Construction method of subway station accessory structures
The invention relates to the field of rail transit engineering, and discloses a construction method of subway station accessory structures. The construction method comprises the following steps that the position of each accessory structure is determined according to a construction drawing; an open-cut part of each accessory structure is constructed, and a departure well of a pipe jacking machine is constructed on the open-cut part of each accessory structure; the circular pipe jacking machine is mounted in place in each departure well; the circular pipe jacking machine is constructed along each auxiliary structure line until all prefabricated pipe joints are mounted and the circular pipe jacking machine is jacked to the connector position of each subway station main body, and the sizes ofthe prefabricated pipe joints of all the auxiliary structures are the same; the circular pipe jacking machine is disassembled in situ, a shell of each pipe jacking machine is connected with the prefabricated pipe joints to form a subsurface tunnel section, and other disassembled components are transported back to the departure well and then hoisted out; a side wall at each connector position of the subway station main body and the accessory structure is broken; and a ring beam, internal structure and decoration of each connector position are conducted. According to the construction method, thebuilding scheme is standardized and modularized, the interference of construction on ground traffic is reduced, and the construction efficiency can be improved.
本发明涉及轨道交通工程领域，公开了一种地铁车站附属结构的施工方法，包括以下步骤：根据施工图纸确定各附属结构的位置；施工各附属结构的明挖部分，在附属结构的明挖部分上施作顶管机始发井；圆形顶管机在始发井内安装就位；圆形顶管机沿附属结构线路施工，直至全部预制管节安装完成且圆形顶管机顶进至与地铁车站主体的接口位置，各附属结构的预制管节的尺寸均相同；圆形顶管机在原地拆卸，顶管机外壳与预制管节连接形成暗挖隧道段，并将其余拆卸部件退运至始发井，再吊出；破除地铁车站主体中与附属结构接口位置的侧墙；施作接口位置的环梁、内部结构及装修：本发明使建筑方案标准化、模块化，降低施工对地面交通的干扰并能提高施工效率。
