摘要
盾构区间的联络通道一般采用矿山法修筑,不同地区不同地层应采用不同的辅助工法,以成都地铁盾构区间的联络通道为例,详细介绍了工程及地层特点,阐述富水砂卵石地层施工降水、大管棚施工、暗挖法开挖以及结构混凝土的组织运输和浇筑的施工技术。
A connected aisle of shield-driven running tunnel is usually constructed by the mine tunneling method.Different auxiliary construction method will be adopted in different stratum.Taking the connected aisle of Chengdu Metro shield-driven running tunnel as an example,the characteristics of the program and the stratum are introduced in detail.In addition,construction technology of dewatering,large-pipe umbrella arch,mining method excavation,transportation and pouring of structure concrete in water-rich sandy cobble stratum are also analyzed.
