Method and apparatus for increasing bearing capacity of soft soil and constructing cutoff wall

摘要: A method and apparatus for forming a subsurface zone having an increased bearing capacity in preselected area of relatively soft soil is disclosed. liquefaction generator provided the form plurality interconnected perforated pipes grid pattern which substantially extends over area. Air water under pressure are supplied to while allowing it sink within subterranean layer hard or rock. The air continually until above state thereafter hardenable material and/or rock fragments added liquified generator. Thereafter, mixed allowed solidify period time. For sites containing areas compacted material, cutters may be attached further break up material. also applied construction cutoff walls with without embedded, vertical, moisture impervious membranes.
