Description

Technical Field

[0001] This invention relates to a docking device for a barrel foundation and a negative pressure sinking device. Background Technology

[0002] In recent years, my country's offshore wind power projects have developed rapidly. However, the hydrological and geological conditions of wind farms are becoming increasingly harsh and complex, making the construction of offshore wind power projects using traditional monopile and high-pile cap structures increasingly difficult and costly. Bucket foundations, as a type of non-driven shallow foundation, have a large diameter and small height. They typically use negative pressure sinking equipment to achieve suction-force sinking, which is relatively economical in terms of engineering exploration costs and steel consumption. However, offshore bucket foundations are currently less common, and due to the extremely harsh working conditions during construction, their reliability and maintenance costs are high. Currently, the main installation method for negative pressure sinking equipment, both domestically and internationally, involves welding four right-angled plates with sloped upper sections to corresponding positions on the top surface of the bucket foundation. The negative pressure sinking equipment is then positioned and installed along these right-angled plates. This installation method is overly simplistic, requires manual intervention, has low positioning accuracy, poor guiding effect of the right-angled plates, and is inefficient. Summary of the Invention

[0003] The purpose of this invention is to overcome the existing defects and provide a docking device for barrel foundations and negative pressure sinking equipment. It enables rapid installation and recovery of negative pressure sinking equipment, and significantly shortens the offshore construction cycle of barrel foundations.
