Abstract

The probe is particularly for compacting soil during civil engineering work, and can have rigid extension tubes, coaxial with the eccentric weights. Passages can be provided to deliver air, water or injection grout to the vibrator probe tip. Internal couplings can be included, allowing damping of vibration and resistance to moments perpendicular to the probe axis. Stretch-resistant flexible extension tubes can be provided, and contain passages supplying the probe and the ground via the probe top. The tubes are supplied continuously to match the rate of advance, the flow being controlled by a jaw.
