Background technology
Culvert belongs to buried structures, and current one kind for being referred to as " lifeline engineering " in the world.It is in traffic, water
The many departments such as profit, railway, mine, electric power, municipal administration, oil, military project are widely used.It is fast with China Higher level highway construction
Hail exhibition, stress, sedimentation and the problem of Cracking of culvert have caused the common concern of engineers and technicians under high-filled subgrade.Due to existing
Row highway bridge and culvert design manual and Earth Pressure, culvert design standard drawing about providing or recommending in specification, code
And its construction method, fail to account properly for, handle and calculate soil pressure and its deformation of High Earth-Filled Culvert, so that generally drawing
Culvert cracking and excessive differential settlement are played, therefore has saying for " ten, which contain nine, splitting ", these diseases gently then cause culvert cracking, seepage
Or ponding, it is heavy then cause culvert structure to destroy, or even collapse, have a strong impact on the normal use of road.
Utility model content
In order to solve the above problems, the purpose of this utility model is that providing a kind of good high-filled subgrade culvert of stability subtracts
Lotus structure.
To achieve these goals, the technical solution adopted in the utility model is：A kind of high-filled subgrade culvert off-loading structure,
Including ground, the culvert being arranged on ground, the fill stratum of above culvert and both sides is arranged on, the culvert upper surface is provided with
EPS off-loading layers, the EPS off-loadings layer are made up of at least one piece of EPS sheet, and the culvert both sides are equipped with multiple stake holes, the stake
The those widened sections in hole including upper end and the normal portion of lower end, the those widened sections and normal portion are cylinder, the those widened sections it is straight
Footpath is more than the diameter in normal portion, and being filled in the stake holes has epoxy resin mortar, and the upper surface of the stake holes is less than fill stratum
Upper surface, and higher than the upper surface of culvert.
A kind of high-filled subgrade culvert off-loading structure as described above, further illustrates to be that the thickness of the EPS off-loadings layer is
15~30cm.
A kind of high-filled subgrade culvert off-loading structure as described above, further illustrates to be that the culvert both sides are respectively set
There is EPS sheet.
A kind of high-filled subgrade culvert off-loading structure as described above, further illustrates and is, the EPS off-loadings layer upper surface with
Steel modeling grid is provided between fill stratum.
A kind of high-filled subgrade culvert off-loading structure as described above, further illustrate to be that the upper surface in the normal portion is high
In the upper surface of culvert, the normal portion bottom is extended in ground.
The beneficial effects of the utility model are：1st, by setting EPS off-loading layers to greatly reduce the vertical pressure above culvert
Power, alleviate the culvert load under High-filled emkankment, ensure that culvert can long-term normal operation, further in culvert both sides
EPS sheet is set, the horizontal pressure force of culvert both sides can be reduced, extends the service life of the culvert.2nd, by setting multiple stakes
Hole, stake holes is up big and down small, beneficial to soil arch is formed in embankment, so as to be transferred to beneficial to by embankment at the top of stake holes, reduces culvert
While hole loads, beneficial to the stability for reducing Embankment Subsidence, improving roadbed.

Embodiment
The utility model embodiment is further elaborated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of high-filled subgrade culvert off-loading structure that the present embodiment provides, including ground 1, it is arranged on ground
Culvert 2 on 1, the fill stratum 3 of the top of culvert 2 and both sides is arranged on, the upper surface of culvert 2 is provided with EPS off-loadings layer 4, described
EPS off-loadings layer 4 is made up of at least one piece of EPS sheet, and the EPS sheet is also referred to as expandable polystyrene plate, the EPS sheet have it is light,
It is excellent that inexpensive, low thermal conductivity, water imbibition are small, electrical insulation capability is good, sound insulation, shockproof, moistureproof, moulding process are simple etc., not right here
EPS sheet elaborates, and by setting EPS off-loadings layer 4 to greatly reduce the pressure at right angle above culvert, alleviates High-filled emkankment
Under culvert load, ensure that culvert can long-term normal operation, preferably, the thickness of the EPS off-loadings layer be 15
~30cm.
In order to the both sides of culvert 2 carry out off-loading, can also the both sides of culvert 2 be respectively provided with EPS sheet, so as to subtract
The horizontal pressure force of few both sides of culvert 2, extend the service life of the culvert.Further, can also be on the EPS off-loadings layer 4
Steel modeling grid 6 is provided between end face and fill stratum 3, can be further to being applied to EPS off-loadings layer 4 by setting steel to mould grid 6
On pressure at right angle divided, so as to avoid destruction of certain pressure to EPS off-loadings layer 4, while by setting steel to mould lattice
Grid 6 can prevent with delayed reflex crack, while and can increase structural strength.
