Fabricated tunnel bottom structure replacing inverted arch filling layer and construction method
The invention relates to the technical field of highway tunnels, in particular to a fabricated tunnel bottom structure replacing an inverted arch filling layer and a construction method. The fabricated tunnel bottom structure is mounted on a cast-in-place reinforced concrete inverted arch; the fabricated tunnel bottom structure comprises a prefabricated UHPC mouth-shaped component, a prefabricated reinforced concrete carriageway plate and a cast-in-place concrete bracket; the prefabricated UHPC mouth-shaped component is longitudinally fixed on the cast-in-place reinforced concrete inverted arch; the cast-in-place concrete bracket is poured on the cast-in-place reinforced concrete inverted arch and an existing secondary lining; the prefabricated reinforced concrete carriageway plate is laid through the prefabricated UHPC mouth-shaped component and the cast-in-place concrete bracket; and a pavement structure layer is laid on a plane formed by the prefabricated UHPC mouth-shaped component and the prefabricated reinforced concrete carriageway plate. The structure is reasonable in structural design, easy and convenient to construct and good in using effect.
本发明涉及公路隧道技术领域，具体为一种替代仰拱填充层的装配式隧底结构及施工方法；所述装配式隧底结构安装于现浇钢筋混凝土仰拱上，所述装配式隧底结构包括预制UHPC混凝土口型构件、预制钢筋混凝土行车道板和现浇混凝土牛腿组成，预制UHPC混凝土口型构件纵向固定于现浇钢筋混凝土仰拱上，现浇混凝土牛腿浇筑于现浇钢筋混凝土仰拱和既有二次衬砌上，通过预制UHPC混凝土口型构件和现浇混凝土牛腿铺设有预制钢筋混凝土行车道板，在预制UHPC混凝土口型构件和预制钢筋混凝土行车道板形成的平面上铺设路面结构层。本结构结构设计合理、施工简便且使用效果良好。
