Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a road heating drainage structure for melting and discharging ice and snow on a road surface.

[0002]

[Prior Art]

 In recent years, the importance of roads has increased with the development of automobiles, and many roads have been constructed.However, especially in cold regions, snowfall in winter causes the road surface to freeze, which may lead to danger of driving and impassability. In many cases, its function is not exerted.

Currently, as methods for preventing snow accumulation and freezing on major roads, mechanical snow removal, snow melting with cold materials such as calcium chloride, snow melting with electric heat, snow melting with groundwater, etc. are carried out. Although there are merits and demerits, snow melting due to electric heat is often used especially on slopes. Road heating, which uses electric heat to melt snow, embeds a heating wire for heating in a meandering shape at a certain depth from the road paving surface, and conducts electricity to this heating wire to transfer heat to the surrounding pavement material to cover snow. And to prevent freezing.

FIG. 3 shows the flow of snow-melting water by road heating on a slope 1 to an outlet 2 provided on the sidewalk under the slope. In FIG. 4, a drainage duct 3 is provided under the slope so as to cross the road. The figure shows a state in which the steel plate 4 made of expanded metal or the like is covered thereover to discharge the snowmelt water.

[0005]

[Problems to be solved by the device]

 However, in FIG. 3, due to the slope of the road surface, only a part of the snowmelt water flows into the discharge port 1, and most of it flows under the hill and is mixed with the snow under the hill and remains in a sherbet shape. This sorbet-shaped snowmelt water is brought back to the slope 1 by the vehicle, and the road surface is always in a wet state, and the power consumption increases. If the temperature drops in such a condition, the snowmelt water brought in may freeze again and may interfere with the running of the vehicle.

Further, as shown in FIG. 4, the drainage duct 3 provided below the slope is effective for drainage, but the steel plate 4 generates noise, which causes deformation and drainage when the vehicle is traveling a lot. There is a problem that it will come off the duct 3 and hinder driving.

An object of the present invention is to solve the above-mentioned problems, to provide a drainage structure of road heating which is efficient and has excellent strength, which completely discharges snowmelt water and does not hinder the running of a vehicle. .

[0008]

[Means for Solving the Problems]

 The drainage structure for road heating according to the present invention to achieve the above-mentioned object is a drainage structure for road heating in which a slope is road-heated and a drainage groove is provided under the slope. The pavement is characterized by being provided with a heater and a heater provided below the water-permeable pavement.

[0009]

[Action]

 In the road heating drainage structure with the above configuration, since the upper surface of the drainage ditch is permeable to pavement, snowmelt water on the road surface is discharged without remaining, and there is no obstacle such as noise.

[0010]

【Example】

 The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a schematic view of a road surface to which this embodiment is applied, and FIG. 2 is a sectional view taken along the line AA. Road heating is applied to the slope 11 of the road, and the road surface under the slope 12 is a water-permeable pavement 13 having a width of, for example, 30 to 40 cm so as to cross the road. The water-permeable pavement 13 is made of interlocking blocks or water-permeable asphalt that is spread at intervals, and a curb 14 is provided on the road side. A drain groove 15 is provided below the water-permeable pavement 13, and the upper surface thereof is covered with a porous lid 16. The lid 16 is made of a material having high strength, for example, glass wool is pressed, or glass wool is sandwiched between porous concrete plates. A heating wire 17 for heating is laid on the upper surface of the lid 16.

In such a structure, the water melted by the road heating and flowing down the slope 11 is collected on the slope 12 and permeates the water-permeable pavement 13. The permeated water passes through the porous lid 16, falls into the drainage groove 15, and is discharged into the sewer as shown by the arrow.

As described above, in this embodiment, the snowmelt water that has permeated from the road surface provided with the water-permeable pavement 13 is heated by the heating wire 17 and does not freeze, so that the electric power also heats a small amount of the snowmelt water. Only minutes are needed. Further, since the water-permeable pavement material is used in place of the steel plate 4, no noise is generated and the drain groove 15 is not exposed due to damage.

[0013]

[Effect of the device]

 As described above, the drainage structure of the road heating according to the present invention is provided with a drainage groove across the road under the slope of a road with a road heating, and a water-permeable pavement with a heater is provided on the upper surface thereof. Therefore, the snowmelt water flowing down the slope penetrates under the road surface and drains without icing.
