Novel sand consolidation anchor rod system and implementation method
The invention relates to a novel sand consolidation anchor rod system and an implementation method, the system comprises a loading plate, a sand column body, a steel circular ring, an anchor rod body, a force transmission pipe, a bearing plate, a drill hole and the like, the implementation method comprises the following steps: firstly, sleeving the force transmission pipe into the anchor rod body, pushing the force transmission pipe into the drill hole, and pushing the steel circular ring to extrude the sand column body by the force transmission pipe, so that the sand column body is crushed and reduced into loose sand; and along with the increase of the thrust, the sand body close to the steel circular ring area is pressed more compactly and is highly combined with the hole wall of the drill hole, friction force can be generated between the sand body and the surface of the hole wall, when the thrust applied by equipment outside the hole reaches 10 KN, it can be judged that an effective sand-gravel seal is formed, and then the force transmission pipe is taken out. The end, with the threads, of the anchor rod body is connected with out-hole tensioning equipment, then drawing force is applied, the hollow sand column body is crushed in sequence and then pressed to be highly compact till the drawing force meets the requirement of engineering design, finally, the locking nut is tightened, and tensioning construction of the sand consolidation anchor rod is completed.
本发明涉及一种新型砂固结锚杆系统及实施方法，该系统包括荷载板、砂柱体、钢圆环、锚杆体、传力管、承压板、钻孔等，该实施方法先将传力管套入锚杆体，并将传力管推入钻孔中，由传力管推动钢圆环挤压砂柱体，使得砂柱体被压碎还原成散砂，并逐渐被压密，随着推力的增大，靠近钢圆环区域的砂体越压越密实，并与钻孔孔壁高度结合，砂体与孔壁表面可产生摩擦力，当孔外设备施加推力达到10KN时，可判定已形成有效的砂石质封口，随后取出传力管，将锚杆体带螺纹一端与孔外张拉设备连接，然后施加拉拔力，空心砂柱体先后被压碎，然后被压成高度致密，直至拉拔力达到工程设计所需，最后拧紧锁紧螺母，完成本次砂固结锚杆张拉施工。
