Abstract

PURPOSE:To prevent the liquefaction of foundation ground by avoiding the generation of excessive void water pressures at the time of earthquake by driving a given number of drain pillars consisting of a reinforced water-permeable concrete pipe and a water-permeable wall into the foundation ground. CONSTITUTION:In a foundation ground B to support a structure A on the earth's surface, pits 11 are drilled in given places surround foundation piles 4 and then water-permeable concrete pipes 1 reinforced with iron bars 5 are set. Then, water-permeable wall-forming materials 12, e.g., gravel, fine stones, slags, etc., are charged into the apertures between the reinforced water-permeable concrete pipes 1 and the pits 11 to form a water-permeable wall 2 in order to build drain pillars 3. By this, excessive void water pressures to be generated at the time of earthquake are dissipated into the foundation ground B and the liquefaction of the foundation ground B and the surrounding ground of the foundation piles 4 can be prevented.
