Gabion throwing damming construction method

The invention relates to the technical field of underwater damming construction, and particularly discloses a gabion throwing damming construction method which comprises the following steps: dividing a construction water area into a plurality of construction area grid areas, and obtaining the throwing amount of each grid area according to the area and the throwing height of each construction area grid area. And a stone cage to be thrown is placed on the transport ship. The transport ship and the positioning installation ship are positioned and driven to the construction position of the first construction area grid area, the construction area grid area is filled with a corresponding amount of stone cages through a crane according to the throwing amount, and meanwhile the drifting distance generated by the effect of water flow in the stone cage throwing process is calculated according to the surface flow speed of the water flow and the water depth; and the real-time throwing position of the positioning installa
