Description
Technical field
The present invention relates to bridge structure field, particularly relate to a kind of tramcar plate-girder and construction method thereof.
Background technology
Tramcar is to adopt driven by power the light-duty little marshalling rail traffic vehicles travelled in orbit.Tramcar is a kind of public transport, also known as streetcar or abbreviation electric car, belongs to the one of light railway.Owing to electric car promotes relation with electric power, vehicle will not discharge waste gas, thus is a kind of free of contamination environmental protection vehicles.In recent years, tramcar, as a kind of novel urban track traffic mode, obtains swift and violent development.
The feature that street railway lays is to lay based on bottom surface, and how to lay along the road of existing road, thus can be frequently encountered by the situation that circuit passes through in the middle of current highway and bridge, need the mid portion of current highway and bridge to be reinforced or removes, then redesign the bridge of tramcar.
Tramcar bridge is due to the requirement such as degree of disturbing, the natural frequency of vibration, and deck-molding generally can not be too little.Owing to bottom elevation is required by century-old water level, should flush with highway bridge at the bottom of beam.For existing little span highway bridge, owing to the little span simply supported slab girder construction height of highway bridge is less, and the way of the tramcar bridge of routine is to lay track structure at plate-girder top, accordingly even when tramcar bridge can be accomplished the same with the structure height of highway bridge, also it is difficult to reach track level measuring concordant with current highway and bridge absolute altitude, thus the mixing right of way on bridge can not be realized, also affect the attractive in appearance of bridge structure.
Therefore, it is necessary to provide a kind of mixing right of way and structure tramcar plate-girder attractive in appearance and construction method thereof of realizing to overcome drawbacks described above.
Summary of the invention
It is an object of the invention to provide and a kind of can realize mixing right of way and structure tramcar plate-girder attractive in appearance and construction method thereof.
To achieve these goals, the invention provides the construction method of a kind of tramcar plate-girder, the method comprises the steps:
1) plan-position after substructure construction completes, according to circuit, it is determined that the slotting position in plate-girder main body the dimensional requirement according to track, it is determined that the size of the notch offered in plate-girder main body；
2) colligation spiral, fixed form, reserve the space of notch and need at slotting position place pre-buried track structure to connect reinforcing bar；
3) connecting casting concrete prestressed reinforcement of tensioning bundle on reinforcing bar at reinforcing bar, template and track structure, thus forming plate-girder main body, plate-girder main body being formed with two pairs of notches；
4) assembling reinforcement casting concrete in notch, re-lay track structure, and track structure includes track and the track being located on track；
5) in plate-girder main body, lay waterproof layer and protective layer successively, after laying, the end face of track, plate-girder main body end face concordant with the bridge floor of existing highway bridge.
It is preferred that the axis of symmetry of one pair of which notch and another be 4～4.5m to the distance between the axis of symmetry of notch, the groove width of each notch is 0.5～1m, and the groove depth of each notch is 0.32～0.36m.
It is preferred that the groove width of notch is 0.7m, the groove depth of notch is 0.34m.
It is preferred that waterproof layer is constituted by by polyurethane water-proof paint.
It is preferred that protective layer is made up of C40 fiber concrete.
Additionally; present invention also offers a kind of tramcar plate-girder; including the plate-girder main body being equipped with waterproof layer and protective layer successively; plate-girder main body offers two pairs of notches; each notch is equipped with track; track is equipped with track, the end face of track, plate-girder main body end face concordant with the bridge floor of existing highway bridge.
It is preferred that the axis of symmetry of one pair of which notch and another be 4～4.5m to the distance between the axis of symmetry of notch, the groove width of each notch is 0.5～1m, and the groove depth of each notch is 0.32～0.36m.
It is preferred that the groove width of notch is 0.7m, the groove depth of notch is 0.34m.
It is preferred that waterproof layer is made up of polyurethane water-proof paint.
It is preferred that protective layer is made up of C40 fiber concrete.
Compared with prior art; on the one hand; the tramcar plate-girder of the present invention is creationary slots at back; and track structure is imbedded in notch; namely being built in beam body, greatly reduce the rail level absolute altitude of circuit, so that slab and girder has been constructed, the back absolute altitude after waterproof layer and protective layer is consistent with rail level absolute altitude; and then achieve the mixing right of way of tramcar bridge and highway bridge, and save construction investment.On the other hand, when adopting the tramcar slab and girder of the present invention, it is only necessary to remove the plate-girder of existing highway bridge in tramcar width range, there is higher economic benefit and social benefit.
By description below and in conjunction with accompanying drawing, the present invention will become more fully apparent, and these accompanying drawings are used for explaining embodiments of the invention.
