摘要
依托中梁山隧道下穿余家湾水库段高压富水区工程,详细介绍超前全断面帷幕注浆的施工方案;综合采用红外探水法、超前探孔法、检查孔法等,对注浆效果进行检验。开挖揭露后证明,岩溶裂隙和管道可以得到有效封堵,且注浆效果良好。
With Zhongliangshan tunnel traversing highpressure and rich-water zone under Yujiawan reservoir as the background, this paper introduces in detail the construction scheme of advanced whole-section curtain grouting. By using the infrared water detecting method, advanced borehole method, test hole method, grouting effect was inspected. It has been shown that grouting effectively pinged the karst fractures and pipelines and the grouting effect was good during excavation.
