Reservoir deepwater sediment cleaning method
The invention provides a reservoir deepwater sediment cleaning method. The method comprises the following steps that, S1, underwater topography is detected, a desilting range according to the condition of reservoir sediments is determined, and excavation partitions are divided; S2, an assembled water surface operation platform and a negative-pressure silt pumping device reach the working position,the negative-pressure silt pumping device carries out desilting operation, and striping excavation is carried out; sediments pumped by the negative-pressure silt pumping device are conveyed into a slag collecting cage of the slag conveying barge; and the slag conveying barge moves to the shore, the slag collecting cage is hoisted to the shore, the sediments are loaded into a vehicle, and the vehicle conveys the sediments to a designated stacking place; S3, another excavation partition is chose, and the step S2 is repeated; and S4, desilting operation of all excavation partitions is completed,the underwater environment is detected again, and desilting operation is carried out again when necessary. The method is suitable for cleaning various sediments of various reservoirs, is simple and rapid to operate and high in dredging efficiency, and does not influence normal power generation of a hydropower station, sand discharging hole operation and flood discharging.
本发明提供了一种水库深水淤积物清理方法，包括以下步骤：S1：探测水下地形，根据水库淤积物情况确定清淤范围，划分开挖分区；S2：拼装式水面作业平台、负压抽淤装置到达工作位置，负压抽淤装置进行清淤作业，实行分条开挖；负压抽淤装置抽取的淤积物输送到运渣驳船的集渣笼内；运渣驳船移动到岸边，集渣笼吊到岸上，淤积物装入汽车内，汽车将淤积物运输至指定堆放地点；S3：更换开挖分区，重复步骤S2；S4：完成所有开挖分区清淤作业，再次探测水下环境，必要时进行再次清淤作业。本发明适用于各类水库的各类淤积物的清理，操作简单，快速，清淤效率高，且不影响水电站正常发电、排沙洞运行及泄洪。
