A bolt insertion hole 2 is provided passing through between -3 and a-3, and the top and bottom of the side surface a-3 are flat, and most of the side surface is deformed with one side forming a concave arc surface and the other side forming a convex arc surface. It has a columnar cross-section. A large number of unit blocks a are connected to each other in an abutting manner with their concave and convex arcuate surfaces in contact with each other on their side surfaces a-3, forming one-piece segments as shown in FIGS. 2 to 4, The upper and lower surfaces a-1 and a-2 form an arc.

In this invention, as mentioned above, the upper and lower surfaces of many unit blocks, bolt insertion holes, and long bolts are curved with the same curvature, so by inserting each unit block and tightening the long bolts, a predetermined curvature can be achieved. Mottled segments are easily obtained.
In addition, the joint surfaces of the unit blocks are flat on the top and bottom, and most of the side surfaces are a concave arc surface on one side and a convex arc surface on the other side, so the unevenness meshes with each other and reduces dimensional errors in each unit block. Since there are flat surfaces on the top and bottom, the cross-sectional shape of the unit block is difficult to chip. Moreover, since it can be delivered in unit blocks and easily assembled on site, the efficiency of transportation work is improved and overall labor savings can be achieved.
また単位コンクリートブロツクを成型する場合
には型枠が小型化し、コストダウンが図れる。 Furthermore, when molding unit concrete blocks, the formwork can be made smaller and costs can be reduced.
