1, Water conservancy engineering field
In the field of hydraulic engineering, geotextiles are mainly used for anti-seepage, protection, reinforcement, and improvement projects in rivers, lakes, reservoirs, and other areas. In these projects, the application of geotextiles can effectively prevent soil leakage and soil erosion, playing a role in protecting and enhancing the soil. At the same time, Shigongbu can also be applied to anti-seepage embankments in reservoirs, protection of water channels, and reinforcement of spillway channels.
2, Transportation engineering field
In the field of transportation engineering, geotextiles are mainly used for the reinforcement and improvement of roads such as highways, expressways, and railways. In these projects, the application of geotextiles can effectively enhance the bearing capacity and shear strength of the soil, improve the stability of gravel slopes and reinforced soil, and prevent soil erosion and low-temperature freezing damage. It can also be used as an isolation layer between the roadbed and the roadbed, or between the roadbed and soft soil roadbed, to improve the stability and bearing capacity of the roadbed, and to protect and extend the service life of the road.
3, Landscape engineering field
In the field of landscape engineering, geotextiles are mainly used in the construction and renovation of garden scenic spots such as parks, squares, sports fields, and leisure places. In these projects, the application of geotextiles can effectively prevent urban sandstorms and soil erosion, protect and strengthen the growth environment of vegetation roots, and play a role in beautifying the urban environment and enhancing urban ecology.
4, Environmental engineering field
In the field of environmental engineering, geotextiles are mainly used for anti-seepage and pollution prevention in landfill sites, solid-liquid separation and sludge drying in sewage treatment plants, and other engineering projects. In these projects, the application of geotextiles can effectively prevent the leakage and loss of sediment and pollutants, ensure the cleanliness and tidiness of the environment, and play a role in protecting and improving the ecological environment.
