Abstract: PURPOSE: An underground grouting method using vacuum drainage for control of grout flow direction is provided to minimize fracturing grouting or the loss of a grout material caused by the subsurface water flow. CONSTITUTION: An underground grouting method using vacuum drainage for control of grout flow direction is as follows. An injection hole(10) and a vacuum drain hole(20) are punched underground at a certain interval. A grout material is pressure-injected in the injection hole so as to guide the grout material toward the vacuum drain hole and, at the same time, a vacuum is made in the vacuum drain hole. The grout material is pulled into the vacuum drain hole and a bulb(30) is formed between the injection hole and the vacuum drain hole. The grout material is pressure-injected in the vacuum drain hole so a structure by the grout material is formed underground.
