水库由无砂混凝土管渗流取水能力与效率试验研究

根据渗流理论，结合工程实际，以不同配比的无砂混凝土管为研究对象，探讨无砂混凝土管在不同粒径滤料的颗粒级配和多种防冲层材料条件下对渗流取水效能所产生的影响和变化规律。根据试验结果可以得出：水库采用无砂混凝土管取水的能力是可观有效的，滤料颗粒继配良好，防冲层为无砂混凝土板时无砂混凝土管的渗流能力和取水效率较为理想。

Experimental Study on the Seepage Water Abstraction using Unsanded Concrete Tube in the Reservoir

According to the seepage theory, combined with the engineering practice, this paper different proportions of unsanded concrete tube is the research object, discussed in the absence of the size of the porosity of the sand concrete pipe, different filter material particle size grading, bumper material on the impact of seepage water efficiency and change rule. According to the experimental results can be concluded that unsanded concrete pipe reservoir water is considerable effective. With good particle filter, when scour protection is the unsanded layer concrete slab that the water flow capacity and efficiency is better.
