Description
Technical field
The utility model is related to abutment roadbed technical field, specially a kind of platform of prevention car jump between high road bed and bridge
The back of the body.
Background technology
So-called bumping at bridge-head is due to highway end of the bridge and expansion joint（Bridge approach）The relative settlement at place or expansion joint destruction
And make road surface longitudinal slope occur step cause vehicle by when produce jump phenomenon.
Platform carries on the back this section of roadbed while linking main body roadbed, while connect with culvert abutment abutment body, due to road roller pressing less than,
Plus the soil body connect with concrete side produce gap, easily infiltration.And because being connected with concreting body phase, I
Know, the soil body has the characteristic of its natural subsidence, and concreting body is not settled typically, so this section of roadbed is easier to out
Show failure by shear and produce bumping at bridge-head.Therefore this section of roadbed is also high compared with the requirement of main body roadbed, and compactness must reach 96%,
The gravel soil or sandy soil of filler good water permeability.
At present, the precautionary measures of not very good bumping at bridge-head, bumping at bridge-head is multiple, and the reason for it causes problem is a variety of
It is various.
Utility model content
The purpose of this utility model is that providing a kind of platform for preventing car jump between high road bed and bridge carries on the back, and possesses from many aspects
Prevent the advantage of high filling subgrade sedimentation, solve due to causing the varied high filling subgrade of reason to settle asking for bad prevention
Topic.
To achieve the above object, the utility model provides following technical scheme：One kind prevention car jump between high road bed and bridge
The platform back of the body, including the bridge that roadbed table top and roadbed table top side connect, the bottom of the roadbed table top is provided with fill stratum, institute
State the lap slab of bridge that with side bridge overlaps of the fill stratum including top, the broken stone pile being symmetrically pressed into inner chamber, lap slab of bridge
The stone filled between the short steelframe of inner support and the long steelframe of inner support, the short steelframe of inner support and the long steelframe of inner support and lap slab of bridge of bottom connection
The green stone slag filler filled between the short steelframe of grey hardcore, inner support and the long steelframe of inner support and broken stone pile, the long steelframe of inner support and permeable
The secondary crushed rock filler filled between bottom plate.
It is preferred that, the entirety that the short steelframe of the lap slab of bridge, inner support, the long steelframe of inner support, broken stone pile and permeable bottom plate are constituted
Lateral section is rectangle, and whole interior is divided into five triangles by the short steelframe of inner support and the long steelframe of inner support.
It is preferred that, the surface of the permeable bottom plate is provided with leaking hole.
It is preferred that, remaining of the inner chamber of the fill stratum is banketed as original soil layer soil.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is by setting the short steelframe of broken stone pile, inner support, the long steelframe of inner support, permeable bottom plate, secondary rubble to fill out
In material, green stone slag filler, limestone filler and lap slab of bridge, the combination by broken stone pile, the short steelframe of inner support and the long steelframe of inner support,
It ensure that whole fill stratum will not produce deformation, even if global shape is in infall process, also ensure the consistent of shape, simultaneously
Also overall anti-pressure ability is improved, mitigates the settlement action for being pressurized and bringing, by distinguishing the secondary crushed rock filler set, green stone
Slag filler, limestone filler and lap slab of bridge（Lap slab of bridge, for the measure for preventing the sedimentation of bridge end coupling part and taking,
It can be rotated with the sedimentation banketed, vehicle can play cushioning effect when travelling, sedimentation of being banketed even if the platform back of the body is also unlikely to production
Life is uneven）, the settlement action that infiltration is brought can be mitigated, and lime stone is used, lime stone is produced expansion by water, by bridge
Beam attachment strap jack-up, also mitigates the effect of natural subsidence, is integrally used in conjunction with each other, and has reached prevention high fill road from many aspects
The advantage of base sedimentation.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 roadbed table top, 2 fill stratums, 3 broken stone piles, the short steelframe of 4 inner supports, the long steelframe of 5 inner supports, 6 permeable bottom plates, 7 two
Secondary crushed rock filler, 8 green stone slag fillers, 9 limestone fillers, 10 lap slab of bridge, 11 bridges.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, a kind of platform for preventing car jump between high road bed and bridge is carried on the back, including roadbed table top 1 and roadbed table top 1 one
The bridge 11 that side connects, the bottom of roadbed table top 1 is provided with fill stratum 2, and fill stratum 2 includes being taken with side bridge 11 for top
