WATER LEVEL ADJUSTMENT DEVICE FOR PADDY FIELD WITH RICE FIELD DAM FUNCTION AND METHOD FOR DAMMING RICE FIELD
PROBLEM TO BE SOLVED: To provide a paddy water level adjustment device with a paddy dam mechanism that can impart a dam function in a rice field by storing increased paddy water from a rice field and releasing the water little by little to prevent flooding on a downstream side, using a water level adjuster installed on a ridge, and to provide a method for damming the paddy field.SOLUTION: In a water level adjuster 1, a rear wall 2C and a pair of side walls 2B are erected on a bottom plate so as to be formed in a substantially rectangular shape in a plan view, and a pressure receiving plate 3 and a water level adjusting plate 4 are inserted. A dam plate 6 of a rice paddy dam mechanism 5 made of aluminum has a taller height than the water level adjusting plate 4, and a water discharge hole of a smaller diameter than a drain hole of the rear wall 2C is provided in the lower side. The dam plate 6 and support plates 7 of both ends are formed so as to be a substantially H shape in a plan view. The paddy dam mechanism 5 is inserted between the rear wall 2C of the water level adjuster 1 and the water level adjusting plate 4, and the water level adjusting plate 4 is stored in the storage tank 8 and is released little by little from the water discharge hole.SELECTED DRAWING: Figure 1
【課題】畦に設置する水位調整器を利用し、増水した田んぼからの水田水を貯留しつつ少しずつ放出して下流側の水害を防止し、田んぼにダム機能を持たせることができるようにした田んぼダム機構を有する水田用水位調整装置及び水田のダム化法を提供する。【解決手段】水位調整器１は底板に後壁２Ｃ及び一対の側壁２Ｂを立設して平面視で略冂字状に形成し、受圧板３と水位調整板４が挿設してある。アルミニュウム製の田んぼダム機構５のダム板６は水位調整板４より背高で、後壁２Ｃの排水穴より小径の放水穴が下側に設けてある。ダム板６と両端の支持板７とから平面視で略Ｈ字状に形成してある。田んぼダム機構５は水位調整器１の後壁２Ｃと水位調整板４との間に挿設し、水位調整板４を越流した水田水は貯留槽８に貯留しつつ放水穴から少しずつ放出する。【選択図】図１
