The bank slope protection on both sides needs to have a buffer structure to prevent damage to the slope protection and ships caused by ship collision. However, the current port channel slope protection structure still has the following problems in use:

[0003] Currently, most port channel slope protection structures use fixed tires or protective baffles equipped with dampers to protect against ship collisions. However, the above protective structures lack a layered buffering system and are unable to weaken the impact force at multiple levels for buffering, resulting in poor overall buffering and energy absorption effects.
