摘要
针对渠道施工当中,经常发生的开挖过程中出现透水层导致施工期无法进行旱地施工问题及运行期渠道无水阶段边坡水压较大导致渠道衬砌混凝土或其他防护措施稳定性受到影响的问题,根据渠道工程结构及地质条件不同,采用盲沟结合逆止阀的渗控方案,以较经济适用的方式在渠道施工期及运行期达到排水、减压作用。并对提出施工难点要点以指导施工。
According to the problems that pervious bed occurred during the excavation process of channel construction prevents dry land construction during construction period and high hydraulic pressure of side slope affects the stability of channel lining concrete or other preventive measures during anhydrous stage of channel operation period, a seepage control scheme combined with blind drain and backflow barrier was used in the study on the basis of various channel engineering structures and geological conditions. The scheme could economically and serviceably real- ize drainage and decompressing effects during both channel construction and operation period. At last, the construction difficult and key points were proposed to guide channel construction.
