Prefabricated ballast bed structure capable of reserving vibration reduction and adjusting height
The utility model relates to a prefabricated ballast bed capable of reserving vibration reduction and adjusting height, which can effectively realize the upgrading of the vibration reduction function of the ballast bed and the adjustment of the structure height, is high in transformation and adjustment speed and stable in quality, and is favorable for reducing the construction cost. The prefabricated ballast bed comprises a prefabricated track plate and a track foundation, cap-shaped components are transversely and longitudinally embedded in the prefabricated track plate at intervals, and the lower ends of cap-shaped components are communicated with the bottom face of the prefabricated track plate. Supports are arranged in the cap-shaped components, the support height adjusting gaskets are arranged between the lower ends of the supports and the top face of the track foundation, the reserved gaps are formed between the bottom face of the prefabricated track plate and the top face of the track foundation, and the height of the track structure is adjusted by replacing the support height adjusting gaskets with different thicknesses. And the load on the plate is uniformly transmitted to the track foundation through the cap-shaped components, the supports and the support height adjusting gaskets. Limiting grooves are formed in the two longitudinal ends of the prefabricated track plate, limiting devices fixedly connected with the track foundation are arranged in the limiting grooves, and the limiting devices act on the side walls of the limiting grooves to restrain transverse and longitudinal displacement of the prefabricated track plate.
一种可预留减振及可调节高度的装配式道床，以有效实现道床减振功能的升级和结构高度的调整，改造调整速度快，质量稳固，且有利降低工程造价。包括预制轨道板和轨道基础，预制轨道板内沿板面横向、纵向间隔预埋设置帽形构件，帽形构件的下端与预制轨道板底面相通。帽形构件内设置支座，各支座下端与轨道基础顶面之间设置支座调高垫片，在预制轨道板底面与轨道基础顶面之间形成预留间隙，通过更换不同厚度的支座调高垫片实现轨道结构高度的调节，板上荷载经帽形构件、支座和支座调高垫片均匀传递至轨道基础。预制轨道板的纵向两端具有限位槽，限位槽内设置与轨道基础形成固定连接的限位装置，限位装置作用于限位槽侧壁，对预制轨道板的横向、纵向位移形成约束。
