摘要
以某水利工程为例探究了农田灌溉防渗渠道的混凝土衬砌施工技术。现场调研发现灌区渠道存在塌方淤塞严重、输水不畅、水资源浪费等问题,决定采用混凝土衬砌方法。在修整地基和安装模板后,按照设计好的配合比制作混凝土并运输到施工现场。在浇筑混凝土后立即进行振捣、养护,提高其密实度和防渗性能。结果表明:农田灌溉渠道的输水顺畅、渗漏问题得到解决。由此可得,混凝土衬砌技术对提高水利工程中农田灌溉渠道的防渗效果以及提高水资源利用率有积极作用。
This paper explores the concrete lining construction technology of farmland irrigation seepage control channels as an example of a water conservancy project.On-site research found that the channels in the irrigation area have problems such as serious collapse and siltation,poor water transmission,and waste of water resources,so it was decided to use the concrete lining method.After repairing the foundation and installing the formwork,the concrete was made according to the designed mix ratio and transported to the construction site.Immediately after pouring the concrete,vibration and curing were carried out to improve its compactness and seepage control performance.The results showed that the water transmission of agricultural irrigation channels was smooth and the seepage problem was solved.From this,it can be concluded that concrete lining technology is positively helpful to improve the seepage prevention effect of farmland irrigation channels in water conservancy projects as well as to improve the utilization rate of water resources.
