Background

A leveler is a seabed laying apparatus that lays stones on a seabed by moving a hopper to level the seabed. Traditional jack-up evener mainly combines to form by jack-up drilling platform and leveling mechanism, and jack-up drilling platform plays lift and supporting role, and leveling mechanism then is used for laying the building stones. Wherein the jack-up rig is comprised of a superstructure and legs. The upper structure is a moon pool type barge-shaped floating body with extremely high buoyancy, and the moon pool type barge-shaped floating body can lift along the pile legs so as to adapt to the operation requirements of different water depth conditions. When the leveling machine is standing, the pile legs descend and are inserted into the seabed, the upper structure is jacked up by the lifting mechanism and is separated from the sea surface, and the leveling mechanism can perform stable operation on the top surface of the platform and is not influenced by water surface waves.
