Example 1

As shown in fig. 1 and fig. 2, in the embodiment, a PP skeleton steel-plastic composite reinforced spiral drainage pipe is specifically provided, which aims to enhance the ring stiffness of the composite winding pipe and prolong the overall service life of the composite winding pipe by optimizing the structure of the composite winding pipe.

For the design of a composite wound pipe, the composite wound pipe comprises: a winding pipe and a corrugated pipe 4 integrally formed on the winding pipe to optimize the performance of the composite winding pipe.

For the basic design of the winding pipe, the steel belt 3 which is integrally formed and wound and arranged along the same spiral line with the winding pipe is arranged on the winding pipe, and the overall strength of the winding pipe is mainly enhanced under the action of the steel belt 3. The winding pipe is optimally designed as follows: the corrugated pipe 4 is added on the winding pipe, the corrugated pipe 4 is integrally formed on the winding pipe and is arranged between the spiral lines where the two adjacent steel strips 3 are located, namely the corrugated pipe 4 is also firstly wound along the spiral lines, and the winding path of the corrugated pipe 4 is embedded in the middle position of the spiral line where the steel strips 3 are located.

For the type of the corrugated tube 4, a PP corrugated tube or a carat corrugated tube is adopted as the corrugated tube 4, of course, these two types of corrugated tubes 4 are only preferred modes of the embodiment, and in practical application, the corrugated tube 4 made of other materials can be selected according to practical situations. On the other hand, in the present embodiment, the shape of the corrugated tube 4 is considered to be the cost of actual production and the ease of processing, and the corrugated tube 4 may have a circular, rectangular, or trapezoidal cross-sectional shape, and similarly, the corrugated tube 4 having a circular, rectangular, or trapezoidal cross-sectional shape is not unique, and the cut shape of the corrugated tube 4 may be changed according to the actual situation.

Based on the PP framework steel-plastic composite reinforced spiral drain pipe provided by the above, the processing technology is as follows:

set up a pipe wall, this pipe wall is established to double-colored double-deck panel, and two kinds of colours are decided according to specific selected materials, and the bilayer of pipe wall is ultrahigh molecular polyethylene layer 1 and PE layer 2 respectively, and uses ultrahigh molecular polyethylene layer 1 as the inner wall side of winding pipe, the advantage that uses ultrahigh molecular polyethylene layer 1 as the inner wall side lies in: the ultra-high molecular polyethylene layer 1 has good wear resistance and corrosion resistance, and can effectively prolong the service life of the winding pipe.

For the pipe wall, the steel belt 3 and the corrugated pipe 4 which are integrally formed with the pipe wall are arranged on the pipe wall, and in order to form the winding pipe, the pipe wall is wound along the same spiral line to form the winding pipe.

The corrugated pipe 4 and the steel strip 3 are coated with a PE layer 2, and after the winding pipe is formed, the corrugated pipe and the steel strip 3 are coated with a PE material layer. In order to further improve the integrity and the structural strength of the winding pipe, the heights of the outer coating layers of the corrugated pipe 4 and the steel belt 3 relative to the pipe wall are set to be the same, and after the mode design is adopted, the integral outer part of the winding pipe has good flatness.
