Subway protection system constructed close to existing subway bridge pile foundation and construction method
The invention relates to the technical field of metro tunnel protection structure and protection system construction, and provides a metro protection system constructed close to an existing metro bridge pile foundation and a construction method.The metro protection system comprises an MJS full reinforcement layer, a bridge bearing platform, the bridge pile foundation and an MJS reinforcement soil mass, and the MJS full reinforcement layer is arranged above an existing metro tunnel; the MJS reinforcing soil bodies are arranged on the two sides of the existing subway tunnel and the MJS full reinforcing layer, bridge bearing platforms are arranged on the two sides, away from each other, of the MJS reinforcing soil bodies, and bridge pile foundations are arranged at the bottoms of the bridge bearing platforms; the construction method comprises the following steps of construction preparation, lofting measurement, ditching, building of the cement paste mixing system and the sewage draining and water collecting system, and checking of the quality of the steel sleeve. Drilling a guide hole; the MJS grouting machine is inserted into a preset depth; the rotary equipment clamps the steel sleeve for rotary drilling; measuring the digging depth; according to the construction method, the existing underground subway can normally and stably run during bridge pile foundation construction, and operation continuity and construction safety and quality are guaranteed.
本发明涉及地铁隧道保护结构与保护体系施工技术领域领域，提供了临近既有地铁桥梁桩基施工的地铁保护体系及施工方法，地铁保护体系包括MJS满堂加固层、桥梁承台、桥梁桩基和MJS加固土体，MJS满堂加固层设在既有地铁隧道上方，MJS加固土体设在既有地铁隧道和MJS满堂加固层两侧，MJS加固土体相互远离的两侧均设置桥梁承台，桥梁承台底部设置桥梁桩基；施工方法，包括以下步骤，施工准备，放样测量，挖沟并修建水泥浆拌制系统与排污集水系统，检查钢套管质量；引孔钻进；MJS注浆机插入预定深度；回转设备夹住钢套管进行旋转钻进；测定挖掘深度；清理虚土，本申请在桥梁桩基施工时地下既有地铁可正常稳定运行，保证了作业的连续和施工的安全与质量。
