摘要
对宁夏灌区骨干渠道砌护情况进行了调查,分析了渠道结构破坏的形式、部位与程度,并对不同边坡砌护结构、渠底砌护结构和防渗、保温、排水方式的组合进行了试验研究。提出了适合寒冷地区的骨干渠道砌护三类模式:现浇混凝土坡脚、预制混凝土板坡脚、格宾石笼坡脚。选用砌护结构形式,要先确定渠身地下水位变化范围、边坡地质岩性、挖方渠道周围水环境,还要兼顾工程投资能力。
Based on the survey of the conditions of main canal lining in Ningxia,the analysis on the pattern,position,degree for structural destruction of the main canal lining,and the research on the combination of different lining structure for the slop and bed with seepage-proofing,keep warm and drainage,had been done.The three patterns including cast-in-site concrete,the precast concrete board and Gabion on the slope toe for the main canal lining,suitable for the local environment,have been put forward.When a lining structural pattern is selected,at first,we must consider water level under the canal bed,geological lithology in the slope and water environment around the canal,as well as construction investment ability.
