盾构法施工的水底公路隧道,隧道衬砌施工完成后再进行下风道、路面、腰墙等内部构构混凝土现浇施工,因而施工周期较长。上海延安东路隧道复线工程要在1995年年底通车,势必需要加快施工进度。为此,上海隧道工程股份有限公司立题开发一种在盾构隧道掘进同时,进行内部结构同步施工的工艺和技术。
Construction of the underwater tunnel tunnel construction, tunnel lining construction after the completion of the next duct, pavement, waist wall and other internal construction of concrete cast-in-place construction, and thus a longer construction cycle. Shanghai Yan’an Road Tunnel double-track project to be opened to traffic by the end of 1995, it is bound to speed up the construction schedule. To this end, Shanghai Tunnel Engineering Co., Ltd. legislation to develop a shield tunneling at the same time, the internal structure of the synchronous construction technology and technology.
