Description

[Detailed description of the invention] << Industrial application field >> This invention relates to a branch channel in a water channel such as a drainage channel or a snow channel, more specifically, a U-shaped channel used for a snow channel in a road. Regarding branch grooves.

<< Conventional Technology >> A water channel, particularly a drainage channel, is generally provided with a U-shaped groove or an L-shaped groove on a road side or under the road in order to allow rainwater or snow to flow. In particular, a drainage furnace in a snowy country or the like uses a large U-shaped ditch (snow ditch) for snowfall in order to eliminate a large amount of snow in winter.

When a large amount of snowmelt in the early spring flows into such a drainage channel or snow drift, it is necessary to share the discharge destination of the snowfall or running water. For this reason, the drainage channel and the snow channel have been branched, and a branch channel has been provided in order to select the discharge destination of the snow melt. In this branch groove, a narrow engagement groove is formed vertically in the two waterway portions at the end of the branch point, and dropped into the engagement narrow groove of one of the waterways, and a plate-shaped stone (waterproof stone (20)) And the water flow through one of the channels was stopped (FIG. 5).

In addition, a branch groove is used in a waterway for selecting a headrace, such as a waterway to a rice field. However, such a branch groove has the same configuration as that described above. In this case, one of the channels is stopped and the other channel is allowed to flow by changing the channel from an existing channel to a new channel.

In addition, as in the case of "a blocking device in a snowfall ditch" described in Japanese Utility Model Application Laid-Open No. 63-104480, a turning shaft is provided at a branch point portion, and the turning portion is manually turned by a grip portion on an upper portion of a water control plate. Branch grooves are also known.

《Problem to be solved by the present invention》 In the case of a conventional branch groove (19), a stone block (20) for stopping water is required according to the size of the channel, and it is necessary to change the channel. In this case, it is necessary to pull up the water stopping stone once from the groove in which it is fitted, and to fit it into the groove in another channel. However, in general, the waterway fills the groove where sand, soil, dust, etc.
There is a problem that the water stopping stone slab (20) does not move easily and cannot be lifted. In particular, in snowy regions such as snowy countries, a large amount of snow-melting water in the form of sherbet flows into drains and snow channels during welding, and the water pressure is high due to the melting of snow in the branch channels of the drain channels, and it is very cold.
There is a problem that it is very difficult to change the water path of the branch groove by lifting the water stoppage stone (20) from the engagement narrow groove, or to rotate the water control plate manually by freezing. Was.

Furthermore, if the branch drainage is planned systematically, such as a drainage channel in a development site, or if the drainage destination of the drainage channel is planned to be changed, only a branch ditches should be initially provided and appropriate after the development, etc. It is common to establish an extension waterway at the appropriate time. However, it is necessary to provide a branch channel as in the past, and to stop the flow of water through the non-installed planned drainage channel with a water stoppage stone (20).
It was not preferable because of the water pressure and the like. Therefore, in such a case, there is a problem that the branch point must be dug up and a new branch groove must be provided in place of the ordinary U-shaped groove at that portion.

An object of the present invention is to obtain a branch groove that can change the flow direction of a water channel very easily even in a branch groove of a water channel, even if it resists the pressure of flowing water.

It is another object of the present invention to obtain a branch groove having a water control plate that is in contact with the wall surface of the branch groove in a water-tight manner and that reliably branches running water, flowing snow and the like.

A further object of the present invention is to provide a waterway in which the branch waterway can be easily constructed by providing the branch groove in the waterway from the beginning.

<< Means for Solving the Problems >> The present invention provides a rotating shaft erected at a branch point of a branch groove, a water control plate having a tip with one end attached to the rotating shaft facing upstream. A rotating device that is connected to the rotating shaft and rotates the water control plate, and an elastic plate-like body that covers the side of the rotating shaft from both sides of the water control plate so as to become narrower toward the upstream side. A branch groove is provided.

<< Operation >> A branch groove is provided in a waterway and is erected at a branch point. The rotating shaft is covered from both sides by an elastic plate-like body, and the flowing shaft is reduced, and the rotating shaft is protected from snow, a stone in flowing water, and a plate.
