【課題を解決するための手段】
本発明の請求項１記載の杭圧入装置は、杭を地盤に圧入するに際し、ケーシング付きアースオーガで杭を圧入する部分を掘削して杭を圧入するものであり、上記杭を掴むチャックと、該チャックを昇降させることにより杭の圧入を可能とする杭昇降手段とを備え、かつ、上記チャックに、上記アースオーガのケーシングを掴むケーシングチャックが備えられ、さらに、上記チャックとは別の位置に、上記ケーシングチャックに掴まれるケーシングを掴んで支持するケーシング支持部が設けられていることを特徴とする。
上記構成によれば、アースオーガのケーシングを掴んだケーシングチャックを備えるチャックの杭昇降手段による上昇と、ケーシングチャックからケーシングを放し、かつ、ケーシング支持手段でケーシングを掴んで支持した状態での杭昇降手段の下降による元の位置への復帰とを繰り返すことで、クレーンを使わずにアースオーガを引き抜くことができる。

[Means for solving problems]
The pile press-fitting device according to claim 1 of the present invention excavates a portion where the pile is press-fitted with an earth auger with a casing and press-fits the pile when the pile is press-fitted into the ground. and a pile lifting unit for enabling press-pile by lifting the chuck and, in the chuck, casing chucking click grab casing of the earth auger are provided, further, a position different from the above chuck It is characterized in that a casing support portion for gripping and supporting the casing gripped by the casing chuck is provided.
According to the above configuration, the pile elevating means of the chuck provided with the casing chuck holding the casing of the earth auger and the pile raising / lowering in a state where the casing is released from the casing chuck and the casing is gripped and supported by the casing supporting means. By repeating returning to the original position by lowering the means, the earth auger can be pulled out without using a stake.
本発明の請求項２記載の杭圧入装置は、上記ケーシング支持部が、上記ケーシングを掴む支持チャックと、該支持チャックを昇降する支持チャック昇降手段とを備えていることを特徴とする。
上記構成によれば、杭昇降手段を復帰させる際に、ケーシング支持部の支持チャックでケーシングを掴んでアースオーガを支持するとともに、支持チャックを支持チャック昇降手段で上昇させることにより、杭昇降手段の復帰中もアースオーガを引き上げることができるので、ほぼ連続してアースオーガを引き上げることができ、ケーシングの引抜時間をさらに短縮することができる。
The pile press-fitting device according to claim 2 of the present invention is characterized in that the casing support portion includes a support chuck for gripping the casing and a support chuck elevating means for raising and lowering the support chuck.
According to the above arrangement, when returning the pile lifting unit, while supporting the grounding auger grabbing casing supporting chuck casing support portion, Ri by the raising of the support chuck in support chuck lifting means, pile lifting Since the earth auger can be pulled up even during the return of the means, the earth auger can be pulled up almost continuously, and the pull-out time of the casing can be further shortened.
Claims (1)
