Description
Technical field
It the utility model is related to road engineering technical field, specially a kind of asphalt concrete pavement for road surface drainage
Transverse notch structure.
Background technology
In the prior art, typically start with for China's Water Drainage of Expressway in terms of three：Roadbed transverse drainage, side slope row
Water, road surface drainage；Although drainage measure is more, but the problem of road surface drainage is not smooth occurs.For multilane at a high speed
Highway, particularly superelevation relax the ponding problem of changeover portion, are started with from subgrade and pavement drainage ditch mostly, spend big, effect
Difference；It is mostly that cement concrete pavement is set to increase road surface frictional resistance with more road surface groove structure now, not
The problem of considering road surface drainage.
With the fast development of economic construction of China, traffic volume of highway increases sharply, and incident is high-frequency friendship
The generation of interpreter's event.According to statistics, the traffic accident for having nearly a quarter is and the correlative study as caused by the factors such as misty rain wind and snow
Show, the degree of association of traffic accident and rain is bigger compared to other weather conditions degrees of association.Under rainstorm weather, rainfall is significantly
Beyond Pavement surface drainage ability, cause seeping phenomenon occur, reduce the frictional resistance of wheel and road, driving vehicle may be made
Water floats, and causes to lose control of one's vehicle, causes traffic accident, and consequence caused by the generation of such accident is mostly extremely serious.Especially exist
Autoroute superelevation runoff, road table resultant gradient is small, or even has at zero gradient, and draining runoff length is big, road table product
Water can not drain rapidly, and there is bend in the section in addition, if this section Vehicle Speed is fast, easily break away, and traffic thing occurs
Therefore.
Processing to easy ponding section, improved on original road mostly, such as change the profile of road gradient, road camber
Horizontal slope improves subgrade and pavement pumping equipment, and these measures can also improve road surface drainage performance to a certain extent, but during construction
The existing Coherent traffic noise time is grown, has a strong impact on traffic, and engineering cost is high.Road milling and grovving machine tool function admirable at present, road
Face cutting technology comparative maturity, to increase Anti-Sliding Performance of Cement Concrete Pavement, on newly-built cement concrete pavement
Through commonly used cutting technology, road surface cutting technology is applied on asphalt concrete pavement, can effectively improve superelevation mitigation
Road section surface ponding problem.
Utility model content
(1) technical problem solved
In view of the shortcomings of the prior art, it is horizontal to provide a kind of asphalt concrete pavement for road surface drainage for the utility model
To groove structure, the existing Coherent traffic noise time is grown when solving construction, has a strong impact on traffic, and the high problem of engineering cost.
(2) technical scheme
To realize object above, the utility model is achieved by the following technical programs：It is a kind of for road surface drainage
Asphalt concrete pavement Transverse notch structure, including roadbed body, road surface body is fixedly connected with the top of the roadbed body,
And the side of road surface bodies top is provided with median strip, the top of the road surface body and the one of centrally located dividing strip
Side is provided with track, and side of the track away from median strip is provided with curb, on the track and close to central strip
The side of band is provided with groove structure face, transverse groove is offered on the groove structure face, and set between two transverse grooves
There is road surface block, the top of the transverse groove cross section is provided with chamfering with the junction of road surface block.
Preferably, the transverse groove is in arranged in parallel, and transverse groove is arranged in a manner of equidistant.
Preferably, the bottom of the transverse groove inwall is inclined to set, and transverse groove is close to the side of median strip
Less than side of the transverse groove away from median strip.
Preferably, the track is unidirectional three lanes.
(3) beneficial effect
The utility model provides a kind of asphalt concrete pavement Transverse notch structure for road surface drainage.Possess following
Beneficial effect：This is used for the asphalt concrete pavement Transverse notch structure of road surface drainage, has simple structure, spy easy for construction
Point, using bituminous concrete Transverse notch structure, the noise that vehicle travels on traditional groove structure is reduced, increases road surface drainage
Ability；In autoroute, leftmost side runway is mainly that car is run at high speed track, load truck and other relatively low
Speed vehicle mainly travels on middle lane and rightmost side track；It is small that predominantly running at high speed for maximum is influenceed by surface gathered water
Automobile, to reduce damage effect of the heavy-duty vehicle to cutting asphalt concrete pavement, this technology is only carried out to leftmost side runway
Transverse notch, both solves the problems, such as surface gathered water, and and can is reduced because of the destroying infection of cutting road pavement.
