摘要
本文针对隧道二次衬砌拱顶脱空问题,在分析成因的基础上,提出了隧道防水板挂设工艺及隧道拱顶混凝土真空辅助灌注施工方法,并详细介绍了技术原理和施工步骤,以期对类似工程提供参考和借鉴。
In this paper,based on the analysis of the cause of the hollowing of the tunnel's secondary lining vault,this paper puts forward the installation technology of the tunnel waterproof board and the construction method of the vacuum-assisted pouring of the vault concrete,and introduces the technical principle and construction steps in detail to provide reference for similar projects.
