Because the baffles in water can increase the settling area of silt and decrease the settling distance of suspended articles,the settling efficiency will be raised greatly and the size of settling basin will be reduced as well.Some laboratory studies about using inclined-baffles to settling basin on water power channel are presented in this paper.According to the interrelationship of flow direction between baffles to slide direct...             在山区河流修建高水头引水式电站,当取水枢纽布置在狭谷河段时,由于地形条件限制,修建占地面面积较大的普通沉沙池往往十分困难。为寻求一种占地面积小而沉沙效率高的新型沉沙池,我们对斜板沉沙池进行了试验研究。根据模型试验结果,提出了适合水电站的斜板形式、较优的斜板相对长度计算沉沙效率的经验式以及斜板沉沙池布置形式等。 文摘来源          In the design of sediment tank for irrigation, a normal method is often used to determine the tank length. According to this method, the design length of the sediment tank used to deposit silt is very long. In this paper, a new method is presented to decrease the design length of the tank. After several schemes were compared by the aid of physical model experiment, an optimum measure to increase the deposit efficiency and operation period of the sediment tank is recommended.             本文简述了灌溉沉沙池以沉沙达到排清的设计思路及方法，针对沉淀粒径较细的粉沙质泥沙沉沙池设计长度较长的问题，结合具体工程模型试验实例，提出一种新的设计思路，即从沉沙池排出清水这一最基本要求出发，在有害泥沙还没有沉到池底时，从沉沙池含沙水流表层提取清水，以缩短沉沙地设计长度。最终，通过合理的工程方案和运行措施，达到提高沉沙效率、延长使用周期的目的。其基本原则可供此类沉沙池设计借鉴。 文摘来源          The existing problems of the desilting basin of Dayudu lifting project are considered to include serious seepage, non-smooth groundwater draining,poor stability of basin embankment and serious sedimentation in basin.Their causes are analysed,the countermeasures such as strengthening the seepage-prevention of basin bottom and side slope with reinforced concrete and geotechnical cloth,draining both inside and outside the basin,and sluicing by pressure pipeline are given finally.             大禹渡扬水工程枢纽沉沙池是解决枢纽二级站水泵磨损及灌区渠道淤积的关键工程。现沉沙池沉沙效率低下，严重制约了灌溉效益的发挥。本文从沉沙池的建造历史、工程地质、池身结构、泥沙淤积等方面对沉沙池存在的问题进行了综合分析。 文摘来源   << 更多相关文摘         相关查询: 沉沙 效率 变形效率 分配效率 加湿效率 办学效率 代谢效率 连接效率 潜热效率 效率基础 速度效率 脱硅效率  对查询结果不满意
