Abstract
The present application discloses an integrated immersed tube section and an installation method thereof, and an installation and closure method of immersed tube sections, wherein the integrated immersed tube section includes a standard immersed tube section; and closed annular telescopic water stop joints are arranged at two ends of the standard immersed tube section. By the adoption of the integrated immersed tube section of the present application, a finally closed immersed tube section is still the standard immersed tube section, and a foundation which is the same as that for common tube sections is used, namely the foundation for the finally closed immersed tube section and the foundation for other immersed tube sections do not have a rigidity difference, so that the risk of the non-uniform settlement of the tube sections during operation of the subsea tunnel is effectively reduced; and in addition, the finally closed immersed tube section and other immersed tube sections are installed with the same installation equipment, and no extra equipment such as a floating crane is needed. Compared with an existing method, the methods have the advantages of eliminating installation of …
