CONSTRUCTION METHOD OF ROTARY PRESS-IN PILE AND SLOPE CONSTRUCTION DEVICE

机译:旋压桩和边坡施工装置的施工方法

摘要

PROBLEM TO BE SOLVED: To economically and surely reinforce of the ground of a conventional small-scale slope.;SOLUTION: This slope construction method of a rotary press-in pile pressed in the ground while rotating, comprises a step of scattering a plurality of grout material delivery holes 11c and 12c in the longitudinal direction of a steel pipe pile body on a peripheral wall of the steel pipe pile body of arranging a spiral blade 11a on the tip and rotatably pressing and driving the rotary press-in pile 10 having a plurality of node projections 11b and 12b in the longitudinal direction of the steel pipe pile body in the ground of a slope, a step of pressurizing and injecting a grout material into a steel pipe body of the rotary press-in pile, and a step of forming a ground improving body (a grout column body) 31 by discharging the grout material from the grout material delivery holes.;COPYRIGHT: (C)2009,JPO&INPIT
