Prestressed anchor cable uniform tensioning device and method
The invention discloses a prestressed anchor cable uniform tensioning device and method. The prestressed anchor cable uniform tensioning device comprises an outer oil cylinder, inner oil cylinders, aliquid separating plate and cross-core sleeves. The multiple inner oil cylinders are arranged and uniformly arranged in the outer oil cylinder, and the inner oil cylinders are fixed in the vertical direction. A piston rod is arranged in each inner oil cylinder. The cross-core sleeves are arranged in the piston rods. The upper portions of the cross-core sleeves are free ends, the bottoms of the cross-core sleeves are fixed to the outer oil cylinder, and through holes are formed in the corresponding positions, at the bottoms of the cross-core sleeves, of the outer oil cylinder. The liquid separating plate is arranged in the outer oil cylinder and used for separating an oil cavity of the outer oil cylinder into a first oil cavity body and a second oil cavity body; a first oil nozzle is arranged on the side wall of the first oil cavity body of the outer oil cylinder, and a second oil nozzle is arranged on the side wall of the second oil cavity body of the outer oil cylinder; and an oil cavity of each inner oil cylinder is separated into a third oil cavity body and a fourth oil cavity body by the corresponding piston rod, a first pore passage is formed in the side wall of each third oilcavity body, and a second pore passage is formed in the side wall of each fourth oil cavity body.
本发明公开了一种预应力锚索均匀张拉装置及方法，包括外油缸、内油缸、隔液板和穿心套筒；所述的内油缸包括多个，均匀设置在外油缸内，内油缸上下固定；在每个内油缸内设有活塞杆，在活塞杆内设置有穿心套筒，穿心套筒上部为自由端，底部固定在外油缸上，在穿心套筒底部对应位置的外油缸上设置有通孔；在外油缸内设置隔液板，用于将外油缸的油腔分隔为第一油腔和第二油腔；外油缸的第一油腔侧壁和第二油腔侧壁分别设有第一油嘴和第二油嘴；活塞杆将内油缸的油腔分隔为第三油腔和第四油腔，第三油腔侧壁和第四油腔侧壁分别设有第一孔道和第二孔道。
