PILE REAMER WITH SPOIL CONTAINER

摘要

The present application relates to a tool having a cutting means (25, 26) for enlarging a portion of an underground pile shaft. The tool is provided with a collecting means (32) which is disposed below the cutting means in order that spoil generated when performing a cutting action on ground material surrounding the pile shaft can be collected. The size of the collecting means is adjustable thereby allowing the volume of spoil which may be accommodated by the collecting means to be varied. A compacting device (49, 50) for compressing the spoil collected in the collecting means may also be provided for reducing the volume of the spoil.
