在水位变幅较大的河、湖、水库中取水的泵站,一般是采用封闭井结构。即将所有机组安装在正常水位以下而且干燥的地下室内。此封闭井用混凝土或钢筋混凝土建成,止水材料要求较高,施工难度相当大,稍有不慎,机房渗水就会造成损失。这种结构投资投工都多,施工工期也长,管理操作很不方便,散热、噪音问题也难处理。为解决这些问题,山东省新太市水利水产局设计成功了一种新型结构,即浮动式扬水站。浮动式扬水站是依据阿基米德浮力定律和水涨船高的道理设计 Pumping stations that take water in rivers, lakes and reservoirs where the water level fluctuates are generally enclosed well structures. All units will be installed below the normal water level and dry basement. This closed well with concrete or reinforced concrete, water-stop materials require a higher degree of difficulty, construction is quite large, a little careless, seepage will cause damage to the engine room. This structure investment and more investment, construction period is also long, management is very inconvenient, heat, noise problems are difficult to deal with. In order to solve these problems, Shandong Xintai Bureau of Water Conservancy and Fisheries has successfully designed a new type of structure, namely floating pumping station. Floating pumping station is based on Archimedes buoyancy law and the soaring reason design
