Abstract

The embodiment of the invention provides a level crossing structure of rail transit. The level crossing structure comprises a track structure body and a foundation plate, the foundation plate comprises a first part and a second part, the first part is supported below the track structure body, the second part fills an inter-line area between every two adjacent track structure bodies, and the firstpart and the second part are integrally formed. Due to the fact that the first part and the second part are integrally formed, the second part can bear automobile loads and transmit the automobile loads to the first part, and then the first part evenly transmits the loads to a roadbed foundation bed of a track structure. In this way, it is guaranteed that the roadbed foundation bed under the double-line or multi-line track structure is evenly stressed, and uneven settlement caused by uneven stress of the roadbed foundation bed under the double-line or multi-line track structure is prevented.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a level crossing structure of rail transit. Background technique [0002] The level crossing sections of the existing rail transit are mostly two-lane rail transit and roads interlaced. Under the repeated action of traffic load, the track structure of the left and right lines is prone to uneven settlement, which affects the smoothness of the road. Contents of the invention [0003] In view of this, the embodiment of the present application expects to provide a level crossing structure of rail transit to solve the technical problem of uneven settlement of the track structure of the left and right lines of the level crossing section in the prior art. In order to solve the above-mentioned technical problems, the technical solutions of the embodiments of the present application are implemented in the following way: [0004] The embodiment of the present application ...
