摘要
帷幕注浆处理隧道内涌水施工技术,对保证隧道安全穿越围岩节理发育的高压富水区,避免突发性涌水、突泥发生具有明显效果。宜万铁路别岩槽隧道施工中采用此项技术,保证了隧道施工的正常进行。介绍施工方案的设计及具体实施过程,例如采用的设备、材料和关键施工技术,对同类工程有借鉴意义。
The grout curtain technique is proved very effective in the treatment of gush water inside tun-nels, with obvious efficiency in dealing with gush water inside tunnels through water-rich regions and preventing sudden gush of underground water and mud. With this technique adopted for the construction of the Bieyancao Tunnel of the Yi-Wan Railway, the smooth construction of the tunnel is ensured. The design of construction plans for the tunnel and the practical implementation of the plans are dealt with in the paper, with construction equipment, materials and key techniques adopted for the project made known. It may serve as a reference for similar projects.
