The reinforced pipe is corrugated, so that the reinforced pipe has stronger bending capacity; the free state of the reinforcing pipe is spiral, and the spiral structure is the same as the spiral structure of the reinforcing pipe after being wound, so that the reinforcing pipe cannot generate bending stress after being wound in a spiral mode, namely the spiral reinforcing pipe does not have stress concentration after being wound in comparison with a straight reinforcing pipe, and the spiral reinforcing pipe cannot be separated due to stress concentration of a bonding part after being wound in a spiral mode; the free state of the reinforcing pipe is a spiral structure, the reinforcing pipe is also a spiral structure after being wound, and the spiral structures of the reinforcing pipe and the spiral structure are the same, so that the reinforcing pipe is also in a free state on the corrugated pipe and cannot be twisted.
Description
Technical Field
the utility model relates to a two high muscle winding are with ripple reinforced pipe.
Background
Traditional double-walled bellows, including inner wall and outer wall, the axial cross-section of outer wall is the corrugate, and the application of polyethylene double-walled bellows is very extensive, if be applied to many aspects such as farmland irrigation, city blow off pipe. In the polyethylene double-wall corrugated pipe in the current market, the wave crest part is a cavity, and the inside of the polyethylene double-wall corrugated pipe is not supported, so that the strength of the wave crest part is not greatly improved.
Therefore, designers design reinforcement in the wave crest, and various reinforcement structures are provided, so that corrugated pipes are mostly adopted as reinforcement for the convenience of bending and winding, and the corrugated pipes are existing pipe fittings and are processed according to the reinforced section shapes at most.
However, the conventional corrugated tube for winding is mostly linear, that is, the corrugated tube for winding is linear in a free state before winding. The corrugated pipe is convenient to bend, but the free state of the corrugated pipe is destroyed in the bending and winding process, bending stress can be gathered at the moment, the corrugated pipe with the winding structure is easily affected by the bending stress, and particularly in the spiral winding and splicing process, stress concentration occurs at the splicing part, so that the splicing part is separated. The straight corrugated pipe is spirally wound, if the straight corrugated pipe is used as a vertical reinforcement, the straight corrugated pipe cannot be completely vertical, the phenomenon of inclination is easy to occur, and the ring stiffness required by the design cannot be achieved at the moment.
Disclosure of Invention
The utility model provides a two high muscle winding are with ripple reinforced pipe, the outward appearance is the corrugate, and the appearance is the spiral during free state, does not have bending stress behind the spiral winding, avoids stress concentration, can not cause the pipe wall torsional phenomenon to appear in the spiral winding yet.
The utility model discloses a concrete technical scheme does: the utility model provides a two high muscle winding are with ripple reinforced pipe, the reinforced pipe is hollow structure, and the outward appearance is corrugate, and whole appearance is helical structure, and this helical structure is the same with its helical structure who twines on two high muscle winding pipes.
