Abstract:
A system enabling a user to remotely apply a load impulse to a ground anchorage tendon (2, 20) or element thereof to be tested, the system comprising:an impact receiver (8, 25) securable relative to the tendon or element thereof so as to operatively transmit mechanical energy therebetween; a tubular member (34), associated with the impact receiver, encircling the tendon or element thereof and restrained against axial motion relative thereto; an annular mass (31), disposed coaxially with the tubular member, the mass being capable of sliding movement along the tubular member and being guided thereby towards the impact receiver from an initial position spaced therefrom; power means (17, 32,33), actuatable remotely from the tendon or element thereof, for applying a particular motive force to the mass to cause the mass to move from said initial position and to collide with the impact receiver thereby generating the load impulse and operatively transmitting it to the tendon or element thereof; and sensor means (9) for detecting the vibrational response of the tendon or element thereof to the load impulse and for generating electrical signals indicative of the response.
