REMOVABLE FORMS SPEED CONCRETING OF MOBILE RIVER TUNNEL TUBES

SPECIALLY FABRICATED STEEL FORMS THAT CAN BE QUICKLY AND EFFICIENTLY TRANSFERRED BETWEEN FLOATING TUBE SECTIONS ARE FORMING THE CONCRETE TUBES THAT WILL BECOME A HALF-MILE TUNNEL UNDER THE MOBILE RIVER IN ALABAMA. THE TWIN STEEL TUBES SERVE AS BOTH A WATERPROOF LINER FOR THE TUNNEL AND AN OUTSIDE FORM FOR THE CONCRETE LINING OR STRENGTH RINGS. THEY ARE BUILT UPRIVER AND FLOATED TO THE OUTFITTING YARD WHERE THE CONCRETE LINING IS PLACED AND COMPLETELY FINISHED EXCEPT FOR THE INTERIOR TILE. /R&S/
