Bridgehead transition slab structure for hydraulic engineering

Abstract

The invention discloses a bridgehead transition slab structure for hydraulic engineering, relates to the technical field of building bridges, and improves a condition of bridgehead bumping. Accordingto the technical scheme, the invention discloses the bridgehead transition slab structure for hydraulic engineering. A bridge abutment is included. A bracket is integrally arranged on one side of thebridge abutment; a vertically-arranged anchor rod is integrally poured into the upper surface of the bracket; a bridgehead transition slab is also supported on the bracket; one side of the bridgeheadtransition slab is supported on the bracket; and steel pipes with inner diameters larger than the diameter of the anchor rod are pre-poured into the bridgehead transition slab, the steel pipes are evenly arranged in the side edge direction of the bridgehead transition slab at intervals, the upper ends of the anchor rods are arranged in the steel pipes in a sleeved mode when the bridgehead transition slab is supported on the bracket, and the steel pipes are filled with asphalt mastic. The structure is reasonable, and a bridgehead bumping situation caused by a height difference between the bridgehead and filled soil can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of building bridges, in particular to a bridge head buttress structure for water conservancy projects. Background technique [0002] Vehicle jumping at the bridge head refers to the deformation, breakage, or even potholes of the road surface or the board in the whole area connecting the road and the back of the bridge platform, so that the vehicle driving through this area will experience obvious jumps and bumps after being impacted. With the increasing traffic flow The phenomenon of vehicle jumping at the bridge head is more and more common on all levels of highways. The vehicle bumping caused by the phenomenon of vehicle jumping will not only cause discomfort to the people in the vehicle, but even cause the vehicle to lose control, pose a threat to safety, and seriously affect road traffic safety. , although the majority of highway practitioners have made every effort to solve this problem from d...

[0002] Vehicle jumping at the bridge head refers to the deformation, breakage, or even potholes of the road surface or the board in the whole area connecting the road and the back of the bridge platform, so that the vehicle driving through this area will experience obvious jumps and bumps after being impacted. With the increasing traffic flow The phenomenon of vehicle jumping at the bridge head is more and more common on all levels of highways. The vehicle bumping caused by the phenomenon of vehicle jumping will not only cause discomfort to the people in the vehicle, but even cause the vehicle to lose control, pose a threat to safety, and seriously affect road traffic safety. , although the vast number of highway practitioners have tried to solve this problem from design to construction, the problem of vehicle jumping at the bridge head has not been well resolved.
