| Abstract: |
Since we have laid enough railway network, there are only a few new construction projects of railway structures, and we mainly do improvement projects. In railway improvement projects, we generally dismantle old structures and construct new ones. However, in order to reduce CO2 emissions as much as possible, it is necessary to re-use existing structures the utmost. East Japan Railway Company has been carrying out many railway improvement projects, and plans to re-use the existing structures as much as possible. We have devised a construction method that re-uses the slabs and beams of the existing reinforced concrete rigid frame viaducts and remake only the columns, and have used this method in several projects. We have been able to reduce a large amount of CO2 emissions by this method. |
