Abstract

PURPOSE:To prevent the sinking of ground due to consolidation and to improve the earthquake-proof quality by a method wherein vertical gridwork walls and a top plate are fixed in one body by injecting a solidifying agent, mixing and stirring in the weak ground at the bottom of the water and thereby the poor soils are enveloped by the gridwork. CONSTITUTION:When a caisson or cellular revetment, for example, are constructed on the soft gound at the bottom of water, solidifying agent are poured into the weak ground to form vertical gridwork walls constituted by main vertical walls P and subsidiary vertical walls P and cast then a top plate Q, so that these vertical walls and the top plate are fixed in one body rigidly. As a result, the weak ground enclosed in this way is held back from its movements and sinking due to consolidation is prevented and also its earthquake-proof quality is improved.
