Breaking reinforced concrete:
The controlled forcce of the hydraulic concrete splitter is very effective in breaking reinforced concrete. This method requires that both the concrete and the concrete. This method requires that both the concrete and the concrete bond on the rod be broken in one operation. The drawing shows a typical rod pattern in concrete.
First a hole is drilled between the rods.The splitter is placed into the hole and positioned(by rotating) so the breaking force will be at 45 degree angle. (heavy arrow with hole shows direction of force). As the concrete breaks on anangle, it moves across the rod both vertically and horizontally. This procedure is repeated each time. The spacing for holes is approximately every two feet on the horizontal, and 18 inches vertically. The 45 degree breaking angle is sued in all holes. If the hole pattern is too far apart, the bond of the concrete tothe rod will not break.
Moving the concrete 1/2 inch apart enables the workmen to remove the broken concrete with light chipping hammers or a small pinch bar.
Heavy walls and slabs can be prespilt and removed iwth targer impact tools. presplitting reduces the time of impact tool operation. A great savings can be realized by using the presplitting method.
If the concrete is very heavily reinforced, the hole spacing of uner 2 is recommneded.
