The Research Of Jiangyan Highway Ecology Design Engineering

Jiangmifeng to Yanji national highway is "five vertical and seven horizontal" National Road in the main trunk line with the country's Sanya Road to the main trunk line Changchun to Huichun Extension (GZ010-1) is an important component of the highway network in Jilin Province. Tts importance is self-evident, and do a good job of ecological design is imperative.Jiangyan highway is divided into jiangmifeng to huangsongdian, huangsongdian to Dunhua, Dunhua to Yanji three parts, along the natural landscape rich in China's temperate zones where most of the north, near-frigid zone, the seasons change significantly, dry spring Wind, high temperature wet summer, autumn day is mad crisply ,long cold winter; larger changes along the topography, hilly, lava platform, in the mountains, basins, valleys, and other types along the highway and across stream valley, including a second stream of the Songhua River-the River, the Songhua River Mudanjiang River Basin, Tumen river of the Boolean Kazak River Basin, the area is important in Jilin Province in the area of natural forest.Jiangyan highway landscape design under the general idea: closely focus on security, ecology, landscape, tourism Road objectives and requirements to ecological restoration main line, and give full play to plants in the Landscape, soft rigid Structure, shielding projects such as trauma the function. In the overall design of thought, the proposed safety principles, the principle of comfort, natural principle, the principle of harmony, economic principles, system principles, the principles of the model design principles.Highway landscape design goal is through the design of the linear landscape and environment highway landscape elements Integration, coordination. Green as principal measures to beautify the environment and restore the natural environment of the road on the injury. Along the customs and through the spread of the human landscape, an increase in road-domain environment cultural connotations, to the image of the United States appearance, strong environmental protection functions, the idea of strong cultural atmosphere on the main line landscape, the landscape facilities along the road side landscape, the road Side space detailed landscape design.Motor vehicles traveling on highways radiation noise, mainly due to the dynamic noise and tire noise constitute two parts. Proceeding from the actual needs of different noise-sensitive points at the situation using different noise reduction measures, there are sound barriers and noise reduction equipment on non-acoustic noise reduction barriers facilities design, these design is in the relevant norms under the guidance of the the fully made long-term planning to meet future for a very long time (design life) needs.Water environment design, the cross along the stream are more related to the protection of water resources in accordance with national laws and regulations do not set standards for the treatment of sewage to adopt corresponding measures. This paper Deck runoff water emissions Protection Design. Deck designed to collect sewage discharge pipe, design and the use of slow percolation of surface Sheet floodland treatment approach, and the Lafayette River water flow Ga ah smaller, wide river bed underneath a large open space areas , in the design of the bridge deck set up under the bed, "Gravel contact oxidation pond" Deck handle runoff. The design of sewage service area using "buried septic tanks + integration and sewage treatment facilities" treatment methods,management, toll stations, so centers in the water environment-sensitive areas, using simplified design secondary treatment process, "septic tanks + land treatment."In this paper the design done by the typical and representative, for the similar projects provide the basis for design and construction.
