METHOD OF AND APPARATUS FOR CUTTING HOLLOW PRECAST CONCRETE PILES OR THE LIKE

摘要

Hollow precast concrete piles can now be cut in their state driven into the ground to remove their top portion extending above the ground with efficiency and without causing any substantial noise or any damage to the lower major pile portion set in the ground principally by mechanically applying a shearing force to the pile substantially radially in a transverse cross section thereof at the level where the pile is to be cut.
