<p>A vibration-damping arrangement intended to be placed in a slot-like shaft or trench in earth layers, or in water masses, wherein the arrangement includes a flexible container (1) which is pressurised by a gas in its operative state, and wherein the container has an associated gas generating device (2) which is adapted to generate a predetermined gas volume in the container at a given time delay. The vibration-damping arrangement can be used to reflect the propagation of vibrations or to restrict the occurrence of the quicksand phenomenon in water-containing ground in the event of cyclic pressure variations, e.g. in earthquake or landslip conditions. The arrangement can be conveniently combined with means for draining water from the ground in the near proximity of the container.</p> |
