Self-propelled underwater tunnel immersed tube carrying and mounting integrated ship and construction process

Abstract

The invention discloses a self-propelled underwater tunnel immersed tube carrying and mounting integrated ship. The ship comprises a first ship body and a second ship body which are parallel, a connecting structure is arranged between the first ship body and the second ship body, and traction hoisting equipment arranged on the first ship body, the second ship body and the connecting structure. A carrying space is formed between the first ship body and the second ship body below the connecting structure, a component to be installed is arranged in the carrying space and connected with the ship bodies, and a propelling power device and a power positioning system are arranged on the first ship body and the second ship body. The lower portion of the integrated ship is provided with the carryingspace. Goods to be transported are placed in the carrying space and float in water. Most weight of goods is shared by buoyancy. The goods are transported to the designated position, and precise installation work is completed. Underwater tunnel immersed tubes or similar large components of various sizes can be independently transported and installed through one self-propelled ship body successfully, other ships do not need to be used for dragging, channels do not need to be sealed for other ships in the transportation process, and passing of other ships is not affected.

Description

technical field [0001] The application relates to the technical field of construction engineering of cross-river and sea-crossing tunnels, in particular to a self-propelled underwater tunnel immersed tube carrying and installing integrated ship and construction technology. Background technique [0002] The immersed tube tunnel is to solve the traffic between the straits, bays or rivers, and build underwater buildings for people and vehicles to pass through. Usually, immersed tube tunnels are prefabricated in sections and then transported by water to designated locations for construction and installation. In order to ensure the smooth passage of vehicles inside the immersed tube after the tunnel is completed, the immersed tube is very bulky, and usually the weight of each immersed tube exceeds 10,000 tons. The transportation and installation of such a huge object has become a very important factor that restricts the construction efficiency and construction period of the subma...

Problems solved by technology

The above-mentioned traditional transportation method is slow in transportation speed, it is difficult to coordinate between tugboats, and it is easy to deviate. In addition, the channel needs to be closed during transportation, and other ships are prohibited from passing, which seriously affects shipping traffic.

In addition, the traditional installation method requires the construction of special sinking barges, and two sets of sinking barges are required to realize the fine positioning installation of immersed tubes. When using traditional installation methods, the scheduling arrangement between ships is complicated, the construction period is long, and the operation efficiency is low. Low, high safety risk, high construction cost
