Abstract
PURPOSE: To stabilize a poor sticky subsoil treated by draining water to a drain layer with a compressed air forced through a water resistant material previously packed into a casing after the casing vertically erected is vibrated to separate the water in the surrounding subsoil.
CONSTITUTION: A sandy drain layer 2 is provided on a poor sticky subsoil 1, with a bottom lid 3' pivoted at the lower end, a casing 3 arranged vertical is vibrated to separate water from soil particles in the surrounding subsoil 1. Then, a netlike cylinder body 4 having a weight 4' at the lower end hangs down in the casing 3 and a water permeable material 5 such as sand is packed into the cylindrical body 4 vibrating the casting 3. Compressed air is forced into the casing 3 at the upper end thereof vibrating it and the water is drained to the layer 2 along the circumference of the casing 3 pulling out the casing 3 alone. The water permeable water is left in the subsoil 1 as a water permeable pillar. Therafter, one or more of water permeable pillars 7 are formed near the water permeable pillar to stabilize the subsoil 1.
