Abstract
The utility model discloses a bridge structure, which includes a bridge abutment and a bridge deck. Between the bridge abutment and the bridge deck, a horizontal beam is provided. The bridge structure is characterized in that between the bridge deck and the road plate at the backside bridge abutment, a transitional bridge deck is provided. One end of the transitional bridge deck is connected with the bridge deck in a mobile manner and the other end of the transitional bridge deck is connected with the road plate in a mobile manner. The horizontal beam is arranged beneath the joint point of the bridge deck and the transitional bridge deck. The upper part of the horizontal beam is provided with a mobile supporting block, on which the bridge deck and the transitional bridge deck support. The structure has the advantage that application of massive earthwork projects to eliminate sidesteps formed by the differential sinking of the backside bridge abutment is no longer necessary. When the foundation of the backside bridge abutment sinks, one end of the transitional bridge deck can descend along with the road plate, which forms a slow slope and avoid the generation of sidesteps.
Description
Technical field
The utility model relates to a kind of traffic bridge, especially relates to a kind of bridge construction.
Background technology
Existing highway bridge generally is made up of abutment, bridge, the prefabricated panel of bridge.Modal phenomenon is exactly in the joint of highway and bridge in the existing highway bridge, owing to the formed step of differential subsidence of highway platform back ground and abutment, has caused the jumping car phenomenon of driving vehicle.Bumping at bridge-head is a big technical barrier that always perplexs the highway industry for many years.Jump car and not only cause the discomfort of driving, reduce the travel speed of vehicle and the traffic capacity of road, also can influence the application life of bridge and road application life and vehicle, sometimes even cause traffic accident.And to keep the unblocked of bridge, and then need often bridge to be carried out maintenance and repair, then can increase work of bridge road maintenance and expense thus.For solving this technical problem, the method that adopts in the highway engineering mainly is to improve the density that platform back roadbed bankets at present, for improving real density, adopt different collocation choosing of filler, as adopt gravel, rubble, dirt, adopting light materials such as flyash, polystyrene plastics, foaming perlite in addition is filler, also have and adopt default reverse gradient, changeover portion road surface road pavement is set handles, the method that these compacted density indexs of banketing with raising platform back roadbed reduce roadbed compressive strain is a technical scheme commonly used at present.But this technical scheme is only noticed the control to subgrade settlement, and has ignored the control of foundation settlement.Owing to foundation settlement in the sedimentation of the platform back of the body plays a leading role usually, therefore fill to be difficult to avoid effectively bigger difference to abandon the generation of sedimentation with the compacted density control indexes.On the other hand, bridge platform back construction plant is narrow, and the use of large-scale compacting machinary is restricted, and it is very difficult reaching compacting index density.Number of patent application is to disclose a kind of highway bridge abutment wedge shape soft patch in 03134221.3 the Chinese invention patent prospectus, its technical scheme is: be provided with the double-deck geotechnical grid of one deck on abutment at least, and if do not establish top layer individual layer geotechnical grid under the double-deck geotechnical grid, cushion cap or bottom ground are provided with bottom individual layer geotechnical grid, between top layer individual layer geotechnical grid or double-deck geotechnical grid and bottom individual layer geotechnical grid, be provided with two-layer intermediate layer individual layer geotechnical grid at least, between double-deck geotechnical grid and adjacent one deck intermediate layer individual layer geotechnical grid, between intermediate layer individual layer geotechnical grid and the adjacent one deck intermediate layer individual layer geotechnical grid, compacting has filler between intermediate layer individual layer geotechnical grid and the bottom individual layer geotechnical grid.This patent application utilizes the stereochemical structure of geotechnical grid back-up coat, and formation good integrity, the flexible structure layer that rigidity is big adopt and at road-bridge transition section a kind of highway bridge abutment wedge shape soft patch be set, and have solved jumping car problem preferably.But this technical scheme also exists engineering quantity and increases, and investment increases, and engineering is than complicated problems, and just the roadbed of platform back and abandoning property of the difference sedimentation of ground is had certain effect.
Summary of the invention
Technical problem to be solved in the utility model provides the bridge construction of the step phenomenon that a kind of bridge platform back abandoning property of difference sedimentation simple in structure, that can effectively solve road bridge forms.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of bridge construction, comprise abutment and bridge deck, be provided with the bridge crossbeam between described abutment and the described bridge deck, be provided with the transit bridge panel between the highway plate of described bridge deck and platform back portion, one end of described transit bridge panel and described bridge deck flexibly connect, the other end of described transit bridge panel and highway plate flexibly connect, described bridge crossbeam is arranged on the below of described bridge deck and described transit bridge panel junction, described bridge crossbeam top is provided with the movable supporting piece, and described bridge deck and described transit bridge panel are bearing on the described movable supporting piece.
Can be provided with first on the described bridge deck and support convex tendon, can be provided with second on the described transit bridge panel and support convex tendon, the described first support convex tendon and described second supports convex tendon and is bearing on the described movable supporting piece.
The end of described highway plate can be provided with breast boards.
Can also be provided with support rim on the described breast boards, also can be provided with the 3rd on the described transit bridge panel and support convex tendon, the described the 3rd supports convex tendon is bearing on the described support rim.
Compared with prior art, advantage of the present utility model is to be provided with a transit bridge panel that flexibly connects with bridge deck and highway plate respectively between the highway plate of bridge deck and platform back portion, the movable supporting piece is set above the bridge crossbeam, do not need to employ again the formed step of abandoning property of difference depression that a large amount of civil engineerings are eliminated the abutment back, when the subsidence of foundations of platform back portion, one end of transit bridge panel can descend with the highway plate, thereby produce the slow inclined-plane of a gradient, avoided the generation of step; And when depression to certain the time, can regulate the height of whole bridge floor by the method for adjusting the movable supporting piece; Because transit bridge panel and highway plate and bridge deck are movably connected, therefore when the highway plate descends, can produce pulling force to the transit bridge panel, and this pulling force can be converted into the pressure to abutment, also can regulate the depression difference of ground and abutment whereby; On bridge deck and transit bridge panel, be provided with respectively and be bearing in first on the movable supporting piece and support convex tendon and second and support convex tendon, can be when the bridge floor run-off the straight, the movable supporting piece stressed evenly; End at the highway plate is provided with breast boards, can stop earth under the highway plate to be squeezed in the space between transit bridge panel and the abutment; And support rim is set on breast boards, and on the transit bridge panel, be provided with and be bearing in the support of the 3rd on support rim convex tendon, then can increase supporting role to the transit bridge panel.The utility model can reach eliminates the purpose of jumping the car phenomenon, the application life of improving bridge and vehicle.
