Drainage pipe series double-wall corrugated pipe
In addition to the characteristics of ordinary plastic pipes such as good corrosion resistance, high insulation, smooth inner wall, and low flow resistance, double-wall corrugated pipes also use The special hollow ring structure has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, and is not easy to be damaged. At present, it has been widely used in many fields in developed countries, especially in the United States, Canada, Japan and many European countries. Double-wall corrugated pipes are widely used in municipal drainage and sewage, agricultural irrigation, coal mine ventilation, chemical industry, communication cable sheathing and other fields. Practice has proven that while meeting the strength and stiffness requirements of engineering applications, the use of double-wall corrugated structures can save materials. In addition, compared with concrete pipes and cast iron pipes, it is easier to transport and install, reducing the labor intensity of construction personnel and reducing the total investment of the project. With other advantages, it is an ideal replacement product for concrete pipes and cast iron pipes.

Performance of structural wall drain pipes
The advantage of structural wall drain pipes is that they are easy and fast to construct. Since the pipe has good flexibility on a macro scale, it serves as a load-bearing structure for the interaction between the pipeline and the backfill soil, and it has strong rigidity in local pipe sections. Therefore, there is no need to set up a concrete cushion or concrete pipe during pipeline construction. The foundation can be laid directly in the trench. It can basically be excavated, piped and backfilled at the same time, which saves the construction period, simplifies the construction procedures, saves manpower and material resources, and has significant economic and social benefits.
