The invention discloses an immersed tube tunnel and a construction method. The immersed tube tunnel is formed by connecting a plurality of cylinders end to end in a butt joint mode, wherein each cylinder is cylindrical and comprises a cylinder wall, a first rib plate, a second rib plate, a third rib plate, a fourth rib plate and a fifth rib plate; the two ends of the first rib plate are connectedto the inner wall of the cylinder wall; and the central axis of the cylinder is positioned on the plane where the first rib plate is positioned. The cross section of each cylinder of the immersed tubetunnel is round, compared with a traditional immersed tube with a rectangular cross section, the thickness of the cylinder wall of each cylinder can be reduced as much as possible while the pressurebearing capacity of the cylinder is guaranteed, the production cost, namely the installation cost, of the immersed tube tunnel is reduced, and the construction period is shortened.
本发明公开了一种沉管隧道及施工方法，所述沉管隧道由多个筒体收尾对接而成，所述筒体的外形呈圆柱体状；所述筒体包括筒壁、第一肋板、第二肋板、第三肋板、第四肋板和第五肋板；所述第一肋板的两端均连接于所述筒壁的内壁，所述筒体的中轴线位于所述第一肋板所在的平面；本发明提出的沉管隧道的筒体的横截面为圆形，相比传统的横截面呈矩形的沉管，能够在保证筒体的承压能力的同时，尽可能的减小筒体的筒壁的厚度，降低沉管隧道的生产即安装成本，减少施工工期。
