孤石滩水库始建于1958年,位于淮河流域沙河支流澧河的上游,坝址在叶县西南常村乡的小呼沱村上游约600m处。总库容1.845亿m~3,是一座以防洪、溉灌为主,结合发电、养鱼等综合利用的大(2)型水库。经过多年的运行,由于不断地热胀冷缩变化等原因,在溢洪道的上下游翼墙、闸墩闸墙、溢流面、消力池两岸边墙等部位出现多处裂缝,长2～9m,缝宽1～8mm,缝深不一,有的成为贯穿砼墙体的通缝,地下水从中溢出。化学灌浆的目的,就是对裂缝进行填实修补,遏制裂缝的
Founded in 1958, Bessatan Reservoir is located in the upper reaches of Bahe River, a tributary of the Shahe River in the Huaihe River basin. The dam site is about 600m upstream of Xiaotutuo Village, Changcun Township, southwest of Yexian County. With a total storage capacity of 184.5 million m3, it is a large (2) type reservoir that integrates power generation and fish farming for flood control and irrigation irrigation. After years of operation, multiple cracks occur in the upper and lower wing walls of spillways, sluice gate walls, spillway surfaces, and both sides of the shoaling basin due to the constant thermal expansion and shrinkage changes. The cracks are 2 to 9 meters in length, Slit width 1 ~ 8mm, seam depth varies, and some become through the concrete wall through the seam, groundwater overflow. The purpose of chemical grouting is to crack fill fill repair, to curb cracks
