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.
In order to achieve the purpose and effect of sand production, sand production facilities are needed to be configured for sand production engineering, and the sand production facilities generally comprise sand suction/production vessels. The working principle of the sand suction/extraction ship is as follows: the sand suction/extraction ship vertically lowers the end of the suction pipe and inserts the suction pipe into the surface layer of sandy soil, water is sucked by a centrifugal pump, the pressurized sand is sprayed by a nozzle to wash the undisturbed soil, and then mortar is sucked into a sand cabin by a suction pump. As described above, the sucked sand source needs to be filtered and sieved due to the inclusion of a large amount of impurities such as stones, and also needs to be washed with sand due to the high sludge content.
On the other hand, the sand suction/sampling boat has a fixed-point sand sampling characteristic, and needs to be transferred to another water area for sand sampling construction after the sand sampling construction of one water area is completed, so that the sand sampling efficiency is low, and a sand source at the bottom of the water cannot be fully sampled, namely, the sand source is wasted. Therefore, the cutter suction dredger equipment with stronger sand taking capacity and continuous construction operation capacity is gradually applied to sand extraction work engineering, but the sand source collected by the cutter suction dredger also has the problems of high impurity content, high mud content and the like, and the screening and sand washing operation is also needed. In order to improve the sand mining operation efficiency and the matching effectiveness among equipment in dredging construction engineering, a platform type facility which has strong universality and self screening and sand washing functions needs to be developed and designed, and the facility does not exist in the prior art, so that the sand mining efficiency is low, and the construction cost is increased.
