Shandong geomembrane manufacturers - Shandong composite geomembrane price

Shandong geomembrane manufacturers [135-0548-0586] - Shandong geomembrane price supply throughout the reservoir seepage, water conservancy channel seepage, seepage lake, landfill seepage control. Learn the history and geomembrane applications, can provide valuable reference for geomembrane technology to a higher level. New synthetic geotextile geomembrane waterproofing deadening material rise eighties, following the soft PVC, chlorosulfonated polyethylene (CSPE) and butyl rubber polymer impermeable material, another new high-quality waterproof material. Geomembrane applications began in the mid-1980s, first Geomembrane in Canal Seepage areas, followed by the emergence of HDPE geomembrane. Older people water seepage engineering Henan Victory Channel, Shaanxi people lead Weiqu, Beijing and Shanxi Dongbeiwang several irrigation area irrigated with good results after use, it later extended to the reservoirs, sluices and reservoirs and other projects. Earlier impermeable membrane thickness is thin, since the production process is not advanced and scientific backwardness limits the thickness of the impermeable membrane, when people use the geomembrane 0.12mm-0.38mm. Thick geomembrane was in the early 1990s China began to apply. In 1992, Guangxi Liuzhou Tamura dam is currently being used by our highest geomembrane geomembrane rockfill dam, high 48m, has been used to date, its seepage better than expected even ideals. After 1998, the river closure of the Three Gorges Project is also used cofferdam impervious wall impermeable membrane. 1998 Fu Chau Han River Water Control Dike seepage control project uses 1.2 million square meters of impermeable membrane, including HDPE geomembrane, LDPE geomembrane, impermeable membrane and geomembrane. 21st century China, with the development of industry and science, China's production of impermeable membrane thickness of up to 3mm, width up to 8m, now a world leader. The current production bases in China impermeable membrane developed mainly in East China cities such as Beijing, Shanghai, Shandong and other cities. Now geomembrane has been widely applied to various seepage control project, such as: artificial lakes, golf courses, landfills, tailings disposal stations, tunnels, high-speed non-skid, aquaculture, gardens and petrochemical industries. Currently the National Geotechnical Institute continues to develop new synthetic materials use impermeable membrane. Several contacts geomembrane anchoring requirements geomembrane Specifications Thickness 0.2-2.0mm Width: 6000-4500mm. Landfill geomembrane geomembrane construction last several anchoring contact: 1) the anchoring groove: fixed HDPE geomembrane and geotextile protection layer, HDPE geomembrane and geotextile protection layer laying is completed, immediate use concrete panels suppress. 2) buffer platform: for HDPE geomembrane stability, prevent decline in the slope of the central additional buffer platform and the anchoring groove on the platform set up to alleviate the HDPE geomembrane under tension, increase stability. Buffer platform anchoring groove of the project because of the characteristics of the actual terrain, small and narrow, to pay special attention to the construction. 3) cut honggou: top anchor trench excavation cut honggou, diversion of foreign rain to prevent water directly into the landfill.
