Abstract
The present invention relates to inflatable bladder actuated water control gates for control of open channels such as rivers and canals and for control of dam spillways without the need for intermediate piers. The air bladder and hinge flap wedge clamping system includes hinged engagement of the upstream edge of the clamps to the foundation so as to prevent the application of bending and shear loads to the anchor bolts. The resulting configuration facilitates the use of high strength alloy steel anchor bolts in a corrosion protected environment and also prevents tensile loading of the concrete foundation and associated cracking of the concrete foundation.
Claims24
A water control gate clamping system comprising:
- a foundation,
- a water control gate clamp casting,
- a clamp pivot embed,
- an anchor bolt, having a sleeved and unsleeved portion, and nut assembly,
- an anchor bolt sleeve,
- a water occlusion system
- and where in said water occlusion system comprises:
- a clamp casting anchor bolt hole cover;
- a compressible rubber seal with an upper end and a lower end;
- an anchor bolt upper spacer;
- and
- a water and oxygen displacing substance
- and wherein said compressible rubber seal is positioned on top of said horizontal portion of said anchor bolt upper spacer and surrounds a portion said anchor bolt sleeve,
- and wherein said compressible rubber seal is shaped so that the upper end is slidably positioned into a clamp casting bolt hole.
