浏醴高速公路双井隧道是全线唯一一座双连拱隧道,是全线重点、难点工程,也是控制性工程。中隔墙是双连拱隧道的主要结构体,主要结合双井隧道的特点及现场施工情况,重点通过对隧道的中隔墙设计、施工方案优化及中隔墙施工过程控制,探讨如何有效地提高中隔墙施工质量,加快隧道施工进度。 Shuangjing Liu-Li Expressway tunnel is the only one across the board double-arch tunnel, is the focus of the entire line, difficult projects, but also control engineering. The middle wall is the main structure of the double-arch tunnel. Based on the characteristics of the double-well tunnel and the construction conditions in the site, the design of the middle wall of the tunnel, the optimization of the construction scheme and the construction process of the middle wall are mainly discussed. Improve the quality of construction in the wall, speed up the construction progress of the tunnel.
