Super-large section highway assembly type arched tunnel structure and construction method thereof
The invention discloses an ultra-large section highway assembly type arched tunnel structure and a construction method thereof, and belongs to the technical field of tunnel construction.The structure comprises annular prefabricated structures which are sequentially spliced in the longitudinal direction, and each annular prefabricated structure comprises a cast-in-place inverted arch structure, a tunnel prefabricated structure A and a tunnel prefabricated structure B; the upper end of the tunnel prefabricated structure A and the upper end of the tunnel prefabricated structure B are matched with each other to form an arch shape, and the lower end of the tunnel prefabricated structure A and the lower end of the tunnel prefabricated structure B are connected with the two ends of the cast-in-place inverted arch structure correspondingly. Every two adjacent annular prefabricated structures are spliced through a concave-convex mortise structure. According to the structure and the construction method thereof, the rigidity and stability of the tunnel can be guaranteed, certain economical efficiency and attractiveness are achieved, the tunnel structure is constructed by adopting a duct piece prefabrication and field assembly method, the tunnel structure is in a sectional type, the waterproof effect can be guaranteed, and the construction cost is reduced. And the normal operation and the service life of the fabricated tunnel in the whole life cycle are not influenced.
本发明公开了一种超大断面公路装配式拱形隧道结构及其施工方法，属于隧道施工技术领域，结构包括沿纵向依次拼接的环形预制结构，每一环形预制结构包括现浇仰拱结构、隧道预制结构A和隧道预制结构B，所述隧道预制结构A和隧道预制结构B的上端相互配合呈拱形，所述隧道预制结构A和隧道预制结构B的下端分别与现浇仰拱结构的两端连接；相邻两个环形预制结构之间通过凹凸榫槽结构相互拼接。本发明结构及其施工方法既可以保证隧道的刚度和稳定性，又具有一定的经济性和美观性，并且采用管片预制、现场拼装的方法进行建设，隧道结构呈分段式的形式，能够保证防水效果，不会影响装配式隧道在全生命周期的正常运营和使用寿命。
