Abstract

See full text

An underground steel-concrete structure pipeline with a spiral composite reinforcement ring on an inner wall and a manufacturing method thereof. The pipeline includes a pipe body, multiple rows of concrete overflow holes spirally arranged on a pipe wall of the pipe body, a reinforcement ring capable of wrapping the concrete overflow holes, and concrete is filled in a hollow cavity between the reinforcement ring and the pipe wall to form a spiral concrete flow passage. The advantages are that the overall annular strength of the pipeline is reinforced by the reinforcement ring; the concrete filled between the reinforcement ring and the inner wall of the pipe body improves the compressive strength of the pipe body; the concrete overflowing from the overflow holes on the pipe wall combines the pipe body with a pit; and the pipeline solves the difficulty of using large-size steel structure products in underground common pipeline projects.
