RJP (Rodin Jet Pile) Jet Grouting Technology
A variation of the conventional triple-fluid system, called RJP technology, was introduced by Tsujita (1996). In RJP technology, both the water and grout jets are simultaneously injected under high pressures, such that the soil is subjected to two stages of erosion, initially by the water jet, then followed by secondary erosion by the grout jet. The exposure of the soil twice to the cutting action of the jets enables a larger column to be formed.
