Deeply-buried anchor cable support pre-tightening force anti-attenuation device and construction method
The invention discloses a deeply-buried anchor cable support pre-tightening force attenuation prevention device and a construction method, and the deeply-buried anchor cable support pre-tightening force attenuation prevention device comprises a shell, and a jacking oil cylinder, a pressure sensor, a first anchor cable anchorage device, a second anchor cable anchorage device and a spring which are arranged in the shell. The device is integrally arranged on the inner side of a pouring structure or a spraying layer and is arranged in the pouring or spraying layer, and when the anchor cable has prestress loss after pouring or spraying is completed, the prestress loss of the anchor cable can be compensated for multiple times in real time through the construction design device; therefore, the problem that in the prior art, prestress loss compensation cannot be carried out only after the anchor cable is put into use is solved, the safety of anchor cable anchoring design engineering is ensured, and in the process that the anchor cable is put into use, multiple times of real-time jacking compensation prestress loss is carried out according to the specific prestress loss condition.
本发明公开了一种深埋锚索支护预紧力防衰减装置及施工方法，其中一种深埋锚索支护预紧力防衰减装置，包括壳体以及设置在壳体内的顶升油缸、压力传感器、第一锚索锚具、第二锚索锚具以及弹簧。本发明整体布置在浇筑结构或者喷层内侧，布置在浇筑或者喷浆层内部，当锚索在浇筑或者喷浆完成后发生预应力损失时，能通过该施工设计装置实时、多次对锚索预应力损失进行补偿，从而解决了现有技术中只能在锚索投入使用后无法进行预应力损失补偿的问题，确保了锚索锚固设计工程的安全性，使锚索在投入使用的过程当中，根据具体预应力损失的情况进行多次、实时顶升补偿预应力损失。
