Construction device and construction method for deepwater gravel foundation bed
The invention belongs to the technical field of seabed foundation bed laying, and discloses a construction device and a construction method for a deepwater gravel foundation bed. The device comprises a leveling ship, wherein supporting legs, a gravel throwing tube and a GPS (global positioning system) positioning unit are arranged on the leveling ship; the supporting legs can be withdrawn or extended to a position below the leveling ship, and are used for supporting and fixing the leveling ship; one end of the gravel throwing tube is connected with a material supply ship through a belt conveyor, and the other end of the gravel throwing tube extends to a position below the leveling ship and is used for feeding gravels on the material supply ship into a water bottom; the gravel throwing tube can ascend, descend or horizontally move relative to the leveling ship; the GPS positioning unit is used for positioning the leveling ship. According to the construction device disclosed by the invention, the supporting legs are arranged for lifting the ship body of the leveling ship off the water surface, so that the interferences of waves to the ship height are completely removed, the height of a gravel throwing tube opening is enabled to be controlled, and the high-efficiency and high-precision laying of the foundation bed are guaranteed.
