The utility model relates to an immersed tube tunnel transportation by driving construction field in seabed provides a vertical occasional passage of business turn over immersed tube. This occasional passage installs in the below of manhole shaft, at the sink in -process of installation of the tube coupling of immersed tube, still can lead to this occasional passage and realize outside and inside the passing of tube coupling to convenient subsequent construction, on this basis, this occasional passage is firm durable, builds and demolish simple and efficient, can relapse to install and remove many times, in addition, it is small that this occasional passage dismantles the back, be convenient for transportation and storage.
