Description :

　　Dezhou Zhengyu Geotechnical Materials Co., Ltd. composite geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, the plastic films used for anti-seepage applications mainly include polyvinyl chloride (PVC) and polyethylene (PE), which are high molecular weight chemical flexible materials with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. The thickness of the membrane is generally 0.30-2.00mm. The main mechanism is to use the impermeability of plastic film to block the leakage channel of the earth dam, and to withstand water pressure and adapt to dam deformation with its high tensile strength and elongation. Non woven fabric is also a type of polymer fiber chemical material, which is formed by needle punching or thermal bonding, and has high tensile strength and extensibility. At present, the non-woven fabrics mainly used in composite include: polyester short fiber needle punched geotextile, polyester long fiber spun clay geotextile, flat fiber plastic woven fabric, etc. After being combined with plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of the non-woven fabric, which is beneficial for the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemical reactions, and are not afraid of acid, alkali, or salt erosion.

　　Specification for Composite Geomembrane:

　　Performance characteristics of composite geomembrane:

　　Good flexibility, in addition to the anti-aging, high strength, good flexibility, and isolation properties of geotextiles, it also has a sealing (anti-seepage) function.

　　Application and Function of Composite Geomembrane:

　　Widely used in many fields such as water conservancy, dams, tunnels, road construction, airports, etc., it mainly plays a role in waterproofing, anti-seepage, protection, reinforcement, leakage prevention, isolation, etc. in engineering.

　　Precautions for Construction of Composite Geomembrane:

　　1. The use should be buried, and the covering thickness should not be less than 30cm

　　2. The entire anti-seepage system is composed of a cushion layer, anti-seepage layer, transition layer, and protective layer. Production and wholesale of 800g composite waterproof geotextile, 150g/0.5mm/150g with two fabrics and one membrane, Shandong

　　3. The soil should be solid, avoiding uneven settlement, cracks, and removing grass and tree roots within the anti-seepage range. Lay a protective layer of sand or clay with small particle size on the contact surface with the membrane.

　　4. When laying, do not pull the geomembrane too tightly. It is better to embed the soil at both ends in a corrugated shape, especially when anchoring with rigid materials, leaving a certain amount of expansion and contraction.

　　5. During construction, stones and heavy objects should be avoided from directly hitting the geomembrane. The construction should be carried out while laying the membrane and covering the protective layer.

　　Laying method of anti-seepage geotextile:

　　1. Waterproof geotextile materials have a large self weight and should be transported and laid using a scraper.

　　2. The joint of waterproof geotextile must be parallel to the longitudinal line of the stack yard.

　　3. Damage and repair must meet the following technical requirements:

　　The patch material used to repair holes or cracks must be consistent with the material of the anti-seepage geotextile.

　　The patch should extend at least 30 centimeters beyond the range of the damaged anti-seepage geotextile. Production and wholesale of 800g composite waterproof geotextile, 150g/0.5mm/150g with two fabrics and one membrane, Shandong

　　After the installation of anti-seepage geotextile, the construction surface should be inspected and any objects that may puncture the anti-seepage geotextile should be cleaned up.

　　5. All exposed edges of the anti-seepage geotextile must be immediately compacted with sandbags or other heavy objects to prevent the geotextile from being blown by the wind or pulled out of the surrounding anchoring ditch. The anti-seepage geotextile should not be unfolded in windy weather conditions to prevent it from being blown up by the wind.

　　6. The laying method of anti-seepage geotextile must ensure direct contact with the underlying base layer and eliminate wrinkles. Any wrinkles, folds, or arching may cause the same situation to occur in other geotechnical materials in the soil layer. To avoid wrinkles, folds, and arching, we will eliminate these problems by re laying, cutting, and repairing the anti-seepage geotextile according to the technical specifications.

　　7. The equipment for anti-seepage geotextile must be approved by the supervising engineer before use, and unprotected razors or "quick knives" are not allowed.

　　8. When laying anti-seepage geotextile, try to minimize the dragging of the anti-seepage geotextile on the foundation to avoid damage to the contact surface between the anti-seepage geotextile and the ground.
