某公路隧道工程二次衬砌的施工技术

摘要

In order to meet the requirements of modern highway tunnel construction, the structure of secondary lining is essential, its main functions are reinforcement, waterproof and drainage system optimization route, beautifying the appearance, convenient for setting, monitoring facilities such as com-munications, lighting, its construction quality is directly related to the durability and safety of tunnel structure. Combined with Zhaoqiao secondary neck rock highway tunnel project, this paper introduces the construction technology of tunnel secondary lining, offering some references for similar projects.%为适应现代化公路隧道建设的要求，二次衬砌是必不可少的结构，其主要作用为加固支护、美化外观、方便设置通讯、照明、监测等设施，其施工质量直接关系到隧道结构的耐久性和安全性。该文结合云南省昭通市昭巧二级公路齐头岩隧道工程，介绍了隧道二次衬砌的施工技术，可为类似工程提供借鉴。
