Underwater suspension tunnel
The invention provides an underwater suspension tunnel. The underwater suspension tunnel comprises a tunnel body, a cable anchor device and a buoyancy-weight ratio self-adjusting device, wherein the tunnel body comprises a shell and a cavity; the shell is used for isolating the cavity from water flow, and the cavity is used for passing; the cable anchor device is used for connecting the tunnel body with a river bank stratum so as to provide anchoring force for the tunnel body; and the buoyancy-weight ratio self-adjusting device is used for automatically adjusting the form of the tunnel body in water according to the water flow speed and the operation load condition in the tunnel body and controlling the water flow speed of the upper surface and the lower surface of the outer side of the tunnel body, and therefore the purpose of controlling the buoyancy-weight ratio of the tunnel body is achieved. According to the underwater suspension tunnel, buoyancy can be automatically adjusted according to the water flow condition and the traffic load condition in the tunnel, the structural stress of the tunnel structure is more reasonable, meanwhile, the stress of a suspension cable, a pull rod and other structures can be reduced through buoyancy generated by water flow, the long-term service performance of the tunnel structure is facilitated, and high economic benefits are achieved.
本发明提供一种水下悬浮隧道，包括隧道主体、索锚装置和浮重比自调节装置；所述隧道主体包括外壳和空腔，所述外壳用于将空腔与水流进行隔离，所述空腔用于通行；所述索锚装置用于将隧道主体与河岸地层连接，以为隧道主体提供锚固力；所述浮重比自调节装置用于根据水流流速及隧道主体内的运营荷载情况自动调整隧道主体在水中的形态以及通过控制隧道主体外侧上表面和下表面的水流流速，从而达到控制隧道主体浮重比的目的。本发明能够根据水流情况及隧道内交通荷载情况实现浮力的自动调整，不仅使得隧道结构的结构受力更加合理，同时可以利用水流产生的浮力降低悬索、拉杆等结构的受力，有利于隧道结构的长期服役性，具有较高的经济效益。
