Claims

[Claims for Utility Model Registration] (1) A reinforcing structure for a hume pipe joint made of reinforced concrete, characterized in that a core ring is embedded in at least the outer circumference of the pipe. (2) A propulsion tube in which the reinforced concrete hume tube has an annular step at its leading male end, and its trailing female end has an embedded collar embedded in the outer periphery of the end and protruding from the end surface, 2. The reinforcing structure for a hume pipe joint according to claim 1, wherein the core ring is disposed on the annular stepped portion so as to cover at least the outer circumferential surface of the distal end thereof. (3) The core ring is an annular body having a band-shaped cross section that covers the entire outer circumferential surface of the annular step, or an annular body having an L-shaped cross section that covers the entire outer circumferential surface and the entire tip surface of the annular step, or the annular step. 3. The reinforcing structure for a hume pipe joint according to claim 1, wherein the reinforcing structure is an annular body having a U-shaped cross section and covering the entire outer circumferential surface, the entire distal end surface, and the inner circumferential surface of the section.
