LIQUEFACTION COUNTERMEASURE METHOD OF FOUNDATION BY MEANS OF SOLIDIFICATION USING AN INJECTION METHOD |
摘要 |
PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure method of foundation by means of solidification using an injection method capable of easily performing liquefaction countermeasure at a low cost while improving solidification of sand foundation.SOLUTION: The liquefaction countermeasure method solidifies the foundation by using an injection method. A filling pipe with the front end sealed is inserted into the foundation with a static manner or hitting manner. Subsequently, an injection material is dynamically injected with vibration amplitude larger limit infusion rate of the foundation to thereby positively generate cleavage veins in a sand foundation. Non-injected foundation between the cleavage veins is solidified by expanding the cleavage vein in orthogonal directions. |
