The invention relates to a recyclable assembly type cement paste sand anchor rod and an anchoring method thereof, and relates to the technical field of geotechnical engineering. The recyclable assembly type cement paste sand anchor rod comprises an anchor rod body; and a load plate, a hollow sand column body and a sealing plate are sequentially arranged on the anchor rod body in the axis directionof the anchor rod body, cement paste is adsorbed to the hollow sand column body, and the load plate is detachably connected with the anchor rod body. After the anchor rod body provided with the loadplate, the hollow sand column body and the sealing plate is installed in an anchor hole, pressure is applied to the sealing plate so that the hollow sand column body can be crushed into gravel. Afterthe anchor rod body is pulled out to compact and consolidate the gravel, the compacted and consolidated gravel can be solidified stably, and the situation that the gravel moves due to the dynamic loadof a site, and consequently anchoring force (prestress) is loosened is relieved. When the anchor rod body needs to be recycled, the anchor rod body can be detached from the load plate and recycled.
本申请涉及一种可回收装配式水泥浆砂锚杆及其锚固方法，涉及岩土工程的技术领域。可回收装配式水泥浆砂锚杆包括锚杆体，锚杆体上沿其轴线方向依次设置有荷载板、空心砂柱体和封板，空心砂柱体吸附有水泥浆，荷载板与锚杆体之间可拆卸连接。将安装好荷载板、空心砂柱体和封板的锚杆体安装进入锚孔后，对封板施压以将空心砂柱体压碎成砂砾。拉拔锚杆体压密固结砂砾后，能对压密固结后的砂砾固化稳定，减缓场地动荷载引发砂砾移动导致锚固力（预应力）松弛。需要回收时，可将锚杆体从荷载板中拆除回收。
