る推進管用グラウト穴のシール装置。 A threadless grout hole is drilled at a predetermined position in the propulsion tube, and a small diameter cylindrical part that fits into the grout hole and a large diameter cylindrical part that engages with the periphery of the grout hole are provided at the inner and outer peripheries of the grout hole, respectively. A cylindrical member with The two large-diameter cylindrical parts that approach each other by screwing are fixed by clamping the peripheral edge of the grout hole, and a seal cap is attached to the internal thread formed on the inner peripheral surface of one of the cylindrical members or the other cylindrical member. The male thread is screwed together, and this seal cap has an outward flange portion, and when the male screw is screwed, the flange portion comes to engage with the large diameter cylindrical portion of the cylindrical member to be screwed. and an engagement portion between the flange portion of the seal cap and the large-diameter tube portion of the cylindrical member to be screwed together, and an engagement portion between the large-diameter tube portion of the cylindrical member and the inner peripheral edge of the grout hole. A sealing device for a grout hole for a propulsion tube, characterized in that a sealing member is provided between each section.
