(FR) SYSTÈME ET PROCÉDÉ DE MISE EN PLACE DE CAISSON AMÉLIORÉS
Abstract:
(EN) The present invention 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).
(FR) La présente invention concerne un ensemble de forage (3) pour l'insertion d'un caisson ou boîtier (1), ledit ensemble de forage (3) ayant au moins deux trépans expansibles (4) qui sont conçus pour être entraînés par un dispositif moteur de forage ou de rotation (5), lesdits trépans expansibles (4) étant conçus pour être agencés par rapport audit caisson ou boîtier (1) lors de l'utilisation, de manière à former un trou ou un passage qui épouse sensiblement, ou chevauche sensiblement, la forme dudit caisson ou boîtier (1).
