Title (EN) ALL-CONDITIONS TUNNEL BORING MACHINE
(FR) TUNNELIER POUR TOUTES LES CONDITIONS
Abstract:
(EN) A tunnel boring machine is provided comprising a cutter head, a main beam, a first, second, and third shield; and a ground conditioning work zone within the first shield, a gripper assembly, a segment erector arm for lining the tunnel, and at least one propulsion mechanism. The ground conditioning work zone includes at least one probing device for probing the terrain ahead of the cutter head. The first shield is configured to be retracted relative to the second shield to provide access for the ground conditioning work zone to apply at least one ground support device. The at least one propulsion mechanism moves the cutter head, the first and the second shield forward while the third shield and the gripper assembly remain stationary. The ground support devices can include filling a hole with a ground conditioning agent; and placing a bolt, ring beam, mesh, or shotcrete in/on the tunnel wall.
(FR) La présente invention porte sur un tunnelier comprenant une tête de coupe, un longeron principal, un premier, un deuxième et un troisième blindage ; et une zone de travail de conditionnement du sol dans le premier blindage, un ensemble grippeur, un bras érecteur de segments pour cuveler le tunnel, et au moins un mécanisme de propulsion. La zone de travail de conditionnement du sol comprend au moins un dispositif de sondage pour sonder le terrain devant la tête de coupe. Le premier blindage est configuré pour être rentré par rapport au deuxième blindage pour offrir un accès pour que la zone de travail de conditionnement du sol applique au moins un dispositif de soutènement. Le ou les mécanismes de propulsion déplacent la tête de coupe, le premier et le deuxième blindage vers l'avant tandis que le troisième blindage et l'ensemble grippeur restent stationnaires. Les dispositifs de soutènement peuvent comprendre le remplissage d'un trou avec un agent de conditionnement de sol ; et le placement d'un boulon, d'un cintre, d'une mèche ou de béton projeté dans/sur la paroi de tunnel.
