Abstract

The invention relates to an anchor cable prestress control device and a using method, and the anchor cable prestress control device comprises a prestress adjusting assembly which comprises a control structure, a driving structure and an execution structure, the control structure is electrically connected with the driving structure, the driving structure is connected with the execution structure, and the execution structure comprises a manipulator shell and a manipulator; the lock assembly comprises a clamping piece, an inner anchor ring, an outer anchor ring and a lock shell, the clamping piece clamps the anchor cable, the clamping piece is fixed in the inner anchor ring, the inner anchor ring is located in the outer anchor ring and matched with the outer anchor ring through threads, and the outer anchor ring is rotatably installed in the lock shell; the prestress detection structure is electrically connected with the control structure, and the prestress detection structure is arranged on the lock shell; the manipulator is matched with the outer anchor ring to drive the outer anchor ring to rotate, and the rotation of the outer anchor ring drives the inner anchor ring to move axially. The anchor cable solves the problem that in the prior art, time and labor are wasted in stress compensation of anchor cables.

Description

technical field [0001] The present application relates to the technical field of tunnel anchor cables, and in particular, to an anchor cable prestress control device and a method of using the same. Background technique [0002] In engineering construction, the stability of the tunnel is particularly important. The collapse of soil and rock in the tunnel will cause significant loss of life and property. The soil and rock in the tunnel are usually fixed by anchor cables. When the foundation pit, tunnel and slope are fixed, the stress calculation is usually performed first. After the prestressed anchor cable is tensioned, different degrees of prestress loss will occur. At this time, the staff is required to perform stress compensation on the anchor cable. When performing stress compensation, manual operation is usually performed by hand, and multiple tests are required. Such operations are time-consuming and laborious, and even have certain risks. [0003] Disadvantages of the...
