PURPOSE: To easily construct the ground by laminating resin strings in the shape of a hollow column inside a plurality of well holes installed on the a sand ground and welding the connected parts of the strings and burying a waste water material whose outer peripheral surface is wound with filter material. ;CONSTITUTION: A well hole 2 whose size and depth are specified is bored on a sand ground 1 at a specified span. In addition to the hole, resin strings are laminated in the shape of a hollow column in a curled state where the connected parts of the strings are welded with each other. A filter material 6 is wound around the outer peripheral surface, thereby forming a waste water material whose porosity exceeds 80%. The waste water materials 3 are buried into the well hole 2 respectively.;COPYRIGHT: (C)1994,JPO&Japio
