Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a snow-melting block installed on a road in order to melt snow on the road surface by sprinkling water.

(Prior art) A snow-melting road that melts snow on the road surface with water sprinkling generally has a ditch at the center of the road, a water pipe is placed at the bottom of the groove, and water sprinkling nozzles connected to the water 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. But,
Since the above construction will worsen the traffic conditions on the road, in order to shorten the construction period, prepare a snow removal block in which the water pipe and sprinkling nozzle buried in the groove are integrated with concrete etc. in advance and dug it on the road. It is known to embed the blocks in the perforated grooves and connect the blocks to form a snow-melting road (Japanese Utility Model Publication No. 55-13459 and Japanese Patent Publication No. 60-25831).

(Problems to be solved by the invention) By the way, a water pipe used for a snow-melting road is so far away from the water source that a sufficient watering pressure can be obtained even at a place far from the water source where water is sprinkled on the way and the amount of water decreases. The diameter of the water pipe is reduced.

The water pipe used in the above-mentioned snow block has a uniform diameter. For this reason, for connection of snow-melting blocks using water pipes of the same diameter, for example, as shown in FIG. 3 of Japanese Patent Laid-Open No. 60-25831, the water pipes are butted and the butted portions are joined by a connecting member ( It is good to cover the inner surface with a rubber-covered split cylinder, but especially when connecting snow-blending books with different diameters, centering to locate the center of the water pipe is complicated, and a connecting sleeve etc. should be used. Since the work is done on-site and the work of connection is performed, the work period for different-diameter connection is longer than that for same-diameter connection. At branch points such as road intersections, connections with different diameters will always occur, so prolonging the construction period will significantly deteriorate traffic conditions. In addition, since there is a large amount of traffic at the branch point, it is necessary to make it robust so as to prevent damage due to the weight of the vehicle.

Therefore, the present invention is to provide a snow-removing block that can be used particularly in a part requiring a different diameter connection in a snow-removing line,
The purpose is to significantly shorten the construction period and to solidify branch points such as intersections.

(Means for Solving the Problem) A snow-melting block according to the present invention is a snow-melting block in which a water pipe and a water spray nozzle body connected to the water pipe at appropriate intervals are integrated in a rod shape with concrete. It is characterized in that water pipes having different diameters are provided at the ends of the block body in a projecting manner. Further, in the snow-removing block, the block body is integrally formed in a cross shape or a T shape and the block is formed. It is characterized in that water pipes having different diameters are provided at the ends of the body so as to project.

(Operation) When connecting the snow-melting blocks to form the snow-melting line of the snow-melting road, if the snow-melting blocks of the present invention are placed at the places where the diameter of the water passage should be changed, the snow-melting blocks will be connected. Are all pipes of the same diameter. In addition, the branch point is always formed of concrete with reinforcing bars.

(Example) Next, an example of the present invention will be described.

<First Embodiment> The first embodiment is a rod-shaped snow-dissipating block as shown in FIGS. 1 and 2, and basically has a water pipe 1 and a water pipe 1 similar to the conventional one. A watering nozzle 2 connected at appropriate intervals,
It is composed of a concrete body 3 that integrates these into a rod shape and a reinforcing bar 4 for reinforcing the concrete body 3, but in particular, the water pipe 1 is not a single pipe, but two pipes of different sizes Of the water pipes 11 and 12 and a sleeve 13 formed by connecting the water pipes 11 and 12 having different diameters. Each end of the water pipes 11 and 12 is projected to the outside of the concrete body 3 to form a connecting portion 14. , 15
Is formed.

The structure of the water spray nozzle 2 and the connecting means for connecting the water pipes 11 and 12 are arbitrary.

<Second Embodiment> As shown in FIGS. 4 and 5, the second embodiment is composed of a water pipe 10, a sprinkler nozzle 20, a concrete body 30 and a reinforcing bar 40 as in the first embodiment, but in particular, Large diameter water pipe 10
101 is connected to a small diameter water pipe 102 by welding,
Along with this, the concrete body 30 is also formed in a cross shape, and the end portions of the water pipes 101 and 102 are the concrete body 30.
The connecting portions 104 and 105 are made to project further.

The water pipes 101 and 102 may be branched in a T shape by using a sleeve 130 instead of being crossed as in the third embodiment shown in FIG. 6, etc. For connecting the water pipes with different diameters, any means may be used. You can

<Example of Use of Example> An example of use of the snow-blocking block of the present invention will be described below.

In order to help understanding, the diameter of the water pipe will be described as two types, large and small. As shown in FIG. 3, the snow-melting blocks are connected by using a connecting tool 5 that covers the joints of the water pipes 1 that are butted against each other from the outside. The cylindrical body is clamped with, and is covered and connected so as to prevent water leakage. Further, as the snow-melting block, the snow-melting block A of the first embodiment of the present invention,
The snow removing block B, the conventional water passage pipe having a large diameter, and the conventional water passage pipe having a small diameter are used, respectively, in the second embodiment.

Then, as shown in FIG. 7, for a snow-melting road near the water source, snow-melting blocks B (large diameter) are sequentially connected, and at the intersections, snow-melting blocks A are used, and the main line is re-used. The snow-melting block B is connected, and a small-diameter snow-melting block D is connected to the branched road. Furthermore, if it is necessary to reduce the diameter of the water pipe even if it is farther from the water source even on the main road, the snow removing block B of the present invention is used, and the small diameter snow removing block D is connected to this.

It should be noted that the number of block diameters is not limited to two, but several types are prepared. Correspondingly, the combination of different diameter water pipes of the snow-removing block of the present invention is appropriately determined as necessary, and the branch point It is natural that the T-shaped block is also used as the block used for.

(Effect of the invention) As described above, the present invention is applied to a place where the diameter of the water pipe is changed in a snow-melting block where the diameter of the connecting portion at each end of the water pipe is different, or where the diameter of the water pipe must be changed, such as at an intersection. When it is used, the connection of the snow-melting blocks will always be the connection of the water pipes of the same diameter in the construction of the snow-melting road, the construction of the connecting portion will be easy, and the construction period will be shortened.
