Description

Technical Field

[0001] The utility model relates to the technical field of soil nail wall anchor rods, in particular to a soil nail wall anchor rod fixing device. Background Art

[0002] The natural soil is set with soil nails (also called mortar anchors) by drilling, inserting reinforcement and grouting, and combined with the shotcrete panel to form a soil nail wall similar to a gravity retaining wall to resist the soil pressure behind the wall and maintain the stability of the excavation surface. When installing the existing anchor support, first drill a hole in the soil layer of the pit wall to the required depth, put a steel bar in the hole, and pour cement mortar to combine it with the soil layer to form a tensile anchor rod, which transmits the lateral pressure of the pit wall soil to the stable soil layer. The anchoring end of the common anchor rod is mostly smooth, and the friction between the anchor rod and the wall is too small. When inserted into the soil for concrete pouring, the adhesion between the smooth surface and the wall is small. After a period of use, cracks are very likely to appear, causing the wall to loosen, resulting in the overall stability of the wall being affected.

[0003] When fixing the soil nail wall anchor rods in the above schemes and the prior art, the anchor rods are mostly fixed by directly inserting them into the mounting holes of the wall. During use, the angle of the mounting holes of the wall causes the pad at the end of the aiming rod to fail to fully fit with the wall, which affects the fixation of the soil nail wall anchor rods and cannot meet actual use requirements.

[0004] To this end, the utility model proposes a soil nail wall anchor rod fixing device for solving the above problems. Utility Model Content
