Demolition of heavily
reinforced concrete
- Demolition Blast Furnace Foundations
The Job:
Demolition of the blast
furnace foundations, measuring 16 m long, 16 m wide and 2.8 m high.
The foundations contained 30 mm thick steel reinforcemen
The requirements:
Since
a laboratory was located in the immediate vicinity, blasting, vibrations
and severe shocks were prohibited.
The solution:
First, a Darda DR 086 mini drill rig
was used to drill the necessary holes. The workers then inserted the
three C 11 SN splitting cylinders, powered by an E 2 electric motor
unit, into the drill-holes. Under the combined splitting force of
the cylinders, cracks approximately 5 mm wide were made in the concrete.
A hydraulic chisel was used to expose the reinforcing rods, which
could then be cut through and the concrete broken down into sections.
Without the Darda splitter, which breaks down the structure of the
concrete from inside, the hydraulic breaker would not have succeeded
in demolishing the heavily reinforced concrete. |
