Abstract

The invention relates to a variable-buoyancy buoyancy tank and application thereof. The variable-buoyancy buoyancy tank comprises a shell, exhaust valves and water inlet valves, and is provided with a first main bin, two first water pressure bins and two second water pressure bins, and the buoyancy of the buoyancy tank is adjusted through the exhaust valves and the water inlet valves; and the variable-buoyancy buoyancy tank can be utilized for completing splicing and sinking of long-distance pipelines. According to the variable-buoyancy buoyancy tank and application thereof, the buoyancy magnitude can be controlled in real time, and the variable-buoyancy buoyancy tank is multifunctional and particularly suitable for construction of pipelines in water conservancy projects; and by adoption of a pipeline sinking method, the construction process is simple, the safety performance is high, required ships are few, the adjustability is high, and control is convenient.

Description

technical field [0001] The invention relates to the technical field of buoyancy tanks and pipeline sinking, in particular to a buoyancy-variable buoyancy tank and its application. Background technique [0002] With the development of science and technology and the improvement of people's living standards, more and more projects are being built to benefit the people, which greatly promotes economic development and facilitates people's lives. In the existing technology, the overall construction plan and process system design plan of the cross-river pipeline must ensure the piling control accuracy during the construction process, the installation accuracy of underwater steel structures, and the overall sinking accuracy of the pipeline. The laying of the Hanoi water pipeline is especially The construction of large-diameter and long-distance water pipelines consumes a lot of manpower, material resources, and financial resources, and it is necessary to ensure that nothing goes wro...
