METHOD AND DEVICE FOR BUILDING SOIL CEMENT POLE IN STEEL PIPE POLE TRAIN EARTH RETAINING 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 4, an erection hole 10 for a steel pipe pile is excavated along an existing steel pipe pile B serving as a guide. A number of protrusion bodies 7 are formed on the stabilizer side 4 arranged at the auger screw A and a number of protrusion bodies 8 are formed facing each other on the rotary shaft 1 side of the auger screw A between the fixed protrusion bodies 7 and 7. By the protrusion bodies 7 and 8, a lifting excavated soil lump is crushed and injecting cement milk and excavated soil are mixed and agitated together to build a soil cement pole.;COPYRIGHT: (C)1998,JPO
