The above-mentioned strength of the corrugated section is improved by arranging a reinforcement block in the corrugated section. The symmetrically distributed reinforcement ribs in the reinforcement block can make the corrugated section more evenly stressed and have a stronger pressure-bearing capacity, thereby improving the strength of the double-wall corrugated pipe. Even if the double-wall corrugated pipe is squeezed, it is not easy to deform and break, thereby extending the service life. Considering the existing high-strength HDPE double-wall corrugated pipe, the reinforcement block is completely fixed on the outer wall, so that the use strength of the outer wall is fixed, and the strength of the double-wall corrugated pipe remains unchanged during stretching, resulting in an inability to meet the use of a variety of complex environments.

[0026] Working principle:

[0027] Assembly stage

[0028] By passing the connecting piece 304 through the first connecting head 301 and manually rotating the connecting piece 304, the through groove 305 on the inner wall of the connecting piece 304 slides with the connecting block 302 until the rubber fiber block 303 on the connecting block 302 slides into the fixed position of the through groove 305, so that the connecting piece 304 is fixed to the first connecting head 301, and at the same time, the second connecting head 8 synchronously performs a similar working movement, so that the reinforcing block 401 at the lower end of the rubber connecting strip 402 slides into each double-wall corrugated pipe body 1, thereby achieving the effect of reinforcing the outer wall of the double-wall corrugated pipe body 1.

[0029] Working stage

[0030] Through the reinforcing wire 5 on the inner tube 2 of the inner wall of the double-wall corrugated pipe body 1, the reinforcing wire 5 can have a buffering effect during the stretching and bending of the double-wall corrugated pipe body 1, and the polyoxymethylene plastic of the corrosion-resistant layer 6 on the inner tube 2 isolates the internal flowing liquid to prevent the reinforcing wire 5 from being immersed in the inner tube 2 and corroding.
