Bedding rock slope protection structure and construction method thereof
The invention discloses a bedding rock slope protection structure and a construction method thereof. The bedding rock slope protection structure comprises grouting holes (1), anchor cables (2), prefabricated nodes (3), prefabricated continuous beams (4), cast-in-place lap joints (5) and multiple anchor cable linkage devices (7). The prefabricated joints (3) and the prefabricated continuous beams (4) are connected into a frame beam structure (6) through cast-in-place lap joints (5). The anchor cables (2) are installed in grouting holes (1) formed after grouting before mountain excavation to form a multi-anchor-cable structure, penetrate through anchoring holes (31) of the prefabricated nodes (3) after mountain excavation, are tensioned through the multi-anchor-cable linkage devices (7) connected with the ends and then are anchored to the prefabricated nodes (3), and the anchor cables, the frame beam structure and a rock mass form a whole. According to the method, the anchor cables are installed through punching and grouting before excavation, the safety coefficient of the excavation process is improved, through the synergistic effect of multiple anchor cable linkage devices, the slope is evenly stressed at different depths, the integrity of a protection structure is enhanced, and the long-term stability of the slope is improved.
本发明公开了一种顺层岩边坡防护结构及其施工方法,结构包括注浆孔(1)、锚索(2)、预制节点(3)、预制连续梁(4)、现浇搭接头(5)及多重锚索联动装置(7)。预制节点(3)和预制连续梁(4)通过现浇搭接头(5)连接成框架梁结构(6)。锚索(2)安装在山体开挖前注浆后的注浆孔(1)中形成多重锚索结构,在山体开挖后穿过预制节点(3)的锚固孔(31),通过端部连接的多重锚索联动装置(7)张拉后锚固在预制节点(3)上,与框架梁结构及岩体形成整体。本发明在开挖前打孔注浆安装锚索,提高开挖过程安全系数,且通过多重锚索联动装置的协同作用,使边坡的不同深度均匀受力,增强防护结构的整体性,提高边坡的长期稳定性。
