Abstract
The utility model discloses a kind of end of the bridge highway subgrade structure, which includes: lower part soil structures and the upper part bearing structure that is mounted in the lower part soil structures；The utility model provides end of the bridge highway subgrade structure, improve roadbed overall stability, it can be improved overall stability, reduce settling amount, damage of the driving oscillatory load to highway subgrade can be reduced, improve traffic safety, while can more preferably improve the use of highway subgrade.
Description
Technical field
The utility model relates to road structure field, in particular to a kind of end of the bridge highway subgrade structure.
Background technique
Roadbed treatment is most important in highway engineering, and especially in the area of hydrogeologic condition difference, roadbed treatment is asked
Topic annoyings always researcher, and road-bridge transition section is because roadbed situation is different, subgrade stiffness otherness, long term heavy-load automobile
And impact load, road-bridge transition section roadbed is required to significantly improve, in the case where requiring certain settling amount and bearing capacity precondition,
More require have good deformability, bearing capacity has bigger requirement.
Utility model content
Utility model is designed to provide a kind of end of the bridge highway subgrade structure, solves asking of mentioning in background technique
Topic.
The utility model is realized in this way a kind of end of the bridge highway subgrade structure, under which includes:
Portion's soil structures and the upper part bearing structure being mounted in the lower part soil structures.
The further technical solution of the utility model is: the lower part soil structures include: soil layer, are located on the soil layer
Metalling, the stake of arch lining cutting support, outside pile body, the arch lining cutting support stake and the outside pile body are set up and are passed through vertically
Wear soil layer and metalling.
The further technical solution of the utility model is: the top weighing structure includes: that arch lining cutting and lid are located at
Concrete slab in the arch lining cutting, the arch lining cutting are connect with the arch lining cutting support stake, the concrete slab two
Side rib is connected with outside pile body.
The further technical solution of the utility model is: the arch lining cutting support stake is at least two, the arch cushion
It builds and is equipped with prestress wire between support stake.
The further technical solution of the utility model is: rubber spacer is equipped between the arch lining cutting and concrete slab.
The utility model has the beneficial effects that the utility model provides end of the bridge highway subgrade structure, roadbed monolithic stability is improved
Property, it can be improved overall stability, reduce settling amount, damage of the driving oscillatory load to highway subgrade can be reduced, improve row
Vehicle safety, while can more preferably improve the use of highway subgrade.

Specific embodiment
Embodiment one: Fig. 1 shows a kind of end of the bridge highway subgrade structure, which includes: lower part soil
Body structure and the upper part bearing structure being mounted in the lower part soil structures；The lower part soil structures include: soil layer 1, position
In the metalling 2 on the soil layer, arch lining cutting support stake 3, outside pile body 4, the arch lining cutting support stake 3 and the outside
Pile body 4 is set up vertically and through soil layer 1 and metalling 2；Arch lining cutting support stake and outside pile body all run through soil layer 1 and metalling
2, end multiplies partial action in soil layer, improves overall stability, while improving highway subgrade bearing capacity, arch lining cutting support stake 3,
Top can overarch the support of lining cutting 7, while pile body top is connected by prestress wire 7, improve pile body and laterally hold
Power is carried, while 6 base portion of arch lining cutting, on pile body top, the top weighing structure includes: that arch lining cutting 6 and lid are located at
Concrete slab 5 in the arch lining cutting 6, the arch lining cutting 6 are connect with the arch lining cutting support stake 3, the concrete
5 liang of side ribs of plate are connected with outside pile body 4, improve arch lining cutting support stake 3 described in 5 bearing capacity of top concrete slab and are at least two
Root is equipped with prestress wire 7 between the arch lining cutting support stake 3；It is equipped between the arch lining cutting 6 and concrete slab 5
Rubber spacer 5.1 can play and subtract vibration isolating effect well.
In work progress: being first laid with soil layer part in underlayment, using powder clay, improve its bearing capacity and reduce and sink
Drop amount.Then it is laid with metalling on soil layer top, is mixed using the preferable gravel of gradation, soil and cement, sufficiently after compacting,
Then arch lining cutting support stake to be squeezed into metalling, end acts on soil layer, outer concrete pile body is further squeezed into,
Prestressed steel strand wires are wanted on middle arch lining cutting support stake top, improve its lateral bearing capacity, and improve overall stability, arch
Shape lining cutting support stake top steel strand wires install arch lining cutting after the installation is completed, are then laid with rubber pad in arch lining cutting flattening partially
Layer is finally laid with concrete slab on rubber spacer top, guarantees to be connected with outside concrete-pile just at two side rib of concrete slab
It connects.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
