Buckets are recommended for drilling layers of soil and rock in presence of water and when the drilling technology uses bentonite. As result of different job site reports, buckets are designed in two different ways: · Single opening: suitable for ne grained soils and bored pile up to diameter 1000 mm. They are particularly indicated in case of casings application and coarse gravel. · Double opening: suitable for ne grained soils and bored pile over diameter 1000 mm. They are particularly indicated for secant pile walls Designed with a rotating bottom to load drilled material; a vent pipe making...
