(EN) METHOD AND ARRANGEMENT FOR PREVENTING MOVEMENT OF STRUCTURE
(FR) PROCÉDÉ ET AGENCEMENT PERMETTANT D'EMPÊCHER LE MOUVEMENT D'UNE STRUCTURE
Abstract
(EN)
The invention relates to a method and arrangement for preventing movement of a structure. An expansion element (6) is arranged in soil. A material which expands inside the expansion element (6) as a consequence of a chemical reaction is injected into the expansion element (6). The expanded expansion element (6) remains in its place in the soil owing to friction and cohesive forces, and it is fastened to the structure (2), the expansion element (6) thus preventing movement of the structure (2).
(FR)
L'invention concerne un procédé et un agencement permettant d'empêcher le mouvement d'une structure. Un élément d'expansion (6) est agencé dans le sol. Un matériau qui se dilate à l'intérieur de l'élément d'expansion (6) suite à une réaction chimique est injecté dans l'élément d'expansion (6). L'élément d'expansion dilaté (6) reste en place dans le sol en raison du frottement et des forces de cohésion, et est fixé à la structure (2), l'élément d'expansion (6) empêchant ainsi le mouvement de la structure (2).
