Abstract

The invention discloses a culvert and roadbed culvert transition structure. The culvert comprises culvert walls, lugs and a bearing platform for supporting line loads, wherein the culvert walls are positioned below the bearing platform, and are correspondingly arranged at the two ends of the bearing platform; the culvert walls and the bearing platform define a duct, and the lugs are positioned outside the duct, the lugs and the bearing platform are combined to form steps, and the top surface of the bearing platform is higher than that of the lugs. According to the technical scheme of the culvert and the roadbed culvert transition structure, it is guaranteed that the transition structure and the culvert are stressed together, and the settling volume of the transition structure and the culvert is basically consistent, so that the phenomenon that the settlement between the culvert and the transition structure is not uniform is reduced, and the driving safety and comfort are ensured.

Description

technical field [0001] The invention relates to the construction of roads and railways, in particular to a culvert and a road-culvert transition structure. Background technique [0002] At present, the treatment of the transitional section between the subgrade and the culvert is mainly to be connected by earth-rock filler, combined with the top soil covering of the culvert. In this case, the partial section of the transitional section will cause the longitudinal slope of the line to rise, and the amount of filling will increase, resulting in an increase in project costs. And because the culvert is a rigid structure, the earth-rock filling is mostly a semi-rigid or flexible structure in the transition section. The settlement time of the earth-rock filling is long, and the settlement is generally slightly larger than that of the frame culvert. Therefore, uneven settlement is prone to occur in culverts and transition sections, which affects driving safety and comfort. Content...
