Product Description

Blind Pipes, also known as Plastic Blind Pipes or Drainage Blind Pipes/Drains, are a three-dimensional, porous material made by heating and melting thermoplastic synthetic resin, extruding it through nozzles to form fibrous strands, and then fusing the points of connection together. These are encased in geotextile as a filter membrane and come in various sizes. They have been in use internationally for over twenty years and are widely welcomed in the engineering community.

Performance Features

1. Blind pipe features high compressive strength, excellent pressure resistance, and good recovery. There is no issue of drainage failure due to overloading or other causes.

2. The surface perforations of the blind pipes are uniformly distributed and far exceed those of similar products, effectively collecting seepage water from the soil and promptly channeling it away.

3. Features include biodegradability in soil and water, resistance to aging and ultraviolet radiation, high temperature resistance, corrosion resistance, and retention of material properties over time.

4. The filter membranes for blind pipes can be selected according to different soil conditions, fully meeting engineering requirements and avoiding the缺点 of single, uneconomical filter membrane products.

5. On-site construction and installation of blind pipes are extremely convenient, reducing labor intensity and significantly speeding up construction efficiency.

6. High flexibility and strong adaptability to soil deformation, capable of avoiding accidents caused by failure of collection and drainage due to overloading, severe ground deformation, and uneven settlement.

7. Under the same drainage performance, the material, transportation, and construction costs of the blind pipes are lower than those of other types of blind grooves, resulting in a lower overall cost.
