Plastic Blind Ditch Extruder

Plastic blind drains are underground engineering facilities used for 

immersion treatment of pollutants and lowering the groundwater level. 

They are made of materials such as polypropylene (PP) and are usually 

located underground. They consist of a series of interconnected pipes, 

Wells and sieve holes.

Plastic blind ditches are in the form of a three-dimensional network, 

with various structural forms such as rectangular, hollow matrix, and 

hollow circular. Their void ratio is 80-95%, making them suitable for 

both spatial composition and management, and they are lightweight. 

Their compressive strength is more than ten times that of tubular resin 

structures, so there is no need to worry about them being damaged by 

soil pressure.
