The invention discloses a transition device for preventing vehicle jumping at a bridge head, comprising an abutment, a roadbed, a first consolidation plate, a second consolidation plate, a first tie plate, a second tie plate, a steel column and a channel steel; The consolidation plate consolidates the abutment end, the second consolidation plate consolidates the road base end, and is hinged with the first and second laps respectively, a slot hole is left between the first lap and the second lap through which the channel steel passes. The slotted hole connects the first deck and the second deck, and the first deck and the second deck can rotate freely with the hinge joint. When there is no settlement difference, the angle between the consolidation plate and the deck is 180 degrees. When the settlement is large, the lap plate and the consolidation plate rotate, and the lap plate and the lap plate are elongated by a certain length, so that there is a transition section between the subgrade section and the bridge abutment. When differential settlement occurs, there is no need to manually adjust the device. The device can be automatically adjusted according to different settlement differences, and is simple to set up and easy to operate.
Description
Technical Field
The invention belongs to the technical field of bridge engineering, and particularly relates to a transition device for preventing vehicle bump at a bridge head.
Background
The road and bridge transition section is a toxic lump which limits the overall rapid development of road traffic, and the bumping at the bridge head becomes a worldwide difficult problem. The main factors causing the bump at the bridge head are as follows: uneven settlement, rigidity mutation, vehicle speed, vibration resistance of the vehicle and the like. In terms of urban road conditions, the uneven settlement is generated at the joint between the flexible road and the rigid structure due to different rigidity, and the dislocation is generated. The bridge and the roadbed pavement are different in material composition, rigidity, strength, expansion and contraction and the like, concentrated stress is easily formed at the bridge head joint when the bridge is stressed, the bridge and the road are settled simultaneously under the action of vehicle load, structural dead weight and natural factors, but the settlement amount of the bridge and the road is greatly different, and the settlement amount of the road is far greater than that of the bridge to form a wrong platform, so that bridge head bumping is caused during driving.
At present, the method for solving the problem of bump at the bridge head mainly comprises the steps of arranging a bridge head butt strap, a geogrid and the like, and some methods obtain better effects and some methods are not satisfactory. If the bridge head butt strap is arranged, the bridge head butt strap can be broken along with the settlement of the embankment, and further the height transition and the bearing capacity which are required are lost.
The bump at the bridge head not only directly affects the traffic capacity of roads, but also affects the comfort and the safety of driving, and the bump at the bridge head can also damage transported objects, so that the bump at the bridge head is discussed, the bump at the bridge head is comprehensively analyzed, reasonable and effective prevention measures and maintenance schemes are provided, and great economic benefits and social benefits are achieved.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a transition device for preventing the vehicle bump at the bridge head. The device can effectively solve the problem of bumping at the bridge head caused by uneven settlement of the rigid abutment and the roadbed.
The specific technical scheme of the invention is as follows:
the invention innovatively designs a transition device for preventing bump at the bridge head, which comprises an abutment, a roadbed, a first consolidation plate, a second consolidation plate, a first butt strap, a second butt strap, a steel column and channel steel;
the first consolidation plate is fixedly connected with the abutment end, the first consolidation plate is hinged with the second consolidation plate through the steel column, the second consolidation plate is fixedly connected with the roadbed section, and the second consolidation plate is hinged with the second butt strap through the steel column and can freely rotate along with the hinge;
slotted holes are reserved on the first butt strap and the second butt strap, and the first butt strap is connected with the second butt strap through the channel steel;
the first butt strap and the second butt strap can freely stretch out and draw back;
the thickness of the channel steel is slightly smaller than the height of the slotted hole, so that the channel steel can better slide in the slotted hole;
the first consolidation plate and the second consolidation plate are consolidated with the abutment end and the roadbed section in an embedded mode, and the size of each component is calculated according to the borne limit load.
Has the advantages that:
when there is no settlement difference, the angle between the consolidation board and the butt strap is 180 degrees, when the settlement of one side of the roadbed is larger, the butt strap and the consolidation board rotate, the butt strap and the butt strap extend for a certain length, so that a transition section is arranged between the roadbed section and the bridge abutment.
