EXCAVATED SOIL RECYCLING METHOD IN SHIELD TUNNELING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an excavated soil recycling method in shield tunneling method making it possible to transfer the soil to a required distance by selecting a plasticizing grout enabling a long distance pressure feed. SOLUTION: The invention is a recycling method of excavated soil recycled in an execution site as a civil engineering material for a shield tunneling method. Muddy water made of excavated soil and water, a curing liquid made of a cement-based solidifier and water, a plasticizing liquid made of a plasticizer and water are mixed together in an application site in a shield tunnel for back filling.
