DEVICE FOR CONSTRUCTING SAND PILE
To provide a device for constructing sand pile which can easily penetrate a casing into the hard ground without any vibration and noise and which can compact the ground at a low cost.SOLUTION: A device 1 for constructing sand pile comprises: a casing 10 which constructs a sand pile K without any vibration and noise by penetrating into the ground D while rotating and discharging sand S when the casing is extracted and installing back the sand repeatedly; and a drilling bit 20 which is stretched in a V shape so as to cross a tip opening 10b of the casing 10 and which assists penetration of the casing 10. The drilling bit 20 is formed in a V shape by at least a pair of inclined parts 22 and 22 inclined and intersecting at an apex 21, and each inclined part 22 has a plurality of excavation claw parts 25 for projecting downward and drilling the ground D in the casing 10.SELECTED DRAWING: Figure 1
【課題】無振動・無騒音でケーシングを硬質地盤に容易に貫入させることができ、低コストで地盤を締め固めることができる砂杭造成装置を提供する。【解決手段】砂杭造成装置１は、地盤Ｄ中に回転させながら貫入し、引き抜く際の砂Ｓの排出と打ち戻しを繰り返すことで無振動・無騒音にて砂杭Ｋを造成するケーシング１０と、ケーシング１０の先端開口１０ｂを横切るようにＶ字状に架け渡され、ケーシング１０の貫入を補助する掘削ビット２０と、を備え、掘削ビット２０は、傾斜して頂部２１で交わる少なくとも一対の傾斜部２２，２２によりＶ字状に形成され、各傾斜部２２は、下方に突出してケーシング１０内の地盤Ｄを削る複数の掘削爪部２５を有する。【選択図】図１
