SAND PILE CONSTRUCTION CASING
To provide a sand pile construction casing capable of reducing the cost of overall construction and environmental load by reducing heaving soil and residual soil generated during construction, by reducing the use of filling material sand.SOLUTION: A sand pile construction casing 10 has a casing body 11 that penetrates the ground D while rotating and is used when creating a sand pile K by compacting without vibration or noise by repeating discharge and driving back of the pile material S when pulling it out. The casing body 11 includes an excavation/compaction unit 20 that spans radially across a tip opening for excavating and compacting the soil D. The excavation/compaction unit 20 has an excavation part that excavates the ground D in the forward rotation direction of the casing body 11 and a compaction surface that compacts the ground in the reverse rotation direction of the casing body 11.SELECTED DRAWING: Figure 1
【課題】施工時に発生する盛上がり土や残土を減らし、かつ、中詰めの材料砂の使用を削減することで、施工全体の低コスト化及び環境負荷の低減を図ることができる砂杭造成用ケーシングを提供する。【解決手段】地盤Ｄ中に回転させながら貫入し、引き抜く際の杭材料Ｓの排出と打ち戻しを繰り返すことで無振動・無騒音にて締固めて砂杭Ｋを造成する際に使用されるケーシング本体１１を有した砂杭造成用ケーシング１０であって、ケーシング本体１１は、先端開口を横切るように放射状に架け渡され、地盤Ｄを掘削・締固める掘削・締固め部２０を備え、掘削・締固め部２０は、ケーシング本体１１の正回転方向側に地盤Ｄを掘削する掘削部を有すると共に、ケーシング本体１１の逆回転方向側に地盤を締固める締固め面を有する。【選択図】図１
