Loading device and loading method for seabed corridor under soft geology

The seabed corridor loading device under the soft geology comprises loading bins, a collecting ditch and a control unit, each loading bin is provided with a plurality of unit bins in a layered mode through a grating framework, and an electromagnetic spring is arranged in each unit bin and used for adjusting the height of the unit bin; the loading method comprises the steps of determining a loading scheme, adjusting an electromagnetic spring, pumping a mud-water mixture to form temporary loading, monitoring a sinking process, draining and consolidating to form permanent loading and paving a road surface. A force transducer and an attitude sensor are used for continuous monitoring in the whole corridor sinking process, the construction stability is ensured, after the corridor sinks into the seabed, water in a mud-water mixture is drained layer by layer in a drainage consolidation mode, and solid particles are left to provide permanent loading for the corridor. According to the method, the stress and stable stat
