The invention relates to the technical field of anchor rod tensioning, and discloses an anchor rod tensioning detection method after anchor sealing, which comprises the following steps: 1) fixedly mounting a plurality of sleeves on an anchor backing plate, and fixedly connecting the lower ends of extended steel bars with the sleeves; (2) a bearing plate is arranged above the anchor bearing plate, and the upper ends of a plurality of extension steel bars are fixedly connected with the bearing plate; (3) a counter-force stool is fixedly arranged on the wall face and provided with a transverse plate, a jack is placed on the transverse plate and provided with a telescopic shaft, and the telescopic shaft abuts against a pressure bearing plate from bottom to top; (4) a telescopic shaft of the jack exerts jacking force from bottom to top on the bearing plate, and the bearing plate exerts upward tensioning force on the anchor bearing plate, the anchorage device and the anchor rod through the extension steel bars; the sleeve is used for connecting the extension steel bar and arranging the jack, the telescopic shaft of the jack jacks the bearing plate, then upward tensioning force is applied to the anchor rod connected to the anchorage device, tensioning detection operation on the anchor rod after anchor sealing is achieved, the structure is simple, and operation is convenient.
Description
technical field [0001] The patent of the present invention relates to the technical field of bolt tensioning, and specifically relates to a detection method for bolt tensioning after anchor sealing. Background technique [0002] As an important form of geotechnical engineering reinforcement, bolt support has been used more and more in the field of geotechnical engineering in my country because of its advantages of safety, high efficiency and low cost. [0003] At present, in bolt support, after the anchor bolt is sealed, due to on-site construction and other reasons, the length of the exposed section of the bolt exposed outside the anchorage is insufficient. When the bolt needs to be tensioned and tested later, it cannot Connect directly to the exposed section for tensioning. [0004] In the prior art, when it is necessary to perform tension detection on the anchored anchor rod, the tension detection cannot be realized due to the insufficient length of the exposed section o...
