Integral cable withdrawing device for short steel strand inhaul cable and cable withdrawing method thereof
The invention discloses an integral cable withdrawing device for a short steel strand inhaul cable, a fixed supporting leg is mounted on the outer side wall of a pre-buried pipe, a jack is mounted at one end, far away from the pre-buried pipe, of the fixed supporting leg, the other end of the jack is connected with a conversion supporting leg, and a threaded pull rod with two ends extending outwards is inserted into a piston on the jack; one end of the threaded pull rod penetrates through the fixed supporting leg to be connected with a connecting tool for locking and fixing the section, extending out of an anchorage device, of the steel strand, the threaded pull rod is in threaded connection with a second nut with the side wall of one end attached to a piston on the jack, and the threaded pull rod is further in threaded connection with a third nut with the side wall of one end attached to the side wall of the conversion supporting leg. According to the integral cable withdrawing device for the short steel strand inhaul cable, the problem that after construction of the steel strand inhaul cable is completed, the reserved length of the steel strand at the anchoring end is not enough to meet the anchor withdrawing retraction length of the steel strand, so that the cable cannot be withdrawn is solved, old cable force unloading and new steel wire rope inhaul cable replacement are effectively achieved, and integral lengthening and rapid anchor withdrawing are achieved.
本发明公开了一种短钢绞线拉索整体退索装置,所述预埋管的外侧壁上安装有固定撑脚,固定撑脚远离预埋管的一端安装有千斤顶,千斤顶的另一端连接有转换撑脚,千斤顶上的活塞插接有两端向外延伸的螺纹拉杆,螺纹拉杆的一端穿过固定撑脚连接有将钢绞线延伸出锚具的一段锁紧固定的连接工装,螺纹拉杆上螺纹连接有一端侧壁与千斤顶上的活塞贴合的第二螺母,螺纹拉杆上还螺纹连接有一端侧壁与转换撑脚侧壁贴合的第三螺母。本短钢绞线拉索整体退索装置,可以解决钢绞线拉索在施工完成以后锚固端钢绞线留设长度不足以满足钢绞线退锚回缩长度,从而无法退索,有效的实现旧索力卸除和更换新的钢丝绳拉索,并且解决了整体接长快速退锚。
