    TECHNICAL FIELD
  • The present invention relates to a transportation equipment of cross-river and cross-ocean tunnel construction engineering and is applicable to transportation and installation of immersed tubes of cross-river and cross-ocean tunnels or similar to-be-installed members.
    • BACKGROUND OF THE INVENTION
  • At present, the immersed tunnel is a structural form usually adopted by cross-river and cross-ocean tunnels at home and abroad. After prefabrication, immersed tubes need to be transported to an installation site for installation. The traditional transportation method is realized by binding and fixing the immersed tube first, reserving a plurality of hauling and hoisting points and then equipping with a plurality of high-power towing ships to haul the immersed tube. During the transportation, the navigation lane needs to be closed, and other ships are prohibited from passing, which seriously affects the shipping traffic. Also, the traditional installation method cannot locate and install precisely without building a special installing ship. When the traditional installation method is adopted, the organizing of the marine activities is complicated and difficult, the construction period is long, the working efficiency is low and the construction cost is high.

  • In order to solve the aforementioned technical problems, the present invention is realized via the technical solutions as follows.
  • A self-propelled integrated ship for transporting and installing immersed tubes of underwater tunnel, comprising a first ship body, a second ship body, a connection structure, hauling and hoisting devices, propelling power devices and positioning devices; the first ship body and the second ship body are parallel with each other, the connection structure is arranged between the first ship body and the second ship body, the first ship body, the second ship body and the connection structure are provided with the hauling and hoisting devices; a loading space is formed between the first ship body and the second ship body and below the connection structure, a to-be-installed member is arranged in the loading space and is connected with the ship; and the first ship body and the second ship body are provided with the propelling power devices and the locating devices.
  • Furthermore, the connection structure stretch across surfaces of the first ship body and the second ship body, and there is no less than one connection structure; when there is more than one connection structure, connection structures are distributed symmetrically about a longitudinal center line of the ship.
  • Furthermore, the hauling and hoisting devices are winches and cranes; all the winches and the cranes are symmetrically arranged on the ship bodies and the connection structures to keep the catamaran structure stable; working radii of the cranes cover above the ship bodies and the to-be-installed member, and the working radii are disjoint with each other.
  • Furthermore, the to-be-installed member is an immersed tube.
  • Furthermore, the propelling power devices are respectively arranged at sterns of the first ship body and the second ship body.
  • Furthermore, the positioning devices are positioning anchors and windlasses; and the positioning anchors and the windlasses are respectively arranged at bows or sterns of the first ship body and the second ship body.
  • Compared with the prior art, the present invention has the beneficial effects that:
    • the ship has self-propelled power for a long distance, can independently transport the immersed tube of underwater tunnel or similar to-be-installed members of various sizes without being hauled by other ships, and there is no need to close navigation lanes to other ships during the transportation, thus not affecting the passage of the other ships. The catamaran type ship has a higher stability, and anti-sinking and anti-capsizing capabilities. Through the hauling and hoisting devices, positions of the immersed tube or similar to-be-installed member can be located precisely, and the immersed tube or similar to-be-installed member can be installed precisely by using hauling and hoisting devices cooperatively without assistance of other ships.
