Abstract

The invention discloses a hanging and buckling type anchor cable tensioning machine and an anchor cable secondary tensioning system and relates to the technical field of anchor cable fastening. The hanging and buckling type anchor cable tensioning machine is used for carrying out secondary tensioning on an existing anchor cable which extends out of an existing hole wall. The hanging and buckling type anchor cable tensioning machine comprises a T-shaped anchor disk which is fixedly arranged on the existing anchor cable in a sleeving manner, a force holding steel sleeve which is connected and arranged on the T-shaped anchor disk in a sleeving manner, and force holding steel bars which are connected to the force holding steel sleeve. The axis of the T-shaped anchor disk, the distribution center axis of the force holding steel sleeve and the axes of all the force holding steel bars coincide with one another. A jack which can drive the force holding steel bars to move in the direction far away from the existing hole wall and the anchor disk which can anchor the force holding steel bars are arranged around the force holding steel bar. The hanging and buckling type anchor cable tensioningmachine can achieve secondary tensioning of the existing anchor cable under the situation that the tail of the existing anchor cable is relatively short, tensioning construction does not damage the original structure of the existing anchor cable, operation is convenient and rapid, and application is simple. By means of the anchor cable secondary tensioning system, the secondary tensioning of theexisting anchor cable can be achieved under the situation that the tail 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 a buckle-type 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 ...
