It pulls in natural slant face stabilization construction method and the bearing pressure component

摘要

PROBLEM TO BE SOLVED: To provide a natural-slope stabilizing construction method capable of effectively stabilizing a natural slope while preferably maintaining the natural slope. ;SOLUTION: A tensile member 12 such as an anchor rod is penetrated into a ground on a natural slope 11 first while the front end section of the tensile member 12 is fixed onto a hard foundation ground 13. A downward conical body-shaped member 15 is arranged onto the upper section of the tensile member 12, and the conical body- shaped member 15 is pushed in by any means from a ground surface, and buried into the ground. A bearing member 14 is disposed to the ground projecting section of the tensile member 12, a tensile force is given to the tensile member 12 bearing force to a stratum between the conical body-shaped member 15 and the hard foundation ground 13 is worked to the bearing member 14 receiving the reaction of the tensile force and the conical body-shaped member 15 on the underside of the bearing member 14 and the natural slope 11 of interest is stabilized by the bearing effect. Accordingly, the bearing effect in the bearing member 14 is increased by the working of the conical body-shaped member 15, and a slope stabilizing effect is improved. Since the natural slope is not excavated, the natural slope is maintained preferably.;COPYRIGHT: (C)1999,JPO
