Abstract
The utility model relates to a large-diameter corrugated pipe formed by a hole-ring-type zigzag-spring-pipe framework, effectively allowing not only an increase in the strength of large-diameter corrugated pipes, but also fundamental improvement in the elasticity of large-diameter corrugated pipes. The large-diameter corrugated pipe comprises an inner pipe. Multiple wedge nail holes are punched on a surface of a zigzag spring pipe, and edges of the wedge nail holes form a hole ring. The zigzag spring pipe is combined on an inner pipe, and the inner wall of the zigzag spring pipe is bonded and matched with the outer wall of the inner pipe. A plastic layer is arranged on the outer wall of the zigzag spring pipe. The large-diameter corrugated pipe has the advantages that the design of the hole-ring-type zigzag-spring-pipe framework not only greatly enhances the integral pressure resisting and bearing strength of the corrugated pipe, but also restrains, to the maximum extent, the change in the expansion and contraction quantity of the corrugated pipe due to temperature and further improves the adaptability of the corrugated pipe to different temperatures, thereby avoiding disconnection of and fluid leakage at a butt-joint part of the corrugated pipe.
