摘要
城市地铁、隧道、地上道路、桥梁纵横交错,穿越既有地铁、隧道、高楼、河流、综合管廊等,实施过程繁琐,质量、安全要求高,本文研发的组合式施工技术可为城市建设工程的顺利实施以及既有地铁线路的安全运营提供保障:不仅与既有地铁相交区域的结构工程施工可按照预定工期顺利推进,还大大减少了处置安全隐患的投入,节约成本,增加城建工程的经济效益。
Urban subway,tunnel,ground road,bridge crisscross,through the existing subway,tunnel,high-rise building,river,comprehensive pipe gallery,etc,the implementation process is cumbersome,and the quality and safety requirements are high.The combined construction technology developed in this paper can provide guarantee for the smooth implementation of urban construction projects and the safe operation of existing metro lines:not only in the intersection area with the existing subway,but also with the existing subway The construction of structural engineering can be carried out smoothly according to the scheduled construction period,and at the same time,the investment in the disposal of potential safety hazards is greatly reduced,the cost is saved,and the economic benefits of urban construction projects are increased.
