Track unit and track structure for bridge
The invention provides a track unit for a bridge, which comprises a base plate, a prefabricated track plate, a self-compacting concrete layer and a vibration reduction layer, and is characterized in that the base plate is positioned on the bridge surface of the bridge; the prefabricated track plate is positioned above the base plate and is formed by offline prefabrication; the self-compacting concrete layer is positioned between the base plate and the prefabricated track plate and is formed by casting self-compacting concrete on site; the vibration reduction layer is located between the self-compacting concrete layer and the base plate. The vibration reduction layer is used for isolating the self-compacting concrete layer from the bridge surface and reducing bridge floor vibration caused by driving loads on the self-compacting concrete layer. The vibration reduction layer facilitates mutual adaptation of deformation of the track unit and the bridge surface, is suitable for the large-span bridge, and improves safety and stability of train operation and structural stability of the bridge. The invention further provides a track structure for the bridge, and the track structure comprises the track unit for the bridge and has the same beneficial effects as the track unit for the bridge.
本申请提供一种用于桥梁的轨道单元，包括底座板、预制轨道板、自密实混凝土层以及减振层，底座板位于所述桥梁的桥面上；预制轨道板位于所述底座板的上方，由线下预制形成；自密实混凝土层位于所述底座板和所述预制轨道板之间，由自密实混凝土现场浇筑形成；减振层位于所述自密实混凝土层和所述底座板之间。减振层用于隔离自密实混凝土层与桥面，减小自密实混凝土层上的行车荷载引起的桥面振动。减振层有利于轨道单元和桥面形变相互适应，适用于大跨度桥梁，提高列车运行的安全性、平稳性以及桥梁的结构稳定性。本申请还提供一种用于桥梁的轨道结构，包括上述用于桥梁的轨道单元，具有与用于桥梁的轨道单元相同的有益效果。
