摘　　要：以非洲某供水项目为例,结合项目所在国资源,因地制宜,探讨非洲地区水下管道施工的具体技术措施,包括实测湖底标高、湖内管道固定、水下管道安装、管道悬浮在湖水表面、管道的打压和沉水,并提出了供水项目水下取水管道施工质量控制措施。实践证明,这些技术措施在该工程中取得了良好的实施效果。Based on a water supply project in Africa,combined with the resources of the host country,adjust measures to local conditions,the specific technical measures for underwater pipeline construction in Africa are discussed,including measuring the elevation of the lake bottom,fixing the pipeline in the lake,installing the underwater pipeline,suspending the pipeline on the lake surface,suppressing and sinking the pipeline,and the quality control measures for the construction of the underwater water intake pipeline of the water supply project are put forward.Practice has proved that these technical measures have achieved good implementation results in this project.
