以莆永高速公路格口隧道工程为背景,通过中导洞提前进洞、改进出渣方式、改变中隔墙施工顺序等措施加快连拱隧道中导洞施工,并进行了施工工期对比分析,结果表明,采取以上措施能够加快中导洞施工速度,节约施工工期,可为类似工程施工提供借鉴。
Taking the Puguang Expressway Gekou Tunnel project as the background, the construction of pilot tunnel in the double-arch tunnel was accelerated through the advancement of the tunnel in the pilot tunnel, the improvement of the slag removal mode and the change of the construction sequence of the intermediate partition wall. The contrastive analysis of the construction period was carried out, The results show that taking the above measures can speed up the construction of the pilot tunnel and save the construction period, which can provide reference for similar projects.
