Fork, is connected to by clear water bypass passageways.
The settling pit uses the more compartment arragement constructions of multicell, and each equal independent operating in pond compartment, the first water transport channel end passes through
Multiple bifurcation gates divide water, then are connected to respectively with the more compartment head ends of settling pit multicell by multiple clear husky gates, and settling pit multicell is more
The end in compartment is connected to by being vented gate with sand discharge channel, is provided with regulating gate in clear water bypass passageways.
The conveyance capacity of first water transport channel designs punching according to the design inflow-rate of water turbine and settling pit of the second water transport channel
The summation of sand drift amount designs.
The clear water bypass passageways conveyance capacity is identical as the second water transport channel conveyance capacity, clear water bypass passageways and desilting
The opening and closing control that the alternate run in pond passes through bifurcation gate and regulating gate.
Channel in first water transport channel, the second water transport channel, sand discharge channel and clear water bypass passageways refer to tunnel,
Open channel or pipeline.
The beneficial effects of the present invention are: collection sand flushing system reduces artificial and mechanical removal during water sand separation facility operation
The workload of desilting, and can realize that the high-efficiency and economic of silt in water utilizes；Clear water by-pass tunnel channel improves water intake engineering
Water supply fraction.
