INFLOW SEDIMENT PROCESSING METHOD IN DAM STORAGE LAKE

摘要

PROBLEM TO BE SOLVED: To provide an inflow sediment processing method in a dam storage lake in order to rationally remove sediment that flowed into and accumulated in the dam storage lake.SOLUTION: A inflow sediment processing method in a dam storage lake comprises following processes: raising a peripheral wall of a floating boat with buoyance for storing sediment dug out of a lake bed depending on an increase in the stored sediment; raising the peripheral wall by connecting and assembling blocks in stages whenever an inside of the peripheral wall is filled with the sediment; raising the peripheral wall to a required height depending on a set water level and filling the inside of the peripheral wall with the sediment; flattening the sediment surface by land elevation; and constructing a lake facility on the flattened surface.SELECTED DRAWING: Figure 1
