This invention relates to the solidified method of weakened grounds for the purpose of homogenizing and hardening of weakened soil. The object of this method is that the solidifing agent penetrates the all of weakened grounds and hardens them in order to make hard grounds. When the solidifying agent is poured into the grounds, multi-pipes are used so that more than two solidifing agents are poured into grounds. First, one solidifing agent which is solidified within 30 sec. and formed the solidified layer (D) is poured into the grounds, and the other solidifing agent which is solidified beyond a minute is poured into grounds though multipipes and forms the solidified layer(E), and the grounds are hardened.
