The present invention relates to a roadway roadway having a road block in which the drainage is smoothly formed. When road drainage is not smooth on asphalt pavements and concrete pavements, rainwater accumulates on the pavement roads, thereby forming a so-called water film. If the water film is formed in this way, the braking performance of the vehicle may be deteriorated, which may cause slippage or an accident due to reflection of the headlight. Accordingly, it is common to provide a road drainage system for preventing rain water from accumulating on the pavement.

The conventional drainage asphalt pavement is composed of an auxiliary base layer stacked on the roadbed, a base layer stacked on the auxiliary base layer, an intermediate layer stacked on the base layer, and a surface layer stacked on the intermediate layer. In such a laminated structure, the intermediate layer may not be laminated or the in-phase preventing layer may be laminated in the middle, and in the case of simple packaging, the base layer may be excluded from the laminated structure.

The surface layer leads to drainage where the rainwater flows over the surface layer when rainwater is placed on the road surface.

However, the surface layer has a large amount of rainwater is stacked on the surface layer to move up to the drainage, which is difficult to immediately drain, the drainage rate is significantly reduced, if the road itself is severely curved up and down, the water is accumulated in the concave part and drainage smoothly There was a problem that does not.

The present invention has been invented to solve the above problems, regardless of the amount of rain water, the drainage of the roadway at high speed, particularly absorbed to drain the water accumulated in the concave part due to the curvature of the roadway at high speed The object is to provide a roadway drawing with a roadblock formed with balls.

The present invention for achieving the above object is an auxiliary base layer composed of a ground layer, a soil layer in which a stable or unstable granular material is stabilized as a voltage or an appropriate mixed material and stacked on top of the furnace, and an auxiliary base layer. A roadway drawing having a surface layer laminated on top to distribute a load of a vehicle, comprising: a drain pipe installed between the auxiliary base layer and the surface layer of the roadway drawing; A water collecting mechanism is provided with a pipe-shaped guide portion communicating with the drain pipe, a drain hole penetrating the lower circumferential surface of the guide portion, and an inflow portion enlarged in diameter on the upper portion of the guide portion and opened out of the road surface.

And a surface layer 15 which is stacked on top of the auxiliary base layer 12 and distributes the load of the vehicle, wherein the drain pipe is installed between the auxiliary base layer 12 and the surface layer 15 of the vehicle road drawing ( 20) and; A guide portion 32 in the form of a tube communicating with the drain pipe 20, a drain hole 33 penetrating through the lower circumferential surface of the guide portion 32, and an enlarged diameter in the upper portion of the guide portion 32 and opened out of the road surface. The water collecting mechanism 30 having the inlet portion 31 to be reinforced is reinforced.

In the present exemplary embodiment, the roadway drawing 10 is formed by sequentially stacking a roadbed 11, an auxiliary base layer 12, a base layer 13, an intermediate layer 14, and a surface layer 15 from the ground.

The hearth 11 finally supports all the loads acting on the pavement as the basis of the roadway drawing. The hearth 11 should be able to provide a support condition that does not cause excessive strain or displacement due to stress transmitted through the upper roadway 10 of the multi-layer structure. In addition, by forming a certain thickness of the upper portion of the hearth 11 in one layer to prevent the installation of an frostbite prevention layer (not shown) to mitigate the effect of the freezing action or to intrude into the fine-grained soil auxiliary layer 12 of the hearth (11). In order to provide a barrier layer (not shown).

The auxiliary base layer 12 is laminated on the hearth 11. The subsidiary base layer 12 is composed of a soil layer which has been stabilized or unstable granular material which has been stabilized as a voltage or proper mixed material. Generally used crushed stone, slug, crushed sand, or aggregates thereof, and stabilized admixtures such as portland cement, asphalt, lime, cement fly ash, lime fly ash, and the like may be used. The auxiliary base layer 12 is located in the middle of the surface layer and the roadbed 11 together with the base layer 13, and distributes the traffic loads transmitted through the surface layer 15 and the base layer 13 to the roadbed 11. Do it. In addition, the auxiliary base layer 12 functions to prevent fine grains in subgrade soil from invading the base layer 13 and to minimize damage caused by freezing.

The base layer 13 refers to a layer which is stacked on the auxiliary base layer 12 and disposed below the surface layer 15 to be installed for the purpose of structural support of the asphalt pavement. In the base layer 13, methods such as particle size adjustment, cement stabilization treatment, bitumen stabilization treatment, and penetration type are used.

The intermediate layer 14 is mainly provided between the base layer 13 and the surface layer 15 when the base layer 13 is treated with a cement stabilizer treatment layer, thereby correcting the irregularities of the base layer 13 and applying the surface layer 15 to the surface layer 15. It functions to evenly transmit the load to the base layer 13. In addition, when using the permeable surface layer 15 as in the present invention, it is also possible to use a layer that blocks water.

The surface layer 15 is located at the top of the pavement, and serves to resist the wear and shear caused by the traffic vehicle and to prevent the sliding of the vehicle with the dynamic function of distributing the traffic load to the lower layer.

The surface layer 15 may form a permeable surface layer 15 using porous asphalt or concrete, thereby allowing rainwater placed on the road surface of the surface layer 15 to be absorbed into the surface layer 15.

The drainage pipe 20 is embedded between the intermediate layer 14 and the surface layer 15, crossing the roadway surface 10 in the form of a pipe, and an end thereof is connected to the sewer pipe 41.

The water collecting mechanism 30 includes a guide part 32, a drain hole 33 formed on an outer circumferential surface of the guide part 32, and an inlet part 31 provided at an upper part of the guide part 32.

The guide part 32 penetrates the upper part of the drain pipe 20, is located in the vertical direction, is fixed to the surface layer 15, and the upper and lower parts thereof are opened.

The drain 33 is formed to penetrate through the outer circumference of the guide portion 32, the rain water guided from the guide portion 32 is in communication with the drain pipe 20 to communicate with the drain pipe (20).

The inlet portion 31 is enlarged in diameter so as to communicate with the guide portion 32, it is seated on the surface layer 15, the rain water flowing through the surface layer 15 is collected.
