摘要
闽清县新建闽江取水泵站,采用江中取水方式。DN800×2引水管道采用沉管施工工艺。施工期间对原设计方案中水下挖槽与爆破、沉管定位、水下混凝土浇筑及取水头部安装等进行一系列优化,确保了该项目的顺利实施。施工期后又对管线进行复测,确保施工质量。项目建设投产已一年多,运行稳定。
Minqing County build new Minjiang pumping station,take water from the river. The DN800 × 2 water diversion pipeline using sinking construction process. During the construction of a series of optimization of dredging and blasting,sinking location,underwater concrete pouring and water intake structure installation,to ensure the smooth implementation of the project. After the construction of the pipeline to retest,to ensure the quality of construction. Project construction and operation has been more than 1 years,stable operation.
