Abstract

PURPOSE:To obtain strong upward pulling load drag by axially mounting a drag plate and a push plate between core plates set up to the upper and lower sections of a rotary bar, turning a turn receiver mounted onto the rotary bar by means of the screw auger and expanding the drag plate. CONSTITUTION:A burying pit is excavated by means of the screw auger 19, and the strain anchor is iserted into the pit. The fitting section 18 of a transmitting tool 16 is fitted and inserted to the turn receiver 9 of the strain anchor, the nose iron 20 of the screw auger 19 is fitted and inserted to an auger receiver 17, and the screw auger 19 is turned. Since the rotary bar 10 is upward moved and a connecting projection 8 is upward moved while a connecting pipe 7 is slid on the upper end surface, the push plates 3 pivotally set up to the lower core plate 5 are outward expanded while using pivotally mounting points 13' as apices together with reinforcing plates 2. The reinforcing plates 2 are expanded using pivotally mounting points 13 as shafts, and the drag plate 1 intrudes forcedly compressing the soil of the side wall of the pit excavated.
