ール構造。 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 under high pressure at the same time as the shield excavator excavates, the skin plate is placed at the tip of the concrete pouring. A sealing material is installed on the inner periphery of the skin plate, and as the skin plate moves forward, the sealing material moves relatively backward together with the pressed concrete, and pressure is applied between the inner periphery of the rear end of the skin plate and the concrete lining. A lining seal structure in a cast-in-place lining shield construction method, characterized in that the lining is retained.
