A dam equipped with a discharge device capable of discharging sediments downstream

摘要

The present invention relates to a dam equipped with an outflow device capable of discharging sediments downstream of a river bed. In the conventional dam, when water is discharged from the clear water in which the sediment in the upper layer is settled, the water in the lower layer is not discharged, Sediments continued to accumulate, causing enormous damage to the ecosystem upstream and downstream of the dam. In view of the above, the present invention provides a method of connecting a venturi pipe (2) (3) to both sides of a siphon outlet pipe (1) so that sediment in a lower layer of a dam is discharged at the time of discharge, And it is possible to protect the ecosystem around the dam by eliminating the harm caused by the sediment.
