HOLLAND EVALUATES HYDROVALVING CONCRETE

HYDROVALVING, A NEW DEVELOPMENT IN UNDERWATER CONCRETE PLACING, IS BRIEFLY DESCRIBED. THE METHOD USES A FLEXIBLE TUBE AND A POURING TUBE WITH A RIGID CYLINDRICAL SHIELD AT THE BOTTOM. THE WATER PRESSURE FORCES THE FLEXIBLE WALLS AGAINST EACH OTHER WHEN THE PIPE IS EMPTY. THE CONCRETE MOVES DOWNWARD SLOWLY UNDER ITS OWN WEIGHT. CORES WERE DRILLED FROM CONCRETE PLACED UNDER WATER BY VARIOUS METHODS AND SUBJECTED TO COMPRESSIVE STRENGTH TESTS. A COMPARATIVE STUDY IS MADE OF THE COSTS OF METHODS OF PLACING CONCRETE UNDERWATER. /TRRL/
