PROBLEM TO BE SOLVED: To improve workability and constructibility by collecting a number of unit stones to form a square, and arranging a number of connecting tools forming folded anchors at both ends of a flexible metallic wire to show a specified condition, and anchoring the anchors in the unit stones to connect a number of unit stone. SOLUTION: Both ends of a flexible metallic wire 3 made of a steel wire treated with zinc-aluminum alloy plating are bent at right angles to form an anchor 4 and further, the tips of the ends are widened in order to enhance the adhesive force, to prepare many these connecting tools 2. The connecting tools 2 between the peripheral unit stones 1 squarely arranged are linearly arranged lengthwise and crosswise to form a frame-shape and most of the connecting tools 2 between the middle unit stones 1 are obliquely arranged, and the anchors 4 of the connecting tools 2 are fixed in the unit stones 1. In this way, a number of unit stones 1 are connected to form a mat and connecting anchor metal tools 6 are attached to the four corners. These square mats are laid on a ground such as a slope face or the like in accordance with a using area and then, the metal tools 6 are connected to constitute this civil engineering structure formed of connected stones.
