水位变动较大河道环保疏浚与底泥处置方案

Environmental dredging and sediment treatment program in larger-fluctuation river

为解决水位变动较大河道的环保疏浚与底泥处置问题,基于山美水库进库河道段疏浚工程,总结如何合理地选择疏浚时机,采用适合特定水位下的疏浚设备统筹施工,利用太阳能自然干化降低底泥含水率,从而提高生产效率、节约成本,为后续工程提供经验借鉴。

To solve the problem caused by larger-fluctuation river of environmental protection dredging,the paper takes the environmental dredging project of Shanmei reservoir as an example to summarize the way of choosing reasonable dredging time,adopting the proper dredging equipment used for the specific water level,and using the natural drying of solar energy to reduce the water content of the sediment,and thus improve the efficiency and save the cost,to provide experience for the subsequent engineering.
