Technical field
The utility model relates to a kind of cement concrete pavement, especially relates to a kind of antiskid cement concrete pavement.
Background technology
Cement concrete pavement because it has that intensity is high, good stability, long service life and the advantage such as maintenance costs is low, therefore be widely used in the highway construction of China.But compare with flexible pavement, its surperficial anti-slide performance is lower, its application in speedway of having driven a vehicle the restless drawbacks limit such as large.
The cornering ratio of highway pavement is larger, and cling property is just better, and the braking distance of vehicle when brake is just shorter.Existing highway pavement mainly is divided into two kinds of flexible pavement and cement concrete pavements, and the cornering ratio of flexible pavement is larger, therefore is widely used in expressway construction; Cement concrete pavement is if do not processed, and its anti-slide performance is starkly lower than the anti-slide performance of flexible pavement, and for improving the anti-slide performance of cement concrete pavement, usual way is to carry out cutting on cement concrete pavement.
Existing cement-concrete road-surface groove-carving mainly adopts horizontal and vertical two kinds of cutting forms, and transverse groove and cannelure are straight trough, transverse groove can be good at increasing the longitudinal frictional force on road surface, but direction is controlled poor, vehicle easily causes vehicle that skew occurs and causes accident when brake hard; Cannelure can improve the direction of driving to be controlled, and effectively reduces driving accident, but little for increasing the longitudinal frictional force effect.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of antiskid cement concrete pavement is provided, it is simple in structure, reasonable in design and cling property is good, the problem of water-setting rigid pavement vertical straight trough anti-slide performance deficiency that adopted annular cutting mode to solve on the one hand, solved on the other hand horizontal straight trough vehicle the problem of breakking away easily occurred when brake hard.
For achieving the above object, the technical solution adopted in the utility model is: a kind of antiskid cement concrete pavement, it is characterized in that: comprise cement concrete pavement, be carved with anti-slip veins on the surface of described cement concrete pavement, the quantity of described anti-slip veins is many, many described anti-slip veins is evenly laid and is parallel to each other, described anti-slip veins is comprised of a plurality of cannelures that are connected, the inner circle of adjacent two described cannelures is tangent, the exradius of described cannelure is 15mm～20mm, the interior radius of circle of described cannelure is 10mm～15mm, the groove depth of described cannelure is 3mm～5mm, beeline L between the cannelure of adjacent two described anti-slip veins is 2mm～4mm.
Above-mentioned a kind of antiskid cement concrete pavement is characterized in that: many described anti-slip veins are all laid along the bearing of trend of cement concrete pavement.
Above-mentioned a kind of antiskid cement concrete pavement is characterized in that: many described anti-slip veins are all laid along the direction vertical with the cement concrete pavement bearing of trend.
Above-mentioned a kind of antiskid cement concrete pavement is characterized in that: the exradius of described cannelure is 17.5mm.
Above-mentioned a kind of antiskid cement concrete pavement is characterized in that: the interior radius of circle of described cannelure is 12.5mm.

Above-mentioned a kind of antiskid cement concrete pavement is characterized in that: the beeline L between the cannelure of adjacent two described anti-slip veins is 3mm.
The utility model compared with prior art has the following advantages:
1, the utility model is simple in structure, reasonable in design and cling property is good.
2, the utility model problem of water-setting rigid pavement vertical straight trough anti-slide performance deficiency that adopted annular cutting mode to solve on the one hand, solved on the other hand horizontal straight trough vehicle the problem of breakking away easily occurred when brake hard.
3, the utility model is compared with traditional straight trough cement concrete pavement, has greatly increased the surface texture of cement concrete pavement, thereby the frictional force on while making vehicle brake and road surface increases, and reduces braking distance, and the antiskid effect is more obvious.
4, the utility model can increase longitudinal frictional force in the horizontal, can play in the vertical the restriction vehicle when car brakeing the effect of breakking away occurs, and guarantees traffic safety.
5, the utility model acts on particularly outstandingly on bend, can increase the frictional force in when brake, shortens braking distance, can improve again the lateral stability of driving, and unlikely vehicle occurs to break away and cause traffic accident.
6, can play good cushioning effect when the utility model and vehicle collision, reduce the impact force of road pavement cutting, reduce road surface cutting wearing and tearing, extend the application life of cement concrete pavement.
Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment
Embodiment 1
As shown in Figure 1, a kind of antiskid cement concrete pavement, comprise cement concrete pavement 1, be carved with anti-slip veins on the surface of described cement concrete pavement 1, the quantity of described anti-slip veins is many, many described anti-slip veins is evenly laid and is parallel to each other, and described anti-slip veins is comprised of a plurality of cannelures that are connected 2, and the inner circle of adjacent two described cannelures 2 is tangent; The exradius of described cannelure 2 is 15mm～20mm, and the interior radius of circle of described cannelure 2 is 10mm～15mm, and the groove depth of described cannelure 2 is 3mm～5mm, and the beeline L between the cannelure 2 of adjacent two described anti-slip veins is 2mm～4mm.
In the present embodiment, many described anti-slip veins are all laid along the direction vertical with cement concrete pavement 1 bearing of trend.
In the present embodiment, for the ease of saving the engineering time, can play again obvious antiskid effect, the exradius of described cannelure 2 is 17.5mm, and the interior radius of circle of described cannelure 2 is 12.5mm simultaneously.
In the present embodiment, the degree of depth of described cannelure 2 is 4mm, and antiskid is effective.
In the present embodiment, the beeline L between the cannelure 2 of adjacent two described anti-slip veins is 3mm, not only be convenient to many anti-slip veins and construct simultaneously, and antiskid is effective.
The present embodiment by carving the cannelure anti-slip veins on the surface of cement concrete pavement 1, form cannelure anti-slip veins cement concrete pavement, with traditional straight trough anti-slip veins cement concrete pavement, compare like this, greatly increased the surface texture of cement concrete pavement, thereby the frictional force on while making vehicle brake and road surface increases, reduce braking distance, the antiskid effect is more obvious.Concrete, can increase longitudinal frictional force in the horizontal, can play in the vertical the restriction vehicle when car brakeing the effect of breakking away occurs, guarantee traffic safety; On bend, effect is particularly outstanding, can increase the frictional force in when brake, shortens braking distance, can improve again the lateral stability of driving, and unlikely generation is breakked away and caused traffic accident.In addition, with vehicle collision the time, can play good cushioning effect, reduce the impact force of road pavement cutting, reduce road surface cutting wearing and tearing, extend the application life of cement concrete pavement.
