Abstract
Description
Technical Field
[0001] This utility model belongs to the field of underwater pipeline construction technology, specifically relating to an underwater pipeline installation device. Background Technology
[0002] With the increasing demand for water conservancy projects in recent years, China has made significant progress in the field of water intake head construction technology. Among these advancements, optimizing underwater installation technology has become a major research direction. In underwater pipeline installation, my country has adopted advanced technologies including floating crane lifting, diver-assisted installation, and remotely operated underwater vehicles (ROVs). The application of these technologies has greatly improved the accuracy and efficiency of construction. In particular, underwater splicing and installation technology for large-diameter pipelines has received in-depth research and development in recent years.
[0003] Of particular note is that in "integrating fragmented" lifting operations, by further refining the lifting plan, equipment such as floating cranes and pontoons can be used to achieve the overall lifting and docking of large sections of pipeline. This method not only significantly reduces the steps required for multiple partial assemblies but also effectively reduces the risks and accumulated errors from each operation. However, many current installation equipment, such as pontoons, are insufficient in adapting to pipelines of different diameters, leading to the need for different specialized equipment for different diameters, thus complicating equipment management and increasing costs. Therefore, developing an installation solution that can flexibly adapt to multiple pipeline diameters has become key to improving overall work efficiency and reducing project costs.
