Abstract: In cushion assembly of pile cap used to drive a pile into the ground with a hammer, anvil pad (7) composed  of  synthetic  resin with elastic modulus of 50,000 to 800,000 psi  and  with  recovery coefficient of 0.2 to 0.9 is arranged on slanted groove (2) of the top of cap (1). Between the pile (3) and  the  cap  (1)  synthetic resin with the same range of material property as above  mentioned but having different  intrinsic  vibration,  elastic  modulus  and recovery coefficient is composed. Cushion (6) with air-vent (5) is placed at the center of the assembly. Anvil pad  (7)  and  cushion (6) composed of  a  compound  of  themoplastic  and  thermosetting resins and a sort of rubber.
