摘　　要：钢筋混凝土原水引水渠道尺寸大,埋深深,水量大,同时一般不允许停水大修,因此漏水维修难度大。在大量维修实例的基础上,总结出一套行之有效的渠道带压外修的方法,即采用基础注浆加固、伸缩缝外贴止水带、外植钢筋浇筑混凝土加固渠道等措施,达到快速有效修复渠道的目的。The reinforced concrete raw water channel has large size,deep burial depth and high water flow.It is generally not allowed to carry out overhaul by cutting off the water supply,so leakage repair is of a great difficulty.Based on many repair practices,a set of effective external repair of channel with pressure are summarized,such as foundation is reinforced by grouting,water stop strip is set outside the expansion joint,cast reinforced concrete is used to reinforce the channel,to repair the channel quickly and effectively.

关 键 词：原水渠道 伸缩缝 带压堵漏 止水带
