Hollow bolt manufacturers bolt support in the deep foundation pit slope protection soil or rock layer through drilling and embedding high toughness steel or molecular structure to generate a rod-shaped or strip-shaped structure of materials.

　　One end of the steel bar is anchored in a stable soil layer or rock, and the other end is fixed to the enclosure structure at the slope or the boundary layer of the perforated nozzle through a prestressed anchor. The side load that the enclosure structure receives After the hollow anchor rod manufacturer's hollow anchor rod's pulling and connecting effect is transmitted to the surrounding stable geological structure, it is called the hollow anchor rod supporting structure, which is an active anchor rod supporting structure.

　　Accompany you to advance to understand the principle of the hollow anchor technical anchor rod of the hollow anchor rod manufacturer. The function of the hollow anchor rod in the deep foundation pit retaining structure system software is like an internal support point. It's just that under normal circumstances, the inner support point is a bent prefabricated member, and the hollow anchor is a tensile prefabricated member; the hollow anchor has experienced the overall stability of its steel anchoring force, tensile force and anchor solidity. Participate in the bolt support system software At work.

　　In addition, the pre-stressed tension of the hollow anchor rod of the hollow anchor rod manufacturer releases the pre-stressed steel bar to the sand that is likely to be unbalanced between the stable soil layer and the boundary layer inside the pit wall, which increases the compressive stress of the sand. Either persisting in the tensile strength index values ​​c and φ of the soil layer, or making the soil layer not too loose and reducing its tensile strength index value.

　　The second is that the working pressure of the soil layer in the unbalanced area is likely to increase, which expands the normal stress of the potential sliding surface in the soil layer, and then develops its tensile strength.
