CENTRIFUGALLY SPUN PRECAST CONCRETE CYLINDER PILES STRUCTURAL SOLUTIONS FOR THE MARINE ENVIRONMENT ADVANTAGES: > LARGE BENDING MOMENTS > LONG UNSUPPORTED LENGTHS > LARGE CO<strong>MB</strong>INED AXIAL LOADS AND BENDING MOMENTS > HOLLOW CROSS SECTION ALLOWS FOR EASY PILE TO CAP CONNECTIONS > STREAM AND WIND DRAG ARE REDUCED BY THE ROUND SHAPE > DENSE CONCRETE SURFACE, LOW WATER CEMENT RATIO AND REDUCED CHLORIDE PERMEABILITY DUE TO CENTRIFUGAL CASTING Cylinder piles; a cost effective, alternative solution to conventional steel, drilled shaft, round static cast and square prestressed concrete piles.

The Inner Harbor Navigation Canal Barrier By: Patricia Barnes, Bayshore Concrete Products The project is massive; the timeline aggressive: The U.S. Army Corps of Engineers is building a state-of-the-art 1.5 mile long storm surge barrier with three navigable gates across the Gulf Intracoastal Waterway and the Mississippi River Gulf Outlet. This is the largest design-build project in Corps history and will be the largest project of its kind in the world. This barrier is designed to protect lives, land and property from the type of flooding that devastated the New Orleans area during Hurricane Katrina. Officially named the Inner Harbor Navigation Canal Surge Barrier, the project is scheduled to be complete by June 2011. After months of scientific and engineering analysis comprised of more than 150 nationally known experts the best design approach was finalized and the project awarded to Shaw Environmental and Infrastructure in December of 2008. Work began quickly in 2009 with crews working around the clock this summer to maintain the tight schedule. Shaw Environmental contracted Bayshore Concrete Products of Cape Charles, Va., and Gulf Coast Pre-Stress Inc. of Pass Christian, Miss., to provide the 66-inch diameter cylinder piles required to construct the surge barrier. Bayshore Concrete and Gulf Coast Pre-Stress are the only two pre-cast, pre-stressed producers to make centrifugally spun cylinder piles in the United States using the CEN-VI-RO method. Spun piles were the technology of choice because an extremely dense concrete, much denser than obtainable by ordinary casting methods, results from the spinning process employed in the manufacturing of these piles. The cylinder piles require no field assembly as they are fully assembled at the Bayshore Concrete and the Gulf Coast Pre-Stress plants Of particular significance is the great structural strengths which permits combined axial loads and bending moments of considerable magnitude. Pre-stressed concrete piles have many inherent qualities that insure a long life with no maintenance costs - they are highly resistant to corrosion and to damage by water action. These spun concrete piles are categorized as a green product and these cylinder piles have a life expectancy of at least 100 years. The storm surge barrier is comprised of 1,267 cylinder piles. Each pile is 144 feet long, 66 inches in diameter with a six-inch wall thickness and 32 post tensioned tendons. Each pile is made up of nine 16-foor sections that are stressed and then grouted. The cylinder pile sections are manufactured on a CEN- • Q4 • 2009 63
