<p>PROBLEM TO BE SOLVED: To provide a method for reconstructing a steel tower, in a relatively short term for work, without requiring a new construction site or a large leased land for work. SOLUTION: A base construction (reaction cross-beams 1 and load beams 2) is assembled from an established steel tower 8 to a removing position (temporarily fixing site) in a direction of the line, and a rail 3 is fixed thereon. A leg part of the steel tower 8 is fixed to a pair of front and rear removing axles 4 to be slid on the rail 3 and put in a movable state. Strung wire is set movable by a metallic wheel with respect to a steel tower. After moving, the established steel tower 8 is fixed to the base construction and used as a temporally constructed tower. A new steel tower is constructed to the original site of the steel tower 8, and the strung wire is moved to the new steel tower. Then, the steel tower 8, the remaining rail, and the base construction are removed.</p> |
