The structural wall pipe is made of polyolefin by compression molding or thermal winding, and the general structure comprises a double-wall corrugated pipe and a winding structural wall pipe. The pipe is a novel acid-resistant, corrosion-resistant, compression-resistant and non-toxic green environment-friendly pipe, belongs to an environment-friendly and energy-saving high and new technology product, and is an ideal replacement product for pipes such as cement pipes, cast iron pipes, glass pipes and the like. How to make the structure wall tubular product have fine pliability and whole external pressure resistance ability, when having under overweight load road surface to use, guarantee that current safety is the factor that tubular product design was considered first. In application, the reliability of the project using the structural wall pipe under the same condition is improved compared with the traditional pipe, the comprehensive benefit is obvious, and the method has more superiority particularly in the construction site with narrow construction site, dense buildings, complex underground pipelines and busy road sections and in the acid-base soil laying process. Because the structural wall pipe has a plurality of excellent performances, the pipe can be widely applied to municipal drainage, building outdoor drainage, buried farmland water delivery and drainage, industrial pollution discharge, road drainage, sewage treatment plants, playground square engineering drainage, electric telecommunication engineering and the like.
The conventional structural wall pipe includes an inner plane outer corrugated double-wall corrugated pipe, a structural wall winding pipe B-type pipe (a structural wall pipe having an irregular outer shape), and a hollow structural wall winding pipe a-type pipe (a structural wall pipe having a smooth inner and outer surface) having an inner plane and an outer plane.
A high-density polyethylene (HDPE) double-wall corrugated pipe is a novel pipe with an outer wall with an annular corrugated structure and a smooth inner wall. High Density Polyethylene (HDPE) has excellent chemical stability, aging resistance, and environmental stress cracking resistance.

The outer wall of the double-wall corrugated pipe is of an annular corrugated structure, so that the annular rigidity of the pipe is greatly enhanced, the resistance of the pipe to soil load is enhanced, and the HDPE double-wall corrugated pipe has obvious advantages compared with other pipes in the aspect of performance. Under the condition of the same load, the HDPE double-wall corrugated pipe only needs a thinner pipe wall to meet the requirement. Therefore, compared with a solid-wall phase tube with the same material specification, the material can be saved by about half. The double-wall corrugated pipe has the advantages of light weight, less material consumption, high strength, high production efficiency, one-step formed socket joint and the like, and is a plastic pipe with the highest cost performance. However, the double-wall corrugated pipe has the defects that the outer wall of the pipe is easy to be ripped, broken and sunken due to dragging or impact during transportation and construction, the construction backfill abdomen is difficult to fill, and the like. The traditional hollow structure wall winding pipe A-shaped pipe with smooth inner and outer planes can overcome the defects of inconvenient transportation and construction, but the hollow structure wall winding pipe A-shaped pipe is heavy in weight and large in material consumption; moreover, as is well known, the production equipment efficiency of the hollow structure wall winding pipe A type pipe with the inner plane and the outer plane is low, the process controllability is poor, the cold welding mode of firstly extruding the square pipe for cooling and shaping and then extruding the melt adhesive for welding has stress and hidden danger of layering, no joint exists during production, other connection modes need to be adopted, the production period is long, the production process is complex, and a lot of unpredictable risks exist.
