小天都水电站气垫调压室闭气补强的方案研究

Scheme Study on Air-Tight Reinforcement of Air Cushion Surge Chamber at Xiaotiandu Hydropower Station

小天都电站引水系统采用“一坡到底+气垫式调压室”方案,电站运行初期气垫调压室漏气量较大。本文介绍了气垫式调压室的设计和运行情况,介绍了气垫式调压室闭气补强处理方案比选、闭气补强处理施工与实施效果。

Abstractions: The diversion system of Xiaotiandu Hydropower Station adopts the scheme of "one slope to the bottom + air cushion surge chamber". The air leakage of air cushion surge chamber is large at the preliminary stage of the operation. This paper introduces the design and operation of air cushion surge chamber, and the selection of air-tight reinforcement treatment schemes for air cushion surge chamber, as well as the construction and implementation effect of air-tight reinforcement treatment.
