Rail transit pile foundation floating slab vibration reduction structure and construction method
The invention discloses a rail transit pile foundation floating slab vibration reduction structure and a construction method. The structure comprises a station structure, a ballast bed, a pile foundation, a vibration isolator and a structure bottom plate. A plurality of holes are evenly formed in the structural bottom plate, the pile foundation is of a cylindrical structure and penetrates through the holes in the structural bottom plate, and gaps are reserved between the pile foundation and the hole walls in the structural bottom plate. The vibration isolator is arranged between a hole wall on a structural bottom plate and a cylindrical surface of a pile foundation and comprises an inner-layer sleeve serving as an inner supporting structure, an outer-layer sleeve serving as an outer supporting structure and a vibration isolation body arranged between the inner-layer sleeve and the outer-layer sleeve. Connection between the pile foundation and a main body structure of a station structure is separated through the vibration isolators so as to reduce vibration waves generated at the joint of the pile foundation and the main body structure, the track bed provides support for an upper structure of rail transit, and the pile foundation changes the propagation path of the vibration waves so that the vibration waves can be propagated to the deep layer of a soil body. The vibration source vibration reduction and the propagation path vibration reduction of the rail transit structure are combined.
本发明公开了一种轨道交通桩基浮置板减振结构及施工方法，结构包括：车站结构、道床、桩基础、隔振器以及结构底板；所述结构底板上均匀开有多个孔，所述桩基础为圆柱形结构，其穿过该结构底板上的孔，并与该结构底板上的孔壁之间留有空隙；所述隔振器设于结构底板上的孔壁与桩基础的柱面之间，包括作为内支撑结构的内层套筒、作为外支撑结构的外层套筒以及设于所述内层套筒与外层套筒之间的隔振体；通过所述隔振器将桩基础与车站结构的主体结构之间的连接脱离，以减轻二者连接处产生的振动波，所述道床为轨道交通的上部结构提供支撑，所述桩基础改变振动波的传播路径，使其向土体深层传播，实现轨道交通结构的振源减振和传播路径减振相结合。
