| Zusammenfassung: | To shorten a construction period of lining concrete of a tunnel.SOLUTION: In order to form lining concrete of a tunnel, a form consisting of a plurality of form members is assembled on a supporting device of an arch center. After carrying a preform 74 and an end form member 712 into the tunnel by a track TR, a top form 71 is assembled with the preform 74 and the end form member 712 on the track TR, and the top form 71 is moved onto the supporting device 12. This eliminates the need to unload the form members into a temporary storage area and move them from the temporary storage area to an assembly/disassembly area, shortening a construction period.SELECTED DRAWING: Figure 14
【課題】トンネルの覆工コンクリートの工期を短縮化すること。【解決手段】トンネルの覆工コンクリートを成形するために、セントルの支持装置上に、複数のフォーム部材よりなるフォームが組立てられる。プレフォーム７４及び端部フォーム部材７１２をトラックＴＲによって前記トンネル内に搬入した後に、そのトラックＴＲ上においてプレフォーム７４と端部フォーム部材７１２によって天フォーム７１を組立て、その天フォーム７１を支持装置１２上に移動させる。これによって、フォーム部材の仮置エリアへの荷降ろしや、仮置エリアから組・分解エリアへの移動が不要になって、工期を短縮できる。【選択図】図１４ |
