Geonets, a mesh-like material made from polymers, are widely used in drainage systems due to their excellent permeability and tensile strength. Their primary function is to facilitate the removal of excess water and prevent water pressure buildup, thereby protecting the stability of engineering structures.
In drainage systems, geonets are commonly used as drainage layers. For instance, in underground engineering, geonets can be installed at the bottom or sides of underground structures to form effective drainage channels, preventing groundwater infiltration and accumulation, and avoiding structural damage. Additionally, in road and railway construction, geonets can be used for subgrade drainage to prevent water retention, which may lead to subgrade softening or settlement.
The advantages of geonets lie in their high permeability and durability. They can quickly drain water while resisting chemical corrosion and physical wear, ensuring long-term stable drainage performance. Moreover, geonets are easy to install, improving construction efficiency and significantly reducing project costs.
In summary, the application of geonets in drainage systems not only enhances drainage efficiency but also improves the stability and durability of structures, making them an indispensable material in modern engineering construction.
