【摘要】：錦屏一級(jí)水電站水庫(kù)死水位至正常蓄水位間水位變幅達(dá)80 m,且工程區(qū)兩岸地形陡峭,地質(zhì)災(zāi)害多發(fā),氣象條件復(fù)雜,旱季風(fēng)大,傳統(tǒng)形式的攔漂設(shè)施無(wú)法滿足電站運(yùn)行要求。結(jié)合工程現(xiàn)場(chǎng)實(shí)際情況,開(kāi)展了斜坡固定導(dǎo)槽水力自升降攔漂技術(shù)研究,介紹了其工作原理和設(shè)備安裝要點(diǎn)。實(shí)際運(yùn)行效果表明,通過(guò)采用斜坡式水力自升降連接裝置、防風(fēng)力翻轉(zhuǎn)破壞沉沒(méi)的攔污浮箱等新技術(shù),有效保障了攔漂系統(tǒng)運(yùn)行的穩(wěn)定性和安全性。
[Abstract]:The range of water level between dead water level and normal storage level of Jinping I Hydropower Station is up to 80 m, and the topography of both sides of the engineering area is steep, geological disasters are frequent, meteorological conditions are complex, the dry season is windy, and the traditional stoppage and drift facilities can not meet the operation requirements of the power station. Combined with the actual situation of the project, the hydraulic self-lifting drift technology of fixed guide tank on slope is studied, and its working principle and installation key points are introduced. The practical operation results show that the stability and safety of the drift arresting system can be effectively guaranteed by adopting new technologies such as slope hydraulic self-elevating connection device and anti-wind overturning and submersible anti-fouling floating box.
