Geotechnical Composite Drainage Net Chemical Resistance 2m-6m Width Drainage of underground structures For garden and road

Product Overview
The three-dimensional composite drainage network is made of a unique three-dimensional geonet double-sided bonded geotextile.
It combines the reverse filtration function of geotextile and the drainage and protection function of geonet, providing a complete "reverse filtration-drainage function".Water-protective effect.The unique three-dimensional structure of the three-dimensional composite drainage net core can withstand theIt is subject to high compressive load and can maintain considerable thickness, providing good hydraulic conductivity.

Product Application
Geosynthetic composite drainage nets are widely used in various fields due to their excellent performance.
Road Construction: For the drainage of roadbeds and tunnel inner walls for highways, railways, etc., it can effectively improve the safety and service life of roads.
1. Municipal Engineering: Functions in urban drainage systems, such as reservoirs and slope protection projects in drainage engineering.
2. Landfill: As the bottom drainage layer of a landfill, it helps to discharge biogas and other harmful gases in a timely manner.
3. Hydraulic Engineering: Used in dams, reservoirs, and other hydraulic engineering projects to enhance stability.

Prouction

1.Material Preparation: High-density polyethylene (HDPE) or polypropylene (PP) for the core, and non-woven geotextile fabric for the outer layers. These materials are selected for their durability, strength, and drainage properties.

2.Extrusion and Forming: The HDPE or PP is melted and extruded through a die to form the core structure of the drainage net. This core is usually designed with a three-dimensional structure that provides high compressive strength and efficient water flow channels. The extruded core is then cooled and solidified.

3.Lamination: The geotextile fabric is laminated onto both sides of the core structure. This is done using heat and pressure to ensure a strong bond between the fabric and the core. The geotextile layers act as filters, preventing soil and other particles from clogging the drainage channels while allowing water to pass through.

4.Cutting and Rolling: The final product is cut to the required dimensions and rolled onto large spools for easy transportation and installation. Quality control checks are performed throughout the process to ensure the drainage net meets the specified standards for strength, permeability, and durability.
