship-shaped centering support can be achieved, the construction process is greatly simplified, and the bearing capacity can be improved.
本发明公开一种拉压复合型锚杆及其施工方法，涉及岩土锚固工程技术领域，其结构包括锚杆本体，所述锚杆本体包括对称设置的多个钢绞线，所述钢绞线上固定安装有挤压套，多个所述钢绞线穿设于承压板上，所述承压板与所述挤压套固定连接；所述钢绞线上套设有套管，所述套管一端与所述承压板抵接；所述钢绞线通过卡扣固定连接有船型对中支架；所述钢绞线外侧设有注浆管，所述注浆管包括一次注浆管和二次注浆管。本发明基于上述结构的拉压复合型锚杆施工方法，能保证拉压复合型锚杆杆体在钻孔中居中，方便杆体快速下放入钻孔中，能实现杆体在船型对中支架上的便捷化侧向安装，不仅大大简化施工流程，而且可以提高承载力。
