Abstract

PURPOSE: To arrange so that a lime mixed soil column of a desired diameter may easily be formed by injecting an aqueous calcium hydroxide solution into a surround soil while pulling out an injection tube inserted into a weak ground moved vertically if necessary.
CONSTITUTION: An injection tube 1 introduced into a weak ground is pulled out while being moved vertically according to necessity and then an aqueous calcium hydroxide solution is injected into a surrounding soil from the jet nozzle 2 on the nose of the injection tube to form a lime-mixed soil column 4 of a required diameter. A sand drain body 5 is provided in this lime-mixed soil column 4.
