High-pressure jet grouting anchor rod suitable for backfill soil and grouting method
The invention discloses a high-pressure jet grouting anchor rod suitable for backfill soil and a grouting method, and relates to the field of anchor rods. The high-pressure jet grouting anchor rod suitable for backfill soil comprises an anchor rod, a grouting pipe and a high-pressure jet grouting drill pipe, wherein the grouting pipe is parallel to the anchor rod and is connected with the anchor rod, the high-pressure jet grouting drill pipe sleeves the anchor rod and the grouting pipe, one end of the anchor rod is sequentially connected with a blocking disc and a drill bit, the end of the grouting pipe abuts against the side wall of the blocking disc, and a side nozzle is arranged on the end, close to the blocking disc, of the high-pressure jet grouting drill pipe. The embodiment of the invention further provides a grouting method using the high-pressure jet grouting anchor rod suitable for backfill soil. According to the high-pressure jet grouting anchor rod suitable for backfill soil and the grouting method, the effects of anchor rod positioning and surrounding hole forming can be achieved at the same time, soil is improved and the anchor rod is reinforced by grouting for two times, and slope loosening and separation can be effectively prevented and controlled.
一种适用于回填土的高压旋喷锚杆及注浆方法，涉及锚杆领域。该适用于回填土的高压旋喷锚杆包括锚杆、与锚杆平行布置且相互连接的注浆管及套设于锚杆和注浆管上的高压旋喷钻管，锚杆的一端依次连接有阻隔圆盘和钻头，注浆管的端部抵压阻隔圆盘的侧壁，高压旋喷钻管靠近阻隔圆盘的一端设有侧部喷口。本实施例还提供了使用适用于回填土的高压旋喷锚杆的注浆方法。本实施例提供的适用于回填土的高压旋喷锚杆及注浆方法能同时完成锚杆定位与周围成孔效果，并使用两次注浆分别对土壤进行改善和对锚杆进行加固，能够有效的防治边坡松动和分离。
