Rapidjet工法

The Rapidjet method is a method of jet grouting that applies a double-tube grouting system with two nozzles on opposite sides of the jetting spray nozzle device (Monitor) with drilling bit mounted at the bottom of the inner tube. It uses high-pressured jet grout slurry to erode and mix the in-situ soil to form soil-cement mixture columns. It can carry out efficient grouting to form large-diameter columns of up to 4~5 m at a high speed.
