BACKFILLING DEVICE AND BACKFILLING METHOD FOR PIPE

To provide a backfilling device allowing excavated soil to be easily recycled.SOLUTION: A backfilling device (1) is provided with: an excavated soil screening section (10) for passing soil having particle sizes equal to or less than a predetermined size and placeable above an excavation trench; and a gravel storage section (20) for storing, among the excavated soil, gravel not passing through the excavated soil screening section due to its particle size larger than the predetermined size and attachable/detachable to/from the excavated soil screening section.SELECTED DRAWING: Figure 1 【課題】掘削土を容易に再利用可能な埋め戻し装置を実現する。【解決手段】埋め戻し装置（１）は、所定の大きさ以下の粒径である土砂を通過させるとともに、掘削溝の上方に設置可能な掘削土選別部（１０）と、掘削土のうち、掘削土選別部を通過しなかった所定の大きさよりも大きい粒径である礫を収納するものであるとともに、掘削土選別部に対して着脱可能な礫収納部（２０）と、を備えている。【選択図】図１
