世界粮食计划署(简称WFP)援助广西农业综合开发3730项目象州县水利工程渠道防渗中,在原有砌石渠进行防渗的有101.2公里,分别占干渠防渗和总防渗长度的79.6%和83.8%,为了降低工程造价,利用原砌石渠进行改造,采取了在迎水面浇注砼或水泥砂浆抹面两种防渗措施;介绍了防渗设计结构形式、施工方法和工程造价;这些防渗措施已取得良好效果;最后提出了渠道防渗中存在的一些技术问题. WFP (Guangxi) assisted the anti-seepage of waterway in Xiangzhou Hydraulic Project in Project 3730 of Guangxi Comprehensive Development Project (WFP), with 101.2 km of seepage prevention in the original masonry canal, accounting for 79.6% of the total seepage prevention of canal and trunk canal respectively % And 83.8% respectively. In order to reduce the project cost, the original masonry canal was used for the reconstruction. Two kinds of seepage prevention measures were adopted, such as pouring concrete or cement mortar. The structure design, construction method and project cost were introduced Seepage control measures have achieved good results; Finally, some existing technical problems in canal seepage prevention.
