In the technical field of dredging construction, sand is generally mined by adopting a sand mining construction process, and a sand source obtained by sand mining construction is subjected to land reclamation construction to form land. The sand source obtained by sand mining construction usually contains large soil and stone impurities, and on the other hand, dredging impurities such as stones, hard clay and the like dumped by earlier construction units are distributed on the surface of the covering layer of the sand mining area to different degrees, and part of the dredging impurities sink and are embedded into a sludge layer, so that the collected sand source cannot meet the requirements of project construction on the quality of the sand source, screening treatment is needed, and the large-particle impurities in the sand source are filtered to obtain a qualified sand source for land reclamation. Furthermore, construction of a project usually requires a certain mud content of the sand source, and therefore the obtained mud usually needs to be washed to remove the excess mud.

The collected sand source is generally transported by a sand barge, which is a ship for transporting the sand source to and from a sand mining construction water area, and the sand barge receives the sand source and transports the sand source to the shore or drives into a reclamation area. Specifically, a loading and refuting platform is arranged in a construction water area, a sand barge is stopped at the side position of the loading and refuting platform and receives sand loaded on the loading and refuting platform, the sand barge is driven away from the loading and refuting platform after being filled with the sand, and the sand barge is driven to the bank side and then is discharged with the sand. Therefore, the sand barge is used as an important transportation facility in sand production construction, and plays an important role in the whole sand production construction.

Existing sand barges typically consist of a vessel and sand tanks into which slurry containing a sand source is delivered by a dredge pump and associated piping or by a loading platform, after which the sand barge carries the sand source to land or a reclamation area for unloading. Unlike conventional sand barges that transport dry sand, sand barges used in the aforementioned applications carry a high moisture content source of sand, depending on the environment in which it is operated and the manner in which it is stowed. During the process of loading the sand barge by the mud pump and the related pipeline and loading platform, the mud and the sand source are loaded together, and the loading operation of the sand barge is normally carried out in an overflow loading mode, specifically, the mud on the upper layer is discharged from the top edge of the sand cabin in an overflow mode by continuously loading the sand cabin.

The sand barge described above has the following problems: the sand source subsides in the in-process of carrying, adopts the artifical mode that gets into the sand cabin and unload the sand behind the bank or adopts auxiliary machinery (like the grab bucket machine) etc. to unload the mode of sand and have the problem that unload sand inefficiency, waste time and energy etc. lead to the transport and the availability factor of sand source to receive the influence.
