[0033] The first connecting rod 5 and the second connecting rod 8 have the same length.
[0034] A further optimized solution is that the adjustment component includes threaded rods 9 symmetrically arranged on both sides of the grouting anchor rod 1, a third limiting ring 6 close to the threaded rod 9 is fixedly connected to one end of the threaded rod 9, the other end of the threaded rod 9 is threadedly connected to an internal threaded tube 10, and the end of the internal threaded tube 10 away from the threaded rod 9 is detachably connected to the pad 11.
[0035] According to a further optimized solution, the first limiting ring 2 , the first rubber ring 3 , the second limiting ring 4 , the third limiting ring 6 , the second rubber ring 7 are slidably connected to the inner wall of the PVC sleeve 15 .
[0036] The length of the threaded rod 9 extending out of the internal threaded tube 10 is adjusted by rotating the internal threaded tube 10, and then the cushion block 11 is sleeved on the grouting anchor rod 1, so that the cushion block 11 abuts against the internal threaded tube 10, and the cushion block 11 pushes the internal threaded tube 10 to move, and makes the cushion block 11 tightly abut against the outer wall of the slope protection pile 14, and then the nut 12 is tightened on the grouting anchor rod 1. At this time, the internal threaded tube 10 drives the threaded rod 9 to move, and the threaded rod 9 drives the third limiting ring 6 to move, and the two third limiting rings 6 will squeeze the second rubber ring 7 between the two third limiting rings 6. At the same time, the other two third limiting rings 6 are driven to move through the second connecting rod 8, and the second rubber ring 7 between the two third limiting rings 6 is squeezed. At the same time, the second limiting ring 4 is driven to move through the first connecting rod 5, and the second limiting ring 4 squeezes the first rubber ring 3.

[0037] Working process: first use a drill rod that is compatible with the outer diameter of the PVC sleeve 15 to drill a hole. The drill rod first passes through the slope protection pile 14 and the soil between the slope protection pile 14 and the waterproof curtain 13, and then stops drilling after passing through the middle position of the waterproof curtain 13. At this time, the hole has not penetrated the waterproof curtain 13. Then, insert the PVC sleeve 15 into the hole, and make one end of the PVC sleeve 15 tightly abut against the waterproof curtain 13. Inject water-tight cement slurry into the PVC sleeve 15. After the cement slurry solidifies, drill a hole again with a drill rod that is compatible with the outer diameter of the first limit ring 2. The drill rod forms a hole in the PVC sleeve 15 and penetrates the waterproof curtain 13 to complete the anchor hole construction. Then, the grouting anchor rod 1 is mixed into the anchor hole, and then the internal threaded tube 1 is rotated to 0 Adjust the length of the threaded rod 9 extending out of the internal threaded tube 10, and then sleeve the cushion block 11 on the grouting anchor rod 1, so that the cushion block 11 abuts against the internal threaded tube 10, and the cushion block 11 pushes the internal threaded tube 10 to move, and makes the cushion block 11 tightly abut against the outer wall of the slope protection pile 14, and then tighten the nut 12 on the grouting anchor rod 1. At this time, the internal threaded tube 10 drives the threaded rod 9 to move, and the threaded rod 9 drives the third limiting ring 6 to move, and the two third limiting rings 6 will squeeze the second rubber ring 7 between the two third limiting rings 6. At the same time, the other two third limiting rings 6 are driven to move through the second connecting rod 8, and the second rubber ring 7 between the two third limiting rings 6 is squeezed. At the same time, the second limiting ring 4 is driven to move through the first connecting rod 5, and the second limiting ring 4 squeezes the first rubber ring 3.
[0038] At this time, the grouting anchor rod 1 is pulled outward, and the grouting anchor rod 1 can be pulled outward, which indicates that the outer walls of the first rubber ring 3 and the second rubber ring 7 are not tightly abutted against the inner wall of the anchor cable hole. The nut 12 is removed, and the cushion block 11 is removed, and the internal threaded tube 10 is rotated to increase the length of the threaded rod 9 extending out of the internal threaded tube 10, and then the cushion block 11 is sleeved on the grouting anchor rod 1, so that the cushion block 11 is abutted against the internal threaded tube 10, and the cushion block 11 pushes the internal threaded tube 10 to move, and makes the cushion block 11 tightly abut against the outer wall of the slope protection pile 14, and then the nut 12 is tightened on the grouting anchor rod 1. When the grouting anchor rod 1 cannot be pulled, it indicates that at this time, the outer walls of the first rubber ring 3 and the second rubber ring 7 are tightly abutted against the inner wall of the PVC sleeve 15, and the inner walls of the first rubber ring 3 and the second rubber ring 7 are tightly abutted against the outer wall of the grouting anchor rod 1, which can form a plurality of separate sealing areas, and then grouting is performed in the grouting anchor rod 1.
[0039] The utility model pre-drills a hole before construction, and after drilling, a PVC sleeve 15 is inserted, and watertight cement slurry is poured into the PVC sleeve 15, which can effectively prevent the pore water in the soil behind the water-stop curtain 13 from flowing into the foundation pit, and effectively avoid the pore water pressure at the water-stop curtain 13 from destroying the anchor hole, causing the hole to collapse and the subsequent grouting to be incomplete.
[0040] The utility model is easy to manufacture. It only needs to be drilled twice, and after the first drilling, the PVC sleeve 15 is inserted and grouting is performed, so that water in the soil behind the water-stop curtain 13 can be effectively prevented from flowing into the foundation pit.
