DRILLING MACHINE, DRILLING METHOD, AND CLEANING METHOD
PROBLEM TO BE SOLVED: To provide a drilling machine that can reliably wash slime accumulated on joints of a pile hole and discharge it to the ground.SOLUTION: A drilling machine 1, which is used for a reverse circulation type drilling method and configures a pile hole 25 by drilling soil while sucking drilled sediment with mud and discharging them to the ground, comprises a drilling machine body 2 with a suction pump 9 and a suction pipe 10 for sucking drilled sediment with mud and discharging them to the ground, and a cleaning means 11, which is branched from the suction pipe 10 and ejects in the lateral direction a part of mud 30 sucked by the suction pump 9, is provided on a part of the drilling machine body 2.
【課題】 杭孔の節部に堆積したスライムを確実に洗い落として地上に排出させることができる掘削機を提供する。【解決手段】 地盤を掘削しながら掘削土砂を泥水と共に吸い上げて地上に排出させることにより杭孔２５を構築する逆循環方式の掘削工法に用いられる掘削機１であって、掘削土砂を泥水と共に吸い上げて地上に排出させるサクションポンプ９とサクションパイプ１０とを備えた掘削機本体２を備え、前記掘削機本体２の一部に、前記サクションパイプ１０から分岐して、前記サクションポンプ９により吸い上げた泥水３０の一部を側方に向けて噴射させる洗浄手段１１を設けた掘削機。【選択図】 図１
