AI Technical Summary
Under conditions of ultra-deep water and high flow velocity, the positioning accuracy of ultra-large caissons is poor, the cable condition is unstable, the hoisting and connection operation is difficult, and the positioning of the cable is difficult. Existing positioning and cable-passing construction methods cannot meet the accurate positioning requirements of ultra-large caissons.
The floating platform is positioned and cable-laying is carried out using a floating structure positioning and cable-laying method. Multiple gravity anchors are used to connect the platform to the floating platform. Anchor boats and tugboats work together to connect the anchor cables in a specific sequence and use winches to pull them, so as to achieve precise positioning of the floating platform and cable connection.
It achieves efficient and accurate caisson positioning for ultra-large caissons, reduces engineering workload and costs, improves positioning accuracy and cable stability, and simplifies the cable laying process.
