Compaction grouting<\/h1>\n

[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/1″][vc_column_text]DESCRIPTION DE LA TECHNOLOGIE<\/u><\/strong><\/p>\n

La technologie d\u2019injection de m\u00e9langes de compositions diverses, principalement \u00e0 base de ciment a pour but d\u2019am\u00e9liorer ou de modifier les propri\u00e9t\u00e9s m\u00e9caniques telles que la r\u00e9sistance et la d\u00e9formation ainsi que les propri\u00e9t\u00e9s hydrauliques (perm\u00e9abilit\u00e9) des sols, ou convient pour le remplissage des cavit\u00e9s existant dans la nature.<\/p>\n

Il s\u2019agit en tout cas d\u2019injections \u00e0 basse pression qui peuvent \u00eatre effectu\u00e9es\u00a0:<\/p>\n

– par le biais de tiges \u00e0 manchettes, c\u2019est-\u00e0-dire de tubes valve apr\u00e8s avoir for\u00e9 dans le sol, qui sont inject\u00e9s au cas par cas et de fa\u00e7on r\u00e9p\u00e9titive\u00a0;<\/p>\n

\u2013 par le biais du compactage du sol (COMPACTION GROUTING) en cr\u00e9ant un bulbe de m\u00e9lange tr\u00e8s visqueux au frottement interne \u00e9lev\u00e9 afin de cr\u00e9er dans le sol un effet de densification par compactage des particules.<\/p>\n

Le compaction grouting est r\u00e9alis\u00e9 par forage dans le sol et par extraction ult\u00e9rieure, par \u00e9tapes successives, avec injection simultan\u00e9e du m\u00e9lange.<\/p>\n

Le compaction grouting convient aux sols d\u00e9formables (sables limoneux, sables limoneux-argileux, limons sableux, limons argileux) en nappes comme dans le cas de la liqu\u00e9faction des sables par des tremblements de terre.della miscela.
\nI terreni adatti per il compaction grouting<\/strong> sono quelli deformabili ( sabbie limose, sabbie limo-argillose, limi sabbiosi, limi argillosi) in falda come nel caso della liquefazione delle sabbia da eventi sismici.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/1″][vc_gallery el_id=”gallery-139086″ medias=”136,139,137″ gutter_size=”3″ screen_lg=”1000″ screen_md=”600″ screen_sm=”480″ images_size=”four-three” single_overlay_opacity=”50″ single_padding=”2″][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":"
