Abstract
The casing for consolidating granular subsoils by injection from above has self closing outlets (2) along it. The casing seals without packing and is suitable for installing horizontal barriers beneath deep foundations. A valve action is used to close the outlets, and the assembly comprises a head-casing (1') demountably coupled (10) to an injection-casing (1''). The injection agent is fed through the head-casing (1'). An extendable sleeve (9) is located externally at each outlet together with an internal sliding sleeve (4), and an internal sliding sleeve (4'') is also immediately above the coupling (10). The bore of a sleeve (4) is reduced relative to that of the sleeve (4') above, and spherical plugs (13) pertaining to a sleeve (4) pass through the sleeve (4') above. A plug (13) is dropped from above to settle on the inlet to a sleeve (4). The sleeve (4) is thus displaced permitting the agent to pass through the outlet (2) concerned.
