Shield tunneling machine starting empty pushing section counter-force segment positioning device and installation method

The invention provides a shield tunneling machine starting empty pushing section counter-force duct piece positioning device and an installation method, and belongs to the technical field of underground engineering. The device is characterized in that first connecting holes are formed in a plurality of duct pieces, positioning assemblies are installed in the first connecting holes, and the positioning assemblies abut against the inner side wall of a starting empty pushing section; and the relative positions of the pipe pieces and the starting empty pushing section are adjusted, finally, under the condition that the tunnel shape is irregular, the multiple pipe pieces form a smooth arc-shaped structure, and finally, after concrete is poured, the pipe pieces are more stable, so that enough support is provided for the tunnel shield tunneling machine. 本发明提供盾构机始发空推段反力管片定位装置及安装方法，属于地下工程技术领域，其中装置包括：在多个管片上开设第一连接孔，将定位组件安装在所述第一连接孔内，并使定位组件与始发空推段的内侧壁抵接，调节所述管片与所述始发空推段的相对位置，最终在隧道形状不规则的情况下，使多个管片形成顺滑的弧形结构，最终浇筑混凝土后使管片更加稳固，以对隧道
