摘要： A moling apparatus (2) comprises a housing (4) having a head (8) for penetrating ground, an anvil (16) disposed in the housing connected to the head, a hammer (18) disposed in the housing and spaced therefrom by resilient restraint means (20). A vibrator unit (42) 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 resilient means and impact the anvil thereby driving the head through the ground, said apparatus being operable at or between said modes.

摘要： The invention relates to a method for monitoring the condition of a ground anchorage (2) in a bore in a ground formation (1) at a site, which method comprises: securing a means for monitoring frequency response spectra (10) to said ground anchorage, applying to said ground anchorage an impulse load (11) of a predetermined value, recording the signature of the frequency response spectra, and comparing said signature with a reference signature from the site, thereby to obtain an indication of the integrity of the ground anchorage in the formation.

摘要： A ground anchorage testing arrangement having an impulse imparting apparatus connectable to a ground anchorage tendon (20) or element thereof to be tested, the impulse imparting apparatus comprising an attachment means (22) for attachment to the ground anchorage tendon (20), a movable mass (31), a guide (28, 34) for guiding movement of the mass in the direction substantially aligned with the axis 0 of the ground anchorage to be tested and a drive means for imparting a driving force to move the mass in said direction (not shown). A method of assessing the integrity of ground anchorages, the method comprising the steps of (a) imparting a load impulse to a ground anchorage tendon to be tested, (b) monitoring the vibrational response signal of the anchorage to the imparted load impulse, (c) conditioning the vibrational response signal and (d) applying the conditioned vibrational response signal to an artificial neural network.
