To use more construction surplus soil to backfill tunnels and pump fluidized soil to casting sites further from a manufacturing plant.SOLUTION: In a tunnel backfilling method, fluidized soil that is pressure-fed to one placing place P1 out of a plurality of placing places is produced by kneading excavated soil, a solidifying material and water in a first composition. The fluidized soil that is pressure-fed to another placement place P2 having a longer pumping distance than one placement place P1 is produced by kneading the excavated soil, the solidification material and water in the second composition, which contains less excavated soil and more water than the first composition.SELECTED DRAWING: Figure 3
【課題】より多くの建設発生土をトンネルの埋戻しに用いると共に、製造プラントからより離れた打設場所へ流動化処理土を圧送する。【解決手段】トンネル埋戻し方法は、複数の打設場所のうち一の打設場所Ｐ１に圧送される流動化処理土を、掘削土、固化材及び水を第１配合で混練して製造し、一の打設場所Ｐ１よりも圧送距離が長い他の打設場所Ｐ２に圧送される流動化処理土を、第１配合に比して掘削土が少なく、水が多い、第２配合で掘削土、固化材及び水を混練して製造する。【選択図】図３
