The cushion also gives attenuation on the blow all through driving, decreasing tensile forces acting within the pre-stressed pile as it truly is pushed. Pile cushions are furnished in several thicknesses and dimensions to support the pile as well as travel cap, and they are determined by the driving situations as dictated by the size from the hammer and also the soil. As Every undertaking is different, so will be the cushions special to the particular project at hand. Cushion requirements are best based on wave equation Examination, which normally takes into consideration the particulars of the pile, hammer properties plus the soil composition.
Hammer cushions are furnished principally to safeguard impression hammers from destructive forces in the course of Procedure and to permit the utmost Advantages of micro piles amount of useable Strength to generally be transmitted for the pile while avoiding detrimental Power from remaining rebounded towards the hammer.

Brands, in the design in their hammers, make engineering conclusions concerning the amount and type of cushion required for the various models of their products line. Unique styles and dimensions of cushioning, after established, are provided for in attachments to The bottom of your hammer, specifically underneath the point of effect and usually in conjunction with the travel cap design and attachment.
