Anchor rod tension detection method after anchor sealing

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
