Suizhou Drainage Pipe Manufacturer - Supply Railway Bridge Drainage

Description :

　　Suizhou Drainage Pipe Manufacturer - Supply of Railway Bridge Drainage In the 1980s, China began exploring ecological environment construction. The first National Symposium on Urban Ecology held in Shanghai in December 1984 is considered a milestone in the research of ecological cities in China. In the same year, the Urban Ecology Committee of the Chinese Ecological Society was established; In 1986, Yichun City in Jiangxi Province, China proposed the development goal of building an ecological city and carried out pilot work in early 1988, which was the second specific practice of ecological city construction in China. After launching the pilot project of ecological city construction in Yichun City, Jiangxi Province, China carried out 154 ecological demonstration zone construction pilot projects in four batches from 1996 to 1999, including 2 ecological provinces, 16 ecological areas and cities, 29 ecological counties (cities), and 7 others.

　　Characteristics and uses of bridge drainage pipes

　　Bridge drainage pipes mainly undertake the tasks of rainwater and highway drainage.

　　Bridge drainage pipe, suitable for paving structures with waterproof layers. The inner diameter of the drainage pipe is generally 0.10-0.15m, and the lower end of the pipe should extend at least 0.15-0.20m below the bottom of the roadway slab to prevent moisture from seeping into the surface of the main beam ribs. The pipe body is smooth, free of sand holes, and has a long service life. It is a good choice for drainage systems on highways and railways.

　　Installation and usage instructions for drainage pipes:

　　1. The construction of the drainage pipe should be carried out according to the design requirements. The drainage pipe should extend no less than 30mm from the bottom of the structure, and the longitudinal spacing should not exceed 4m.

　　2. For bridges on overpasses, the drainage pipe should not be directly hung under the slab. The drainage pipe can be directly led to the ground through longitudinal and vertical drainage pipes

　　3. Cast iron drain pipe, suitable for paving structures with waterproof layers. The inner diameter of the drainage pipe is generally 0.10-0.15m, and the lower end of the pipe should extend at least 0.15-0.20m below the bottom of the roadway slab to prevent moisture from seeping into the surface of the main beam ribs.

　　In 1996, Weihai City put forward the guiding principle of urban construction of "not seeking scale, but seeking beauty", and put it into practice in the overall concept of ecological city construction of "modernization of infrastructure, ecologicalization of urban environment, rationalization of industrial structure, and civilization of living quality". Since the beginning of the new century, cities such as Shanghai, Guangzhou, Xiamen, Ningbo, Harbin, Yangzhou, Changzhou, Chengdu, Zhangjiagang, Qinhuangdao, Tangshan, Xiangfan, Shiyan, and Rizhao have proposed to build ecological cities. Provinces such as Hainan, Guizhou, Shandong, Jilin, and Anhui have set the goal of building "ecological provinces" and have carried out extensive international cooperation and exchanges. Among them, the collaborative research on "Yangzhou Ecological City Planning and Management" conducted by China and Germany is an example. In April 2006, the Ministry of Construction planned to compile the "Scientific Evaluation Standards for Livable Cities" and included the "Research on the Scientific Evaluation Index System for Livable Cities" as a soft science research topic for 2006. On August 7, 2006, in the approval of the overall urban planning of Tianjin, it was also stated that Tianjin would be positioned as an international port city, a northern economic center, and an ecological city. These fully reflect the beautiful aspirations of the Chinese people for building new ecological cities, indicating that building ecological cities is the mainstream direction of urban development in China. Through the vigorous implementation of the demolition of illegal constructions and green projects nationwide in recent years, the area of gardens and green spaces has continued to increase, and the living environment has been continuously improved.
