The perforated corrugated pipe machine and equipment produced by Qingdao Cuishi machinery 

is a new corrugated seepage and drainage plastic pipe formed by adding other additives to 

high-density polyethylene (HDPE). 

The permeable corrugated pipe is processed by punching at the groove 

and wrapping needle punched geotextile around the pipe.

 According to the type of bellows, it can be divided into 

single wall permeable bellows and double wall permeable bellows. 

Because the pipe hole of the product is in the trough and in a long strip shape

, it effectively overcomes the disadvantage that the flat .

 It is widely used in drainage fields such as highway, railway subgrade, 

subway engineering, waste landfill, tunnel, green belt, playground and slope protection caused by high water content, as well as underground irrigation and drainage systems of agriculture and horticulture

. Together with flexible permeable pipe and plastic blind ditch

, it has become the three main products in China's civil engineering construction (water seepage and drainage).to be blocked and affect the drainage effect. 

It is widely used in drainage fields such as highway, railway subgrade, subway engineering, waste landfill, tunnel, green belt, playground and slope protection caused by high water content, as well as underground irrigation and drainage systems of agriculture and horticulture.
