PURPOSE:To enhance the strength of joints of concrete by a method in which concrete blocks, each having left- and ritht-handed wings on its base, are erected connectedly to the left and right sides by turning their wing sides toward the natural ground and the adjacent blocks are integrated with PC steel wire. CONSTITUTION:Concrete blocks 1 are set connectedly to the right direction by turning their wing 3 side toward the natural ground. PC steel wire 8 are then thrust through holes 6 from the bases 2 of one-side blocks 1 to the end of the wings 3 and then through the holes 6 from the end of the wings 3 of the other-side blocks 1 to the bases 2, and the PC steel wires 8 are then tensed to fix both end portions of these blocks 1 by fixers 9. Anchors 10 are driven into the ground 7 and their ends are passed through the anchor holes 5 of the blocks 1 and fixed by a fixer 11, thereby fixing the blocks 1 to the natural ground 7. |
