Hole collapse prevention construction method of bit expanded anchor cable
The invention relates to a hole collapse prevention construction method of a bit expanded anchor cable. The method comprises the following steps that S1, a slope body is reinforced; S2, an anchor roddrilling machine is in place and aligned with hole sites, the angle is adjusted, and machine legs are stably located; S3, a casing protection wall of the drilling machine conducts drilling to the designed depth, and the position for an expanded bit is reserved; S4, a spraying pipe is put in; S5, cement grout is prepared, a high-pressure pump is started to reach the designed pressure, the bit expanded anchor rod drilling machine is started to rotate, and spraying irrigation is conducted in an up-down moving mode for high-pressure spraying reaming; S6, after reaming is completed, an anchor cableassembly is placed into the casing protection wall of the drilling machine to the designed depth, and a grouting pipe is put in along with the anchor cable assembly; S7, the casing protection wall ofthe drilling machine is pulled out; S8, grouting is conducted; and S9, tensioning locking is conducted. The method has the effect of preventing the hole collapse phenomenon of the whole anchor cableassembly hole.
本申请涉及一种扩大头锚索预防塌孔施工方法，其包括以下步骤：S1：坡体加固；S2：锚杆钻机就位，对准孔位，调整好角度，机脚座落稳定；S3：钻机的套管护壁钻孔至设计深度，并预留扩大头位置；S4：放入喷管；S5：配置好水泥浆液，开动高压泵至设计压力，开动扩大头锚杆钻机旋转，并上下移动喷灌进行高压喷射扩孔；S6：扩孔完毕后，从钻机的套管护壁中放入锚索组件至设计深度，注浆管随锚索组件放入；S7：拔出钻机的套管护壁；S8：注浆；S9：张拉锁定。本申请具有预防整个锚索组件孔洞塌孔现象发生的效果。
