The cushion also presents attenuation from the blow during driving, cutting down tensile forces performing on the pre-stressed pile as it truly is driven. Pile cushions are provided in many thicknesses and sizes to accommodate the pile as well as the push cap, and are determined by the driving disorders as dictated by the size from the hammer as well as soil. As Each individual venture is different, so will be the cushions distinctive to the particular undertaking at hand. Cushion demands are finest based on wave equation analysis, which requires into consideration the particulars of the pile, hammer traits and also the soil composition.
