Abstract

The invention discloses a combined bearing plate comprising an outer bearing plate and an inner bearing plate. The outer bearing plate comprises an annular outer bearing plate body; arc grooves I for mounting prestressed tendons are formed in the outer edge of the outer bearing plate body; and an annular step hole I is formed in the center of the outer bearing plate body. The inner bearing plate comprises a circular inner bearing plate body; and an annular step I is arranged on the outer edge of the inner bearing plate body. In a using state, the annular steps I of the outer bearing plate and the inner bearing plate are mutually matched and connected to be a whole through a screw to form the composite bearing plate. An inner anchorage section of the pressure-uniformly-distributed anchor cable comprises an anchor cable body and a multistage cable body bearing structure. A bearing plate of each-stage cable body bearing structure is the combined bearing plate, wherein the combined bearing plate comprises the outer bearing plate and the inner bearing plate, and a limiting plate of each-stage cable body bearing structure is also the combined limiting plate. According to the combined bearing plate of the invention, the problem that interference exists when the large hole-position pressure-uniformly-distributed anchor cable bearing plate and limiting pieces are mounted is better solved.

Description

technical field [0001] The invention relates to a load-bearing plate and an installation and use method thereof, in particular to a combined load-bearing plate suitable for large-hole-position pressure-uniformly-distributed anchor cables, pressure-uniformly-distributed anchor cables and installation and manufacturing methods thereof. Background technique [0002] The pressure uniform anchor cable has the characteristics of more uniform shear stress distribution in the inner anchorage section, greater bearing capacity, more reliable anchor cable anchoring, and easier construction. It is worth popularizing and applying as a new type of anchor cable in geotechnical engineering; At present, the structure of the load-bearing plate used for the pressure-distributed anchor cable and the pressure-uniform anchor cable is as described in the patent No. 201320512838.X "tension-compression dispersed anchor cable load-bearing plate"; The installation holes are arranged in more than 2 cir...
