LEADING THE TREND TOWARDS DISCREET PILING

THE PILEMASTER, WHICH CAN QUIETLY KNOCK SHEET PILES INTO THE GROUND, IS DESCRIBED. PILES ARE PUSHED INTO THE GROUND BY HYDRAULIC JACKS. THE REACTION FROM THE JACK PUSHING A PILE IS TAKEN BY FRICTION BETWEEN THREE OTHER PILES AND THE GROUND. A PANEL OF 7 OR 8 PILES MUST BE DRIVEN IN ONE OPERATION. THE SYSTEM ONLY WORKS IN COHESIVE GROUND BUT PRETRENCHING TECHNIQUES OVERCOME THIS PROBLEM. FILL MATERIAL IS DUG OUT UNDER BENTONITE AND REPLACED WITH A MIXTURE OF SAND, PORTLAND CEMENT AND BENTONITE. USE OF THE PILEMASTER AT THE ANGEL COURT SITE IN LONDON IS DISCUSSED. 486 PILES ARE BEING USED TO SUPPORT THE BASEMENT EXCAVATION FOR A NEW OFFICE DEVELOPMENT. THE PILEMASTER CAN MEASURE RESISTANCE TO PENETRATION, AND EXTRACT PILES. PRETRENCHING COSTS found10/SQM. THE PILEMASTER HAS A NOISE LEVEL OF 70DB AT 1.5M SO IT IS AN ECONOMIC PROPOSITION WHERE NOISE REDUCTION IS REQUIRED.
