This technology requires that the soil nails be placed centrally in the drilled soil nail holes during construction. The soil nails are steel bars or steel rods that are embedded in the soil after pre-drilling and then form a whole with the soil, playing the role of reinforcing and fixing the soil. The soil nails produce a tensile effect inside the soil, reducing the influence of external forces on the soil and improving the overall stability of the slope.

The device has the characteristics of good soil nail positioning effect and firm anchoring;

[0004] The above patent mentioned that when the soil nail is embedded in the soil, the grouting pipe needs to be placed in the reserved space of the spiral positioning rib on one side of the soil nail first, and then the soil nail and the grouting pipe are inserted into the soil nail hole together. Since the grouting pipe has a certain displacement gap in the space reserved by the spiral positioning rib, the grouting pipe is prone to some shaking during operation, affecting the quality and safety of the grouting operation. Therefore, we proposed a spiral soil nail positioning device. Utility Model Content
