Description

TECHNICAL FIELD The present invention relates to a tubular snowy road.

Conventional technology In heavy snowfall areas, snow is removed from roads by snow removal work, and the scraped snow is discharged by a snow-driving path provided beside the road. As a conventional snow drift path, a concrete snow drift groove having a U-shaped cross section is generally used, and the snow thrown into the snow drift groove is sequentially swept to the downstream side by the flowing water. It is like this.

Problems to be Solved by the Invention By the way, it is customary to install utility poles for electric power, telephones, and other signal lines alongside roads where snowy roads are installed. However, in the past, there is a problem that this electric pole tends to hinder snow removal work.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to solve the above problems and provide a tubular snowy road that can eliminate electric poles that hinder snow removal work.

Means for Solving the Problems In order to achieve the above object, the present invention provides a pair of wall layer portions, which are in contact with the inner surface of the pipe body and have a thickness in the pipe radial direction, on both sides inside the pipe body in the pipe axial direction. Provided over the wall layer, a snow drifting portion is provided in the center of the pipe body sandwiched between the wall layer portions, a hole in the pipe axis direction is formed inside the wall layer portion, and a cable is passed through the hole portion, A step portion is formed on an upper surface of the wall layer portion, and a snow melting pipe having a water spouting hole capable of ejecting water toward the snow drift portion is arranged on the step portion.

Action With this configuration, the cable is passed through the hole formed inside the wall layer provided on the side of the snow drifting part, so there is no need to install a utility pole on the ground, and snow removal is possible. The inconvenience that work is hindered is eliminated.
Moreover, since the passage for snow flow and the laying passage for the cable are shared by one pipe, the installation space is smaller and the installation work is easier than the case where these are installed separately. Becomes Further, since a pair of wall layer portions that are in contact with the inner surface of the pipe body and have a thickness in the pipe radial direction are provided on both sides inside the pipe body in the pipe axial direction, the pipe body is reinforced by these wall layer portions. Is possible, which is particularly advantageous when a snowy road is buried in the ground such as a road that is heavily loaded. In addition, because the snow melting pipe with the water spray holes that can eject water toward the snow drifting part is arranged on the step formed on the upper surface of the wall layer, the snow melting pipe can be installed easily and reliably using the step. In addition, even if a large snow mass is thrown into the snow drift part, it can be efficiently swept away by melting it and making it smaller.

Example 1 In FIG. 1, reference numeral 1 denotes a tubular body constituting a snowy road, which is made of a cast iron pipe, a resin pipe or the like, and is buried in the soil. On both inner sides of the tube body 1, wall layer portions 2 and 3 extending in the tube axis direction are provided, respectively. These wall layer portions 2 and 3 are made of a material such as concrete, and when they are made of concrete, the reinforcing bars 4 are arranged inside. As shown in the figure, the wall layer portions 2 and 3 are formed in contact with the inside of the tubular body 1 and have a constant thickness along the horizontal direction, that is, the radial direction of the pipe. Also, these wall layers
A snow drift part 5 is formed in the central part of the pipe body 1 sandwiched between the two and three, and a natural sewage 6 is flown into the snow drift part 5.

Each of the wall layer portions 2 and 3 is formed with a plurality of hole portions 7 extending in the pipe axial direction and vertically extending through the wall layer portions 2 and 3, respectively.
The holes 7 can be formed by using a suitable core when pouring concrete for forming the wall layers 2 and 3, for example. Alternatively, the pipes can be formed by arranging pipes inside the tubular body 1 and then pouring concrete for the wall layers 2 and 3 and burying the pipes in the wall layers 2 and 3. A cable 8 is passed through each hole 7.

A step 9 is formed on the upper surface of the wall layers 2 and 3, and the step 9 is formed.
A snow-melting pipe 10 is arranged in the wall of the wall and fixed to the wall layers 2 and 3 by an anchor 11. In this snow melting pipe 10, water 12 is passed inside, and a plurality of water spray holes 13 penetrating the pipe wall are formed in the pipe axial direction so that the water 12 can be jetted toward the snow drifting part 5. There is.

Such a tubular snowy road has a configuration in which a snow throwing pipe unit having a snow throwing port and a pipe unit having no snow throwing port are appropriately connected in the lateral direction. FIG. 2 shows an example of a snow throwing pipe unit. This snow throwing pipe unit is at the top of the pipe 1,
The structure has a snow throwing port 15 that opens to the ground surface 14.

In such a structure, the snow 16 thrown from the snow throwing port 15 into the snow drift part 5 in the pipe is sequentially swept to the downstream side by the natural flowing sewage 6 flowing in the snow drift part 5. In this case, even if a large lump of snow is thrown, the lump of snow is melted by the water 12 from the snow melting pipe 10, becomes smaller, and is efficiently washed away.

Moreover, since the cables 8 are passed through the holes 7 in the wall layers 2 and 3, it is not necessary to install utility poles for these cables 8 on the ground, and the utility poles interfere with snow removal work. Can be prevented. Moreover, since the snow drift portion 5 and the wall layer portions 2 and 3 for passing the cable 8 are both provided inside the pipe body 1, the installation space can be reduced as compared with the case where these are separately provided. In addition, the installation work becomes easy.

As described above, according to the present invention, the wall layer is provided inside the pipe body in addition to the snow drift part, and the cable is passed through the hole in the wall layer. It is not necessary to install a utility pole for the snow on the ground, and snow removal work can be performed easily. Moreover, since the passage for snow drifts and the laying route for the cables are shared by one pipe, the installation space can be made smaller compared to the case where they are arranged separately, and the installation work is easy. It can be anything. Further, since a pair of wall layer portions that are in contact with the inner surface of the pipe body and have a thickness in the pipe radial direction are provided on both sides inside the pipe body in the pipe axial direction, the pipe body is reinforced by these wall layer portions. This is particularly advantageous when a snowy road is buried in the ground such as a road that is heavily loaded. In addition, since the snow melting pipe having the water spray holes capable of ejecting water toward the snow-flowing part is arranged on the step formed on the upper surface of the wall layer, the snow melting pipe can be easily and surely installed by using the step. Moreover, even if a large snow mass is thrown into the snow drift part, it can be efficiently swept away by melting it and making it smaller.
