AN OPTIMIZATION STUDY OF AN EXPLOSIVE-DRIVEN PILE

The propulsion of metals by the detonation of explosives in direct contact with them and propulsion effectiveness of various explosives for such purposes was studied. The results of these studies were applied to the design and evaluation of explosives systems for pile driving. It was determined that...

Description
Summary:The propulsion of metals by the detonation of explosives in direct contact with them and propulsion effectiveness of various explosives for such purposes was studied. The results of these studies were applied to the design and evaluation of explosives systems for pile driving. It was determined that piles with external grooves along their entire lengths which are driven by the detonation of high explosives upon the lips of these grooves are not as effectively propelled as those which are driven by explosive 'hammerheads' on top of the piles. The results indicate that long, heavy-walled steel piles may successfully be driven into ordinary and frozen ground by the appropriate design and use of such explosive hammerhead systems. (Author)
