LUO NINGNING / LUO KANGYONG / LIU GUOHUI

The invention discloses a construction method of a subway vehicle section pipe gallery. The construction method comprises the following steps that a pipe gallery to be constructed is divided into a plurality of pipe gallery sections which are connected in sequence, each pipe gallery section is correspondingly constructed, the construction of each pipe gallery section is to excavate a foundation pit first, and then a bottom plate of a reinforced concrete structure, side walls of the reinforced concrete structures on the two sides and a top plate of the reinforced concrete structure are constructed in the foundation pit, a pipe culvert structure of the pipe gallery section is obtained, and finally the foundation pit is backfilled. The construction method has the advantages of being high in construction efficiency and safety, capable of greatly reducing influences on construction of an upper cover vehicle depot main body structure and traffic transportation and the like.

本发明公开了一种地铁车辆段管廊的施工方法，该施工方法是先将待施工管廊分成依次相接的多段管廊段，对每段管廊段分别进行施工，各管廊段的施工是先开挖基坑，再在基坑中施工钢筋混凝土结构的底板、两侧钢筋混凝土结构的边墙和钢筋混凝土结构的顶板，得到管廊段的管涵结构，最后再回填基坑。该施工方法具有施工效率高、安全性高、可大大减少对上盖车辆段主体结构施工以及交通运输的影响等优点。
