Abstract

The invention discloses detachable anchor cable tensioning equipment and an anchor cable secondary tensioning system, and relates to the technical field of anchor cable fastening. The detachable anchor cable tensioning equipment is used for secondary tensioning of existing anchor cables protruding from an existing pore wall, and the detachable anchor cable tensioning equipment includes a T-type anchor plate fixedly arranged on the existing anchor cables in a sleeving mode and a force bearing steel sleeve connected to a T-type anchor plate in a sleeving mode; and a jack capable of driving the existing anchor cables to move in the direction away from the existing pore wall is arranged around the force bearing steel sleeve, and a gasket can be arranged between the existing pore wall and the T-type anchor plate in a cushioned mode. According to the detachable anchor cable tensioning equipment, the secondary tensioning of the existing anchor cables with shorter tail portions can be realized, and the existing structures of the existing anchor cables are not destroyed by tensioning construction; and the operation is convenient and efficient, and the application is simple. According to theanchor cable secondary tensioning system, the secondary tensioning of the existing anchor cables with the shorter tail portions can be realized.

Description

technical field [0001] The invention relates to the technical field of anchor cable fastening, in particular to a detachable anchor cable tensioning machine and an anchor cable secondary tension system. 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 rusting and ensure t...
