BUILDING METHOD FOR SOIL CEMENT POLE IN STEEL PIPE POLE TRAIN EARTH RETRAINING WALL CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To improve mixture agitation ability of excavated soil and cement, in a steel pipe pole train earth retaining wall construction method. ;SOLUTION: By using an auger screw A with a stabilizer 6, an erection hole 13 for a steel pipe pile is excavated along an existing steel pipe pile B serving as a guide. A protrusion body 8 not co-rotating with a helical vane 2 is arranged at bearing bodies 4 and 4 to support the stabilizer 6 arranged at the auger screw A. The protrusion body crushes excavated soil lifted by a helical vane 2 and mixes and agitates injected cement milk and excavated soil to build a soil cement pole.;COPYRIGHT: (C)1998,JPO
