摘要:
总结归纳主要清淤方式及淤泥处置方式。从清淤效果、环境友好度、对河道行洪影响等方面对陆地挖掘机、水力冲挖机组、环保绞吸式挖泥船及抓斗式挖泥船等清淤方式进行对比分析,并结合二十埠河清淤工程,选择合理的清淤方式; 从减量化、无害化、稳定化等方面对自然脱水干燥法、真空预压脱水法、土工管袋法、搅拌固结法、脱水固结一体化法等淤泥处置方式进行对比分析,结合实际工程,选择合理的淤泥处置方式; 对工程实施过程中底泥有机质、总氮、总磷含量等营养物质污染情况的变化进行分析,为同类河道清淤工程提供了科学合理的依据和建议。
Abstract:
The main dredging methods and sludge disposal methods were summarized. The dredging methods of land excavator, hydraulic flushing unit, environmental cutter suction dredger and grab dredger were compared and analyzed from the aspects of dredging effect, environmental friendliness and influence on river flood discharge, and reasonable dredging method was selected combined with dredging project of Ershibu River. Sludge disposal methods such as natural dehydration drying method, vacuum preloading dehydration method, soil pipe bag method, stirring consolidation method and dehydration consolidation integration method were compared and analyzed from the aspects of reduction, harmlessness and stabilization, and reasonable sludge disposal methods were selected combined with practical engineering. The changes of nutrient pollution such as organic matter, total nitrogen and total phosphorus content in sediment were analyzed, which could provide scientific and reasonable basis and suggestions for similar river dredging projects.
