Pre-stressed anchor cable isolation support installation structure
The invention provides a pre-stressed anchor cable isolation support installation structure. The pre-stressed anchor cable isolation support installation structure comprises an isolation support and steel strands, multiple threading holes are evenly distributed in the isolation support around the circle center of the isolation support, the threading holes are circular holes, at least two threading holes, opposite to each other, are cone-shaped threading holes, and the middles of the conical slope bevels of the cone-shaped threading holes are each provided with a conical slope upper groove; the steel strands are arranged to penetrate through the cone-shaped threading holes, and wedge-shaped clamping pieces are arranged in gaps between the steel strands and the cone-shaped threading holes in a wedged mode. According to the pre-stressed anchor cable isolation support installation structure, the structure is simple, the manufacturing cost is low, installation is convenient, the defect that a traditional anchor cable installation support moves relative to the steel strands can be effectively avoided, the situation of an anchor cable section without the isolation support caused by moving focusing of the anchor cable hole wall friction does not occur in the down hauling process of a cable on the isolation support, therefore, the defects that the steel strands crack and the anchor cable is scrapped due to the fact that the steel strands wind are avoided, the construction quality of the anchor cable can be effectively guaranteed, and better economic benefits are brought for a project.
