Description

  The present invention relates to a controlled water tank used in, for example, a paddy drainage or submerged irrigation facility.

Conventionally, in order to manage wetlands and dry rice fields, underground water under the paddy field is absorbed into the water collection pipe when the underdrain drainage valve is opened, and drained into the drainage channel through the drainage pipe and joint pipe. On the other hand, when the underdrain valve is closed, the drainage from the water collecting pipe is blocked, so that the underground water stops under the paddy field and the paddy field is converted into a wetland.
As such, utility model registration No. 3089402 filed as an improvement of the present applicant is known.
However, in the conventional culvert drainage valve, since the upper end of the standing pipe and the upper end of the operation tub project to the ground at the shore, the upper end of the culvert drainage valve obstructs work such as mowing on the shore. At the same time, there was a risk that the underdrain drainage valve would be damaged by agricultural machinery.
Therefore, a culvert drainage valve that is not disturbed by work, can be prevented from being damaged by agricultural machinery, and can be prevented from being deteriorated by ultraviolet rays or the like is known as Utility Model Registration No. 3037421.

In the utility model registration No. 3037421, as shown in FIG. 3, since the operation handle 64 is in the protective box 51 and the upper surface opening of the protective box 51 is closed by the lid 54, only the lid 54 is attached. The cover 54 can be exposed to the ground and the other part can be buried in the ground. Further, the lid 54 has a fitting portion 55 on its lower surface fitted in the protective box 51, and the periphery of the fitting portion 55. Since the step portion 56 is configured to be placed on the upper end surface of the protection box 51, the entire protection box 51 can be buried in the ground, and the substantially flat lid 54 can be disposed on the same surface as the ground surface 22a of the shoreline 22. It is a valve for culvert drainage.
However, since the height from the joint pipe 42 communicating with the water collecting pipe 26 to the ground surface 22a of the shore 22 is not constant, the above-described known technique allows the upper end of the underdrain drainage valve 41, that is, the lid 54 to be connected to the shore 22 In order to be positioned on the ground surface 22a, it was necessary to cut the standing tube 45 and the operating rod 62 to appropriate lengths.
