摘要
实施大中型灌区改造的主要目标是完善灌排工程设施,提高灌区输水、配水效率和灌排保证率,改善农业生产条件。土渠输水渗漏严重,水量损失惊人。为了减少渠道输水损失、提高渠系水利用系数,应对渠道采取防渗衬砌措施。以河南省“十四五”大功灌区续建配套与现代化改造一期工程渠道设计为例,阐述渠道纵断面、横断面、结构设计特点、重点及技术分析,为更好提升渠道改造设计水平提供参考。
The implementing the transformation of large and medium-sized irrigation districts is constructed to improve irrigation and drainage engineering facilities,improve the efficiency of water transmission and distribution and the irrigation and drainage guarantee rate in irrigation areas,and improve agricultural production strips.The water loss caused by water leakage is serious.In order to reduce the water loss of the channel and improve the water efficiency in canal system,anti-seepage lining measures should be taken for the channel.Taking the channel design of the first phase of the continuous construction and modernization of Dagong Irrigation District in the"14th Five-Year Plan"of Henan Province as an example,the channel longitudinal section,cross-section,structural design characteristics,key points and technical analysis are elaborated to provide a reference for optimizing the design level of channel transformation.
