Problems solved by technology

The traditional transportation method needs to bind and fix the immersed tube first, reserve multiple towing lifting points, and then equip multiple high-power tugboats to tow the immersed tube for transportation; the channel needs to be closed during transportation, and other ships are prohibited from passing. Seriously affect shipping traffic; the traditional installation method needs to build a special installation ship for fine positioning installation; when using the traditional method of installation, the scheduling arrangement between ships is complicated, the construction period is long, the operation efficiency is low, and the construction cost is high

Abstract

The invention discloses a self-propelled carrying and installing all-in-one ship for underwater tunnel immersed tubes. A first ship body and a second ship body are parallel with each other, connection structures are installed between the first ship body and the second ship body, the first ship body, the second ship body and each the connection structures are each provided with pulling and hoisting equipment, a carrying space is located below the positions, below the connection structures, of the first ship body and the second ship body, a to-be-installed component is installed in the carrying space and connected with the ship bodies, and the first ship body and the second ship body are each provided with a propelling power device and a positioning device. According to the self-propelled carrying and installing all-in-one ship for the underwater tunnel immersed tubes, self-propelled power over long distances is achieved, the underwater tunnel immersed tubes with different sizes can be independently transported without towing of other ships, channel closing for other ships in transportation is not needed, and navigation of other ships is not affected; a double-structure ship has high stability, sink resistance and capsizing resistance; and the pulling and hoisting equipment can accurately locate the immersed tubes, and the function of accurately installing the immersed tubes without the assistance of other ships can be achieved.

Description

technical field [0001] The invention relates to transportation equipment for a cross-river and sea-crossing tunnel construction project, which is suitable for the transportation and installation of immersed pipes or similar components to be installed in cross-river and sea-crossing tunnels. Background technique [0002] Immersed tube tunnel is currently the structural form often used in cross-river and sea-crossing tunnels at home and abroad. After the prefabrication is completed, the immersed tube needs to be transported to the installation site for installation. The traditional transportation method needs to bind and fix the immersed tube first, reserve multiple towing lifting points, and then equip multiple high-power tugboats to tow the immersed tube for transportation; the channel needs to be closed during transportation, and other ships are prohibited from passing. Seriously affect shipping traffic; the traditional installation method needs to build a special installa...
