Abstract
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.
Claims11
A water gate panel apparatus comprising:
- a concrete water control gate panel body element;
- a slide friction reduced, actuator-side water control gate panel surface element responsive to said concrete water control gate panel body element;
- a horizontal axis rotation hinge-to-water gate panel attachment element fixedly positioned at an overflow orthogonal installed water gate panel bottom edge and to which said concrete water control gate panel body element is responsive
- a polymeric plate element dimensioned to contact a planar abutment seal face throughout a possible water gate position vertical edge sweep;
- and
- a plate-to-foundation surface attachment element to which said polymeric plate element is responsive,
- wherein said plate-to-foundation surface attachment element comprises a plurality of fastener holes separated by an average, nearest fastener hole separation distance, and
- wherein said average, nearest fastener hole separation distance divided by a polymeric plate element thickness is less than approximately twelve.
