Bridge head structure of integral seamless slope bridge
The invention discloses a bridge head structure of an integral seamless slope bridge. The bridge head structure can eliminate telescopic seams of the bridge head at the bottom of a slope. The bridge head structure comprises a main girder, an integral bridge abutment, a bracket behind the bridge abutment, a butting plate, a ground anchor girder and line connecting road surfaces, wherein the main girder and the bridge abutment are integrated, and the bracket behind the bridge abutment is arranged at the back part of the integral bridge abutment; one end, which is lose to the bridge abutment, of the butting plate is placed on the bracket behind the bridge abutment and connected with the main girder through main bars, the ground anchor girder, which is integrated with the butting plate in a pouring manner, is arranged at one end, which is far away from the bridge abutment, of the butting plate, and the ground anchor girder extends into a ground base layer; at least one layer of reinforcing steel bars is arranged in the butting plate, and each of the reinforcing steel bars extends downwards into the ground anchor girder; the line connecting road surfaces are continuously paved above the main girder and the butting plate. According to the bridge head structure disclosed by the invention, the deformation of the main girder is absorbed by telescopic seams at the top of the slope, and the deformation of the bridge head does not exist at the bottom of the slope bridge, so that the telescopic seams are not needed, and maintenance cost and noise pollution are reduced.
