PURPOSE: environmental protection construction method, which is provided to discharge clear water, has huge specific gravity, even if water gate is closed. ;CONSTITUTION: lower concrete structure and H profile steel and unequal angle are constituted on bracket. The outer surface water gate of axis (10) establishes concrete structure. Operation (9) is fixed on the axis water gate of bracket. Piston rod and cylinder body (2) are formed in tip operation support bracket. Pass through hinge in the cylinder axis connection (6) of cylinder. The axis of cylinder is combined with the water gate of a connecting plate (8). The axis and water gate of the plate water gate and hinge. ;The 2010 of copyright KIPO submissions
