Zusammenfassung: | The underground reinforced concrete structure pipeline comprises a pipe body, the spiral reinforcing ring is arranged on the inner wall of the pipe body, the outer side face of the reinforcing ring is fixedly connected with the inner wall of the pipe body, a spiral cavity is defined between the reinforcing ring and the inner wall of the pipe body, and the reinforcing ring is arranged in the cavity. A plurality of overflow holes are formed in the positions, corresponding to the cavities, of the pipe wall of the pipe body. The cavity is filled with concrete; the concrete is prepared from the following components in parts by weight: 70 to 200 parts of cement, 2 to 8 parts of self-repairing agent, 90 to 260 parts of stone, 0.6 to 3 parts of composite fiber, 80 to 120 parts of mineral powder, 400 to 650 parts of sand, 10 to 60 parts of fly ash, 0.5 to 2 parts of water reducing agent component, 0.5 to 3 parts of expanding agent, 0.1 to 1 part of cement-based capillary crystalline material and 60 to 150 parts of mix |
