复杂艰险山区深埋隧道施工质量控制方法

Quality Control Method of Deep Buried Tunnel Construction in Complex and Dangerous Mountainous Area

为了在复杂艰险山区进行的深埋隧道工程更加牢固,应把握隧道施工的重要步骤,分析目前隧道质量问题产生的原因,有效地避开这些问题,为隧道工程提供更优秀的施工方法。在山区进行隧道建设,一要做好预应力支护,保证隧道建设的安全;二要采用“先注浆后挖”的方式,对隧道进行掘进;三要采用湿法喷射混凝土,在确保施工质量的同时,对工程项目产生一定的支撑作用,从而达到提升施工效率和安全性的目的;四要使用湿喷混凝土,使隧道稳定性更高,保障施工质量。

In order to realize the more solid deep buried tunnel engineering in the complex and dangerous mountainous areas,grasp the important steps in the tunnel construction engineering,analyze the causes of the current tunnel quality problems,effectively avoid these problems,and provide a better construction method for the tunnel engineering.To construct tunnels in mountainous areas,it is necessary to do a good job of pre-stressed support to ensure the safety of tunnel construction;The second is to adopt the method of"grouting before excavation"to excavate the tunnel;The third is to use wet sprayed concrete to ensure the construction quality and produce a certain supporting effect during the construction process,so as to achieve the goal of construction efficiency and safety;Fourth,by comparing the processes of dry sprayed concrete and wet sprayed concrete,it is found that using wet sprayed concrete can improve the quality stability of tunnel concrete and ensure the construction quality of tunnel engineering.
