Presently it becomes deeper underground excavation with rapid growth of industrial and gravitation of the population. By purpose of cut-off, impervious, and ground strengthening etc., grouting is used. But it is difficult to check impregnation effect because grouting operate in under ground. Up to this day, many methods of inspection have been designed, but these methods is not trusted.
Therefore, the purpose of this study is to confirm to ground improvement effect by using temperature measurement.
From the result, the more sensor adjoin impregnation tube, the more temperature increases.
