RAILWAY BRIDGE REHABITATION METHOD USING SUPERSTRUCTURE CONTINUATION SUPPORT TRASITION AND PIER REPLACEMENT

摘要

The present invention is a method of continuation of the discontinuous superstructure of a railway bridge composed of a continuous simple span and replacing the pier, comprising: a first step of installing a bracket supporting the adjacent discontinuous superstructure on the upper part of the pier for replacement; a second step of temporarily supporting the discontinuous superstructure by removing the reinforcement at an existing point of the discontinuous superstructure, and moving both supports on the bracket to be spaced apart; A third step of installing a new pier and a new support on the upper part of the new pier; And it relates to a railway bridge reinforcement construction method using the continuation of the bridge superstructure, point movement and pier replacement, characterized in that it comprises a fourth step of sequencing the adjacent discontinuous superstructure and removing the pier for replacement.
