GROUTING METHOD USING ELECTRIC CONDUCTING TRACER

摘要

PURPOSE: A grouting method using conductor powder is provided to rapidly and precisely confirm the grouting state of the ground through an electrical resistivity survey. CONSTITUTION: A grouting method using conductor powder is as follows. A liquid injection material(20) is mixed with conductor powder. The mixture is injected into the ground. The state of the injected injection material is confirmed through the electrical resistivity survey of the ground.
