综合管廊就是地下城市管道综合走廊。即在城市地下建造一个隧道空间，将电力、通信，燃气、供热、给排水等各种工程管线集于一体，设有专门的检修口、吊装口和监测系统，实施统一规划、统一设计、统一建设和管理，是保障城市运行的重要基础设施和"生命线"。
目前城市的管廊由于管线较多，管廊整体采用隧道式的施工方式进行安装，管廊整体呈隧道行内置在土层中，管廊内部架设多个安装管线的槽架，目前市场上针对管廊减震的多少针对槽架的减震，对于浇灌成型的隧道体由于固定一体成型无法进行减震，最多的也是在外部或内部进行减震抵消冲击力的装置，但是在实际地震灾害发生时，管廊隧道整体会在地震纵波和横波中产生整体颤动位移，不同土层的伸缩率容易导致隧道产生裂纹甚至坍塌的问题，在管廊隧道本体一旦发生这类问题时，安装在管廊隧道的槽架会直接脱落损坏，导致管线脱扣损坏。
因此针对上述问题，我们需要一种可以针对管廊隧道进行多级建筑的减震抗震装置。

所述密封弹性接触垫21沿管廊隧道1径向的宽度大于固定架20转动带动内腔筒壁2的最大位移量，这里主要保证内腔筒壁2在发生轻微摆动时，相接的两个密封弹性接触垫21不会错位直接断开密封连接。
所述固定架20的外侧端固定在管廊隧道1的内壁，所述固定架20的内侧端与内腔筒壁2的外壁采用球头连接方式转动相连，设置的球头连接方式不仅可以使内腔筒壁2整体上下摆动而且可以实现左右摆动。
