Hydraulic Pile Hammers – HPH15000
\nThe most recent development in the Dawson hammer range is the 15K. Unfortunately we have had to comply to the industry standard of using “Energy” for designation. 15K means 15,000kgm of energy. It has the momentum of another hammer of 60,000kgm. This hammer has a drop weight of 12 tonnes and an impact velocity of 5m\/sec.<\/p>\n
This hammer has been designed for all hammer applications. But it also has features which recognise two particular problems:-<\/p>\n
Flushing, drilling.
\nHammers of this size are most commonly used to drive steel pipe piles. When these piles are long and hard ground layers are encountered driving becomes difficult. Big hammers are then required and the wall thickness of the pile has to be increased in order to withstand the higher driving stresses. Cranes and associated plant all become larger and more costly. If it is possible to remove or disturb the soils on the inside of the pile, during pile driving, in order to reduce internal skin friction, much of this additional expense may be avoided. The 15K has been designed with a hole through the middle of the drop weight and anvil to facilitate flushing or drilling. This enables drilling and or flushing to run concurrently with impact driving but without the drill of flushing pipe being impacted.<\/p>\n","protected":false},"excerpt":{"rendered":"
