Geotextile, as a new type of building material, has a wide range of applications in many fields and plays an important role.
In hydraulic engineering, geotextiles are commonly used for the protection and reinforcement of dams, riverbanks, channels, and other structures. It can prevent soil particles from being washed away by water flow, playing a dual role in filtration and drainage. For example, in riverbank protection projects, laying geotextiles can prevent soil from entering the river channel, while allowing water to freely seep out, maintaining soil stability, effectively extending the service life of the riverbank, reducing maintenance costs, and ensuring the normal operation of water conservancy facilities.
In the field of road engineering, the application of geotextiles is also crucial. Laying geotextile between the base and sub base of newly constructed roads can enhance the overall integrity of the road structure and prevent pavement cracking caused by uneven settlement of base materials. In the restoration project of the old road, geotextile can be covered on the old road surface to isolate, reinforce and waterproof, delay the development of road diseases, improve the bearing capacity of the road, reduce the number of road repairs, lower the risk of traffic interruption, improve the efficiency and safety of road traffic, and provide strong support for transportation.
Geotextile is also indispensable in railway engineering construction. Laying geotextile on railway subgrade can effectively disperse train loads, prevent lateral displacement and upward extrusion of subgrade soil particles, and enhance the stability of the subgrade. At the same time, it can also prevent groundwater from rising and eroding the roadbed, ensuring the smoothness and stability of railway tracks, reducing track deformation and maintenance workload, and ensuring the high-speed and safe operation of trains.
In terms of environmental engineering, geotextiles can be used as liners and covers for landfills. As a cushion, it can prevent garbage leachate from polluting groundwater, protect soil and water resources; As a covering material, geotextile can reduce rainwater entering landfills, decrease the amount of leachate generated, and suppress odor emission and garbage flying, which is beneficial for the protection of the surrounding environment and the maintenance of ecological balance.
Geotextiles play an indispensable role in many industries such as water conservancy, transportation, and environmental protection due to their excellent characteristics of filtration, drainage, isolation, and reinforcement. They provide important guarantees for the stable operation, durability, and environmental protection of various engineering projects, promoting the development of infrastructure construction and environmental protection. With the continuous progress of technology, their application prospects will be even broader.
