EXCAVATION BUCKET AND METHOD FOR CONSTRUCTING CAST-IN-PLACE PILE
To provide excavation buckets that can ensure the verticality of pile holes even when there are hard parts in the ground.SOLUTION: An excavation bucket 1 is attached to an excavator that excavates the ground to form a pile hole. The excavation bucket 1 includes a cylindrical trunk portion 20 that can be attached to a lower end of a kelly-bar 14 of the excavator, and a bottom plate 30 that closes an opening on a bottom surface of the trunk portion 20 and is provided with an excavation bit 32. A plurality of blades 40A to 40I are spirally provided on an outer peripheral surface of the trunk portion 20.SELECTED DRAWING: Figure 1
【課題】地中に硬い部分があっても、杭孔の鉛直性を確保できる掘削バケットを提供すること。【解決手段】掘削バケット１は、地盤を削孔して杭孔を形成する掘削機に取り付けられる。この掘削バケット１は、掘削機のケリーバ１４の下端に装着可能な円筒形状の胴部２０と、胴部２０の底面の開口を閉塞しかつ掘削ビット３２が設けられた底盤３０と、を備え、胴部２０の外周面には、複数のブレード４０Ａ〜４０Ｉが螺旋状に設けられている。【選択図】図１
