BOX FOR A MARINE STRUCTURE AND CONSTRUCTION METHOD FOR A MARINE STRUCTURE USING THE BOX FOR IMPROVING SAFETY OF A STRUCTURE AND PREVENTING ENVIRONMENTAL POLLUTION PROBLEMS

摘要

PURPOSE: A construction method for a marine structure using a box is provided to reduce the cost and time required for construction, to heighten the stability on a structure by resisting external force such as wave energy after construction, to resolve problems by environmental pollution and to exclude maintenance work after construction. CONSTITUTION: The construction method for a marine structure using a box comprises the steps of: locating a box(100), which has many housing spaces on a body made of positive buoyant materials and setting holes(112) perforated vertically on the remaining part except the housing spaces, on the soft ground; inserting a steel pipe pile(120) into the setting hole(112) of the body to make the lower end of the steel pipe pile(120) supported to the firm ground; fixing a hardener injector(130) provided with injection holes(131) to an inlet of the setting hole(112) to inject liquefied hardener; descending the box(100) to the appointed depth; filling up the steel pipe pile(120) with hardener by injecting liquefied hardener through the injection hole(131) of the hardener injector(130) from the outside; and filling up the housing spaces of the box(100) with weights.
