The cushion also provides attenuation with the blow for the duration of driving, reducing tensile forces acting over the pre-stressed pile as it can be pushed. Pile cushions are presented in several thicknesses and measurements to support the pile along with the push cap, and so are determined by the driving situations as dictated by the dimensions with the hammer plus the soil. As Just about every job differs, so tend to be the cushions exceptional to the particular venture at hand. Cushion specifications are best based on wave equation Investigation, which can take into account the particulars on the pile, hammer traits and also the soil composition.
