Abstract
The utility model discloses a no expansion joint rigid frame bridge, including girder and abutment. The girder adopts the precast beam, and the girder hoist and mount are placed on the abutment abutment body, the section of watering after the abutment abutment body sets up, and the section of watering behind the abutment body is pour to the girder hoist and mount back of taking one's place, realizes that girder and abutment concrete, flexible base is adopted on the abutment basis, and the bridge floor linear deformation is through the solution that influences each other of the abutment flexible base and the soil body. The utility model discloses mainly there is following advantage: reduce bridge engineering and build the cost. Save the expense of expansion joint and abutment support, subtracted short construction cycle, show saving abutment concrete and pile foundation quantity. Maintenance, upkeep charges hang down. It uses to have saved the maintenance and the replacement cost of expansion joint and abutment support. The bridge does not have the expansion joint, and it is smooth -going comfortable to drive a vehicle.
Description
Technical field
The utility model relates to a kind of jointless rigid frame bridge.
Background technology
Shrinkage joint is one of current bridge construction and the difficult problem in safeguarding.In an atmosphere, environment for use is relatively more severe for the flexible dimension long term exposure of bridge, is be subject to the position of destroying and being comparatively difficult to repair in bridge construction most.China has built part jointless bridge now, but the defect that ubiquity is certain: be still provided with bearing between girder and abutment, need by bearing, girder to be fixedly connected with abutment, bridge domestic demand in application life repeatedly replacing time, the design of jointless brings inconvenience to bearing replacement on the contrary.
In summary, mainly there is following shortcoming in existing jointless rigid frame bridge:
1. need by bearing, girder to be fixedly connected with abutment, bridge domestic demand in application life repeatedly replacing time;
2. abutment foundation is rigid foundation, cannot realize the compatible deformation of abutment foundation and the soil body.
Utility model content
For solving prior art above shortcomings, the utility model provides a kind of jointless rigid frame bridge.
For achieving the above object, the utility model adopts following technical scheme:
Comprise abutment, and by lifting the girder be positioned on abutment abutment body; Described abutment comprises abutment abutment body and abutment foundation, described abutment abutment body the junction with described girder be provided with in order to described girder consolidation after the section of watering, described abutment foundation adopts flexible foundation; Arrange deformation joint at transition slab at bridge head and road joining place, bridge floor longitudinal strain is solved by described abutment flexible foundation and described deformation joint.
Described precast beam adopts precast hollow slab.
Described precast beam adopts prefabricated small box girder.
Described precast beam adopts Precast T-Beam.
The beneficial effects of the utility model are:
Girder adopts precast beam, after precast beam hoisted in position, to build after abutment before the section of watering, is the relation of freely-supported, arranges TR thin rubber pad between the two as temporary support between girder and abutment; Building after abutment after the section of watering, is the relation of consolidation between girder and abutment.It is the process of consolidation after first freely-supported between girder and abutment.
Abutment adopts flexible foundation, allows abutment foundation self to have certain distortion, can interact with the soil body of surrounding, and then solve the longitudinal strain problem of bridge floor.
Bridge, without the need to arranging traditional shrinkage joint, also without the need to arranging bearing, reduces bridge engineering construction costs.Save the expense of shrinkage joint and abutment bearing, shorten construction period; Remarkable saving abutment concrete and pile foundation quantity.
Form of structure is simple, and maintenance, maintenance costs are low.Save maintenance and the replacement cost of shrinkage joint and abutment bearing.
Bridge jointless, drives a vehicle smooth-going comfortable.
Accompanying drawing explanation
Fig. 1; Bridge type elevation;
Wherein: 1. girder, 2. abutment abutment body, 3. abutment foundation, the 4. section of watering after abutment, 5. bridge floor in-situ layer, 6. transition slab at bridge head, 7. deformation joint, 8. TR thin rubber pad.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Girder 1 adopts precast beam (as precast hollow slab, prefabricated small box girder, Precast T-Beam etc.), and girder 1 lifting is placed on abutment abutment body 2, is provided with TR thin rubber pad 8 as temporary support between girder 1 and abutment abutment body 2.Construct after hoisted in position the section of watering 4 after bridge floor in-situ layer 5 and abutment, realizing girder 1 and abutment consolidation, is the process of consolidation after first freely-supported between girder and abutment.Abutment foundation 3 adopts flexible foundation, and transition slab at bridge head 6 and road joining place arrange deformation joint 7, and bridge floor longitudinal strain is by abutment flexible foundation 3 and arrange deformation joint 7 and solve.
Detailed construction operation is as follows:
(1) excavation of foundation pit, construction pile foundation, cushion cap and abutment body;
(2) pit backfill, general backfill is highly no more than 2 meters;
(3) main cable and girder is in place, construction hinge seam or wet seam;
(4) section of watering after bridge floor in-situ layer and abutment of constructing realizes consolidation;
(5) back filling behind abutment compacting, cast-in-place attachment strap, construction Deformation seam and bridge deck, complete bridge construction.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
