Hebei Cangzhou anti-seepage geotextile has good anti-seepage effect

Anti-seepage geotextile is also called composite geomembrane. Composite geomembrane is a geotextile anti-seepage material composed of plastic film as the anti-seepage base material 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 at home and abroad mainly include polyvinyl chloride and polyethylene. They are polymer chemical flexible materials with small specific gravity, strong extensibility and high adaptability to deformation. Corrosion resistance, low temperature resistance and frost resistance. Its main mechanism is to use the impermeability of the plastic film to block the leakage channel of the earth dam. Its greater tensile strength and elongation can withstand water pressure and adapt to the deformation of the dam body. Non-woven fabric is also a kind of polymer short fiber chemical material. Needle punching or hot bonding has high tensile strength and extensibility. When combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction of the contact surface due to the rough surface of the non-woven fabric. The coefficient is beneficial to the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemicals and are not afraid of acid, alkali, and salt corrosion.
The service life of the composite geomembrane is mainly determined by whether the plastic film loses its anti-seepage and water-proofing effect. According to the Soviet national standards, the thickness of the polyethylene film with stabilizer for hydraulic engineering is . The service life is up to ~ years. The working life under sewage conditions is ~ years. Therefore, the service life of the composite geomembrane is sufficient to meet the service life of the dam's anti-seepage requirements.
Performance of geotextile
Geotextile is a new type of building material. The raw material is synthetic fiber made of polyester, acrylic, nylon and other high molecular polymers. According to the manufacturing method, it is divided into two types: woven geotextile and non-woven geotextile.
Textile geotextile is a geotextile with interwoven warp and weft (warp-knitted geotextile). Its thickness is thinner and its general thickness is... Its tensile strength is relatively strong, its permeability coefficient is relatively high, and its texture is stable and durable.
Non-woven geotextile is a mesh made of irregularly arranged fibers that are bonded and needled. Commonly used is needle-punched non-woven geotextile. This type of geotextile has stronger compressibility, larger porosity, and better water conductivity than woven geotextiles.
Geotextile has many functions such as anti-seepage, reverse filtration, drainage, isolation, reinforcement, protection, sealing, etc. Compared with the anti-seepage effect of conventional masonry and concrete materials, geotextile has low investment, simple construction technology, short construction period and anti-seepage effect. It has the advantages of good results and high effective channel utilization coefficient. For example, in the construction of the Weihe River embankment project in Xianyang City, geotextiles and traditional methods were used for construction of two sections of river embankments. After comparing the two construction plans, the river embankment built using geotextile has a total investment of 10,000 yuan and 10,000 man-days. However, using the traditional plan to build a river embankment of the same length requires an investment of 10,000 yuan and 10,000 man-days. Compared with the two plans, the investment and labor can be reduced by % and % respectively by using new geotextile materials. This new material was successfully used in the water-saving renovation of the East Fourth Branch Canal and the North Main Canal rescue project in the Baojixia Irrigation District. It not only achieved obvious anti-seepage effects, but also reduced investment and shortened the construction period. It can be said that it kills multiple birds with one stone.
Geotextiles are textile materials that have been widely used in civil engineering in recent years. Geotextiles have excellent functions of isolation, filtration, drainage, reinforcement, protection, and sealing. Geotextiles are widely used in the construction of highways, railway subgrades, airport runways, river beds, dams, sea reclamation, flood control and rescue and other major projects. Geotextile product specifications:-. Geotextile performance characteristics: good flexibility, good water permeability, filtration, isolation performance, convenient construction, etc. Geotextiles are used for filtering, isolation, drainage and maintenance of roads, railways, dams, reclamation and other projects. Geotextile packaging specifications: width - length - (according to customer requirements) composite geomembrane (referred to as geomembrane), also called anti-seepage geotextile, usually refers to geotextile (woven fabric or plastic woven fabric) and membrane bonded together of synthetic materials. One cloth and one membrane refers to a layer of geotextile adhered to a layer of membrane. Two cloths and one membrane refers to a membrane sandwiched between two layers of geotextile. Two membranes and one cloth refers to a geotextile sandwiched between two membranes. Composite geomembranes have many advantages. For example: woven geotextile composites can reinforce the geomembrane and protect the membrane from external forces during transportation or construction. Nonwoven geotextile composites not only provide reinforcement and protection for the membrane, but also provide drainage. The exhaust function simultaneously increases the friction coefficient of the membrane surface and is widely used in water conservancy projects and traffic tunnel projects.

Geomembrane has excellent anti-seepage, anti-corrosion properties, good chemical stability, and can be processed according to actual engineering needs. It has been widely used in the anti-seepage of embankments, dams, and reservoirs in water conservancy projects. It is used as anti-seepage, anti-corrosion, leak-proof and moisture-proof materials in channels, reservoirs, sewage pools, swimming pools, house construction, underground buildings, garbage dumps, environmental engineering, etc. Developed countries have begun to widely use this technology since the 1990s. Our country has also gradually used geomembranes for anti-seepage geotextiles in various projects since the 1990s. Concrete (cement concrete, asphalt concrete) cracking is an old problem. Adding synthetic fibers (engineering fibers) to concrete is one of the most effective measures proven in practice. Engineering fibers include polypropylene fiber, polyester fiber, polyacrylonitrile fiber, etc. Polypropylene fiber, polyacrylonitrile fiber and polyester fiber can all be used in cement concrete.
