The invention belongs to the technical field of underground structure engineering, and particularly relates to a shield tunnel internal lane structure and a construction method. The shield tunnel internal lane structure comprises lane plates and lane columns. The lane plates comprise a prefabricated lane plate and a cast-in-place concrete lane plate; and the two ends of the prefabricated lane plate are installed on brackets of the lane stand columns on the two sides of the prefabricated lane plate respectively, and cast-in-place concrete lane plates are poured between the prefabricated lane plate and the lane stand columns and on the prefabricated lane plate. The lane plates adopt a superimposed structure of the prefabricated lane plate and the cast-in-place concrete lane plate so that a formwork supporting procedure can be reduced, a mold is saved, a construction period is shortened, the prefabricated lane plate can be produced on a factory assembly line, construction is convenient, quality is easy to control, and requirements of rapid construction of the internal structure of a tunnel and a performance structure of the lane plate can be satisfied; in addition, concrete is pouredbetween the prefabricated lane plate and the lane stand columns and on the prefabricated lane plate to form the cast-in-place concrete lane plate, and integrity of the prefabricated lane plate, the cast-in-place concrete lane plate and the lane stand columns is improved.
本发明属于地下结构工程技术领域，具体涉及一种盾构隧道内部车道结构及施工方法，包括车道板和车道立柱，车道板包括预制车道板和现浇混凝土车道板；预制车道板的两端分别安装于其两侧的车道立柱的牛腿上，预制车道板与车道立柱之间以及预制车道板上浇筑有现浇混凝土车道板。本发明中车道板采用预制车道板加现浇混凝土车道板的叠合结构，不仅可以减少支模工序，节省模具和工期，而且预制车道板可以在工厂流水线上生产，施工方便、质量易控制，从而能满足隧道内部结构快速施工及车道板性能结构的需求；此外，预制车道板与车道立柱之间以及预制车道板上浇筑混凝土形成现浇混凝土车道板，提高预制车道板、现浇混凝土车道板与车道立柱的整体性。
