岭头亭隧道湿喷混凝土施工科技推广应用

The Lingtou Pavilion tunnel wet spraying concrete construction technology popularization and application

喷射混凝土是隧道初期支护的重要组成部分,是提高支护结构整体刚度,有效控制围岩变形,改善隧道结构的应力分布状态,减少隧道突发性坍塌发生的重要工序。隧道湿喷混凝土施工工艺在我国正在广泛推广应用,本文结合岭头亭隧道湿喷混凝土技术的应用情况,对材料配备、机械选用、工艺原理等作了简单分析和论术。

The shotcrete is an important part of the tunnel initial support is to improve the overall stiffness of the supporting structure,effective control of the surrounding rock deformation,stress distribution to improve the structure of the tunnel,an important process to reduce the sudden collapse of the tunnel.Tunnel wet shotcrete construction technology in China is widely promote the application of this article combined with Lingtou kiosks tunnel wet sprayed concrete technology,with the material,mechanical selection process principles were simple analysis and on the surgery.
