Detailed Description
The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.
As shown in fig. 1 and 2: a seamless double-high-cavity reinforced drain pipe comprises a pipe body 1; the hollow high-cavity tube 2 is wound on the outer surface of the tube body 1 at equal intervals; an anti-impact hollow high-cavity protection tube band 3 is wound on the outer surface of the tube body 1 between the hollow high-cavity tubes which are wound equidistantly; the section of the hollow high-cavity protection tube band 3 is T-shaped. The two side surfaces of the widest part of the T-shaped section are respectively bonded with the outer side surfaces of the adjacent hollow high-cavity pipes 2 in a seamless mode, the possibility that broken objects fall into the pipe body in the construction process is eliminated, and the hidden danger of cracking and leakage of the pipe wall due to the impact of the compression of the pipe body is eliminated.
The hollow high-cavity tube body 2 is a trapezoid high-wave tube and has the beneficial effects of portability, easiness in processing and high ring stiffness.
The cross section of the hollow high-cavity tube 2 adopts a high-wave tube with a trapezoid structure. Compared with a common high-wave tube with a circular structure, the trapezoid-shaped structure has higher ring rigidity, more uniform stress on the tube body 1, dispersed stress, difficult cracking after extrusion and suitability for the drain tube with the double-high-cavity corrugated tube structure.
The hollow high-cavity tube 2 is wrapped with a protective layer to prevent the phenomenon of ring rigidity reduction caused by ring direction movement when the high-wave tube is pressed.
The hollow high-cavity pipe 2 and the hollow high-cavity protection pipe belt 3 are wrapped with a protective layer 4, and the protective layer is made of high-oxidation-resistant HDPE (high-density polyethylene) material, so that the influence on the service life of the pipe body caused by exposure of open sun in the use process of a construction site is avoided; meanwhile, the pipe body and the two seamless double-high-cavity pipes form an integrated structure, so that the ring stiffness of the whole pipeline is further improved.
The hollow high-cavity tube 2 and the hollow high-cavity protection tube band 3 are respectively spirally wound and adhered on the outer surface of the tube body 1, so that extra acting force can not be caused on the inner tube (tube body) and the outer tube (hollow high-cavity tube) in the winding process of the impact-resistant plate band (hollow high-cavity protection tube band).
Example 2:
see fig. 3. Unlike example 1, the following is: the section of the hollow high-cavity protection pipe belt is in an inverted T shape, and the widest part of the section of the hollow high-cavity protection pipe belt is directly adhered to the pipe body.
Example 3:
in this embodiment, on the basis of the first two examples, a lubrication layer is adhered to the inner wall of the pipe body 1. The lubricating layer is formed by hot melting and extrusion of a silicon core master batch and is used for reducing the friction coefficient of the inner wall, improving the sewage flow rate and avoiding the retention and accumulation of dirt and the damage of the pipe wall, so that the use safety is ensured after the drain pipe is buried underground, and the service life is prolonged.
Example 4:
in this embodiment, the pipe diameter formed by the hollow high-cavity protection pipe belt 3 wound on the pipe body 1 is smaller than the pipe diameter formed by the hollow high-cavity pipe 2. The corrugated pipeline with the structure has good clay property, is not easy to move, and is suitable for a drain pipe with a relatively small pipe diameter.
