As a multifunctional civil engineering material, woven geotextile not only plays an important role in infrastructure construction, but also demonstrates its unique advantages in ecological restoration projects. From land reclamation to river regulation, to silt solidification and highway pavement covering, woven geotextile has a wide range of applications and significant effects.1. Land reclamation: Stabilize the coastline and promote ecological balanceLand reclamation is one of the important means for many coastal cities to expand land resources. However, traditional land reclamation methods often cause serious damage to marine ecosystems, such as seawater pollution and loss of biological habitats. The use of woven geotextile can effectively reduce the occurrence of these problems.Enhance structural stability: woven geotextile has good tensile strength and durability, and can play a role in reinforcing embankments during land reclamation, preventing soil loss and slope collapse. By laying woven geotextile, the long-term stability of the newly built land can be ensured and the disturbance to the surrounding sea area can be reduced.Promote vegetation recovery: The surface of woven geotextile is rough, which is conducive to the attachment and growth of plant roots. After the land reclamation is completed, salt-tolerant plants can be planted on it to help fix the soil, increase the area of green space, and gradually restore the local ecological environment.Filtration and drainage function: woven geotextile can effectively filter fine particles in the water flow, while allowing water to pass freely to avoid water accumulation. This feature helps to maintain the humidity balance of the newly created land and provide suitable environmental conditions for plant growth.2. River regulation: protect river banks and improve water qualityRivers are an important part of the ecosystem, but with the development of cities and the intensification of human activities, many rivers are facing serious pollution and erosion problems. In this context, woven geotextile has become an indispensable material in river regulation projects.Flood prevention and disaster reduction: laying woven geotextile on both sides of the river bank can effectively prevent river bank collapse caused by flood scouring. It not only enhances the stability of the river bank, but also guides the water flow along the predetermined path to reduce the risk of flood disasters.Improve water quality: woven geotextile has good filtration performance, can intercept suspended matter and pollutants in the water, and purify the water quality. In addition, it can also serve as a carrier for microbial attachment and growth, promote the reproduction of beneficial microorganisms, and further improve the self-purification capacity of water bodies.Ecological slope protection: Using woven geotextile to build an ecological slope protection system can not only meet the needs of engineering protection, but also provide habitats for wild animals such as fish and birds. By planting local aquatic plants, a natural riverbank landscape can be formed to enhance the overall ecological value of the river.3. Deepwater port cofferdam: ensure construction safety and reduce environmental impactDeepwater port construction usually requires large-scale cofferdam operations at sea to create a relatively closed working area. In this process, woven geotextile plays an important role.Isolation and protection: woven geotextile can be used as the base layer of the cofferdam to isolate seawater from the construction area, prevent the spread of silt, and protect the construction environment. At the same time, it can also prevent external pollutants from entering the work area to ensure the quality of the project.Quick installation: woven geotextile is light and easy to carry, easy to transport and lay, which greatly shortens the cofferdam construction period and reduces construction costs. This is especially important for large-scale engineering projects with tight construction schedules.Eco-friendly design: After the cofferdam is removed, woven geotextile will not have a long-term impact on the marine environment because it is a degradable or easily recyclable material. This is in line with the environmental protection concept in modern engineering construction and helps to achieve sustainable development goals.4. Silt solidification: Improve land utilization and reduce secondary pollutionA large amount of silt is often accumulated near some industrial wastelands or sewage treatment plants. These silts not only occupy valuable land resources, but also may become a potential source of pollution. This problem can be effectively solved by adopting woven geotextile technology.Consolidation of silt: woven geotextile can wrap the silt by physical isolation to prevent it from further spreading. At the same time, combined with the use of chemical curing agents, the silt can gradually harden into a foundation material with a certain bearing capacity, thereby improving land utilization.Reduce the risk of leakage: During the silt solidification process, woven geotextile can effectively block the penetration of harmful substances into the surrounding environment and prevent groundwater from being polluted. This is of great significance for protecting groundwater resources.Greening transformation: The treated sludge site can be re-covered with soil and planted with vegetation, while woven geotextile continues to play its filtering and drainage functions, promotes vegetation growth, and ultimately achieves ecological restoration of the land.5. Highway pavement covering: Extend service life and reduce maintenance costsAlthough highway pavement covering seems to have little to do with ecological restoration, in fact, the rational use of woven geotextile can also indirectly promote ecological protection.Prevent crack expansion: Before laying asphalt, laying a layer of woven geotextile on the base can effectively prevent the development of reflective cracks and extend the service life of the road. This means that waste emissions caused by frequent maintenance are reduced, reducing pressure on the environment.Improve drainage performance: woven geotextile can quickly drain road surface water, keep the road surface dry, reduce the impact of water accumulation on vehicle driving, and also reduce the probability of road diseases caused by water accumulation.Reduce noise pollution: woven geotextile has a certain sound absorption function, which can reduce the noise generated by vehicle driving and improve the quality of life of residents along the line.In summary, woven geotextile has shown great application potential in many fields such as sea reclamation, river regulation, deep-water port cofferdam, silt solidification and highway pavement covering. It can not only improve the quality and safety of engineering projects, but also promote the restoration and protection of the ecological environment to a great extent. By making rational use of woven geotextile, we can better cope with the various environmental challenges we are facing and promote the development of society in a greener and more sustainable direction.
