Road Engineering
Pavement Reinforcement：During the road construction process, geotextiles are precisely laid at the junction between the subgrade and the pavement. It is like a diligent distributor of force, which can efficiently disperse the loads borne by the pavement evenly, greatly enhancing the bearing capacity of the subgrade. As a result, the probability of pavement deformation and crack generation due to uneven stress is significantly reduced. Take many newly built expressways as an example. The ingenious use of geotextiles has remarkably extended the service life of the roads and saved considerable costs for later maintenance.
Subgrade Drainage：Geotextiles have excellent water permeability and play an extremely important role as drainage channels in the subgrade structure. It can quickly drain the accumulated water in the subgrade, effectively preventing the subgrade from softening or even destabilizing due to excessive water accumulation. Especially in the complex environment of mountain road construction, geotextiles, with their excellent properties, successfully intercept and divert groundwater, providing a solid guarantee for the continuous dryness and stability of the subgrade.
Water Conservancy Engineering
Dam Seepage Prevention：In the dam construction project, geotextiles are often used as the core seepage prevention material. Laying it on the water-facing side of the dam or inside the dam body is like putting a tight waterproof armor on the dam, which can effectively block the seepage of water, greatly reduce the seepage loss of the dam, and significantly improve the overall seepage prevention ability of the dam. In some small reservoir dam reinforcement projects, the application of geotextiles has effectively solved the thorny problem of dam seepage.
Filtration Protection：For the drainage facilities in water conservancy projects, geotextiles, as high-quality filtration materials, play a vital role. On the one hand, it can prevent soil particles from being carried away by the water flow, and on the other hand, it ensures the normal penetration and flow of water. In the drainage parts of projects such as canals and sluices, geotextiles silently safeguard the unobstructed drainage system and effectively prevent the risk of structural damage caused by soil loss.
Environmental Protection Engineering
Landfill Sites：In the construction layout of landfill sites, geotextiles are applied to the liner system. It is like a solid isolation barrier, completely separating the garbage from the surrounding soil and successfully preventing the leachate from polluting the groundwater and soil. At the same time, geotextiles also have good drainage functions and can orderly guide the leachate to the collection system, creating convenient conditions for subsequent treatment work.
Sewage Treatment：In some process flows of sewage treatment plants, geotextiles can be used for the filtration and separation of impurities and suspended solids in sewage. For example, in the primary treatment stage of sewage, the filtration device made of geotextiles can accurately remove large-particle pollutants, thus significantly improving the overall efficiency of sewage treatment.
