GROUND SOLIDIFICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for solidifying the ground in a short time even in winter even if there is a puddle in the ground and even if there is meandering, and for stabilizing the ground by spraying solidification material slurry in a constant thickness.SOLUTION: A ground solidification method is provided so that a solidification material of including a coagulation conditioner of 0-1 pt.mass to a solidification material of 100 pts.mass of including cement and/or blast furnace slag powder of 100 pts.mass and amorphous calcium aluminate powder of 10-50 pts.mass of the CaO/AlOmolar ratio of 1.7-3.0, is pneumatically force-fed by compressed air, and water of 70-300 pts.mass is continuously supplied to the solidification material of 100 pts.mass on the tip of a solidification material supply pipe, and solidification material slurry is prepared, and the prepared solidification slurry is sprayed on a farmland surface from a discharge pipe hose, and the ground is solidified.
