Super speed transportation scheme and construction method of vacuum suspension cross-ocean tunnel

LIU ZIZHONG

The invention discloses a super speed transportation scheme and a construction method of a vacuum suspension cross-ocean tunnel. According to the super speed transportation scheme and a construction method of a vacuum suspension cross-ocean tunnel, the tunnel and a traveling bogie are included. The super speed transportation scheme and the construction method are characterized in that a steel pipe with a large diameter is used as the subsea tunnel, an exhaust fan located at the exit of the tunnel is used for keeping the interior of the tunnel in a relatively vacuum state, and buoyancy force of seawater is sufficiently utilized to enable the tunnel to suspend in the seawater; a cylindrical bogie is adopted to carry persons and materials in the tunnel, and vacuum in front of the bogie is taken as the power of the bogie to achieve the purpose of transportation. The super speed transportation scheme and the construction method of the vacuum suspension cross-ocean tunnel have the beneficial effects that the construction cost is low, environmental disruption is small, the operation and maintenance cost is low, the construction period is short, the transportation speed is high , and application prospects are wide.
