摘要： PROBLEM TO BE SOLVED: To provide a water level controller which allows irrigation water to be quickly supplied to or discharged from a paddy field, and is easily cleaned to remove mud, sand or the like which builds up in the device. SOLUTION: This water level controller is for an irrigation water supply/ discharge system for a paddy field, wherein water flowing into a lower chamber 11b of a water supply/discharge measure body 11 via a water supply section 15 moves into a controlling section 11g in an upper chamber 11a via an opening provided in a partition plate 12 in the water supply/discharge measure body 11, and then into a communication tube 11f leading to the paddy field via a water supply hole 18a in a third partition wall 18. Water is then supplied from the communication tube 11f to each farming section in the paddy field via a water supply/discharge tube 19. Water in the farming section flows downward, via a water level controlling tube 22, into a water discharge section in the lower chamber 11b in the water supply/discharge measure body 11, when its level exceeds the upper side of the water level controlling tube 22, being discharged out of the water supply/discharge measure body 11 via a water discharge tube section 16.

摘要： PURPOSE:To easily connect pipes by self-seal action using a simple collar method by joining a rubber cylinder and a perforated reinforcing cylinder to each other with a clearance held between the rubber cylinder and the reinforcing cylinder. CONSTITUTION:Both end parts 11, 11 of a rubber cylinder 1 are made thicker, the intermediate part is made thinner, and grooves 13 for loading the end parts of a reinforcing cylinder are provided respectively to the thicker sections of both the end parts. The perforated reinforcing cylinder 2 whose both ends are loaded into the grooves 13 is provided, and as the reinforcing cylinder 2, a material having sufficiently large rigidity compared to rubber material, for example, a cylinder body made of steel, vinyl chloride resin, or FRP is used. Besides, a clearance 3 is provided between the rubber cylinder 1 and the reinforcing cylinder. In order to connect strong pipes capable of withstanding the pressure applied in cases where the thrust piping method is employed, for example, FRT pipes by such a pipe fitting A, the pipe fitting A is fitted so that it is laid over between grooves 41, 41. formed on the FRP pipes 4. Due to the pressure of underground water entered into the clearance 3 through holes 21... of the reinforcing cylinder 2, self-seal action can be realized.
