Abstract

The invention discloses an assembly type existing anchor cable tensioning device and an existing anchor cable secondary tensioning device, and relates to the technical field of anchor cable fastening.The assembly type existing anchor cable tensioning device is used for secondarily tensioning an existing anchor cable stretching out of an existing anchor disc, and comprises a holding force connector which can be fixedly arranged on the existing anchor cable in a sleeving manner, a plurality of holding force anchor cables which fixedly penetrate through the holding force connector, and a cable bundling device which fixes the middle parts of all the holding force anchor cables together, wherein the axes of the holding force connector and the cable bundling device coincide with the arrangementcentral axis of all the holding force anchor cables; and a jack which can drive the holding force anchor cables to move in the direction away from the clamping force connector, and a holding force anchor disc which can anchor the holding force anchor cables are arranged around the holding force anchor cables. According to the assembly type existing anchor cable tensioning device, secondary tensioning of the existing anchor cable can be achieved in the situation that the tail part of the existing anchor cable is relatively short, and the original structure of the existing anchor cable is not damaged through tensioning construction. According to the existing anchor cable secondary tensioning device, secondary tensioning of the existing anchor cable can be achieved in the situation that thetail part of the existing anchor cable is relatively short.

Description

technical field [0001] The invention relates to the technical field of anchor cable fastening, in particular to an assembled existing anchor cable tensioning device and an existing anchor cable secondary tensioning device. Background technique [0002] Prestressed anchor cables are a common support method for slope support, which apply prestress to the slope through anchor cables. On the one hand, the application of prestress by anchor cables can significantly improve the stress state of the rock and soil on the surface of the slope, and increase the strength of the surface rock and soil. Enhancing the integrity of the slope, avoiding the occurrence of sliding bodies, and ensuring sufficient prestress are the keys to achieve these goals. Usually in engineering construction, when the prestress of the anchor cable is applied in place, according to the design requirements, the tail of the anchor cable is cut off and sealed in the concrete pier to prevent the anchor cable from ...
