Increasing of the Efficiency of Extraction of Elements from Soil by a Tubular Diesel Hammer

Abstract

For the extraction of piles, sheet piling, and casings from soil, we propose new decisions for the devices that make it possible to increase the machine time of using diesel hammers due to the extension of the field of their application. The efficient combination of the dynamic action by shock pulses and static extraction forces directed upward in the direction of pulling of elements from the soil makes it possible to use tubular-type diesel hammers not only to deepen but also to extract elements from soils.
