Abstract
A ground treatment device ( ) is weighted to provide ground treatment by dropping the device onto the ground. The device ( ) has a relatively narrow nose ( ) which provides, in use, the point of first contact with the ground. The device widens away from the nose ( ), over a portion ( ). A clevis arrangement ( ) allows the device ( ) to hang from a cable ( ), to allow the device ( ) to be raised by a crane, before dropping. A shoulder ( ) projects outwardly and allows calibrated measurement of the degree of compaction achieved in the ground. Variations of the device ( ) are described, together with apparatus for use in lifting and dropping the device, and methods of using the device.
