Description
Technical field
The utility model relates to highway technical field more particularly to a kind of anti-skid structures of express highway pavement.
Background technique
Highway belongs to high-grade highway, and highway refers to that " adapting to annual, the minibus volume of traffic is 25000 round the clock
Or more, specialize in the highway that automobile shunting runs at high speed and all controls discrepancy ".Various countries are although not to the name of highway
Together, but all referred exclusively to 4 lanes (including) more than, two to separate traveling, fully control entrance, all using crossings on different level
Highway.In addition, there is many countries public to part control entrance, the not all through main line using crossings on different level also referred to as high speed
Road.
Existing highway increases the frictional force of express highway pavement by opening up non-slip groove, prevents automobile from travelling
During, the phenomenon that having skidded, but non-slip groove can generate ponding on rainy day, while dust impurity is had in non-slip groove
Into non-slip groove, the obstruction of non-slip groove is caused, causes the skid resistance on road surface to decline, increases the probability of traffic accident.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of highway road proposed
The anti-skid structure in face.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of anti-skid structure of express highway pavement, including rammed earth layer are designed, rammed earth layer upper layer is equipped with rock layer,
It is equipped with microlith layer in the rock layer, anti-settling layer is equipped on the microlith layer, is equipped with reinforcement on the anti-settling layer
Layer, is equipped with concrete road surface on the enhancement layer, equidistant on the concrete road surface to offer multiple non-slip grooves, described anti-
Sliding slot bottom wall is provided with inclined surface, and the non-slip groove medium position is provided with and communicated with drainage hole, and the drainage hole is located at enhancement layer
Interior, the drainage hole lower end is connected with connecting tube, and the connecting tube both ends are provided with and communicated with gutter.
Preferably, the connecting tube semicircular in shape.
Preferably, between the non-slip groove between be divided into 2-3cm, the depth of the non-slip groove is 3mm-8mm.
Preferably, the concrete road surface, enhancement layer, anti-settling layer, microlith layer road surface thickness ratio be 2:1:1.4:
1.5, the thickness ratio of the rock layer and microlith layer is 5:2.
The utility model proposes a kind of express highway pavement anti-skid structure, beneficial effect is: non-slip groove, inclination
The design in face, drainage hole, connecting tube prevents ponding from influencing the frictional force on road surface, causes convenient for the ponding in non-slip groove to be discharged
Vehicle slip causes traffic accident, while under water flow and effect, convenient for the tiny stone in non-slip groove to be discharged, preventing
Only non-slip groove is blocked, and influences the antiskid effect of non-slip groove.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of express highway pavement anti-skid structure structural schematic diagram；
Fig. 2 be the utility model proposes a kind of express highway pavement anti-skid structure top view.
In figure: concrete road surface 1, enhancement layer 2, non-slip groove 3, drainage hole 4, connecting tube 5, gutter 6, rammed earth layer 7, anti-settling
Layer 8, microlith layer 9, rock layer 10, inclined surface 11 drop.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of anti-skid structure of express highway pavement, including rammed earth layer 7, rammed earth layer 7 is by rammer ramming
It is formed, 7 upper layer of rammed earth layer is equipped with rock layer 10, and rock layer 10 is laid with by stone, the formation under the rolling of road roller, stone
Microlith layer 9 is equipped on block layer 10, microlith layer 9 is laid with by microlith, then by formation under the rolling of road roller, on microlith layer 9
It is equipped with anti-settling layer 8, anti-settling layer 8 is poured by concrete and steel wire, and enhancement layer 2 is equipped on anti-settling layer 8, is added
Strong layer 2 is made of cement mortar, concrete road surface 1 is equipped on enhancement layer 2, the design of rock layer 10 and microlith layer 9 enhances
The structure of roadbed, prevents roadbed from settling, the design of anti-settling layer 8, prevents rock layer 10 and infiltration of the microlith layer 9 by water flow
Thoroughly, collapsing for rock layer 10 and microlith layer 9 is caused, the design of enhancement layer 2 enhances the intensity on road surface, prevents road surface from occurring broken
Damage.
It is equidistant on concrete road surface 1 to offer multiple non-slip grooves 3, between non-slip groove 3 between be divided into 2-3cm, non-slip groove 3
Depth be 3mm-8mm, 3 bottom wall of non-slip groove is provided with inclined surface 11, and 3 medium position of non-slip groove is provided with and communicated with drainage hole 4, row
Water hole 4 is located in enhancement layer 2, and 4 lower end of drainage hole is connected with connecting tube 5,5 semicircular in shape of connecting tube, the connection of 5 both ends of connecting tube
Be provided with gutter 6, concrete road surface 1, enhancement layer 2, anti-settling layer 8,9 road surface of microlith layer thickness ratio be 2:1:1.4:1.5,
The thickness ratio of rock layer 10 and microlith layer 9 is 5:2, plays anti-skidding effect by 3 road pavement of non-slip groove, when rainy day, is prevented
Ponding in sliding slot 3 can be discharged from drainage hole 4, be flowed into gutter 6 through connecting tube 5, prevent surface gathered water, cause road surface anti-
Sliding ability declines, while under the action of inclined surface 11 and water flow, and the stone in non-slip groove 3 can be taken away by water flow, prevent stone
Non-slip groove 3 is blocked, the decline of Pavement Skid Resistance ability is caused, causes traffic accident.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
