DIAMETER EXPANSION DEVICE AND DIAMETER EXPANSION METHOD
To provide a diameter expansion device capable of accurately and efficiently expanding a diameter of a drilling hole formed for an underground continuous wall with a simple constitution.SOLUTION: A diameter expansion device 1 for expanding a diameter of a drilling hole for forming an underground continuous wall includes: a reamer 2 which forms an expanded diameter hole larger than a width in a traverse direction of the drilling hole by rotation; a guide 10 which is mounted above the reamer and is formed so as to be slid while being brought into contact with the expanded diameter hole; and a bucket 20 which is mounted below the reamer, is formed so that the width in the longitudinal direction is larger than a diameter of the expanded diameter hole and is formed so that the traverse direction is slid while being brought into contact in the traverse direction of the drilling hole.SELECTED DRAWING: Figure 1
【課題】簡便な構成により地中連続壁のために形成された掘削孔を正確かつ効率的に拡径することができる拡径装置を提供する。【解決手段】地中連続壁を形成するための掘削孔を拡径するための拡径装置１であって、掘削孔の短手方向の幅よりも大きい径の拡径孔を回転して形成するリーマー２と、リーマーの上方に取り付けられ、拡径孔に当接しながら摺動するよう形成されたガイド１０と、リーマーの下方に取り付けられ、長手方向の幅が拡径孔の径よりも大きく形成されると共に、短手方向が掘削孔の短手方向に当接しながら摺動するよう形成されたバケット２０と、を備えることを特徴とする拡径装置である。【選択図】図１
