Abstract

The embodiment of the invention provides a railroad bed structure. The railroad bed structure comprises a foundation bed and a road shoulder, wherein the foundation bed comprises a foundation bed bottom layer and a foundation bed surface layer, and the foundation bed surface layer is arranged on the foundation bed bottom layer; the road shoulder is arranged on the foundation bed bottom layer and located on the side edge of the foundation bed surface layer, and steps with at least two steps are formed on the side, away from the foundation bed surface layer, of the road shoulder. According to the railroad bed structure, railway maintenance personnel can go up and down the road shoulder conveniently, and then the safety of the railway maintenance personnel going up and down the road shouldercan be improved.

Description

technical field [0001] The invention relates to the field of railway roadbed protection structures, in particular to a railway roadbed structure. Background technique [0002] In order to ensure the stability of the surface filling of the subgrade bed and the stability of the subgrade equipment, the railway subgrades in the related art are generally provided with road shoulders, so that the railway maintenance personnel can walk and carry out related inspections. The height difference is relatively large, and it is inconvenient for railway maintenance personnel to go up and down the road shoulder, and there are certain safety risks. Contents of the invention [0003] In view of this, the main purpose of the embodiments of the present application is to provide a railway subgrade structure that is convenient for railway maintenance personnel to get on and off the road shoulder. [0004] In order to achieve the above-mentioned purpose, the technical scheme of the embodiment ...
