Dress is more convenient.
Further preferably are as follows: the difference of the internal diameter of the internal diameter and tube body of the expansion mouth is equal to the pipe thickness of the tube body
Twice.
Through the above technical solutions, the difference of the internal diameter of the internal diameter and tube body of expansion mouth is equal to twice of tube body wall thickness, then phase
When being attached by expansion mouth, the inner surface of expansion mouth flushes adjacent two root canal bodies with the inner surface of tube body, to make ripple
Pipe will not hinder water flow when being used as Urban Underground pipe network, and water body flows more smooth in tube body.
Further preferably are as follows: the expansion mouth is equipped with internal screw thread, and tube body one end opposite with expansion mouth is equipped with and institute
State the external screw thread of screw-internal thread fit.
Through the above technical solutions, one end of the separate expansion mouth of upper root canal body and the expansion mouth of next root canal body pass through
The effect of being threadedly engaged is attached, and connection is stronger, and two root canal bodies are not readily separated, and globality is more preferable.
Further preferably are as follows: the external screw thread is equipped with sealing ring.
Through the above technical solutions, sealing ring is arranged on external screw thread, then expand when tube body is equipped with the insertion of externally threaded one end
When in oral area, sealing ring is abutted with the inner sidewall of expansion mouth, guarantees the leakproofness of adjacent two root canals body junction.
Further preferably are as follows: antioxidant coating is coated on the outer surface of the outer wall layer.
Through the above technical solutions, antioxidant coating can protect the bellows of PVC or HDPE material in the aerobic ring in underground
It is not easy to be oxidized in border, to improve the service life of tube body.
In conclusion the utility model has the following beneficial effects:
1. carbon fiber layer is arranged in inner wall layer, enhance tube body using carbon fiber layer high intensity, the characteristic of high microsteping modulus
Structural strength and tensile strength, so that tube body be allow to bear biggish pressure, the service life is longer；
2. external screw thread and expansion mouth is respectively set in the both ends of tube body, adjacent two root canals body passes through between external screw thread and expansion mouth
The effect that is threadedly engaged realize connection, it is easy to assembly and be connected firmly.
