DRILLING MACHINE USED IN PILE FOUNDATION WORKS
To provide a low noise drilling machine used in pile foundation works that after making a hole with a small diameter screw, gradually changes the same to large diameter screws and can finally complete a desired diameter pile hole.SOLUTION: A drilling machine for pile foundation works comprises a screw 5 including a first spiral piece, a second spiral piece, and a third spiral piece, and is designed for reducing a noise in drilling . The drilling machine makes a hole with the screw 5 having a small diameter first, and then makes a hole diameter larger by increasing the number of mounted spiral pieces and gradually enlarges the hole diameter, and finally finishes the drilling with the hole diameter having a desired diameter. The first spiral piece is fixed to a shaft 4, and the second spiral piece and the third spiral piece have annular spiral structures. Since their weight is lighter than that of the conventional screws 5 with the same drilling effect, a transportation cost when transporting a plurality of the screws 5 can be greatly reduced.SELECTED DRAWING: Figure 1
【課題】直径の小さいスクリューで穴を開けた後、徐々に直径が大きいスクリューに変えていき、最終的に、所望の直径の杭穴を完成させることができる、杭基礎工事に用いる低騒音の掘削装置を提供する。【解決手段】杭基礎工事の掘削装置は、第１螺旋片、第２螺旋片、第３螺旋片のスクリュー５からなり、掘削時の騒音を低減するために設計されている。まず直径の小さいスクリュー５で穴をあけ、その後、取り付ける螺旋片を増やすことで、穴径を増大させて、徐々に穴径を拡大し、最終的に所望の直径の穴径の掘削を完成させる。第１螺旋片がシャフト４に固定され、第２螺旋片と第３螺旋片は、環状螺旋構造であり、重さは、従来の同等の掘削効果を有するスクリュー５に比べて軽く、複数のスクリュー５を運ぶ際の輸送コストを大幅に低減できる。【選択図】図１
