Description

Technical Field

[0002] The use of pressure-dispersed anchor cable support is an effective measure to control the deformation of rock and soil and ensure the stability of rock and soil slopes. Compared with other support measures, pressure-dispersed anchor cable support has the advantages of high bearing capacity, corrosion resistance, and good seismic resistance. It has a good application prospect in the field of geotechnical engineering support.

[0003] The application publication number CN 104831725 A discloses a pressure-dispersing anchor cable, comprising an anchor head, at least two levels of bearing plates arranged in an anchor hole, and at least two groups of anchor cable tendon groups fixedly connected to the corresponding levels of bearing plates respectively; the cross-sectional areas of the anchor cable tendon groups connected to the bearing plates arranged sequentially from the anchor head to the bottom of the anchor hole increase sequentially; the pressure-dispersing anchor cable of the present invention utilizes the stress and deformation properties of the anchor cable tendon material itself, does not need to rely on other control devices, and only adjusts the cross-sectional areas of the anchor cable tendon groups connected to bearing plates at different positions, so that the cross-sectional area of ​​the anchor cable tendon group is adapted to the pressure borne by the corresponding bearing plates, thereby achieving a uniform pressure dispersion effect.

[0004] In the above-mentioned disclosed structure, the pressure plate and anchor cable are connected by separate connections, which not only causes the strength of the local structure to be low, but also is not conducive to the positioning of multiple strands, affecting the stability of the overall structure. In addition, the supporting strength of the dispersed structure is poor, which is not conducive to uniform dispersion in multiple directions and multiple points, affecting the use effect, and needs to be improved.
