Sealing and consolidating water- or gas-permeable areas in ground - involves mixing sealing and consolidation materials with gas and injecting into ground etc. using probes

摘要

Sealing materials (a) are mixed with gaseous carrier mediums. They are blown into the permeable ground areas via one or more injection probes, and are settled in the zones to be sealed. The carrier gas consists of compressed air, nitrogen, or carbon dioxide. Suitable inclination and depth of the injection probes permits the mixed material/gas flow to be directed, so that permeable areas at different depths can be reached and consolidated. The sealing material consists of finest cement, with granulation of under 16 m, pref. mainly under 10 m, esp. under 8 m. USE/ADVANTAGE - Sealing and consolidating natural ground, rocks, earth and stone constructions, having fissures, cracks, erosions, etc. using simplified and non-destructive method.
