MANUFACTURING METHOD OF INSPECTION FRAME, INSPECTION FRAME AND SLOPE FACE PROTECTIVE ENGINEERING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inspection frame and a slope face protective engineering method in which workability is improved while reducing time and efforts.;SOLUTION: A manufacturing method of an inspection frame is provided in which upper and lower two stages of cores can be fixed on a slope face and the inspection frame comprises wires and is used for regulating a shape dimension of a swollen body including the cores when forming the swollen body. The manufacturing method includes: a step of forming a first inclined portion 5 that becomes a standard for a swollen body shape; a step of forming a first approximately V-shaped portion 6 for placing the upper core therein; a step of forming a second inclined portion 7 that becomes a standard for the swollen body shape; a step of forming a connecting portion 8 to a next first approximately Λ-shaped portion 9; a step of forming the first approximately Λ-shaped portion 9 for holding the lower core in such a manner as to float it; a step of forming a connecting portion 10 to a next second approximately Λ-shaped portion 11; a step of forming the second approximately Λ-shaped portion 11 for holding the lower core in such a manner as to float it; a step of forming a connecting portion 12 to a next third inclined portion 13; a step of forming the third inclined portion 13 that becomes a standard for the swollen body shape; a step of forming a second approximately V-shaped portion 14 for placing the upper core therein; and a step of forming a fourth inclined portion 15 that becomes a standard for the shape of the swollen body M.;COPYRIGHT: (C)2013,JPO&INPIT
