隧道渗漏水是目前国内高等级公路中普遍存在的病害,这种病害往往与拱部二衬背后空洞和衬砌质量等问题密切相关。由于鲘门隧道病害的特殊性,传统的空洞灌注水泥砂浆方法受时间和工程造价限制,不能根本解决隧道渗漏水及其引发的稳定性等问题。鲘门隧道病害整治工程施工的实践表明,采用特殊的轻质土灌注设备和仰灌工艺可以有效将轻质土用于隧道空洞填筑。结合自钻中空锚杆锚注技术和混凝土喷射技术,可以取得良好的隧道病害整治效果和经济效益。
Tunnel water leakage is currently a common disease in domestic high-grade highways, and the disease is often closely related to the problems of cavities and lining quality behind the arch lining of the arch. Due to the particularity of the boredom tunnel, the traditional method of hollow grouting cement mortar is limited by time and engineering cost, which can not fundamentally solve the problem of tunnel seepage water and the stability caused by it. The practice of Chengmen Tunnel Disease Control and Reconstruction Project shows that the light earth can be effectively used for tunnel filling in tunnels by using special light soil perfusion equipment and Yang irrigation process. Combined with self-drilling hollow anchor bolt injection technology and concrete injection technology, can achieve good tunnel disease remediation effect and economic benefits.
