ANTI-OVERFLOW TYPE FILL DAM USING CREST PAVEMENT AND INTERMEDIATE CHANNEL

摘要

The present invention relates to an overflow destruction prevention dam which avoids overflow of the overflow water downstream of the outflow body 10 so as to prevent the destruction of the body 10 due to abnormal overflow of the stored water. An intermediary canal (40) connecting the government road (11) and Yeosu (30), which is a scientific cover, is installed, and the entire government road (11) is located on the downstream side of the government road (11). The barrier wall 12 is installed over the extension, and the longitudinal line of the government road 11 forms an inclination so that the elevation is gradually lowered toward the connection side of the intermediary channel 40 at the start and end points of the government road 11, Absolute overflow water is to be quickly excluded from the dam downstream through the government road (11), intermediary channel (40) and Yeosu channel (30). 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).
