COMPACTION METHOD FOR BACKFILL SAND
To provide a compaction method for backfill sand capable of sufficiently ensuring a predetermined degree of compaction of backfill sand.SOLUTION: A compaction method for backfill sand involves pouring backfill sand into an excavated portion of a roadbed, inserting a rod-shaped vibrator into the backfill sand layer and applying vibrations to the backfill sand layer while adding water, and moving the vibrator up and down in a depth direction of the backfill sand layer to compact it.SELECTED DRAWING: Figure 1
【課題】埋戻し砂の所定の締固め度を十分に確保できる埋戻し砂の締固め方法を提供する。【解決手段】路盤の掘削部に埋戻し砂を投入し、前記埋戻し砂の層に棒状のバイブレーターを差し込んで注水しながら前記埋戻し砂の層に振動を加え、かつ、前記バイブレーターを前記埋戻し砂の層の深さ方向に上下動させて締め固めを行う、埋戻し砂の締固め方法。【選択図】図１
