Force self-balance device used in multi-beam anchor rod or anchor cable stretch-pull rod body and construction method thereof

Abstract

Disclosed are a force self-balance device used in multi-beam anchor rod or an anchor cable stretch-pull rod body and a construction method of the force self-balance device. The device comprises a counter-force anchor tool, a hollow lifting jack, a fixing base seat, a revolving piece and an annular cushion piece. The hollow lifting jack is connected with the fixing base seat in a socketing mode. A first elastic magnetism suction device is filled on the socketing position. One end of the revolving piece is movably connected with the fixing base seat. The other end of the revolving piece is connected with the counter-force anchor tool in a socketing mode. A second elastic magnetism suction device is filled on the socketing position. The annular cushion piece is cushioned on the connecting position of the revolving piece and the fixing base seat. Penetrating rib holes coincides with an axis line extension line corresponding to an axis line of an anchor hole of the counter-force anchor tool are all formed in the revolving piece and the fixing base seat. The penetrating rib holes penetrate through a revolving piece body and a fixing base seat body. The technical problems that the anchor rod or the anchor cable is snapped due to the fact that tension of each anchor rod or each anchor cable is different in the stretch-pull process of the existing multi-anchor beam or the anchor cable, thus uniform stress of all the anchor rods or the anchor cables can not be achieved are solved.
一种用于多束锚杆或锚索张拉杆体力自均衡装置及其施工方法,所述装置包括反力锚具和空心千斤顶及固定底座、转动件和环形垫片,所述空心千斤顶与固定底座插接连接,插接部位塞有弹性磁吸装置一,所述转动件一端和固定底座活动连接,另一端与反力锚具插接连接,插接部位塞有弹性磁吸装置二,所述转动件和固定底座连接部位垫有环形垫片;所述转动件和固定底座上均开有轴线延长线与反力锚具的锚孔的轴线对应重合的穿筋孔,所述穿筋孔贯通转动件本体和固定底座本体。解决现有的多束锚杆或锚索在张拉过程中由于每根锚杆或锚索承担的拉力不同导致锚杆或锚索被拉断,无法实现所有锚杆或锚索均匀受力的技术问题。
