施工通道与浅埋超大断面地铁车站交叉口施工关键技术

Key Construction Technology for Intersection of Construction Passageway and Shallow-buried Subway Station with Super-large Section

施工通道与地铁车站交叉口处力系转换复杂,结构易失稳,制订科学可行的施工方案是保证施工安全和质量的关键。结合重庆轨道6号线五路口车站工程,通过对施工通道与车站交叉口原设计施工方案进行优化和改进,形成超大断面力系转换施工关键技术,施工效果较好,确保了交叉口施工的安全和质量,加快了施工进度。

The force system conversion is complicated in the intersection of construction passageway and subway station, and the structure is easy to lose stability, so scientific and feasible construction scheme is the key to guarantee the safety and quality of construction. In combination with the engineering of Chongqing metro line 6 with Wulukou station, the key construction technology of super-large section force system conversion is formed by optimizing and improving the original construction design scheme of the intersection. The key construction technology has a good implementation effect, which ensures the safety and quality of intersection construction, speeds up the construction progress.
