Geotechnical materials refer to various materials used in civil engineering to improve soil properties, enhance structural stability, isolate, drain, and prevent seepage. They are usually made of synthetic fibers, polymers, and other materials, and are widely used in infrastructure construction such as roads, railways, water conservancy, environmental protection, and landfills.
The service life of geotechnical materials usually depends on the type, quality, construction method, and application environment of the material. Generally speaking: The service life of geotextiles varies from 10 to 30 years, and if exposed to strong ultraviolet radiation and harsh weather conditions, the service life will be relatively short. The service life of geomembrane is relatively long, generally up to 20-50 years, especially HDPE geomembrane, which has a relatively long anti-aging ability in a good environment. The service life of geogrids and geonets is usually between 20-30 years, depending on the corrosiveness of the application environment.
When selecting geotechnical materials, the following factors need to be considered: Project requirements: such as whether anti-seepage, reinforcement, filtration, or drainage functions are needed. Soil and environmental conditions: such as soil type, humidity, temperature, chemical corrosiveness, etc. Design parameters: such as strength, permeability, aging resistance, etc. Construction conditions: including laying thickness, construction method, etc. After understanding the specific application scenarios, the most suitable material type can be determined through communication with material suppliers or professional engineers.
Geotextiles: Used for functions such as separation, reinforcement, filtration, and drainage. Geomembranes: Used for anti-seepage, commonly used in anti-seepage projects such as landfills and reservoirs. Geogrids: used to reinforce soil, enhance the stability of roadbeds and foundations. Geonets: mainly used for drainage and soil reinforcement. Geobags: commonly used for river management and slope protection. Geosomposites: composed of multiple layers of geosynthetic materials with different functions, possessing multiple functionalities, such as composite geomembranes.
Roads and railways: Used to reinforce soil, improve roadbed stability, and prevent settlement, commonly used materials include geotextiles and geogrids. Water conservancy engineering: used for anti-seepage, drainage, reinforcement of dams, river treatment, etc. Common materials include geomembranes, geotextiles, geogrids, etc. Landfill site: used for anti-seepage and isolation to prevent leachate from polluting groundwater. Commonly used materials are geomembranes and geotextiles. Mining engineering: used for foundation reinforcement and anti-seepage, to prevent water infiltration or pollution in mines, commonly using geomembranes and geotextiles. Ecological restoration and landscape construction: used to prevent soil erosion, stabilize soil, and promote vegetation growth, commonly using geotextiles, geonets, etc.
What are the construction precautions for geotechnical materials? Avoid damage: During the construction process, geotechnical materials should be protected from mechanical damage or excessive stretching. Material laying: Ensure even and wrinkle free laying, avoid incomplete or uneven coverage. Seam treatment: Use appropriate welding or bonding methods where seams are needed to ensure good sealing of the seams. UV protection: If the material is exposed to sunlight for a long time, it may degrade due to UV radiation. Measures need to be taken to protect the materials, such as using coverings or adding anti UV agents.
