AI Technical Summary
In deep water environments with high tide differences, double-walled steel caissons cannot rely on a constant internal and external head difference to provide buoyancy for vertical positioning. Furthermore, large-sized steel caissons are heavy, and when relying on hanging legs and beams for vertical positioning, the load-bearing capacity requirements are high, the quantity used is large, and the risks are significant.
A double-walled steel caisson structure is designed, which is divided into a bottom section, a middle section, and a top section. The middle section is a hollow, enclosed chamber that provides constant buoyancy. The water level is balanced through connecting holes and a valve system. Vertical positioning is achieved by using hanging legs and hanging beams to ensure the steel caisson is stably positioned in deep water environments with high tide and high tide differences.
It achieves constant buoyancy positioning of steel caissons in deep water environments with high tide differences, reduces weight and leg load-bearing capacity requirements, improves construction safety and flexibility, and simplifies construction operations.
