Abstract: A moling apparatus comprises a housing having a head for penetrating ground, an anvil in the housing connected to the head, and a hammer in the housing and spaced therefrom by a spring. A vibrator unit is spaced from the hammer and arranged to transfer vibration to the housing and the hammer. In a first mode of the apparatus, vibration transmitted to the housing causes fluidization of the surrounding ground to allow progressive penetration of the apparatus. In a second mode, the braking effect of the ground on the head causes the hammer to move against the spring and impact the anvil thereby driving the head through the ground, the apparatus being operable at or between each mode.

Abstract: A method and apparatus for monitoring the condition of a ground anchorage including a tendon arranged in a bore in a group formation at a site is characterized by detecting the vibrational response signature of the anchorage to an impulse load. The vibrational response signature to the impulse is recorded and compared with a reference signature from which any changes in the integrity of the anchorage can be determined.
