Description
Technical field
The utility model is related to roadbed field, filled-up ground on more particularly to a kind of subway line.
Background technology
The filled-up ground of Ordinary Rd, only need to carry out clear table to earth's surface, remove earth's surface debris, and substrate reaches that construction machinery grinds
After pressure request, so that it may which successively placement grinding shapes.For high-fill roadbed or soft soil roadbed, to avoid subgrade settlement excessive, city
City's subway is generally located on below town road, it is necessary to be adjusted to road elevation during existing town road transformation, is needed sometimes
1 ~ 5 meter is raised on the basis of original grade elevation, but subway tunnel structure is sensitive to top increment of load, can produce moderate finite deformation, shadow
Subway traffic safety is rung, therefore it is excessive to limit the increment of load on subway tunnel structure top.
Utility model content
The purpose of this utility model is to provide filled-up ground on a kind of subway line, and it can largely limit subway tunnel
The increment of load of structure upper is excessive.
Above-mentioned technical purpose of the present utility model technical scheme is that：Embankment on a kind of subway line
Dug on roadbed, including present situation pavement of road, the present situation pavement of road and filled out hole, the hole bottom of filling out is provided with medium coarse sand pad
Provided with EPS light fillers layer above layer, the medium coarse sand bed course, the EPS light fillers layer top is provided with reinforced concrete slab, described
Reinforced concrete slab is provided with new road surface structare layer away from EPS light fillers layer side.
By such scheme, dug on present situation pavement of road and fill out hole, medium coarse sand bed course is arranged on the bottom for filling out hole, can
The fastness of hole bottom is filled out in increase, and provided with EPS light fillers layer above medium coarse sand bed course, its filling that can either relatively stablize is filled out
Hole, it is light that material compares again, and larger increment of load will not be formed above subway, and reinforced concrete slab is arranged on EPS light fillers layer
Side, for compressing EPS light fillers layer, makes EPS light fillers layer relatively stablize, new road surface structare layer is arranged on reinforced concrete flaggy
Thus top, the stabilization that can compare just forms roadbed above subway line, and roadbed is by medium coarse sand bed course, EPS light fillers
Layer and reinforced concrete slab are constituted, and load is smaller, can largely be limited largely close to the deep native load of hole digging is filled out
Increment of load on subway tunnel structure top.
Further, the medium coarse sand cushion thickness is 30cm.
By such scheme, the bottom for filling out hole so can either be preferably reinforced, subway will not be influenceed due to blocked up again
The structural stability of roadbed above line.
Further, the reinforced concrete slab thickness is 15cm.
By such scheme, the compression EPS light fillers layer that reinforced concrete slab thick 15cm both can relatively stablize again can be compared with
Stable supports new road surface structare layer.
Further, the side of the medium coarse sand bed course towards EPS light fillers layer offers some grooves, the EPS
Light filler layer is extended with stiffener into groove.
By such scheme, open up fluted on medium coarse sand bed course, and EPS is extended with stiffener in groove, can
So that EPS light fillers layer largely combines with medium coarse sand bed course, so that EPS light fillers layer is relatively stablized.
Further, the both sides of the reinforced concrete slab are equipped with some fins, the EPS light fillers layer and new road surface knot
The stopper slot coordinated with fin is offered on structure layer.
By such scheme, such reinforced concrete slab will be by the fin of both sides while relatively stablizing with EPS light fillers layer
Combine, another side can with new road surface structare layer is relatively stable combines, make whole road structure more steady
It is fixed.
In summary, the utility model has the advantages that：
1st, the roadbed being made up of EPS light fillers layer, medium coarse sand bed course reinforced concrete flaggy and new road surface structare layer, both
Stability Analysis of Structures can be made, it is small that increment of load compares again；
2nd, by the cooperation of fin and stopper slot, whole roadbed can be allowed to be in relatively stable state.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Filled-up ground on a kind of subway line, as shown in figure 1, including present situation pavement of road 1, on present situation pavement of road 1
Dig and filled out hole 2.
As shown in figure 1, being equipped with medium coarse sand bed course 3 in the bottom for filling out hole 2, the thickness of medium coarse sand bed course 3 is 30cm, is laid on
The bottom that the bottom in hole 2 is used to strengthen filling out hole 2 is filled out, makes the bottom for filling out hole 2 more stable.
As illustrated in fig. 1 and 2, in half of the top of medium coarse sand bed course 3 provided with EPS light fillers 4, EPS of layer light fillers layer 4
Positioned at filling out in hole 2, second half, which is protruded, is filling out outside hole 2, for raising road surface, and in medium coarse sand bed course 3 towards EPS light fillers layer
4 side opens up fluted 31, and EPS light fillers layer 4 is extended with stiffener 41, stiffener 41 and EPS into groove 31
The one of light filler layer 4, is embedded in the groove 31 spacing to EPS light fillers layer 4, makes EPS light fillers layer 4 in relatively stablizing
State.
As shown in figure 1, being provided with reinforced concrete slab 5 in the top of EPS light fillers layer 4, the thickness of reinforced concrete slab 5 is 15cm, its
It is covered on EPS light fillers layer 4, for compressing EPS light fillers layer 4, EPS light fillers layer 4 is relatively stablized.
As shown in figs. 1 and 3, new road surface structare layer 6 is equipped with the top of reinforced concrete slab 5, while in the both sides of reinforced concrete slab 5
Some fins 51 are equipped with, and the limit coordinated with fin 51 is offered on EPS light fillers layer 4 and new road surface structare layer 6
Position groove 7, makes the fin 51 of the both sides of reinforced concrete slab 5 be embedded in corresponding stopper slot 7, is embedded the limit in EPS light fillers layer 4
Fin 51 in the groove 7 of position is spacing to reinforced concrete slab 5, reinforced concrete slab 5 is not easily touched, is embedded in new road surface structare layer
The new road surface structare layer 6 of 51 pairs of fin in 6 upper limit position grooves 7 is spacing, because reinforced concrete slab 5 is spacing by EPS light fillers layer 4, then
New road surface structare layer 6 is at the state relatively stablized, so that roadbed is in relatively stable state.
Additionally, due to being provided with filled-up ground, EPS light fillers 4, EPS of layer light fillers layer 4 is relatively light, but its structure ratio
Relatively stablize, the filling roadbed that both can have relatively stablized will not largely increase the load of roadbed, can largely connect again
Deep native load is dug in nearly hole 2 of filling out, and then largely limits the increment of load on subway tunnel structure top.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
