Anchor cable prestress compensation construction method
The invention discloses an anchor cable prestress compensation construction method. The method comprises the following steps that S1, a stratum working face at the anchor cable outcrop position is cleaned; s2, a limiting plate is arranged at the exposed end of the anchor cable in a penetrating mode; s3, an anchor cable connector is installed, and the two ends of the anchor cable connector are connected with the outcrop end of the anchor cable and an external long anchor cable correspondingly; s4, a prestress transmission sleeve penetrates from the upper end of the externally-connected lengthened anchor cable and is arranged on the surface of the anchor cable connector in a sleeving mode, and one end of the prestress transmission sleeve abuts against the limiting plate; s5, a center hole jack is arranged on the external long anchor cable in a sleeving mode; S6, a tool anchor is arranged on the external long anchor cable in a sleeving mode; s7, an oil pump of the center hole jack is started, oil pressure is applied to the center hole jack, the prestress can be well and efficiently increased again for the anchor cable, and the risk of slope instability under the aging effect is greatly reduced.
本发明公开了一种锚索预应力补偿施工方法，包括如下步骤：S1、清理锚索露头位置的地层工作面；S2、将限位板穿设在锚索的露头端；S3、安装锚索连接器，其两端分别连接锚索的露头端和外接长锚索；S4、将预应力传递套筒从外接接长锚索上端穿入，套设在锚索连接器表面，所述预应力传递套筒一端相抵于在所述限位板上；S5、将穿心千斤顶套设在所述外界长锚索上：S6、将工具锚套设在所述外界长锚索上；S7、启动穿心千斤顶的油泵，对穿心千斤顶施加油压，本发明能够较好、高效的为锚索重新增加预应力，极大的降低了时效作用下边坡失稳的风险。
