REMOVAL METHOD FOR CONSTRUCTION GIRDER, AND EARTH-RETAINING PLATE FOR REMOVAL OF CONSTRUCTION GIRDER
PROBLEM TO BE SOLVED: To reduce pull-up resistance and suppress an influence on ballast, in removal of a construction girder 10 for temporarily retaining a rail 1 via substitutional sleepers 12 and 13 during construction of an underground structure under a track.SOLUTION: In removal of a construction girder 10, substitutional sleepers 12 and 13 are first removed (c). Next, a lid-like earth-retaining plate 20 is attached to a side part of the construction girder 10 of an I-shaped cross-section (d). Subsequently, ballast 15 is backfilled below a rail 1, and a sleeper 16 is installed on the ballast 15 to rehabilitate the rail 1 (e). After that, the construction girder 10 is hoisted and removed.SELECTED DRAWING: Figure 5
【課題】 軌道下での地下構造物の構築中に代替枕木１２、１３を介してレール１を仮受けする工事桁１０の撤去に際し、引き上げ抵抗を減少させると共に、バラストへの影響を抑える。【解決手段】 工事桁１０の撤去に際しては、先ず、代替枕木１２、１３を撤去する（ｃ）。次に、Ｉ型断面の工事桁１０の側部に、蓋状の土留板２０を取付ける（ｄ）。次に、レール１の下方にバラスト１５を埋め戻し、バラスト１５上に枕木１６を設置することで、レール１を復旧する（ｅ）。この後、工事桁１０を吊り上げて撤去する。【選択図】 図５
