Influence And Protection Of Huma River Bridge Project On The Natural Conservative Area In Huma River

With the economic development in China, the expressway in China is also experiencing rapid development. However, many environmental problems have been confusing the people since then, especially the serious pollution caused by the expressway project passing through the natural water conservative area. So it is very important to make a research on the influence on the water environment caused by the cross-area bridge construction.The researching object in this paper is the influence of the old bridge transforming project of Huma River Bridge on the Huma River natural conservative area. Located in the downstream of Huma River with a distance of 11 kilometers to the estuary, The Huma River Bridge has passing through the national Huma River natural conservative area. Huma River Bridge is a bridge with a length of 408.96 meters and a width of 12 meters, and its crossing length is 189 kilometers. The Huma River natural conservative area is located in the central part of Greater Khingan Range in Heilongjiang province, including Huma river trunk stream and more than 200 tributaries.Through the detailed investigation in Huma River Nature Reserve Area of land utilization, plant resources, water, fish resources and other aquatic biological resources and objects of protection, to analyze the extent of influence of bridge construction to the major protected subjects, fish, vegetation, and biodiversity. The engineering environment predictors for the air are TPS, CO and NO2。The water quality of Huma River will be influenced by the bridge pier construction, according to the calculation of data sampling and monitoring, prediction of suspended sediment concentration in the water and influence distance, and determined to take the construction method of using steel plate to pile up the wading bridge.This paper presented the pollution control and prevention method of the Huma River. The main actions include.
