WATER LEVEL REGULATING DEVICE FOR RICE PADDY, DAMN MECHANISM AND METHOD FOR DAMNING RICE PADDY
PROBLEM TO BE SOLVED: To provide a water level regulating device for a rice paddy, etc. which combines a water level regulator installed on a ridge with a dam mechanism, dams the rice paddy, and prevents flood damage by suppressing the amount of water discharged.SOLUTION: This water level regulating device comprises a water level regulator for regulating the water level of a rice paddy by installing a height variable water level regulating plate in a basin body having a rear wall with a drainage hole and a pair of side walls erected in a substantially U shape on the bottom plate in a plan view. A vertical groove is provided in the pair of side walls between the rear wall and the water level regulating plate and a dam plate formed at a height higher than the water level regulating plate and provided with a water discharge hole of a smaller diameter than the drainage hole on the lower side of the plate body is provided. A dam mechanism configured to have a substantially U shape in a plan view is provided with a pair of support portions at both ends of the damn plate in the width direction, and by inserting the pair of supporting portions in the vertical groove in a direction in which the pair of supporting portions are positioned in the lateral direction or the vertical direction of the dam plate, paddy water overflowing the water level regulating plate is discharged little by little from the water discharge hole to the drainage hole side while being stored in the water level regulator.SELECTED DRAWING: Figure 1
【課題】畦に設置する水位調整器にダム機構を組み合わせ、田んぼをダム化し、また放水量を抑制して水害を防止することができる水田用水位調整装置等を提供する。【解決手段】排水穴を有する後壁および一対の側壁を底板に平面視で略匚字状に立設してなる桝本体内に高さの可変な水位調整板を設置して水田の水位調整を行う水位調整器において、前記後壁と前記水位調整板との間に位置して前記一対の側壁に縦溝を設け、前記水位調整板より背高に形成されて板本体の下部側に前記排水穴より小径の放水穴を設けたダム板と、該ダム板の幅方向両端に設けられた一対の支持部とから、平面視で略コ字状に構成してあるダム機構を、前記一対の支持部が前記ダム板の左右方向又は上下方向に位置する向きで、前記縦溝に挿嵌することにより、前記水位調整板を越流する水田水を前記水位調整器内に貯留しつつ前記放水穴から前記排水穴側に少しずつ排出する水田用水位調整装置。【選択図】図１
