REMOVAL METHOD OF EXISTING PILE
To prevent debris from falling into edge-cut holes around existing piles when cutting the existing piles, and smoothly improve muddy water in the holes after removing the existing piles to the same level as the surrounding ground.SOLUTION: In removing an existing pile 32, which has been cut off from the ground G, by pulling it up by a predetermined length, and cutting and removing the same, large debris (concrete debris) generated during cutting is received by a debris fall prevention plate 40 and a net 46 arranged thereon, so that the debris is prevented from falling into an edge-cut hole 34. It is advantageous in smoothly performing the work of improving the muddy water in the hole 34 after removing the existing pile 32 to the same level as the surrounding ground G.SELECTED DRAWING: Figure 4
【課題】既存杭の切断時におけるがれきの既存杭の周囲の縁切りした孔内への落下を阻止し、既存杭を撤去した後の孔内の泥水を、周囲の地盤と同等に改良する作業を円滑に行なう。【解決手段】地盤Ｇと縁切れされた既存杭３２を所定の長さ毎に引き上げては切断して撤去するにあたって、切断時に発生する大きながれき（コンクリート破片）が、がれき落下防止板４０およびその上に配置されたネット４６により受け止められるため、がれきが縁切りした孔３４内に落下することが防止される。既存杭３２を撤去した後の孔３４内の泥水を、周囲の地盤Ｇと同等に改良する作業を円滑に行なう上で有利となる。【選択図】図４
