Shaanxi Weinan Composite Drainage Board Company

Composite drainage board is a composite structure with drainage isolation function composed of one or two layers of non-woven geotextile and a layer of three-dimensional synthetic geonet core with different structures. They also have different isolation and reinforcement functions. According to different mesh core structures, their drainage and drainage capabilities vary in their application ranges. Although the permeability coefficient of geotextile is very large, it is an excellent water-permeable material. Water enters the three-dimensional geonet core through the geotextile and is quickly discharged through the channels provided by the mesh core. The channel sizes provided by different geonet core structures are and the magnitude of the force is proportional to their drainage capacity.
Composite geomembrane is composed of filament geotextile or short fiber geotextile, geomembrane and D geomembrane. Composite geomembrane has plane drainage and excellent anti-seepage properties. Composite geomembranes are divided into one cloth and one film and two cloths and one film. The width is - the weight is / square meter. The composite geomembrane has high physical and mechanical properties such as tensile strength, tear resistance and bursting. The composite geomembrane has high strength and good elongation performance. It has the characteristics of large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance and good anti-leakage performance. Composite geomembranes can meet the needs of civil engineering projects such as anti-seepage, isolation, reinforcement and anti-crack reinforcement in water conservancy, municipal administration, construction, transportation, subways, tunnels, and engineering construction. Composite geomembrane can be used in unconventional temperature environments due to its selection of polymer materials and the addition of anti-aging agents in the production process. It is often used for anti-seepage treatment of dams and drainage ditches and anti-fouling treatment of waste dumps.
Composite drainage net: The structure is a two-dimensional or three-dimensional geonet core compounded with needle-punched non-woven geotextile on both sides. The composite non-woven fabrics on both sides can prevent tiny particles from clogging the mesh core, allowing the mesh core to quickly drain out excess water that seeps out, and can drain capillary water under high loads. The vertical plastic ribs in the heavy mesh core structure have strong rigidity and also have Strong directional drainage function. It can act as isolation and foundation reinforcement. It is a new type of geosynthetic material with the function of drainage, filtering, isolation and reinforcement.
The company is located at the foot of Mount Tai, which is famous both at home and abroad and is the most famous among the five mountains. It mainly produces and operates various geosynthetic material products such as geogrids, geotextiles, three-dimensional cloth mats, reinforced fibers, and plastic grids, which are mainly used in domestic water conservancy, railways, highways, construction and other engineering fields.
The company is an enterprise integrating independent product research and development, production and equipment manufacturing. Our company's products have been widely used in national key projects such as Hewu Railway, National Highway Anhui Expressway, Beijing-Shanghai Highway Tianjin Section, Weiwu Expressway, Tianjin Luan to Tianjin and other national key projects. The performance indicators of the products are all Meets and exceeds national standards. Our company's leading foreign trade products, plastic networks and reinforced fibers, have been exported to Japan, New Zealand, Europe and the United States and other countries. The company is based on the domestic market and actively explores the international market to achieve diversified development in the market. The products have been unanimously recognized by engineering experts and domestic and foreign customers and have won a good reputation.
Our company always adheres to the business philosophy of people-oriented, realistic and innovative, and follows the path of survival by quality, development by innovation, and winning the trust of customers with high-quality products and services. We are willing to cooperate sincerely with customers at home and abroad to make progress together. Create a better tomorrow.
The three-dimensional geotechnical drainage net produced by the company is made of high-density polyethylene as the raw material, and the ribs are extruded through a special machine head. The three ribs are arranged at a certain distance and angle to form a three-dimensional space structure with drainage guide channels. The middle rib has greater rigidity and forms a rectangular drainage channel. This product can be used in landfills (including groundwater drainage layer leakage detection layer, leachate collection and drainage layer sealing, gas collection and drainage layer sealing, surface water collection and drainage), railway system drainage, highway subgrade and pavement drainage tunnels and barriers. Wall structure drainage.
Three-dimensional geotechnical drainage nets are available in high-strength and high-guidance types according to their uses.
Three-dimensional drainage net is made of high-density polyethylene (D) as raw material and anti-UV additives through a special extrusion molding process. It has a three-layer special structure with large rigid middle strips arranged vertically in the drainage direction to form a straight drainage channel. The ribs on both sides are arranged in a crosswise manner to increase the overall stability of the drainage network. Three-dimensional drainage network has the characteristics of anti-aging and corrosion resistance. Used in road and railway subgrades, it can effectively distribute loads, improve the bearing capacity and stability of the subgrade and extend its service life. Laying geonets on highway and railway slopes can prevent rock and soil from sliding, protect water and soil, and beautify the environment. The protective paving of reservoirs and river dams can effectively prevent landslides. In coastal engineering, it uses its characteristics of good flexibility and good permeability to buffer the impact energy of waves.
