Zusammenfassung:	A caisson or casing 107 for installing a sheet 102/103 into a ground or underwater location, the caisson 107 having a shaped wall 107.1 which is open for a predetermined length, which is adapted to receive and connect to an excavation means 3 within the confines of the caisson or casing 107. The present also provides a drilling assembly 3 for insertion of a caisson or casing 1, said drilling assembly 3 having two or more expanding drill bits 4 which are adapted to be driven by a drilling or rotation motive device 5, said expanding drill bits 4 being adapted to be arranged with respect to said caisson or casing 1 in use, so as form a hole or bore which substantially conforms to, or substantially overlaps with, the shape of said caisson or casing 1.
