Frame anti-seismic energy consumption type bridge channel structure
The invention discloses a frame anti-seismic energy consumption type bridge channel structure which is characterized in that a bottom plate is fixedly connected to the lower surface of a channel, two groups of cross beams are fixedly mounted at the two ends of the lower surface of the bottom plate of a middle section of the channel, two groups of longitudinal beams are fixedly mounted between the two groups of cross beams, and cast-in-place piles are fixedly mounted on the lower surfaces of the two groups of cross beams; the natural gas pipeline protection slab culvert is located below the middle of the bottom plate, and the section in the middle of the channel crosses the natural gas pipeline protection slab culvert through a cast-in-place pile; fixing frames are fixedly installed at the two ends of the lower surface of the bottom plate, fixing assemblies are arranged on the two sides of the lower surface of each fixing frame, buffer assemblies in the fixing frames make contact with the bottom plate, the buffer assemblies are arranged at the joints of the multiple segments, and fixing blocks are fixedly installed on the two sides of each buffer assembly; the problems that a traditional frame bridge channel structure crossing the natural gas pipeline easily generates additional stress on a foundation, normal operation of the natural gas pipeline can be affected, and the anti-seismic property is poor are solved.
本发明公开了一种框架抗震耗能型桥通道结构，通道下表面固定连接有底板，通道中部节段的底板下表面两端均固定安装有横梁，该横梁设置有两组，且两组横梁之间共同固定安装有两组纵梁，两组横梁下表面均固定安装有灌注桩；天然气管道保护盖板涵位于底板中部的下方，且通道中部的节段通过灌注桩上跨天然气管道保护盖板涵；底板下表面两端均固定安装有固定框，固定框下表面两侧均设置有固定组件，固定框内缓冲组件和底板相互接触，缓冲组件位置设置在若干组节段之间的连接处，缓冲组件两侧均固定安装有固定块；解决上述传统上跨天然气管道的框架桥通道结构易对地基产生附加应力，会对天然气管道的正常运营产生影响且抗震性能较差的问题。
