BORING MACHINE AND METHOD OF FITTING IN-SITU PILE IN SOIL

摘要

FIELD: transport, mining.;SUBSTANCE: proposed boring machine comprises a mast, skids fitted on the said mast to move thereon, boring drive arranged on the said skids to rotate drill pipe and tubular bin jointed to aforesaid pipe and furnished with a space for filler intended for filling bore well on pulling the drill pipe out. The said tubular bin is arranged on the skids to axially move relative to the skids. The proposed method consists in feeding the revolving drill pipe into soil by boring drive arranged on the skids mounted to move along the mast towards drilling direction. The required depth reached, the drill pipe is withdrawn back for the hollow space thus formed is filled from aforesaid bin via the drill pipe with the filler. With the drill pipe penetrating downward, the tubular bin is moved, along with the drill pipe, towards the soil relative the skids.;EFFECT: higher efficiency and utility of mining process.;10 cl, 3 dwg
