ANTI-OVERFLOW TYPE FILL DAM USING PARTIAL PAVEMENT SLOPE AND SLOPE CHANNEL

摘要

The present invention relates to a overflow breaking prevention type dam dam which quickly avoids the overflow water downstream of the body 10 so as to prevent the destruction of the body 10 due to abnormal overflow of the storage water. (10) A covering slope 12, which is a hydraulic covering, is formed on a portion of the upper end portion, and the inflow end is formed on the lower slope 20 of the body 10 at the lower portion of the covering slope 12. Connected to the outflow end is a sloped waterway 40 connected to the waterway 30 so that the abnormal overflow water quickly through the cover slope 12, the sloped waterway 40 and the waterway 30 to the downstream downstream of the dam. It can be excluded. Through the present invention, even without a large-scale construction, such as the increase of the body 10, the abnormal overflow of the dam dam, such as sudden changes in inflow due to abnormal floods, earthquakes, landslides or moon waves due to strong winds By constructing a facility that can quickly and stably remove city overflows, it is possible to economically secure the stability of the dam against the overflow of the body (10).
