Prestressed anchor cable construction method used in soft soil stratum
The invention discloses a construction method for a pre-stressed anchor cable in a soft soil stratum. The construction method comprises the steps of anchor hole construction, expanded section construction, multiple expanded section construction, pre-stressed anchor cable manufacturing, hole cleaning and anchor cable tensioning and locking. According to the method, the purpose of reaming is achieved by cutting soil on the hole wall through high-pressure water jet in a hydraulic cutting mode, reaming construction of the expanded section is conducted, and therefore the anchoring force of the pre-stressed anchor cable is improved. The reaming operation mode is very simple, the cost can be saved, the construction period of the pre-stressed anchor cable is shortened, and the construction progress is accelerated.
本发明公开了一种用于软土地层中预应力锚索施工方法，该施工方法包括锚孔、扩大段施工、多个扩大段施工、制作预应力锚索、清孔、锚索张拉锁定。本发明通过高压水射流，通过水力切削方式，切削孔壁土体达到扩孔目的，进行扩大段的扩孔施工，从而提高预应力锚索的锚固力。本发明的扩孔操作方式非常简单、可以节约成本，缩短预应力锚索施工的工期，加快施工进度。
