Abstract

PURPOSE:To vertically erect and fix a steel rig on soft or sloped ground by a method in which expandible legs with bottom plates to be driven by an oil-pressure cylinder are provided in plural vertical pipes fixed to the peripheral edges of the base of the steel rig for offshore boring operation in such a way as to enable the legs to be freely moved. CONSTITUTION:A steel rig 1 is settled to the sea bed, an engine or an oil-pressure unit 9 provided on the top 3 of the rig is actuated by operating the switch of a switchboard 10 provided to large 11, and legs 5 are extended or shrunk by driving an oil-pressure cylinder 7 provided in vertical pipes 4 so as to stabilize bottom plates 6 on the ground.

Vertical pipes (a) are supported by several pieces around the periphery of the base and fixed upright.The upper ends of the pipes are closed to make them watertight.A hydraulic cylinder (7) is installed inside each of these pipes with a lower opening.

) A cylinder connected by an oil pipe from a hydraulic unit installed in the turret is operated and driven from the top of the turret, allowing the legs to move freely.However, the legs can be made to any length to accommodate sloping ground, and the turret stands vertically on the ground, eliminating the concerns of the past. A document level adjustment device that eliminates the problem.
