Embodiment Construction

[0009] Such as figure 1 As shown, a fully seamless road and bridge bridge includes a main girder 1, an abutment 2, a slab 3, a corbel 4, and the near abutment end of the abutment is closely connected with the main girder through the main reinforcement 5, and the far abutment end of the abutment is placed on the corbel above, it is characterized in that the board is inclined relative to the road surface 6, and the inclination i% is the ratio of the height difference h between the near end and the far end to the length l of the board, that is i % = h l · 100 % , Single-layer or multi-layer geotechnical material 7 is set on the full width of the road surface or roadbed above the board, and the geotechnical material extends beyond the tail end.

[0010] Experiments show that the inclination of the board can be 0

[0011] In the present invention, the slab is...

Abstract

A seamless bridge for road is composed of main beams, bridge piers, lap-jointed plates and sleeper beams, and features that said lap-jointed plate is connected between main beam and sleeper beam and one or more layers of earth material are spread on said lap-jointed plate.

Description

Technical field: [0001] The invention belongs to the field of bridges, and in particular relates to the improvement of seamless bridge structures. Background technique: [0002] In traditional small and medium-sized bridge structures, in order to meet the requirements of bridge structure deformation, expansion joints must be provided between the ends of the two girders, between the end of the girder and the abutment, and a 4m-8m long slab is usually installed behind the abutment. The purpose of setting up slabs is to disperse the sudden height difference of staggered platforms at the junction of platforms and dikes to the beam ends of slabs, so as to improve the driving conditions at the transitional section of the road and bridge. The slab is completely separated from the main beam structure, and the near end of the platform is supported on the corbel or back wall behind the platform, the inclination is 0≤i%≤5%, and the embedding depth is divided into three types: ground ty...
