Detail
The present invention relates to an expansion device and an S.C.I.G method (Soil Cement Injection Grouting Method) that can increase excavation efficiency by being installed in a soil cement injection equipment for improving soft ground.
In detail, the technology field of the expansion device of the soil cement injection equipment and the S.C.I.G method using the same is disclosed, which can shorten the construction period compared to the past, improve the constructability and construction economy, and reliably secure the verticality and constant diameter of the above-mentioned soil structure by moving along the leader of the soil cement injection equipment and simultaneously drilling the soft ground and discharging the injection material consisting mainly of soil, cement, and water to construct a continuous high-strength underground structure.
