Method for constructing anchor cable in landslide body with crack
The invention discloses a method for constructing an anchor cable in a landslide body with a crack. The method comprises the following steps that a slope toe anti-slide pile is constructed at the slope toe of the landslide body to reinforce the landslide body; fine sand is backfilled into an opening section from the ground surface of the landslide body till the opening section is filled, and thenan opening of the crack is filled and tamped with yellow clay; a plurality of plugging grouting holes are formed in the middle and the periphery of the landslide body to the crack section, rubber pipes are inserted into the plugging grouting holes, dry river sand is blown into the crack section through the rubber pipes, the crack section is sequentially filled from the low position to the high position till the crack section is filled, and then grouting is conducted in the crack section through a grouting pipe; and after grouting is completed, drilling can be conducted in the landslide body through solidification, and then construction of the anchor cable is completed. According to the method, the crack is plugged through the sand blowing backfilling grouting technology, and the problems of drill jamming, hole collapse and the like are effectively solved; and meanwhile, a conical impact drill bit is adopted for drilling, drilling is facilitated, the hole position does not deviate, andthe problems of hole deviation, drill jamming and the like can be avoided.
本发明公开了一种在具有裂缝的滑坡体内施工锚索的方法，包括以下步骤：在滑坡体坡脚处施工坡脚抗滑桩对滑坡体进行加固；从滑坡体地表向开口段内回填细沙至开口段填满，然后用黄黏土填满夯实裂缝的开口；在滑坡体中部及周边打设若干个封堵注浆至裂隙段处，在封堵注浆孔内插入胶管，通过胶管向裂隙段内吹干燥的河砂，从低处向高处依次填充裂隙段至裂隙段填满，然后通过注浆管向裂隙段内注浆；注浆全部结束后，经过固结即可在滑坡体内进行钻孔，进而完成锚索的施工。本发明通过吹砂回填注浆技术对裂缝进行封堵，有效解决卡钻塌孔等问题；同时通过采用锥形冲击钻头进行钻孔，有利于钻进，确保孔位不偏移，能够避免偏孔卡钻等问题。
