Title:
FLUIDIZATION TREATMENT METHOD
Document Type and Number:
Japanese Patent JP3144321
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of efficiently, quickly and economically carrying out work with excellent strength at a low cost.
SOLUTION: In a fluidization treatment method, fluidization treated soil obtained by mixing water and hardener with excavated soil is poured into an excavated hole locating a buried pipe therein to fill. In that case, all fluidization treated soil filling parts are filled with fluidization treated soil containing general hardener, and then, quick hardening hardener is spread thereon to mix. Then, after the buried pipe 3 is located in the excavated hole 2 of a road 1, the fluidization treated soil 4 is poured into a hardener filling part in the hole 2 up to the position shown by a dotted line 5 to fill, and then, the quick hardening hardener 61 is spread thereon. The quick hardening hardener 61 to be spread and the fluidization treated soil 4 containing general hardener are mixed together by an ultrasonic wave oscillator so as to have specific thickness.
