グシールド工法におけるコンクリートライニング
のプレス圧保持構造。 In the cast-in-place lining shield construction method, in which the concrete placed between the skin plate of the shield excavator and the formwork is pressed with a press ring at high pressure at the same time as the shield excavator excavates, the concrete contact surface of the press ring The sides are formed to protrude in an arc shape, and when pressure is applied by the press ring, a press pressure holding plate made of an elastic body with a width wider than the gap between the skin plate and the formwork is interposed between the press ring and the surface of the poured concrete. This pressurizes the concrete while elastically deforming the press pressure holding plate into an arc shape according to the shape of the press ring, and when the press ring is removed, both edges of the press pressure holding plate engage the skin plate and the formwork. A press pressure holding structure for a concrete lining in a cast-in-place lining shield method, characterized in that it is held in an arcuate curved shape by stopping.
