Abstract
It is of great significance to carry out the river and lake ecological dredging project actively for the river and lake water ecological management.Taking Nanyi Lake in Xuancheng,Anhui Province as an example,the feasible scheme of ecological desiccation of lake was developed based on the actual characteristics of the experimental area.The results showed that following the concept of"dynamic adjustment"and zoning desilting in the lake,the scheme of"surface sediment dredging +deep dredging"was adopted,and the dredging amounts of the first and second districts were 2.4772 and 13.8938 million m3,respectively,which could meet the water quality standards.The surface sediment dredging machine adopted the cutter suction dredger,while the deep dredging machine adopted the special working boat to suck and transport to the temporary designated point and then transfer.At the same time,the economy,technology and environmental protection of three kinds of silt consolidation technologies,such as vacuum prepressing,mechanical dehydration integration and geotechnical pipe bag consolidation were compared and analyzed.The geotechnical pipe bag consolidation technology was finally recommended to consolidate the silt into soil in Nanyi Lake.The research results can provide useful reference for similar river and lake desilting projects.关键词
