The invention discloses a pressure dispersion type anchor cable for slope treatment. The pressure dispersion type anchor cable is characterized in that a limiting plate, an extrusion sleeve, spiral ribs and a bearing plate form a combined body to effectively relieve large local pressure of an anchor cable steel bar, so that the service life of the anchor cable steel bar and the actual slope supporting effect are guaranteed. After the spiral ribs are solidified into a whole through grouting of a grouting pipe, stress on the bearing plate can be effectively relieved, the service life of the bearing plate is guaranteed, the service life of the whole anchor cable is guaranteed, and concrete behind the rear side face of the bearing plate is prevented from being crushed. On the front side face of the bearing plate, the limiting plate is connected to the front side face of the bearing plate through a pull rod, a stable consolidation body is formed on the front side face of the bearing plate after grouting, the bearing capacity of the anchor cable is improved, the extrusion sleeve is formed at the head end of a prestressed tendon in an extrusion manner, and the service life of the prestressed tendon is guaranteed. According to the pressure dispersion type anchor cable, the problem that concrete behind a bearing plate in an existing pressure dispersion type anchor cable is prone to being crushed is solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a pressure-dispersing anchor cable used for slope control. Background technique [0002] In the existing slope treatment, the use of pressure dispersion type anchor cable support to control the deformation of rock and soil mass is an effective measure to ensure the stability of rock and soil mass slope. For the pressure-distributed anchor cable, several load-bearing plates in the inner anchor section adjust the bearing capacity of the anchor cable anchor area from different positions, and gradually decay to the free section, and the anchoring force can be adjusted in a large range. [0003] The existing pressure dispersion type anchor cable has the following disadvantages: [0004] During the tensioning process of the anchor cable, the stress on the bearing plate is relatively large, and the concrete behind the bearing plate is easily crushed; [0005] Each set of...
