Measures and methods for extending the lifespan of fishing port facilities.
The method of "belly support construction" using underwater concrete, which incorporates precast residual formwork as part of the structure.
<Ensuring Safety and Planning> ■ The residual formwork method allows for construction in stages, eliminating enclosure and enabling quick evacuation actions in emergencies. ■ The residual formwork itself is self-supporting, making it possible to work safely underwater. ■ It is possible to ensure planning for offshore construction, which is easily affected by weather and sea conditions. <Economic Efficiency and Improved Workability> ■ The absence of enclosed spaces improves work efficiency, leading to a reduction in construction time. ■ The lightweight of the products allows for construction using small machinery. ■ In conventional methods, a minimum width of 1.0 m was often required for underwater working space, leading to designs based on stability calculations that exceeded this width. However, with the residual formwork method that does not require enclosed spaces, designs can be made according to stability calculations, reducing the amount of concrete needed. <Simplification of Material Procurement> ■ Due to staged construction, securing ready-mixed concrete is easy and workability is good, allowing for small-scale placements in fishing port construction. ■ Material delivery is limited to the staged construction, reducing yard area and simplifying yard planning.
