摘要
在系统分析已建水库各种排沙方式的基础上,提出了小浪底水库自吸式管道排沙系统总体思路,即利用水库自然水头,在近坝段库区内铺设可移动并带有吸泥头、可逐渐加长的管道,自动地将坝前约40 km范围内淤积的细颗粒泥沙和通过过坝隧洞或右岸山体内的隧洞排出库外,初步估算每年可排出泥沙3亿t。排出库外的泥沙可采用管道进行远距离输送,实现泥沙资源化。同时指出,过坝方案、自吸式吸泥头体型研制、排沙管道等是该方案需要解决的关键技术问题。
Based on systematic analysis of various desilting methods by using existing reservoirs,the paper puts forward an overall thinking of desilting system of auto-suction pipe of the Xiaolangdi Reservoir,i.e.to automatically discharge the deposited fine sands within about 40 km area in foreside of the dam through dam tunnel or tunnel on the right bank of mountain by placing a removable and lengthable pipe equipped with a suction head in the near dam section of the reservoir area.It can discharge 300 million tons sediment each year by preliminary estimation.The discharged sediment can be long-distance transported through pipes,becoming sediment resources.It also points out that crossing dam plan,study and development of the shape of suction head and desilting pipe are the key technical issues that needs to be solved by the plan.
