Mobile high-precision underwater layered hydraulic reclamation control construction method

The invention belongs to the technical field of dredging hydraulic reclamation construction, and particularly relates to a movable high-precision underwater layered hydraulic reclamation control construction method. Comprising the following steps: step 1, construction preparation; step 2, layered hydraulic reclamation; and step 3, ending construction. The movable high-precision underwater layered hydraulic reclamation equipment suitable for the construction method is characterized by comprising a floating platform, a slurry conveying pipeline, a movable positioning winch, a layered hydraulic reclamation module, a monitoring module and a control module. On the basis of monitoring and analyzing environmental conditions such as construction water depth, water flow and waves, high-precision control over the thickness and flatness of a sedimentary layer is achieved by dynamically adjusting parameters such as the hydraulic reclamation flow speed, concentration, lowering depth and moving speed, the continuous operat
