Abstract: The present invention concerns an isolation element for the isolation of vibrations and/or heat, which propagate/s in a medium such as soil, as well as the application of isolation element in an isolation arrangement. The isolation element is characterized by a rectangular plate-shaped block (1) with one or several on one or both of the two side surfaces attached cushion-shaped bodies (2). The isolation arrangement is characterized by a trench (7) in the ground, in the bottom of the trench preferably vertically anchored guide rods (8) placed in a row, in the trench poured stabilizing slurry (10) as well as on the guide rods (8) threaded and from the bottom of the trench (7) to the orifice and preferably along the whole length of the trench on top of each other and/or next to each other stacked isolation elements (9) placed on their edges.

Abstract: Soil nails are entrained into the ground by vibration of a beam or compacn probe into the ground and remain behind when the beam is removed to transfix a friction soil layer and anchor it to the cohesion soil layer.

Abstract: The present invention relates to a method and an arrangement for influencing the interaction between a layer of earth and a structure situated in association with the layer of earth. What is characteristic of the invention is that a casing filled with a medium and introduced into a layer of earth is introduced into a material surrounding the casing, which material preferably consists of a bentonite or a bentonite mixture.

Abstract: The present invention relates to a method and apparatus for compacting by vibrations a soil stratum with the aid of at least one vibration-transferring member (2) which may be driven into the soil stratum, said member transferring vibrations from a vibration generating means (1) to the soil stratum. In accordance with the invention the axial extension of the member (2) is variable both before and in conjunction with the vibration compaction by the member being implemented such as to be resilient, elastic or flexible.

Abstract: The present invention relates to an arrangement in vibration isolation or vibration damping of vibrations generated in a medium, said arrangement including one or more separate or connectable diaphragms (1) immersible in the medium. In accordance with the invention the diaphragm (1) comprises at least two layers, an outer (2) and inner (3) diaphragm casing. One of the inner diaphragm casings has cells or ducts. An outer support layer (not shown) may constitute an integrated part of the outer diaphragm casing (2) or form a further support pad arranged outside the outer diaphragm casing. The diaphragm also has heat-insulating and pressure-reducing properties.
