초록

The high pressure jet grouting method is mainly used in the grouting. But, this method has problems that the scale and strength of improved body is not constant with ground condition. Considering these problems, triple rod MJM that results in the high-strength effect by the technology of the injected ${\phi}7mm$ cement mortar was developed. In this MJM, the unconfined strength is estimated with the various combination ratio and engineering characteristic, strength improvement effect of improved body, was checked through the field test. It is known that the application of MJM was verified with ground and construction condition.
