The invention relates to improved water control gates and related inflatable actuators, and associated sealing, manufacture and operation apparatus and methods. Advancements in technologies related to air fitting design, inflated bladder stress relief, inflatable bladder strength enhancement, water gate related slide friction mitigation, abutment and other impounded water seals, gate panel fabrication, traffic accommodating water impoundment structures, and water gate panel system operation efficiency, as well as nappe aeration, hinges, and bladder manufacture technology are disclosed herein.

Water control apparatus

Several gate panels are pivotably mounted on top of a dam spillway which are raised against the force of water by inflatable bladders. The bladders are integrally vulcanized envelopes. A unique method of inflatable bladder reinforcement is disclosed. Improvements in connecting the gate panels to the air bladder, to the restraining straps, to each other, and to the dam spillway are disclosed. Improvements in gate panel construction are disclosed.
