Edison Group is the country's largest R & D base of geosynthetics, "Product innovation, leading the market," but also "Edison" Over the years adhere to a habitual attitude. Group will invest more than 600 million per year for new product development, to come up with a net profit of 10% per year, reward management reform and innovation aspects of the production, stimulate business and technical personnel and employee enthusiasm for innovation. Mature technology team is "Edison" Innovation guarantee. Currently, the provincial geosynthetics Quality Supervision and Inspection Center located in the "Edison", the existing full-time research and development staff of 68 people. "Edison" also with the Shandong Agricultural University, Shanghai Donghua University, Hohai University, Nanjing, Tianjin Polytechnic University and the Ministry of Water Resources Infrastructure Testing Center, the National Industrial Fabrics Testing Center and other research institutes to carry out research cooperation for many years, and maintain regular technology, trade exchanges and visits with the United States, Pakistan and other international geotechnical industries and enterprises, development of new products each year more than 10. In 2011, Edison patented 12, including four patents, utility model patents 8. Currently enterprises to participate in the drafting of the revised national standards for geosynthetics have six. This year there are two new enterprise products through scientific and technological achievements. Contribution rate of scientific and technological innovation of enterprises reached more than 70%. The first half of this year, the latest Geomembrane, corporate technology department with a half time to research the success of PDL Ballastless Track CRTSIII sliding layer of new products to the sliding performance, reduce rail vibration, to facilitate the construction, extension of life, etc. quality Geomembrane, a production would attract more than 3000 million orders, also apply to the State of New Railway Datong - Xi'an line construction. To study investigated the geomembrane geomembrane, especially the larger aperture woven fabric for protection engineering, natural waves, currents, tidal action of anti-scouring brush case, several non-woven geomembrane project intends to select applications (no woven fabric) and woven fabric (Table 5 -] 2 Pat, E6 two kinds of woven cloth), respectively, in the Liaohe River revetment project site, surrounded by Gulf Temple Xingcheng long seawall and Dawa River embankment Dipo conducted a field BRUSHING test. Test methods; the soil is protected weighed into the one. oM: 1.0m x o. 1M wooden box inside, according to a certain density compaction, geomembrane cover above, and fixed on the wooden frame, sub-capping layer (concrete panels, etc.) and not stamped on geotextile geomembrane layer in both cases, then the wood box set on the shore or Dipo withstand water, waves scouring brush, after "a given time, the heavy wooden remove said soil by measuring the moisture content before and after the test, particle analysis, soil erosion by protecting the soil around the stem weight and particle and other changes in the composition analysis, can be seen from Table 5-10, soil erosion after heavy basically greater than the previous erosion, not decreased, but increased. From the perspective of the soil particles, after scouring powder, tablets have taught increased analysis of the reasons is the geomembrane soil particle diameter greater than 7L Geomembrane best when water or wave impact cloth, it is possible to Ken river water, sediment box punch people, because geomembrane River sediment concentration test for 3.o-6.okdm3, the median size o. Tsukuda .o.026M. This shows that sediment concentration in the larger rivers, geomembrane will not cause a large aperture is scouring brush to protect the soil, you can use something todD oM design specifications. Professional Geomembrane, Edison new materials (certified), Yueyang Geomembrane new material provided by the Edison Company. Edison shares of new materials Ltd. (www.fangshenmo.com) is Dezhou, site construction materials leader, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Edison leadership with new material staff warmly welcome all inquiries negotiations to create new materials Edison a better future.
