A method for forming a solidified granular material (15), in which granules (16, 17) are charged into a tubular frame member (11) and then heated together with the frame member, to solidify the granules. The granules include a mixture of first granules (16) and second granules (17), each of which second granules has a thermoplastic resin shell enclosing a solid or liquid which expands by vaporization. The mixture is charged into the frame member and heated together with the frame member. The heating causes the second granules (17) to expand and the surfaces of the second granules to melt for bonding with the first granules (16). The mixture, upon cooling, becomes a solidified granular material (15), filling the frame member with no space therebetween.
La présente invention concerne un procédé de fabrication de matériau (15) granulaire solidifié, dans lequel des granulés (16, 17) sont chargés dans un cadre tubulaire (11) puis chauffés ensemble avec ce cadre de façon à solidifier ces granulés (17). Ces granulés comprennent un mélange de premiers granulés (16) et de seconds granulés (17), chacun de ces seconds granulés possédant une coque de résine thermoplastique enfermant un solide ou un liquide qui se dilate par vaporisation. Ce mélange est chargé dans le cadre et chauffé avec ce cadre. Le chauffage entraîne la dilatation des seconds granulés (17) et la fonte des surfaces de ces seconds granulés de façon qu'ils se collent aux premiers granulés (16). Ce mélange lors du refroidissement devient un matériau granulaire (15) solidifié qui remplit le cadre sans laisser d'espace entre les éléments.
