Geocomposite Drain

1. Geocomposite Drain manufacture structure

Geocomposite Drain is a kind of new synthetics in our factory which is produced with advanced technology introduced from foreign countries. He is the thermoplastic synthetic resin melt extrusion nozzle through a fiber silk overlay together, and to connect the end points dissolved form three-dimensional porous materials.There is a layer of geotextile outside the geocomposite drain, whose main function is to sieve sand and clay so as to avoid blockage. This product has four shapes, including rectangular shape with many holes, rectangular shape with empty center, round shape with many holes, round shape with empty center. It also has all kinds of sizes and specifications which can meet different customers’different requirements.

2.Features

1） High pressure resistance strength

The geocomposite drain is made of many plastic fibers through fusion, which can’t be broken and damaged by pressure. Under 250kpa pressure, the interspace rate of the section can keep above 60%. Even though under greater pressure, there still be a spacing of 10-15% for drainage and its reversion ability is good.

2） High hole opening rate in surface

Good water collection and drain feature The hole opening rate in geocomposite drain’s surface is up to 90-95% which is above other similar products. It can effectively collect water in soil and drain the water off.

3）Permanent using life

The geocomposite drain is composed by sieve membrane made of fiber with good erosion resistance, and tri-dimensional reticulation made of polyethylene. These materials will not decompose in soil and water. We also add aging-resistance agent, so the material can keep its original characters.

4）The sieve membrane is selective

The sieve membrane can be selected pursuant to different soils and meet all kinds of requirements of project. So it can avoid old products using the same kind of sieve membrane.

5）Easy for construction

The geocomposite drain is light so it is easy for construction and the efficiency is good.

6） Good flexibility and adaptable to the earth distortion

Many overseas and domestic project examples in recent 20 years have well indicated that this product is reliable. This product is tested in China by Ministry of Communications, Ministry of Water Resources and Nanjing Water Science Academe of Industrial Ministry of Electric Power and its quality and property can be up to the national standard and some of its specifications is better than Japan’s, but the price is much lower than product made in Japan.

3.Engineering Applications

4) Drainage for slope of hill and bank .

5) Horizontal drainage for soft bed disposal.

6) Drainage for green field of sport field, golf course, airport, and park.

7) Drainage for coal piling field, garbage burying field, and fertilizer piling field.

8) As the drainage liner for pressure relief method.

9) As the underground drain system for faming and garden .

10) Drainage for roof garden.

11) As the sieve material for wasted water processing.
