经调查,当前小型水库存在的问题很多:一是进出水涵洞止水失效。84座水库中洞身侧墙、翼墙渗水、漏水严重的有19座,占22.6%。有的放水涵洞接头处理不好,无止水,造成洞身严重渗漏。二是进出水涵洞底板或侧墙被淘空、断裂及消力池被冲毁。新沂县新潮水库放水涵洞底板在距闸门后8米处,洞身侧墙断裂了2/3,漏水严重。白石水库溢洪道下游消力池冲毁,已危及工程安全。三是土坝体单薄,无戗台和滤水设施,土坝背水坡有明显的渗流。如铜山县水口水库东西老坝长750米无戗台和滤水层,坝背水坡渗水严重。不少水库土坝成段下陷,一般在10多厘米,局部沉陷达30至70厘米,有的坝身獾鼠打洞穴居。铜 After investigation, the current problems of small reservoirs are many: First, out of culvert water stop failure. In the 84 reservoirs, there are 19 holes in the side walls and water walls in the walls, accounting for 22.6%. Some drainage culvert joints are not handled properly, there is no water, resulting in serious leakage hole. The second is the inlet and outlet culvert floor or the side walls were Amoy, broken and dissipating pool was destroyed. Xinyi County Xinchao reservoir drainage culvert floor at a distance of 8 meters from the gate, the hole in the side wall break 2/3, serious water leakage. Shiraishi reservoir spill downstream trough destroyed, has endanger the safety of the project. Third, the earth dam body is thin, no taiwan and drainage facilities, earth dam back slope obvious seepage. Such as Tongshan Shuikou reservoir east and west of old dam 750 meters without taiwan and drainage layer, dam water seepage serious. Many reservoirs into subsidence dam, generally more than 10 cm, partial subsidence of 30 to 70 cm, and some dam body badger burrow home. copper
