前言无论土建还是机电项目,在正常营运收费中的高速公路隧道中进行土建或机电改造工程施工,都必须实施长时间的单洞封闭,会给所在的营运高速公路业主单位和当地交警部门带来很大交通安全压力;因此此类隧道改造工程往往工期短,受到各种客观条件限制多,因此如何在隧道正常通车的情况下保证工程的工期和质量,尽量做到少封洞、少返工和少变更,是我们整个工程项目施工的前提。
Preface Regardless of civil construction or mechanical and electrical projects, civil engineering or electromechanical reconstruction works in highway tunnels under normal operating charges must be implemented for a long time single-hole closed, will be brought to the owner of the operating highway and the local traffic police department Therefore, such tunnel reconstruction projects often have short construction periods and are subject to various objective conditions. Therefore, how to ensure the construction period and quality under normal tunneling conditions, minimize the number of closed tunnels and minimize rework and Less change, is the premise of the construction of our entire project.
