Multistage energy dissipation and shock absorption reinforced soil double-faced roadbed retaining wall
Concrete retaining walls are poured at the bottoms of the two sides of a rail, memory sponges are fixed to the inner side faces of the concrete retaining walls on the two sides, and meanwhile single-point displacement meters are installed on the memory sponges; a plurality of parallel geogrids are arranged in the middle area of the concrete retaining wall, a driving shaft and a driven shaft are fixed in the middle, one end of each geogrid is hinged to the driven shaft, and the other end of each geogrid extends into the concrete retaining wall to be fixed. A box-shaped anti-seismic foundation is arranged below the geogrid, an upper steel plate and a lower steel plate are connected through limiters on the left side and the right side, a rubber air cushion is arranged in a formed box structure, and an elastic element is arranged in the formed box structure. The device is provided with a three-stage cushioning structure, the practicability is high, manufacturing and machining are convenient, and the anti-seismic effect is excellent.
本发明公开了一种多级耗能减震加筋土双面路基挡墙，在铁轨两侧底部浇筑混凝土挡墙，在两侧的混凝土挡墙内侧面固定记忆海绵，同时在记忆海绵上安装单点位移计；在混凝土挡墙中间区域内布置多块相互平行的土工格栅，在中间固定有一主动轴和从动轴，土工格栅一端与从动轴相铰接，另一端则延伸至混凝土挡墙中固定；在土工格栅下方设置有箱体形抗震基础，上钢板和下钢板之间通过左右两侧的限位器连接，在组成的箱体结构内部设置橡胶气垫，在内部设置弹力元件。本发明装置设置有三级缓震结构，实用型强且方便制作加工，抗震效果优异。
