GROUND IMPROVEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a ground improvement method capable of making press-fit of a fluid hardener without being required for any special large-sized mechanical equipment and forming a massive body by a non-fluid hardener in the ground. SOLUTION: Binary hardeners (L1 and L2) solidified by mixing two liquids with the hardener are used, the binary hardeners are separately conveyed to inject them into the ground (E) from an injection means (4), and the massive body (G) is formed by mixing the binary hardeners (L1 and L2) into the ground (E) by a mixing means (8) to solidify.
