Technical field：
The utility model is related to a kind of permeable cover plate of road carbon fiber reinforced concrete, and in particular to a kind of steel plate-carbon fiber is mixed
Coagulate native permeable cover plate.
Background technology：
Under normal circumstances, in order to solve the problems, such as water on urban streets, we can set gutter in both sides of the road, will with this
Rainwater discharge on road.But drainage by open canal ditch can cause the nervous psychology of driver's trackside traveling, and wheel is once strayed into
Gutter can cause serious traffic accident.To solve the problems, such as to add in the open by design of open channel, urban road project
With macroporous gutter concrete cover, but current concrete cover guide water poor effect, it is easy to cause surface gathered water.
Normal concrete drainage ditch cover plate：Such a cover plate is at present using more, the macropore mainly by being reserved on cover plate
Hole reaches the purpose of draining, but such a cover plate be not it is continuous lay, progress draining at opening can only be found, easily cause on the contrary
The problem of making into ponding.In addition, macroscopic void is reserved to easily cause clogging, so it can more make road ponding problem more serious.
U-shaped resin drainage ditch cover plate：Structural stability is poor, and urban road both sides silt dust is very huge, and the time is slightly long,
Silt is largely blocked in the flowing water of centre seam, is resulted in blockage, it is necessary to timely manual cleaning, it is impossible to timely draining.
Conventional cover plate load-bearing is very low, it is impossible to undertake big load vehicle.Vertical and horizontal steel would generally be laid inside cover plate
Muscle, is formed framework of steel reinforcement, the bearing capacity of cover plate is improved with this.But, permeable cover plate is due to the long-term water penetration of itself, steel
Muscle is necessarily corroded by water, causes bearing capacity drastically to decline.For this phenomenon, it is replaced by seeking new material, this
New material is planted, it is both corrosion-resistant, there is higher bending tensile strength again.
Utility model content：
The purpose of this utility model is fine there is provided a kind of steel plate-carbon for above-mentioned problems of the prior art
Tie up concrete permeable cover plate, its is simple in construction, and water permeability is good, bearing capacity is strong, prevents road debris from dropping, pavement performance compared with
It is good.
To reach above-mentioned purpose, the utility model is realized using following technical scheme：
A kind of permeable cover plate of steel plate-carbon fiber reinforced concrete, including the load-bearing alloy-steel plate with groove structure and inlay

The utility model, which is further improved, is that shear connector is perforate screw thread peg.
The utility model, which is further improved, to be, the thickness ratio of permeable cover plate and load-bearing alloy-steel plate is 5:1.
The utility model has following technique effect：
The utility model used layering method, the pervious bed made with non-fine concrete and carbon fiber that upper strata is,
Lower floor is load-bearing alloy-steel plate, and the cover plate passes through the permeable hole draining in upper strata, there is good water penetration；Held with load-bearing alloy-steel plate
, can pressure-proof and snap-resistent, the pavement performance of raising drain bar by load.
In sleety weather, surface gathered water can be made rapidly to flow into gutter, a large amount of discharge path layers by osmosis
Surface area water.
Reduce ponding residual quantity, improve gutter service life.Due to itself having porous structure, it can lead in fine day
Cross and the ponding being retained in gutter is evaporated, prevent from oozing under ponding, ensure the durability of gutter.
Anti- folding can reach pavement performance requirement with compression strength, can increase road section space, improve the whole of road surface
Body width, the width that berths that keeps to the side of support vehicles.
Brief description of the drawings：
Fig. 1 is the longitudinal schematic cross-sectional view of overall structure of the present utility model；
Fig. 2 is the schematic top plan view of load-bearing alloy-steel plate.
Label is represented in figure：1- holes, 2- shear connectors, 3- carbon fibers, 4- load-bearing alloy-steel plates, the permeable cover plates of 5-,
6- through holes.
Embodiment：
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model embodiment is carried out it is clear,
It is fully described by.
As depicted in figs. 1 and 2, a kind of permeable cover plate of steel plate-carbon fiber reinforced concrete that the utility model is provided, including with
The load-bearing alloy-steel plate 4 of groove structure and the permeable cover plate 5 being embedded in the groove structure of load-bearing alloy-steel plate 4.Wherein, load-bearing
The bottom of the groove structure of alloy-steel plate 4 offers through hole 6, and permeable cover plate 5 is made of concrete and carbon fiber 3, and permeable lid
Multiple holes 1 are distributed with plate 5.
Permeable cover plate 5 is carbon fiber reinforced concrete, is made of concrete and carbon fiber 3, and is distributed on permeable cover plate 5
There are multiple holes 1, current can reach carbon fiber reinforced concrete from the permeable top of cover plate 5 through the hole 1 of carbon fiber reinforced concrete
The bottom of structure.
The bottom of the groove structure of load-bearing alloy-steel plate 4 offers through hole 6, and through hole 6 is rectangular through holes, mixed from carbon fiber
Thus hole flows into gutter to the water flowed down in Xtah Crude Clay structure.
Traditional drainage ditch cover plate there are problems in it, be that this mentality of designing of the present utility model is good water permeability, letter
Singly, pavement performance is good and cost is low.In road technology field, cost often causes significant impact to the practical application of product.
Therefore, this drainage ditch cover plate of the present apparatus, is integrally divided into two big layers, there is hole 1 in the permeable cover plate 5 on upper strata.Hole 1
Effect be water conservancy diversion, it between distribution be vertically distributed or mixed and disorderly, hole 1 can be phase that hole 1 therein, which can be,
Intercommunicated can also be disconnected, but the hole 1 to be protected will provide the passage lanes of current from this layer from top to bottom, make current
Cover plate can be passed through.
By a large amount of design experiments, when the aperture of the permeable mesopore 1 of cover plate 5 of the utility model is 50~300nm, whole lid
The performance of plate is optimal.On the thickness of permeable cover plate, the size of hole 1 and the influence of the Rotating fields intensity should be considered, again
Meet overall permeability rate to require, the thickness control of cover plate is in 100mm or so.For the size of the permeable monnolithic case of cover plate 5
It is required that, when permeable 5 generally rectangular parallelepiped structure of cover plate, the overall dimensions of permeable cover plate 5 for length × width × height=400mm ×
250mm × 100mm is optimal.
In order to which the permeable cover plate 5 to upper strata carries out effective support, to lift the pavement performance of whole drainage ditch cover plate, this
Utility model is provided with the load-bearing alloy-steel plate 4 of lower floor, and load-bearing alloy-steel plate 4 includes the alloy sheets of a resistance to raindrop erosion, closes
There are through hole rectangular through holes on golden steel plate.
The side of permeable cover plate 5 is fixed together by shear connector 2 with load-bearing alloy-steel plate 4, shear connections
Part 2 is connected with the contact site of load-bearing alloy-steel plate 4 using melting welding mode, and shear connector 2 is perforate screw thread peg.
