　　Smoking is prohibited on the construction site of the geomembrane. Shoes with iron nails or high heels with hard soles are not allowed to walk on the surface of the geomembrane, and all activities that may result in the production of geomembrane products are not allowed. The general characteristics of geomembranes include physical, mechanical, chemical, thermal, and durability functions Geomembranes have improved their waterproof (anti infiltration) function, deformation resistance, and durability in engineering applications Many engineering practices have proven that geomembranes have good impermeability; Has good elastic strain ability and can withstand different construction conditions and working stresses; Geomembranes with good aging resistance have particularly outstanding durability when placed underwater or in soil. On the other hand, protective measures should be taken in the project, such as minimizing the time that materials are exposed to sunlight, using rock and soil (with a thickness of at least 30cm) or deep water cover, etc. The general characteristics of geomembranes (impermeable membranes) include physical properties, mechanical properties, chemical properties, thermal properties, and durability properties. Waterproof geotextile is widely used in channel anti-seepage engineering. In recent years, the extensive application and effectiveness of geosynthetic materials in civil engineering, especially in flood control and emergency engineering, have attracted the attention of a large number of engineering and technical personnel. For the application technology of geosynthetic materials, normative technical requirements have been proposed in terms of anti-seepage, filtration, drainage, reinforcement, and protection, greatly accelerating the promotion and application of new materials. This material is widely used in the anti-seepage engineering of irrigation channels. Based on construction practice, this article briefly discusses the application technology of composite geomembranes. Waterproof geotextile is an impermeable material composed of geotextile and geotextile membrane. It is mainly used for anti-seepage. The composite geotextile membrane is divided into one fabric and one membrane and two fabrics and one membrane, with a width of four to six meters and a weight of; 200 to 1500 grams per square meter, with high physical and mechanical performance indicators such as tensile strength and resistance, suitable for civil engineering needs such as water conservancy, municipal engineering, construction, transportation, subway, etc. Due to the use of polymer materials and the addition of anti-aging agents in the production process, it can be used at unconventional temperatures.
