摘要
混凝土是我国渠道防渗工程主要采用的工程材料之一。但我国旧的混凝土防渗渠道经过输水运行后 ,存在着破坏现象 ,有的甚为严重 ,影响了工程的安全运行、效益发挥和防渗效果。为了合理修补改建此类工程 ,笔者根据自己的体会并参考有关资料 ,对旧混凝土防渗渠道破坏的原因及修补改建措施 ,提出初步意见 ,供讨论、交流和参考。
Concrete is one of major engineering materials used for canal seepage control in our country. Old seepage control canals with concrete have been damaged and some seriously through water conveyance and so the safety operation, benefits and seepage control effectiveness of the canals have been influenced. This paper puts forward the cause of damage of the canals and the measures to their repair and reconstruction to provide for discussion, exchange and reference.
