Abstract:
To provide a novel use of an ion exchange resin and to reduce the amount of unnecessary excavated mud produced in boring a ground while restricting the cost of material such as a fluidizing agent.
A boring method includes a flowability applying process for adding a dispersant derived from ion exchange resin and a retardant to soil in an original position 3 forming a subgrade 2 to apply flowability to the soil.
