PURPOSE: To raise durability of a ship buffering work by avoiding the exposure of constituents to sea water for the ship buffering work to prevent damage to the main tower base by collision of ships by providing it for the surrounding of the main tower base to support the main tower of suspension bridge and skew bridge.

CONSTITUTION: In a buffering work 10 to be attached to surroundings of a main tower base, steel tubes are arranged vertically and horizontally by biasing the heightwise and widthwise directions of the tubes into a well-cribbed form to form a framework. The periphery of the framework is covered with a concrete wall 19. The framework is attached to the surrounding of the main tower base 2 through fitting parts 16 to prevent the intrusion of sea water into the buffering work, and the corrosion of the constituents by sea water can also be prevented. The impact energy-absorbing function of the buffering work can thus be stably kept for long periods.
