Description

Technical Field

[0001] The invention relates to the technical field of anchoring, in particular to a prefabricated anchor cable frame. Background Art

[0002] The anchor cable is a prestressed steel strand that passes through the sliding surface of the slope with its outer end fixed to the slope surface and the other end anchored in the stable rock mass within the sliding surface. It directly generates anti-sliding resistance on the sliding surface, increases the anti-sliding friction resistance, and puts the structural surface in a compressed state to improve the integrity of the slope rock mass, thereby fundamentally improving the mechanical properties of the rock mass, effectively controlling the displacement of the rock mass, and promoting its stability, so as to achieve the purpose of regulating bedding, landslides, and dangerous rocks and stones.

[0003] The anchor cable frame is a light structure with an open grid system structure, which is conducive to slope greening. At the same time, it has a frame hoop effect on the slope and has good seismic performance. It is currently the main structural form for slope reinforcement and disease control. The anchor cable frame in the prior art is generally cast on site. During construction, it is necessary to erect molds, install steel bars and pour concrete on the slope surface. The tensioning of the prestressed anchor cable must wait until the external anchor structure, i.e., the frame, reaches its designed strength before it can be tensioned. As a result, the overall construction cycle is often seriously delayed due to the construction and maintenance of the frame. In addition, due to the slow construction speed of the frame, the opportunity for slope reinforcement is missed. Even the slope instability has occurred before the anchor cable is tensioned. Moreover, it usually takes 28 days for the cast-in-place anchor cable frame to solidify before it can be used normally, which greatly delays the construction time. At the same time, the existing casting increases the difficulty of construction. At the same time, after the concrete is damaged, later maintenance is difficult. Summary of the invention
