| Abstract: | The exit part of Qinyu Tunnel on Wenfu Railway goes through shallow-buried and heavily weathered aqueous tufa area with a mud burst. Large-scale lead pipe roof combined with grouting with cement and water glass is adopted to stop the water burst, achieving the double purpose of lead support and grout strengthening. This paper introduces the successful application of this technology in construction. |
