Floating tunnel shore connecting system, floating tunnel, and floating tunnel construction method thereof

Abstract

A floating tunnel shore connecting system, a floating tunnel and a floating tunnel construction method are disclosed, where the design method of the floating tunnel is to apply axial tension along one end or two ends of a tube body respectively; The floating tunnel shore connecting system comprises a joint section located at the end of the tube body, which can move along the axial direction and is connected with a tension device for applying axial tension; The floating tunnel comprises a tube body and a hollow cavity, wherein the tube body comprises a floating section and a shore connecting system at two ends, and both joint sections are provided with tension devices. The design method and structure of the floating tunnel provided by the present invention, by applying the axial tension of the tube body, can significantly increase the horizontal stiffness and vertical stiffness of the whole floating tunnel tube body, improving the natural vibration frequency of the tube body, and the safety and reliability of the floating tunnel are improved; It is beneficial to the long-term use of the cable and the foundation anchored on the seabed or the riverbed. The construction risk is also lower, and the cost is also lower, which effectively saves the construction cost, and is easy to implement and popularize the project.
