最近几年,地铁在越来越多城市得到了普及,能够为人们日常出行提供便利,减少地表交通拥堵问题。盾构法是比较常见的地铁施工方法,可以减少施工期间对周边环境负面影响,而在不同地层,要求不同浆液配比来保证施工效果,需要技术人员做好合理配比设计。本文以某城市地铁工程1号线为例,对不同地层盾构同步注浆浆液配比技术进行了分析和探讨。
In recent years, the subway has been popularized in more and more cities. It can facilitate people’s daily travel and reduce the problem of surface traffic congestion. The shield method is a common subway construction method, which can reduce the negative impact on the surrounding environment during construction. In different strata, different slurry ratios are required to ensure the construction effect, and the technicians are required to make rational ratio design. Taking Metro Line 1 of a city as an example, this paper analyzes and discusses the grouting technology of shield synchronous grouting in different stratum.
