BRIEF SUMMARY
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention is related to providing a raised pavement marking apparatus for installing on a high level road a curve road, or an uphill road with a heavy snowfall.
(2) Description of the Prior Art
It has been well known in the art that the raised pavement marking device has the function for reflecting the light of the head light in order to represent the central line, getting over the driver's sleepy spell and showing the central line during it is raining or snowing. The conventional raised pavement marking device has been installed by way of striking it into the road or by using the adhesive agent, but even though a little amount of snow has been fell, the raised pavement marking device is invisible before the snow is melted or removed therefrom. Furthermore, since a snowplow cars or equipments must be mobilized to clear the pavement of snow, the traffic will be brought to a standstill for a moment. When a thawing chemical agent is used to melt the snow, it is a number of problems such as, for example, a supplementary budget is required as well as various road safety facilities, for example a guard rail, a street light and a traffic safety sign, installed on the road, and the car body are corroded and broken due to the agent.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a raised pavement marking apparatus for melting and/or drying the snow or the rain.
The other object of the present invention is to provide a method for installing a raised pavement marking apparatus.
The present invention comprises the raised pavement marking apparatus including a duct pipe laid horizontally or vertically in the predetermined arrangement under the subbase course of the ground, a vertical connection pipe communicated by way of a nozzle with the cavity of the raised pavement marking device and a horizontal connection pipe inserted in the duct pipe and having numerous drain pipe and at least one air heater and compressor installed on the predetermined position, a raised pavement marking fixing hole formed in the surface course and the base course, a precast concrete block for fixing the vertical connection pipe and raised pavement marking device inserted in said fixing hole, at least one reflector mounted on its slant surface, a cavity formed in its central portion, a plurality of jet holes formed radially around it's periphery, which is communicated with the cavity, and a fixing pin for supporting the raised pavement marking device which is inserted into the fixing hole.
Therefore, the marking device of the present invention comprises the air pipe laid under the ground of the road, the air nozzle mounted on the front end of the connection pipe connected to the air pipe and communicated with the cavity of the raised pavement marking fixed on the surface of the road, whereby the heated air supplied through the air pipe is jetted out of the road surface through the nozzle and the raised pavement marking device can easily melt the snow piled on the road surface and also to remove the moisture therefrom, so that the road surface is always kept in the drying state in order to help the smooth travel of the vehicles.
BRIEF DESCRIPTION OF DRAWINGS
The above and other objects of the present invention will be seen by the following description taken in connection with the accompany drawings, in which:
