Beam string type structure back shore system suitable for CFRP (carbon fiber reinforced plastic) cable
The string structure jacking system suitable for the CFRP cable comprises a supporting rod jacking section and a jacking device, the supporting rod jacking section is located at the top of the jacking device, and a main supporting rod is arranged at the top of the supporting rod jacking section; the supporting rod top supporting section comprises an upper connecting plate, a lower connecting plate, auxiliary supporting rods and an arc-shaped cable groove, the upper connecting plate and the lower connecting plate are connected through the auxiliary supporting rods, the bottoms of the auxiliary supporting rods penetrate through the lower connecting plate, the lower connecting plate can move along the auxiliary supporting rods, and the arc-shaped cable groove is formed in the upper end of the lower connecting plate; the jacking device comprises a reaction frame, a jack, an upper transfer beam and a lower transfer beam, the upper transfer beam and the lower transfer beam are arranged in the reaction frame, and the jack is arranged between the upper transfer beam and the lower transfer beam. According to the scheme, the arc-shaped cable groove is formed, the cable body can be prevented from forming a bending point, the relative distance between the upper connecting plate and the lower connecting plate can be adjusted according to the needed jacking distance, the jacking function is achieved, and tensioning of the CFRP cable is avoided.
本发明提供一种适用于CFRP索的张弦式结构顶撑系统，包括撑杆顶撑段和顶撑装置，撑杆顶撑段位于顶撑装置的顶部，且撑杆顶撑段的顶部设置有主撑杆；撑杆顶撑段包括上连接板、下连接板、副撑杆和弧形索槽，上连接板和下连接板之间通过多个副撑杆连接，副撑杆的底部贯穿下连接板，且下连接板能够沿副撑杆移动，下连接板的上端设置有弧形索槽；顶撑装置包括反力架、千斤顶、上转换梁和下转换梁，反力架内设置有上转换梁和下转换梁，上转换梁和下转换梁之间设置有千斤顶。上述方案中，通过设置弧形索槽，可避免索体形成弯折点，上连接板和下连接板之间的相对距离可根据所需顶撑距离调整，实现了顶撑功能，避免了对CFRP索的张拉。
