Effective Drainage Geonet for Slope Protection in Hydraulic Engineering
Product Introduction
Three-dimensional composite drainage network is an advanced geosynthetic material. It consists of a three-dimensional plastic mesh with permeable geotechnical fabric adhered to both sides. It can replace traditional sand and gravel layers and is mainly used as a drainage material in landfills, roadbeds, and tunnel interiors. The following is a detailed introduction to its characteristics and applications.
Product Application
The application field of three-dimensional composite drainage network is very extensive, mainly including the following aspects:
Railway, Road, and Tunnel Projects: In these projects, three-dimensional composite drainage nets can effectively drain groundwater or surface seepage, enhance the load-bearing capacity of roadbeds or ballast, and prolong the service life of roads.
Landfill : The three-dimensional composite drainage network can not only drain water but also emit biogas produced by fermentation in the soil (especially waste), making it particularly suitable for use in landfills.
Hydraulic Engineering: In hydraulic engineering projects such as reservoirs and slope protection, three-dimensional composite drainage nets can reduce groundwater pressure, eliminate excess moisture, and protect the soil and buildings from damage caused by seepage deformation.
Municipal Engineering: In municipal projects such as urban roads and park greening, three-dimensional composite drainage networks can effectively drain water accumulation and improve the performance of ground use.
Product Property
The main characteristics of the three-dimensional composite drainage network include excellent drainage capacity, high tensile strength, and the ability to maintain stable drainage performance under high loads. In addition, the material also has good corrosion resistance and acid-base resistance, long service life, convenient construction, and low cost.
