Half-road and half-bridge structure

Abstract

The invention discloses a half-road and half-bridge structure. The half-road and half-bridge structure comprises a bridge, a roadbed backfill layer and an access plate. The roadbed backfill layer is arranged on the lower portion of the access plate. The access plate and the bridge are arranged side by side, and an extensible joint is arranged between the access plate and the bridge. A bridge floorpavement layer is arranged on the bridge. A road surface pavement layer is arranged on the access plate. The bridge floor pavement layer and the road surface pavement layer are arranged at intervalsto form an installation groove. The extensible joint is located under the installation groove. A bracket is arranged on one side of the bridge. An access plate connecting end and an access plate mainbody section are arranged on the access plate in the width direction of the roadbed backfill layer. The connecting end of the access plate is arranged on the bracket and is connected with the bracket.The access plate main body section is supported on the roadbed backfill layer. According to the half-road and half-bridge structure, the phenomenon of dislocation of the extensible joint between thehalf-road and the half-bridge is effectively avoided, smooth and comfortable driving is achieved, the phenomenon of stagger is reduced, the damage of a car and the destruction of the extensible jointare reduced, and the number of repairing is reduced.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a half-road half-bridge structure. Background technique [0002] With the development of highway construction in our country, the evaluation of the quality of use and service of a highway includes indicators such as speed, safety, and comfort, and whether it is comfortable and smooth is a very important evaluation standard. On mountainous roads, due to the steep terrain, the lower side of the road is too high to build a retaining wall or to backfill the slope, and the ground on the upper side of the mountain is relatively low in elevation relative to the road surface. In this case, a half-road and half-bridge structure is often designed. The bridge is built on the lower side of the mountain, and the roadbed is built on the upper side of the mountain by using the shoulder retaining wall. In the previous design of half-road and half-bridge, the longitudinal joint betwe...

AI Technical Summary

Problems solved by technology

Due to the high overall rigidity of the bridge structure, compared with the connected embankment which is a flexible structure, the rigidity of the two is different, and the settlement after the road operation is also different. The settlement of the bridge is small, and the settlement of the roadbed is large. There will be a phenomenon of wrong platform, resulting in uneven and uncomfortable driving, which can easily damage the car and damage the expansion joints, affect the traffic, and cause the project to be repaired many times
