Research and application of integrated techniques for internal control and hydraulic excavation of river channels
To study the internal pollution control methods of river channels,analyze the flood control standards and water quality output targets of river channels,determine the scope of dredging and construction methods for polluted river channels.Analyzed the tidal water level and flood discharge capacity of the river channel,delineated the dredging range and longitudinal dredging depth.Analyze the load of endogenous pollutants and the physicochemical properties of sediment,and determine the thickness of river dredging and mud treatment requirements.In order to achieve environmental protection and dredging construction in river channels,the hydraulic flushing and dredging construction method is adopted to effectively remove target pollutants and reduce the amount of river dredging.By controlling the transmission pressure of the multi-stage pumping system,long-distance and steep slope mud transmission is achieved.
