Installation of a Round Hollow Blunt Pile

The article describes technological operations of the installation of a round hollow driven (jacked) open end pile with the widened base from pudded rigid earth material in weak waterlogged soils mainly. Main technological operations of the pile installation includes insertion (driving) of the pile with the end closed with a shoe-puncher at the set depth with a pile driver or jacking unit; insertion (driving) with an inventory guide pipe-stem with a changeable end of the shoe-puncher in the ground of the base with formation of a cavity under the pile end; installation of a shoe-widener in the inner cavity of the shoe-puncher with layered filling of rigid ground material over it with its compaction in a set volume or up to the failure with the guide pipe-stem tip with formation of the broaden base; immersion (driving) of the pile in the widened base with increasing its bearing capacity.
