PILE WITH SOUND ABATEMENT FOR VIBRATORY INSTALLATIONS

摘要

A noise-attenuating pile comprising a pile driving shoe, an outer tube that engages the pile driving shoe, and an inner member that extends through the outer tube and engages the pile driving shoe, wherein the pile is configured to be installed in the ground with either an impact driver or a vibratory driver that engages only the inner member. The inner member is rigidly connected to the driving shoe, and the outer tube is elastically connected to the driving shoe, such that vibrations from the outer tube is substantially isolated from vibrations in the driving shoe.

1. A pile configured for noise abatement during driving into the ground, the pile comprising:
a pile driving shoe; an outer tube elastically connected to the driving shoe, wherein the elastic connection substantially isolates the outer tube from high frequency vibration of the driving shoe; an inner member that extends through the outer tube and engages the driving shoe defining an annular channel between the inner member and the outer tube, wherein the inner member extends upwardly from the outer tube; and an annular seal disposed near a lower end of the annular channel, wherein the pile is configured to be driven into the ground by a pile driver that engages the inner member without engaging the outer tube.
