Abstract

<P>PROBLEM TO BE SOLVED: To provide a method of economically maintaining a road surface in a safe state while exerting a convenient function of a draining pavement in a circumstances that various snow melting devices contrived in recent years do not pay in terms of cost efficiency when the number of snowing days or the number of road freezing days per year is taken into consideration in some areas. <P>SOLUTION: A steel pipe having pores formed therein is arranged under the draining pavement, and when road freezing is expected, air is blown from the pipe. The air blown from the pipe passes through the coarse portion of the draining pavement and reaches the road surface. The air serving as a medium is taken into the pipe via an exhaust hole of a tunnel when the location is set at a bridge, a road, etc. near the tunnel. When the tunnel etc. are not present near the location, the air is secured by feeding compressed air into the pipe by a compressor. The air fed to the pipe has a temperature as high as possible so as to dry the road surface, and snow melting or freezing prevention is achieved. An installation time and trouble are saved by unitizing a pipe installation portion, and an installation cost and an environmental load are reduced by forming a unit of the pipe installation portion of recycled materials such as reclaimed crushed stones. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to the prevention of snow melting and freezing on roads in order to save equipment costs and management costs.

  In recent years, drainage asphalt pavement has become the mainstream in order to improve the running performance of vehicles traveling on the road in rainy weather or to reduce the noise when the road surface is dry. The present invention makes use of the roughness of this drainage pavement, pipes with a large number of small air holes under the pavement, and spraying warm gas from the holes to warm or dry the road surface. To prevent freezing and snow accumulation. In addition, by making the equipment into units in advance, it is possible to reduce the cost by omitting the installation work.

  In the watering method in which water is applied to the road surface, water cannot always be supplied near a road where a snow melting / freezing prevention system is required. Even if groundwater is adopted, problems such as land subsidence, long-distance piping costs to draw water, and pump costs are required.

  In the method of installing a heater such as an electric heating facility on the road surface, a large amount of cost is required for the facility cost and installation cost of the heater, and the running cost after the start of operation becomes even larger. For this reason, it can be used only on a part of the road such as a tunnel exit in a mountainous area or a short bridge portion, and it causes a danger in reverse of the running of the vehicle.

A method using geothermal energy can also be seen, but when this is put into one of the proposals, the first question is whether geothermal heat can be secured in the corresponding location, which requires investigation. There is also a method of laying pipes that are closed deep in the ground and circulating the liquid in them, but this also costs installation costs similar to watering and electric heating. As with the electric heating system, it is often used partially on the road.

  The problem to be solved is to avoid a huge investment to prepare for road freezing and snowfall of several days in the mountainous area of Sanin and Western Japan, etc., and to achieve higher safety driving with less investment It is.

  The present invention is characterized in that a snow melting system and an anti-freezing system for a paved road surface are established by installing a unit for jetting gas on the road surface.

  As described above, according to the present invention, the medium is a gas and can be obtained anywhere as long as it is on the ground. The cost of the facility will be low, with only the cost of air supply and jetting and the cost of the compressor, and combined use with drainage pavement in regions where the number of freezing and snowfall on the road surface is small can be expected to have a high investment effect.

  By jetting a gas having a temperature higher than the outside air onto the road surface, the wetness of the road surface leading to freezing can be dried.

  Moreover, equipment costs can be reduced by unitizing equipment.

  Cost and environmental burden can be reduced by using recycled crushed stone, etc., which is generated in abundance as a unitized medium.

  An embodiment of the present invention is shown in FIG.

  FIG. 1 is a cross-sectional view of an embodiment of the apparatus according to the present invention. A road pavement surface 1 is a drainage pavement, and a pipe unit 3 is installed at the lower part of this 1 to send air to the unit and eject it. The piping 2 for this is provided in the suitable space | interval.

  The pipe 2 is provided with a large number of holes 4 for ejecting air.
