Abstract

The invention discloses a pressure-dispersion type anchor cable. An inner anchoring section of the pressure-dispersion type anchor cable comprises an anchor cable body and a multi-stage cable body bearing structure. Apart from a first stage bearing plate, other stages of bearing plates are combined-type bearing plates. Limiting plates are also combined-type limiting plates. Each combined-type bearing plate comprises an outer bearing plate and an inner bearing plate. Arc grooves I used for mounting prestressed tendons are formed in the periphery of a circular ring shaped outer bearing plate body of each outer bearing plate. Arc grooves II used for mounting the prestressed tendons are formed in the periphery of a circular ring shaped inner bearing plate body of each inner bearing plate. Injection pipe mounting holes are formed in the centers of the inner bearing plate bodies and inner limiting plates. In a using state, annular step holes I of the inner bearing plates / inner limiting plates are matched with annular step holes I of the outer bearing plates / outer limiting plates, and the annular step holes I of the inner bearing plates / inner limiting plates and the annular step holes I of the outer bearing plates / outer limiting plates are connected to be a whole through screws to combine the combined-type bearing plates / the combined-type limiting plates. According to the anchor cable, the problem that mounting of large hole site pressure-dispersion type anchor cable bearing plates and limiting pieces is complex is solved, the mounting difficulty of the prestressed tendons of inner rings of the anchor cable bearing plates is reduced, and the cable manufacturing efficiency is improved.

Description

technical field [0001] The invention relates to an anchor cable and an installation method thereof, in particular to an anchor cable of a large hole position pressure dispersion type and a production and installation method thereof. Background technique [0002] The pressure-distributed anchor cable has the characteristics of more uniform compressive stress distribution in the inner anchorage section, high single-hole bearing capacity, and more reliable anchor cable anchorage, and has been widely used in geotechnical engineering. At present, the structure of the bearing plate and the limit plate used for the pressure dispersion type anchor cable are as described in the patent No. 201320512838.X "tension and compression dispersion type anchor cable bearing plate". For the second-level and third-level load-bearing structures of the pressure-distributed anchor cable, it is time-consuming and cumbersome to install the prestressed tendons of the inner ring with the existing load-...
