Zusammenfassung:The invention provides a tunnel segment secondary lining synchronous construction structure and method in the large-diameter slurry shield process. The construction structure comprises a tunnel duct piece, a prefabricated box culvert, a tunnel air duct embedded in the prefabricated box culvert and a duct piece secondary lining structure, the duct piece secondary lining structure comprises a duct piece upper secondary lining structure and arc-shaped short side walls located on the two sides of the prefabricated box culvert, and the lower edges of the two arc-shaped short side walls are in butt joint with the two sides of the prefabricated box culvert correspondingly. The upper edges are in butt joint with the end faces of the segment upper secondary lining structure, and the thickness of the arc-shaped short side wall is matched with the thickness of the segment upper secondary lining structure. The tunnel segment secondary lining synchronous construction structure further comprises temporary pipeline supports
