Non-hydraulic shallow pre-stressed anchor cable tensioning device and construction method
The invention relates to the technical field of pre-stressed anchor cable construction, in particular to a non-hydraulic shallow pre-stressed anchor cable tensioning device and a construction method. A lower elastic clamping piece and an upper elastic clamping piece are clamped on the pre-stressed anchor cable; the lower elastic clamping piece and the upper elastic clamping piece are located in the lower anchorage device and the upper anchorage device respectively. The tensioning spring and the pre-tensioning spring are arranged in a cavity formed by the jack jacking body, the upper anchorage device and the anchor backing plate, the pre-tensioning spring is arranged on the inner side of the tensioning spring, and the supporting column is arranged on the outer side of the pre-tensioning spring; the sliding block and the upper anchorage device enter the jack body from the upper end of the sliding way, and the lower end of the sliding block abuts against the upper anchorage device clamping block. Operation is easy and convenient, an oil pump vehicle is not needed, tensioning can be achieved after installation and opening, repeated recycling can be achieved, manpower and material resource expenses are reduced, and the construction period is effectively shortened.
本发明涉及预应力锚索施工的技术领域，尤其涉及一种非液压式的浅层预应力锚索张拉装置及施工方法。本发明的下弹性夹片和上弹性夹片夹在预应力锚索上；下弹性夹片和上弹性夹片分别处于下锚具、上锚具之中；张拉弹簧和预张拉弹簧设置在千斤顶顶体、上锚具、锚垫板所形成的空腔内，预张拉弹簧置于张拉弹簧内侧，支撑柱置于预张拉弹簧外侧；千斤顶顶体上部设置滑道，滑块和上锚具由滑道上端进入顶体，滑块下端抵住上锚具卡块。本发明操作简便，无需使用油泵车，安装打开后即可张拉且可多次回收，减少人力物力花费和有效缩短工期。
