Abstract

The machine has an open topped shield incorporating incrementally advancing, jack (12) driven, longitudinally orientated lateral sheeting (14) with leading cutting edges, a jack thrust frame (13), a sub-frame or chassis or inverted trapezoidal section (11), a power source with a front excavating jib (6, 23) and aft lifting jib (7), an excavation discharge belt (3) and an overhead cab (5) for remote control of all functions. Jacks are used to thrust advance the sheeting and pull advance the frame after the excavation phase and pipes (7) are laid in the wake of the machine as it proceeds.
