摘要
盾构管片是地铁盾构法施工工程中的关键预制构件,某地铁区间盾构隧道采用高精度预制钢筋混凝土管片,在管片加工前进行原材料检验,加工过程中对钢筋、模板、混凝土及构件养护等工序进行跟踪控制,对成品进行全面检查验收并抽样检测,确保了管片质量。
Shield segment is a key precast component of shield method in subway shield project.High-precision precast reinforced concrete segment is used in a shield tunnel project of a subway interval.The quality of shield segment is effectively guaranteed through inspection of raw materials before construction of shield segment,tracking control on such aspects as steel bar,formwork,concrete and component curing during processing of shield segment,and overall inspection,acceptance and sampling inspection of finished shield segment.
