在我国农田灌溉中,渠道输水是灌溉的主要方式,但传统的农田灌溉主要以土渠作为输水渠道,但这种方式的水渗透程度较大,不仅严重浪费了水资源,更严重的是导致了土地溃害。在这种情况下,具有很好的防渗效果的混凝土衬砌施工,已经在水利工程建设之中得到了很好地运用,从而保证了农田的灌溉防渗效果,提高了灌溉的耐久性。本文主要对农田灌溉防渗渠道衬砌施工技术进行了研究,并对技术中的有关问题提出了一些改进措施,从而更好的确保渠道施工的安全性和经济性。
In China’s farmland irrigation, water conveyance by channels is the main way of irrigation. However, the traditional farmland irrigation uses mainly soil canals as the water conveyance channel. However, the water penetration in this way is rather large, not only seriously wasting water resources but also more serious It caused the land to be destroyed. Under such circumstances, concrete lining construction with good anti-seepage effect has been well utilized in the construction of water conservancy projects, thus ensuring the irrigation seepage prevention effect of farmland and improving the durability of irrigation. This paper mainly studies the construction technology of irrigation and drainage canal lining in farmland, and puts forward some improvement measures to the related problems in the technology so as to better ensure the safety and economy of canal construction.
