Salt drainage tube: also known as plastic pipe filter, soft filter pipe vacuum tube pre-filter press soft perforated corrugated pipe, exhaust pipe base, drainage is to add high-density polyethylene (HDPE) and the formation of other additives. new exterior corrugated plastic pipe seepage drainage, flooding bellows is processed through the recess punch, tube surrounded by outsourcing acupuncture geotextile. Bellows can be divided according to the type of single-wall and double wall corrugated pipe permeable permeable bellows. As the product of the hole in the trough and is a long strip, effectively overcome the hole flat products easily clogged drainage effect and impact of the drawbacks, for different drainage requirements, pore size can be *0mm***0mm, and **0 degrees can be evenly distributed within the range of **0 degrees, **0 degrees, *0 degrees, etc., it is the soft water pipe, plastic blind ditch has become China Civil Engineering Construction (seepage and drainage) in the three major products.
