Sluice gate
A tank arrangement, duplicate cross-sectional restrictions, side roller block, openable reaction roller, openable bottom seal, reaction axle, openable side seal, gate slot inserting steps and a stress reduction cross-sectional restriction are presented to implement an emerging movement type opening/closing gate equipped with advantageous torsion structure. The arrangement enables a gate body to be operated in submerged-body state, the cross-sectional restrictions can correspond to both high tide pressure and tide flow pressure which are different in qualities, the side roller block, the openable reaction roller and the openable bottom seal resolve spatial interference problems in gate operation, compact reaction axles which endure big load enables cross-sectional restriction points at a narrow gap in a storage space, the openable side seal and the gate slot inserting steps prevent side seal rubber from damage and the stress reduction cross-sectional restriction can cut high tide pressure torsion moment by more than 50%.
