Composite drainage nets are materials commonly used in landfills, roadbeds, tunnel inner walls and other projects. So, what are the components of composite drainage nets?
The composite drainage net is composed of a three-dimensional plastic mesh core and a double-sided bonded permeable geotextile. This combination not only gives the composite drainage net a strong drainage capacity, but also makes it have the advantages of high tensile strength, corrosion resistance and long service life.
1. The plastic mesh core is the core component of the composite drainage net. It is made of high-density polyethylene (HDPE) and processed by a special extrusion molding process. This mesh core has a three-layer special structure. The middle ribs are rigid and arranged longitudinally to form a drainage channel; the ribs arranged crosswise up and down form a support to prevent the geotextile from being embedded in the drainage channel. Even under very high loads, the plastic mesh core can maintain a high drainage performance. The longitudinal and transverse tensile strength and compressive strength of the plastic mesh core are relatively high, which can ensure the stability and reliability of the composite drainage net during long-term use.
2. Permeable geotextile is another important component of composite drainage net. It generally uses materials such as polyester filament cloth, polyester staple fiber cloth or polypropylene staple fiber cloth. The main function of geotextile is to filter impurities, ensure smooth passage of the net core, and drain water in time. Geotextile can also be tightly bonded with the plastic net core to form an integrated drainage structure, which can improve the drainage performance and service life of the composite drainage net.
3. In addition to the above two main components, the composite drainage net can also be customized according to customer needs during the production process. For example, the geotextile composited on both sides can be filament cloth, short filament cloth, green cloth or black cloth. This flexibility allows the composite drainage net to better adapt to the needs of different projects and improve the overall performance and benefits of the project.
The composite drainage net can be used in many fields such as landfills, roadbeds, and tunnel inner walls. It can not only drain the accumulated water between the foundation and the subbase, block capillary water, but also improve the support capacity of the foundation and extend the service life of the road. Moreover, it has the advantages of convenient construction, shortened construction period and reduced costs.
As can be seen from the above, the composite drainage net is composed of two components: a three-dimensional plastic mesh core and a double-sided bonded permeable geotextile. Therefore, its drainage performance is very good and it can be used in major projects.
