のを防止できる。Next, the operation of the sluice gate of the present invention will be described with reference to FIGS. In the sluice door 10 of the present invention, when the water channel 22 is opened, the wire rope 15 suspending the door body 11 is released to unwind and the hydraulic pressure for supporting the door body 11 from below. The jack 16 is contracted and lowered by the weight of the door body 11 itself.
As a result, the door body 11 gradually descends along the door groove 12 until its upper end surface is housed in the door body housing groove 13, while
The door groove protection frame 14 is integrated with the door body 11 and gradually descends through the door groove 12. Therefore, the door groove 12 is always fitted to either side of the door body 11 or the door groove protection frame 14. Then, the water channel 22 is opened, and the water flows over the door 11.
Therefore, foreign matter such as gravel can be prevented from entering the door groove 12 when the water channel is opened.

る。On the contrary, in order to close the water channel 22, the wire rope 15 suspending the door body 11 is wound up by a motor, and the hydraulic jack 16 supporting the door body 11 from below is extended. The door groove protection frame 14 and the door body 11 are integrally lifted. Therefore, when the water channel is closed, the door groove 12 is always fitted with both side surfaces of the door body 11 or the door groove protection frame 14, and foreign matter such as gravel can be prevented from entering the door groove 12. Further, at this time, when water is pressure-fed from the water supply device through the water supply pipe 11c and ejected from the injection nozzle 11b toward the foreign matter 21 such as accumulated gravel and mud, the water pressure and the door of the wedge shape 11a. Due to the rising pressure of the upper end surface of the body, the foreign matters 21 such as gravel and mud accumulated on the upper end of the door body 11 are pushed away to the upstream side and the downstream side and eliminated.
Therefore, the door body 11 includes the door body storage groove 13 to the door groove 12.
You can smoothly climb along and close the waterway.

路閉鎖が可能になる。In the sluice gate of the present invention, the door groove is provided on both sides of the water channel, and the door body storage groove is provided in the bottom of the water channel so as to be continuous with the door groove, and the door body for blocking the water channel is provided. Since it is arranged so that it can move up and down along the door groove and is formed so that it can be housed by being fitted in the door body housing groove, and a drive device for raising the door body is provided, the door body is opened when the water channel is opened. You can store it in the body storage groove and pass running water over the door body,
On the other hand, if the door body housed in the door body housing groove is raised along the door groove, the water channel can be closed. Therefore, even if foreign matter such as gravel or mud accumulates on the door body when the waterway is opened, the foreign matter can be pushed back and forth at the upper end of the door body by moving the door body up with the drive device, and smoothing is possible. It is possible to close various waterways.

When the door gradually descends along the door groove, the door groove protection frame fits into the door groove and descends. On the contrary, when the water channel is closed, the door groove fitted into the door groove is closed. When the protective frame rises, the door body rises while fitting into the door groove. Therefore, since either the door body or the door groove protection frame is always fitted in the door groove, gravel,
