Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow drift groove that discards snow accumulated on a road or the like.

[0002]

[Prior Art]

 As a conventional snow drift groove, the one described in Japanese Patent Application Laid-Open No. 64-29534 is known. This snow flow ditch is equipped with a secondary canal that connects to the main canal via a perforated plate, and when the main canal is closed by the injected snow mass, drainage flows such as snowmelt water and miscellaneous drainage flowing through the main canal are discharged. It is designed to be released to the sub-drain to prevent the snowmelt water and miscellaneous drainage from overflowing the road.

[0003]

[Problems to be solved by the device]

 However, according to the conventional flowing water groove, the perforated plate is likely to be clogged with dust, foreign matter, etc. contained in the drainage flow, and there is a high possibility that the secondary water channel will not function.

Further, the above-mentioned snow drift has the action of melting the snowflakes by the drainage flow flowing through the sub-channel, but since the drainage flow contacts the snowflakes through the perforated plate, in other words, the drainage flow and the snowfall The snow melting efficiency was low due to indirect contact with the snow, and it took a considerable amount of time for the snow to melt.

The present invention has been made in view of the conventional circumstances as described above, and an object thereof is to prevent clogging between a main waterway and a subwaterway, and to make a snow mass in a shorter time. It is to provide a snowdrift that can melt the snow.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the snow drift groove of the present invention is provided with a large number of protrusions vertically arranged in multiple stages at appropriate intervals on the vertical inner surface of the main water channel facing the main water channel formed in the snow drift pipe body. At the same time, it is characterized in that the protrusion is provided over the entire length of the main water channel.

[0007]

[Action]

 According to the above means, a sub-channel that opens parallel to the main channel is formed between adjacent ridges, and if the main channel is closed by the injected snow mass, the snowmelt water or miscellaneous drainage that flows through the main channel will be formed. The drainage flow of water etc. is allowed to escape into the secondary canal to prevent snowmelt water and miscellaneous drainage from overflowing on the canal.

Further, since the sub-waterway is opened in parallel with the main waterway, and the main waterway and the subwaterway communicate with each other, there is almost no possibility that the communication portion is clogged. At the same time, the drainage flow in the secondary canal directly contacts the snow mass, which greatly improves the snow melting efficiency.

【Example】

 Hereinafter, embodiments will be described with reference to the drawings. In the figure, A indicates an embodiment of the snow drift groove of the present invention.

The snow drift groove A is formed by forming a large number of ridges 3 in a main water passage 2 formed in a snow drift pipe body 1, and is embedded in a road shoulder or the like in a state where a large number of them are connected as shown in FIG. To be done.

The snow drift pipe body 1 is a pipe body having a rectangular cross section in which the upper and lower left and right wall portions 1a, 1b, 1c and 1c are formed using concrete and the communication ports 1d and 1d are opened on the front and rear surfaces. The hollow interior formed and surrounded by the walls 1a to 1c is defined as a main water channel 2 communicating with both the communication ports 1d and 1d.

On the inner surfaces of the left and right wall portions 1c, 1c, that is, the vertical inner surfaces facing each other in the length direction of the main water channel 2, a plurality of ridges 3 and sub water channels 4 extending in the length direction of the main water channel 2 are provided. The walls 1c, 1c are formed in a multi-stage shape with some margin left at the upper and lower ends in the height direction.

A large number of protrusions 3, 3, ... Are provided so as to be parallel to each other at equal intervals and over the entire length in the longitudinal direction of the facing vertical inner surface.

The sub channels 4, 4, ... Are formed along the entire length of the main channel 2 so as to open in parallel with the main channel 2 between the adjacent ridges 3, 3. .

As shown in the figure, the upper and lower ends of the facing vertical inner surface are chamfered portions 5 so that the snow block that closes the main water channel 2 is directed toward the center of the main water channel 2 as much as possible, and the sub water channel 4 is This prevents the possibility of snowfall at the four corners of the main waterway 2 at the same time.

FIG. 2 shows a state in which a large number of the above-mentioned snow drift grooves A are connected and installed on a road shoulder, and B in the figure is a snow throwing stub standing upright in the snow drift grooves A ′.

In the sill B, a middle sill 11 and an upper sill 12 for introducing snow are erected in a snow spill groove A ′ for the snow throwing part installed between the snow spill grooves A and A, and It is constructed by arranging a mud tank 13 under the groove A '.

The snow drift groove A ′ is formed by opening an upper opening 10a and a lower opening 10a at a portion of the snow drift groove A in the lengthwise direction of the snow drift conduit 1, and opening the lower opening 10a in the mud trap. It is installed directly above 13. Further, on the upper wall portion 1a, an intermediate container 11 and an upper container 12 are placed in communication with the upper opening 10a to form a part of the container portion B. Reference numeral 14 is a perforated plate attached to the lower opening 10a.

In the running water groove A of the present embodiment having the above-mentioned configuration, the communication port 1d is connected to the communication ports 1d of the adjacent running snow grooves A, and a large number of them are continuously installed. Part B is installed and installed on the road shoulder. The snow mass thrown in from the basin B is melted by a drainage flow of snowmelt water, miscellaneous drainage, etc., and becomes snowmelt water, which flows down in the main waterway 2 and is drained.

Further, when the main water channel 2 is closed by the injected snowflakes, drainage flows such as snow melting water and miscellaneous wastewater flowing through the main water channel 2 are released into the sub water channel 4, and the snow melting water / miscellaneous drainage is discharged on the road. Prevent it from overflowing.

Further, the sub-water passage 4 is opened in parallel with the main water passage 2, and the main water passage 2 and the sub-water passage 4 communicate with each other, so that the communication portion is hardly clogged. At the same time, the drainage flow that flows through the sub-drain 4 directly contacts the snow mass, which greatly improves the snow melting efficiency.

In the present embodiment, the plurality of ridges 3 are provided only on the facing vertical inner surface side of the main water channel 2, but, for example, the inner surface of the lower wall portion 1b of the snow drift tube body 1 (of the main water channel 2) It may be provided on the bottom surface) or on the inner surface of the upper wall portion 1a (upper surface of the main water channel 2), or may be provided on the entire inner surface of the snow drift tube body 1.

[0023]

[Effect of the device]

 Since the snow drift groove of the present invention is configured as described above, even if the main canal is closed by a snow mass, drainage is performed through the sub canal and the snow mass is efficiently melted by the drainage flow. , It is possible to promptly eliminate the closure of the main canal due to snowflakes. In addition, since the above-mentioned sub-channel is opened parallel to the main channel, it does not cause clogging unlike the perforated plate.

Therefore, there is less risk that the drainage path will be clogged as compared with the conventional case, and moreover, there is an effect that the snow mass can be melted in a short time and snow melting and drainage can be performed more efficiently.
