Large-tonnage anchorage structure on steep slope and construction method of large-tonnage anchorage structure
The invention provides a large-tonnage anchorage structure on a steep side slope and a construction method thereof.The anchorage structure comprises a group of multi-group #-shaped frame structures, each #-shaped frame structure is formed by connecting a plurality of pressing beams and anchor beams, and the #-shaped frame structures are supported and fixed to the side slope through scaffold steel pipes; preformed holes are reserved in the pressing beam and the anchor beam and are used for allowing the prestressed rock anchor cable and the anchor cable to penetrate through respectively; the prestressed rock anchor cable anchors the #-shaped frame structure on the side slope, and the anchor cable is anchored on the anchor beam. The anchoring force of the prestressed rock anchor cable can be effectively conducted out, a large-size concrete structure is not needed, the influence of the terrain gradient and the rock stratum geological condition is avoided. Meanwhile, slope reinforcement can be considered, and the method is suitable for being used for various rear anchor structures of arch bridges constructed through a cantilever method.
本发明提供了一种陡峭边坡上的大吨位锚碇结构及其施工方法，所述锚碇结构包括一组多组井字架结构，单个井字架结构由若干压梁与锚梁连接组成，所述井字架结构通过脚手架钢管支撑固定在边坡上；所述压梁与锚梁上均预留加工有预留孔并分别用于穿过预应力岩锚索及锚索；所述预应力岩锚索将井字架结构锚固于边坡上，锚索锚固于锚梁上。能够有效将预应力岩锚索锚固力传导出来，不用借助大体积混凝土结构物，不受地形坡度及岩层地质情况影响，同时能够兼顾边坡加固使用，适用于各种采用悬臂法施工拱桥的后锚结构使用。
