Abstract

POUR INJECTER UN COULIS DE SILICATE DE SODIUM DANS UN SOL, TEL QU'UN SOL SABLONNEUX A CONSOLIDER, ON INTRODUIT SEPAREMENT, SOUS UNE PRESSION ELEVEE, UNE SOLUTION AQUEUSE DE SILICATE DE SODIUM ET DU BIOXYDE DE CARBONE DANS UN SYSTEME D'INJECTION DE COULIS A DOUBLE CONDUITE 1, 2 COMPORTANT UN MELANGEUR INCORPORE AYANT UNE LONGUEUR M, AGENCE A PROXIMITE DE L'ORIFICE DE SORTIE DU SYSTEME QUI COMPORTE AUSSI UNE SOUPAPE DE RETENUE 6 REGLEE AU MOYEN D'UN RESSORT 7 POUR S'OUVRIR AU-DELA D'UNE PRESSION PREDETERMINEE DE MANIERE A PERMETTRE L'INJECTION A FORCE DUDIT COULIS DANS LE SOL A CONSOLIDER.TO INJECT SODIUM SILICATE GROUT INTO A SOIL, SUCH AS A SANDY SOIL TO BE CONSOLIDATED, IS INTRODUCED SEPARATELY, UNDER HIGH PRESSURE, AN AQUEOUS SOLUTION OF SODIUM SILICATE AND CARBON BIOXIDE IN A SLURRY INJECTION SYSTEM WITH DOUBLE DUCT 1, 2 INCLUDING AN INCORPORATED MIXER HAVING A LENGTH M, AGENCY CLOSE TO THE OUTLET OF THE SYSTEM WHICH ALSO INCLUDES A CHECK VALVE 6 SET BY MEANS OF A SPRING 7 TO OPEN BEYOND D 'A PREDETERMINED PRESSURE SO AS TO ALLOW FORCED INJECTION OF THE GROUT INTO THE SOIL TO CONSOLIDATE.
