Abstract

PURPOSE: To conduct traffic marking while laying a snow-melting block by mounting a colored layer on concrete in proper thickness on the top face of a block body, in which a water conveyance pipe and a spray nozzle body are unified by concrete. CONSTITUTION: A water conveyance pipe 1 and spray nozzles 2 connected to the water conveyance pipe 1 at proper intervals are unified by a concrete body 3 under the state, in which the top face sections of the spray nozzles 2 are exposed, while a placing receiving section 5 and a rear section 6 are installed at the end sections of the concrete body 3 respectively. A colored layer 7 in proper thickness is set up on the top face section of the concrete body 3, thus forming a snow melting block A. The water conveyance pipe 1 of a connected snow melting block A0 is coupled with the placing receiving section 5 of the snow-melting block A by a socket body at the time of the execution of works.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow-dissipating block installed on a road in order to melt snow on the road surface by sprinkling water.

[0002]

2. Description of the Related Art Generally, a snow-melting road that melts snow on the road surface is provided with a groove at the center of the road, a water supply pipe is arranged at the bottom of the groove, and water spray nozzles connected to the water supply pipe are arranged at appropriate intervals. After that, concrete was placed in the groove so that the sprinkling port (upper surface portion) of the sprinkling nozzle was exposed to the road surface. However, since the above construction will worsen road traffic conditions, in order to shorten the construction period, prepare a snow-melting block that integrates the water supply pipe to be buried in the ditch and the water spray nozzle with concrete etc. in advance. It is known that the blocks are buried in a groove dug on the road and the blocks are connected to form a snow-melting road (Act No. 55-1).

[Problems to be Solved by the Invention] By the way, the road display management such as the center line is basically managed by the Public Safety Commission (police), not by the local public body which manages the construction of snow-covered roads. , The road is removed from the display. However, the road marking, that is, the center line, which is normally separated from the oncoming lane, is located at the center of the road, and it is convenient to sprinkle water from the center of the road in consideration of the effect of snow removal. Furthermore, if a snow-making block made of concrete is laid in the center of the asphalt road, it may be confused with the road display especially at night. Therefore, a new snow-melting block that can solve the above problems is proposed.

[0004]

According to the present invention, there is provided a snow removal block for a snow removal road, wherein a water pipe and a water spray nozzle connected to the water pipe at appropriate intervals are made of concrete into a rod-shaped integrated block body. In the block that connects the water pipes of the above to construct a snow-melting road, the concrete layer with an appropriate thickness on the upper surface of the block body is provided with a colored layer in which a pigment with a color corresponding to the road color or the road surface color is mixed. It is a feature.

[0005]

[Operation] When a snow-melting block is exposed on the road surface and the water pipes are sequentially connected and buried to construct a snow-melting road, and when the upper surface of the block is a colored layer with the same color as the road display Can also serve as a road display, and in the case of a colored layer having the same color as the road surface color, only the upper surface of the water spray nozzle body is visible and the block body is not confused with the road display.

[0006]

EXAMPLES Next, examples of the present invention will be described. The snow-melting block shown in the embodiment is basically similar to the conventional one, and a water pipe 1 penetrating through the block A, and a water spray nozzle 2 connected to the water pipe 1 at appropriate intervals, It is composed of a concrete body 3 that exposes the upper surface portion (water spouting portion) of the water sprinkling nozzle and integrates these into a rod shape, and a reinforcing bar 4 for reinforcing the concrete body 3, and is mounted on each end of the block body. The receiving part 5 and the gouging part 6 are provided, and in particular, the colored layer 7 is provided on the upper surface portion of the concrete body 3.

The colored layer 7 is a concrete (colored layer) obtained by mixing 2 to 3% by weight of an inorganic pigment of a predetermined color with a concrete body 3 whose upper surface is slightly lower in advance when forming a block. It is provided by filling in a mold and solidifying concrete. The color shall be yellow when used for road marking and black when used for asphalt road surface.

In order to install the snow-melting blocks A and A0 provided with the yellow color layer 7 on the road surface B, a groove C is dug at the road display position on the road surface B, and a crushed stone D is placed in the groove. The snow-melting blocks A are arranged one after another by laying down the snow-melting blocks A, and the snow-absorbing blocks A are mounted on the mount receiving portion 5 of the snow-melting block A. Both blocks A, A0
The water pipe 1 is connected with an appropriate connecting device or a socket body provided at the end of the water pipe in advance, and then the gap in the groove is filled with sand E or mortar, asphalt, concrete, etc. Is covered with asphalt, concrete or the like to integrate the snow-melting blocks A and A0 with the road surface.

Therefore, a line of the snow-melting block is formed on the road surface, but since this line is colored yellow, it can be used as it is as a road display. Therefore, the snow-melting block is placed in the center of the road. Arrangement is also possible substantially. Of course, the color of the upper surface of the block is not limited to yellow, but it can be any color that is needed, especially if it is the same color as the road surface (like black on an asphalt road), it will not be noticeable on the road surface So
There is an advantage that it is not confused with the road display when driving at night.

INDUSTRIAL APPLICABILITY The present invention is a snow-melting block for a snow-melting road in which the water pipes and the water-spraying nozzles are integrated with concrete as described above. It was possible to display roads at the same time as laying, and to make blocks inconspicuous.
