Beschreibung
Zusammenfassung:	Compositions and methods useful in creating boreholes, tunnels and other excavations in unstable soils and earth formations, especially those composed partially or wholly of sand, gravel or other granular or permeable material are disclosed. The fluids include a polymer, and a soluble silicate ion source. The fluids of the invention, when used according to the methods of the invention, have unique dual functionality as excavating fluids and as earth-grouting or soil-hardening compositions. L'invention concerne des compositions et des procédés utiles pour réaliser des trous de forage, des tunnels et d'autres excavations dans des sols et des formations géologiques instables, en particulier ceux qui se composent, en totalité ou en partie, de sable, de gravier ou d'autres matières granulaires ou perméables. Les fluides renferment un polymère et une source d'ions silicate soluble. Lorsqu'on utilise les fluides de l'invention conformément aux procédés de l'invention, ceux-ci présentent une double fonction originale de fluides d'excavation et de compositions pour injection de remplissage ou durcissement du sol.
