地铁预制混凝土衬砌管片损伤修复关键技术

The key technology for damage repair of reinforced concrete segments of subway

预制混凝土衬砌管片是地铁工程最重要和最关键的衬砌结构构件,预制管片生产工艺要求严格,详细介绍了地铁预制管片损伤修复材料、材料配合比、修复方法,为类似地铁管片预制混凝土构件生产提供参考。

Precast concrete lining segments are the most important and most important lining structural members of subway engineering. The production process of prefabricated segments is strict. This paper introduces the damage repair materials,material mix ratio and repair methods of subway prefabricated segments,which are similar to subway segments. Production provides a reference.
