PROBLEM TO BE SOLVED: To reduce construction cost and prevent natural stones from being collapsed after installation in a masonry work structure applicable to revetment for rivers and lakes. SOLUTION: A support net 5 is installed forward of a slope, and a plurality of natural stones 6 are piled up forward of the support net 5 in such a state that they are connected to the support net 5 through anchor shafts 7. The support net 5 is curved according to the depths of the natural stones 6 so that the lengths of the anchor shafts 7 can be aligned with each other. By this, a variety of anchor shafts 7 with different lengths must not be carried into a site. When the anchor shafts 7 are secured to the natural stones 6 with anchors, curing control for adhesion can be eliminated. COPYRIGHT: (C)2007,JPO&INPIT
