AUGER SCREW AND GROUND REINFORCEMENT METHOD
PROBLEM TO BE SOLVED: To provide an auger screw and a ground reinforcement method that can achieve boring drilling while suitably reducing a soil removal amount, and thus attain superior workability.SOLUTION: An auger screw A comprises a screw shaft 2 which comprises a drilling bit 1 at a tip part and is supported rotatably on an axis O1, and a screw blade 3 which protrudes outward from an outer peripheral surface of the screw shaft 2 in one body and is provided spirally while twisted to a rear side in a sequential forward rotating direction from a front end side to a rear end side along the axis O1, the screw shaft 2 being formed in stages to be larger in diameter as arranged more on the rear end side than on the front end side along the axis O1.SELECTED DRAWING: Figure 1
【課題】好適に排土量を削減して穿孔掘削することを可能にし、優れた施工性を実現可能なオーガスクリュー及び地盤補強工法を提供する。【解決手段】先端部に掘削ビット１を備え、軸線Ｏ１周りに回転可能に支持されるスクリュー軸２と、スクリュー軸２の外周面から外側に一体に突設されるとともに軸線Ｏ１方向先端側から後端側に向かうに従い順次正回転方向後方側に捻じれる螺旋状に設けられたスクリューブレード３とを備えるオーガスクリューＡにおいて、スクリュー軸２を、軸線Ｏ１方向先端側から後端側に配されるほどに大径になる多段状に形成する。【選択図】図１
