| 摘 要： | 桥巩水电站二期下游土石围堰地质条件异常复杂,堰体存在着较多大块石,架空严重、空隙大、漏水量大,施工任务艰巨,同时由于度汛需要,施工工期比较短。通过综合采用高压旋喷灌浆、静压灌浆及膏浆堵漏等措施,使围堰取得很好的防渗效果,为在块石架空围堰进行防渗施工提供了一种有效、经济的施工技术。

| Abstract: | The geological conditions of the second stage of lower reaches earth-rock cofferdam of Qiaogong hydropower station are extremely complicated and bring about many problems,such as lots of large rocks around cofferdam body,big gap and extensive water leakage.Due to flood season,the construction period is rather short.The paper holds that the measures like high-pressure whirl-spray grouting,static pressure grouting and plaster grouting can prevent seepage effectively. |
