Assembled floating column type inspection pit vibration isolation system for rail transit
The invention discloses an assembly type floating column type inspection pit vibration isolation system for rail transit. The assembly type floating column type inspection pit vibration isolation system is arranged between an upper cover building and a rail of the rail transit, and comprises a plurality of assembled floating column type inspection pit units which are sequentially connected end toend to form an elongated column type inspection pit, each assembled floating column type inspection pit unit comprises a prefabricated bottom plate and a plurality of prefabricated columns; the crosssection of the prefabricated bottom plate is in a U shape, and the prefabricated columns are arranged on protruding parts on the two sides of the prefabricated bottom plate. The upper ends of the prefabricated columns are connected with the corresponding rails; the prefabricated bottom plate is arranged in a groove of the upper cover building located under the rail; concrete beams are arranged atthe bottoms of the grooves, and are arranged corresponding to the convex parts on each side of the prefabricated bottom plate; a plurality of transverse constraints and a plurality of vibration isolators are arranged between the prefabricated bottom plate and the side walls of the two sides of the groove and between the prefabricated bottom plate and the bottom plate correspondingly. The assemblytype floating column type inspection pit vibration isolation system has good vibration reduction and noise reduction performance, and the influence of wheel rail impact vibration of the rail transit train on the vibration comfort of the rail transit upper cover building can be more effectively reduced.
本发明公开了用于轨道交通的装配式浮置柱式检查坑隔振系统，设置于轨道交通的上盖建筑与轨道之间；包括若干依次首尾相连形成长条柱式检查坑的装配式浮置柱式检查坑单元；每一装配式浮置柱式检查坑单元均包括预制底板和若干预制柱；预制底板的横截面呈“凹”字形，两侧凸出部分的上面设有预制柱；预制柱的上端与相应的轨道连接；预制底板设置于位于轨道正下方的上盖建筑的凹槽内；凹槽底部设有混凝土梁，混凝土梁对应预制底板每一侧凸出部分设置；预制底板与凹槽的两侧侧壁和底板之间分别设有若干横向约束和若干隔振器。本发明具有良好的减振降噪性能，能更加有效降低轨道交通列车的轮轨冲击振动对轨道交通上盖建筑振动舒适度的影响。
