湖南省水利部门在治理病险水利工程中,运用科学技术处理各种隐患险象。有7种行之有效的新工艺、新技术: 一、坝体劈裂灌浆防渗技术。运用坝体劈裂灌浆防渗技术工艺简单,操作容易,施工速度快,造价低。目前该项技术已用于46.5 m高的洋泉中型水库大坝和61.5 m高的黄材大型水库主坝的防渗工程。二、坝体坝基冲抓套井回填建造防渗墙技术。该项技术引进湖南后,已在10多处工程运用,成为一项成熟的推广技术项目。
Hunan Provincial Department of Water Resources in the treatment of dangerous water conservancy projects, the use of science and technology to deal with various hidden dangers. There are 7 kinds of effective new technology, new technologies: First, the dam body grouting seepage prevention technology. The use of dam body grouting seepage prevention technology is simple, easy to operate, construction speed, low cost. At present, this technology has been applied to the seepage control project of the main dam of Yangquan Medium Reservoir with a height of 46.5 m and the large yellow reservoir of 61.5 m. Second, the dam foundation Chongchuang well backfill construction cutoff wall technology. After the technology was introduced into Hunan, it has been used in more than 10 projects and has become a mature promotion technology project.
