Pipe ramming is a non-steerable system of forming a bore by driving a steel casing, usually open ended, using a percussive hammer from a drive pit. The soil may be removed from an open-ended casing by augering or jetting with water or compressed air.
On
site preparing for the ramming of steel pipe in lengths. Length of steel
sleeve can be from 3, 6 or 8 metre lengths. Extra sections can be welded
on to cover desired length. The length of steel sleeve you select depends
on the amount of space available to set up the preparation trench. The
preparation sending pit must be of stable bottom either by pouring a concrete
base or by spreading a bed of screenings to support the steel sleeves
as they are being hammered into position.
