I do. An anchor tension member is inserted into the drill pipe from the drill pipe opening which is located at a position slightly inside the cylinder from the entrance on the ground side of the cylinder, and is inserted into the tip of the drill pipe. When the anchor tension member is pushed further in, the bit comes off and an opening is formed at the tip, and the injected grout and the soil and water in the ground flow back through the drill pipe with high pressure applied to the ground, so cylinder pressurization The cylinder made of the elastic body is strongly pressurized from the outside by means, and the cylinder is dented and deformed, and the opening of the drill pipe in the cylinder is sealed with the deformed cylinder. In this state, the swivel is lowered and placed immediately above the cylinder in a state where the outflow from the drill pipe is prevented. Then, pressurization by the cylinder pressurizing means is loosened to open the cylinder, and at the same time, the swivel is lowered and combined with the upper end of the drill pipe to make a secure connection. While pressing the grout from the swivel through the drill pipe into the ground, pull up the entire drill pipe by one step together with the swivel, and slightly join the seam between the uppermost drill pipe and the next-stage drill pipe from the inlet on the ground side of the cylinder into the cylinder. Adjust to the entered position. From this state, grout press-fitting is stopped once, and at the same time the uppermost drill pipe is cut off from the next and subsequent stages, and at the same time, the cylinder is pressurized and deformed by the cylinder pressurizing means to seal the upper end opening of the next stage drill pipe.
