摘要
辽宁省大伙房水库输水工程施工支洞控制段,因地质条件原因右侧拱肩位置突发大量涌水,高峰涌水量为3000m3/h,涌水迅速漫延整个洞室。为封堵水源,经专题研究确定采用"盖帽法"灌浆施工。介绍工程地质及"盖帽法"施工技术及应用效果。
The artesian water occurs in the right spandrel of drift for water conveyance project in Dahuofang reservoir, the peak artesian water quantity is 3000m3/h and draws out in the cavern. The 'capped method' grouting is applied for closing artesian water, the paper introduces the engineering geology and the 'capped method' construction and the application effect.
