For developing a simple and easy joint method of PCa-CFT, experiments were necessary to establish the grouting method, by which the gap at the joint can be filled properly. In this experiment, flowing conditions and void ratios are measured by the following variables. 1) Section size of steel tube, 2) Position of grouting injection inlet, 3) Position of the exhaust, 4) Interval of filling gap, and 5) The grouting pump form. As a result, The most suitable grouting method to restrain a void ratio of the gap in less than 2% was found.
