2. TIDE GATES SHALL BE A MEDIUM DUTY AUTOMATIC DRAINAGE, THE CONTRACTOR SHALL SUBMIT TO THE PROJECT ENGINEER TECHNICAL

SPECIFICATIONS OF TIDE GATE 6 WEEKS PRIOR TO INSTALLATION.

3. THE FOLLOWING REQUIREMENTS ARE MINIMUM AND MUST BE MET BY THE TIDE GATE MANUFACTURER UNLESS OTHERWISE APPROVED IN WRITING BY THE

ENGINEER.

THE FRAME, COVER, AND HINGE LINK SHALL BE ALUMINUM ALLOY 6061 - T6, ALL SURFACES SHALL HAVE A MILL FINISH.

THE HINGE MECHANISM (BOLTS, WASHERS AND NUTS) SHALL BE TYPE 304 STAINLESS STEEL MEETING THE REQUIREMENTS OF ASTM F 593.

THE "SEAL" THAT INTERFACES THE RIM OF THE RING AND THE HEAD SHALL BE COMPOSED OF NEOPRENE RUBBER ASTM D 2000.

4. ALL WELDING SHALL BE MIG (METAL ARC INERT GAS) IN ACCORDANCE WITH THE REQUIREMENTS OF MILITARY AND FEDERAL SPECIFICATIONS MIL-W-45205.

THE TIDE GATE SHALL BE DESIGNED AND CONSTRUCTED TO WITHSTAND A MINIMUM SEATING HEAD OF THIRTY (30) FEET AND SHALL BE ADJUSTABLE (IN

BOTH THE VERTICAL AND HORIZONTAL DIRECTIONS) TO BE FREE FLOWING ON THE UNSEATING HEAD SIDE. THE TIDE GATE SHALL BE PACKAGED IN A

SECURE MANNER TO REDUCE MOVEMENT OR DAMAGE DURING NORMAL SHIPPING.

CONNECTION TO PRECAST CONCRETE ENDWALLS SHALL BE DESIGNED BY PRECAST FABRICATION ENGINEER AND SUBMITTED TO NRCS PROJECT

ENGINEER FOR APPROVAL. FABRICATION ENGINEER SHALL ALSO SUBMIT ANY AND ALL TIDE GATE DESIGN CALCULATIONS TO NRCS PROJECT ENGINEER

FOR APPROVAL. THIS INFORMATION SHALL BE INCLUDED IN THE SUBMITTAL AS OUTLINE ABOVE IN ITEM B.2.B.

TIDE GATE INSTALLATION INSTRUCTIONS FOR CORRUGATED HDPE-S PIPE:

1. CLEAN THE INSIDE TWELVE INCHES AT THE END OF THE PIPE THAT WILL RECEIVE THE TIDE GATE.

2. APPROXIMATELY THREE (3) INCHES FROM THE END, APPLY A DOUBLE BEAD OF SEALANT (SIKA-FLEX OR EQUAL) ALL AROUND THE INSIDE OF

THE HDPE PIPE.

3. SLIDE THE 12 INCH LONG 3/16 THICK SMOOTH ALUMINUM STUB, FLANGED TO MATCH TIDE GATE, COATED WITH MARINE ADHESIVE SEALANT INTO

THE HDPE PIPE.

4. INSTALL SIX (6) 5/8 INCH ALUMINUM BOLTS EVEN SPACED AROUND THE HDPE PIPE AND THROUGH THE ALUMINUM STUB. THE ALUMINUM BOLTS

WILL HAVE FLAT WASHER ON THE HEAD END AND A FLAT WASHER AND LOCKING NUT ON THE THREADED END. BOLTS SHALL BE INSTALLED

WITH THE BOLT HEAD ON THE INSIDE OF THE PIPE.

5. THE ABOVE INFORMATION IS ONLY SUGGESTED INSTALLATION INSTRUCTIONS. CONTRACTOR SHALL BE RESPONSIBLE FOR DETERMINING THE

APPROPRIATE INSTALLATION SEQUENCE/NEEDS IN ORDER TO ENSURE A WATER TIGHT SEAL AND CORRECT FUNCTIONING OF THE TIDE GATE.
