| 24" Octagonal Driving |
 24" oct. Sure-Lock Pile Splice - Port of Oakland, Berth 57, 2001 Bottom pile segment of 80 ft. with Female splice half lofted.
|
 24" oct. pile, Male and Female splice ends on 80 ft. pile segments
|
| 24" & 30" sq. pile splice Casting & Driving |
 30" sq. Sure-Lock Splice - Male & Female parts in casting bed, splice anchor rebar screwed into plates inside spiral.
|
 Bottom Pile Segment - with Female Splice end, showing recess for square Male Plate.
|
 30" sq. Sure-Lock Splice - Top pile segment with Male main plate Splices were for FDOT bridge project
|
 24" sq. Sure-Lock Pile Splice - FDOT St. John's River Bridge. Top pile segment lowered so splice plates fit together.
|
 24" sq. Sure-Lock Splice - when splice plates meet evenly, 4 high-strength steel locking bars are inserted through side holes into the groove space in the Male & Female plates. The bars are shear keys, and after insertion, are held from backing out by plugs screwed into the holes in the main plate. The main plate thickness, locking bars, rebar size are designed to conservatively meet strength requirements in compression, bending and tension. Calculations are provided for approval.

 Top pile segment with circular Male plate, loften, cleaned off, and ready for splicing.
|
 18" sq. Splice for FDOT bridge widening project near Orlando. Bottom segments with Female splice half driven first.
|
 18" sq. Splice for FDOT bridge - After mating the splice halves, 2 high-strength steel locking bars are driven into the matching Male and Female splice grooves with sledge or Rivetbuster.
|
 16" sq. Texas DOT wharf - 2 locking bars driven into the splice grooves to form a circular shear key - in less than two minutes.

 16" sq. Top Segments to 14" sq. Bottom Segments - San Francisco - Mission Bay Project
|
 Use of 16" sq. top segment 65 ft. long with reinforcement for higher moment capacity, combined with 14" sq. 100 ft. long bottom segments saved on piling costs. The Sure-Lock has also been used to splice 20" sq. top segments to 16" oct. bottoms.

 5000 - 16" octagonal splices for Honolulu Keehi Interchange. 3 - 90 ft. segments per 270 ft. long pile with 3" center tube for verification of pile integrity.
|
 650 - 20" octagonal piles for Kauai Pier 3. Splices connected 2 - 100 ft. segments for 200 ft. piles. Bottom segments shown with driving plates. Second segments then spliced and driven with a production rate of 10 piles per day.
