Claims

[Scope of Claim for Utility Model Registration] A pipe body having a tubular concrete layer, and an inner layer and an outer layer made of plastic that respectively cover the inner peripheral surface and outer peripheral surface of the concrete layer except for the ends; A pipe end structure of a propulsion pipe, which has a continuous concrete layer and an inner layer, and an insertion part in which the outer diameter of the concrete layer is smaller than the concrete layer of the pipe main body. , Tension that is continuously and tightly covered from the outer circumferential surface of the tip of the concrete layer at the end of the pipe main body, where the outer layer is not coated, to the outer circumferential surface of the concrete layer at the proximal end of the insertion part. A reinforcing ring with excellent strength closely covers the concrete layer where the outer layer of the pipe main body is not covered and the reinforcing ring fitted to the concrete layer, and also covers the concrete layer at the insertion part 14 and the concrete layer. A tube end structure of a propulsion tube, comprising: a coating layer that tightly covers a reinforcing ring fitted to the tube;
