Two-cloth-one-membrane composite membrane used in water conservancy projects
Product Introduction
Definition of two-cloth-one-film composite membrane
The two-cloth-one-film composite membrane is a geosynthetic material composed of two layers of non-woven fabric and one layer of high-density polyethylene (HDPE) film. This material combines the anti-seepage effect of geomembrane and the isolation, protection and drainage functions of geotextile, and is widely used in many fields.
Application fields
Water conservancy projects: such as anti-seepage treatment of reservoirs, canals, river embankments, lake dams, etc.
Industrial applications: anti-seepage of sugar factories, chemical plants, fertilizer plants, sewage treatment pools, etc.
Infrastructure construction: anti-seepage lining of tunnels, anti-seepage treatment of central green belts of highways, etc.
Structural characteristics and performance parameters of two-cloth-one-film composite membrane
Structural characteristics
The two-cloth-one-film composite membrane forms an effective waterproof barrier by sandwiching two layers of non-woven fabric between the HDPE film in the middle. This structural design not only improves the overall strength of the material, but also enhances its tensile and tear resistance.
Performance parameters
Unit area mass: According to different needs, the unit area mass range can range from 400g/m² to 1000g/m².
Membrane material thickness: The membrane thickness is generally between 0.1-1.5mm, and can be selected according to project requirements.
Physical and mechanical properties: including breaking strength, longitudinal and transverse CBR bursting strength, tearing strength, etc. These indicators ensure the durability and reliability of the material in actual use.
Construction methods and precautions
Construction methods
Surface preparation: Use sand or clay with a smaller diameter to level the surface.
Laying process: Do not stretch too tight during laying, and the parts buried in the soil at both ends are corrugated.
Protective layer setting: Use fine sand or clay to lay a 10cm transition layer on the laid two cloths and one membrane, and then lay 20~30cm blocks (or prefabricated concrete blocks) as an anti-impact protective layer.
Precautions
Joint treatment: Construction joint treatment is a key process, generally using overlap or hot welding to avoid leakage.
Material protection: During construction, stones should be avoided from hitting the material directly as much as possible. It is best to construct the protective layer while laying the membrane.
Advantages and application prospects of two-cloth-one-membrane composite membrane
Advantages
High durability: Due to the selection of polymer materials and the addition of anti-aging agents, the two-cloth-one-membrane composite membrane can be used in unconventional temperature environments.
Versatility: In addition to anti-seepage isolation, it also has the ability to filter drainage and reinforce protection.
Application prospects
With the improvement of infrastructure construction and environmental protection awareness, the demand for two-cloth-one-membrane composite membrane in water conservancy projects, industrial applications and infrastructure construction will continue to grow. Its excellent performance and wide application fields make it an important direction for the development of geosynthetics in the future.
In summary, as an important geosynthetics, the two-cloth-one-membrane composite membrane plays an important role in many fields with its excellent performance and wide application fields.
