ABSTRACT:
This invention concerns with a high pressure grouting process. For lateral cutting of earth in the ground, a high speed core water jet, having its injection velocity equal to at least a half of the sonic one and surrounded by an air ring jet is used. For solidifying the crushed earth, a cement milk is used which is poured separately and at a lower level than that of the air-water combined jet into the space in the ground which space has been formed by the action of the core water jet.
