Directory Yanhe Water Forever Environmental Control Engineering Of Rubber Dam And Sediment Dredging Scheme Analysis

In recent years, as a form of rubber dam water landscape projects favored by many cities in the country, along the historical process of its development, management level is constantly improving. In China Shanxi, Shaanxi and the two more serious soil erosion in the Loess Plateau, rubber dam on small river running has accumulated a wealth of operational management experience. However, due to arid areas in Northwest China belong to,precipitation, water scarcity, poor vegetation, soil erosion situation is extremely serious, and as the Loess Plateau region, which is even more serious. Yanhe is located in the hinterland of the Loess Plateau north of a river sediment concentration high, built on the river in a rubber dam will cause the flow velocity is too low to smuggle take a lot of sediment, which will lead to a lot of sediment off the silt on the riverbed Since deposition, we will increase the river slope, the water rises, thereby resulting in the deposition of new upstream will extend, over time will cause more severe siltation, continue to raise the riverbed downstream rubber dam continue to reduce the amount of such urban water supply, river landscape benefits, urban flood safety compromised, to the local people’s living inconvenience. The silting problem has always been with us for the presence of water, landscape works, which will directly affect the success of siltation works. So, for Yanhe Baotashan rubber dam dredging sediment analysis of significant issues.Taking Yanhe Baotashan rubber dam upstream segment of sedimentation as the research object, by access to large amounts of information, insight and analysis of siltation and water Yanhe Saudi Arabia, and to search the best siltation control measures in line with a view of the river Sedimentation formed for effective governance, providing a powerful guarantee the normal operation of Yanhe rubber dam water landscape projects. The main research work and achievements are as follows:(1) In-depth understanding of the Yanhe River silting of the city, based on a review of large amounts of data, a preliminary understanding of the current domestic commonly used sand dredging techniques to classify comparative analysis proposed water landscape Effective control measures Sediments problem.(2) After the fieldwork and analysis laboratory test data, a preliminary understanding of Yanhe sediment in water and sediment characteristics, by analyzing and summarizing a large number of test data to determine the rheological properties of different concentrations of sediment deposition under Analysis calculated Yanhe sediment in high concentration slurry pipeline transportation when the relevant parameters, and provide the basis for dredging pipeline design Sinotrans sediment.(3) The research data analysis, combined with the characteristics of the projects put forward countermeasures and their respective maintenance program Sinotrans sediment treatment.(4) project characteristics, proposed use of sediment were deposited heap Shaba program,dam design and preliminary analysis and calculation.
