AI Technical Summary
The existing offshore mixing plants have a single method for supplying sand and gravel, which makes it difficult to ensure an efficient and continuous supply in complex marine environments, resulting in an unstable supply system.
A multi-channel feeding system is adopted, including three feeding methods: grab crane, belt conveyor, and self-unloading dump truck on the trestle channel. Combined with sunken hoppers and berthing piles, it realizes multi-path feeding.
It improves the stability and continuity of the material supply system, enhances its mobility and adaptability, reduces equipment configuration requirements, and ensures the continuous operation of the offshore mixing plant.
