PROBLEM TO BE SOLVED: To provide a combination block which is easily and stably installed on the slope of a steep land, and a linked structure using the combination blocks.SOLUTION: This combination block has a structure in which a first extension part 2 and a second extension part 3 are connected to both ends of a base 1 bent at right angle so as to be perpendicular to the base. The base 1 is structured so that a first base 10 extending in the x-axis direction and a second base 11 extending in the y-axis direction are connected to each other at right angle, and a groove 12 having a depth direction in the z-direction is formed therein. The first extension part 2 extends from the opening surface of the base upward in the z-axis direction, and a groove 21 having a depth direction in the y-axis direction is formed in the extended portion 20 thereof. The second extension part 3 extends from the bottom surface of the base downward in the z-axis direction, and a bottomed space 31 is formed in the extended portion 30 thereof. |
