Anchor cable pre-tensioning system and construction method
The invention discloses an anchor cable pre-tensioning system and a construction method, is applied to foundation pit engineering, slope engineering and the manufacturing process of various prestressed components, relates to the technical field of tensioning and locking of prestressed anchor cables in foundation pit supporting, and aims to provide the anchor cable pre-tensioning system and the construction method. The device mainly comprises a limiting device, a limiting plate, a jack and the like. The limiting device is a metal component and comprises a connecting type prefabricated threaded cylinder base, a thin gasket, a hollow screw and a pressure damping spring, and the limiting device can freely stretch out and draw back in the tensioning direction and can be integrally dismantled. Through mutual cooperation of the components in the system, the problem that the anchor cable is stressed unevenly in the pre-tensioning process and the formal tensioning process of the pre-stressed anchor cable can be solved, repeated jack dismounting and mounting work of operators in the tensioning process of the pre-stressed anchor cable can be reduced, and the construction efficiency can be improved.
本发明公开一种锚索预张拉系统及施工方法，应用于基坑工程、边坡工程以及各类预应力构件制造过程中，涉及技术领域为基坑支护中预应力锚索的张拉锁定，目的在于提供一种锚索预张拉系统及施工方法，主要包括限位装置、限位板、千斤顶等；所述限位装置为金属构件，限位装置包含连接式预制螺纹筒底座、薄垫片、空心式螺杆、压力阻尼弹簧，限位装置能够在张拉方向上自由的伸缩并整体拆除；通过此系统中构件的相互配合，能够解决预应力锚索在预张拉和正式张拉过程中锚索受力不均的问题，并且可以减少预应力锚索张拉过程中，作业人员重复拆卸千斤顶及安装工作，可以提高施工效率。
