Description of Works:
Drilling and blasting of 5000m of rock in downtown Airlie Beach with the
closest house being 150m from blast. Result excellent. All material was
able to be dug with a 20 tonne excavator and saved approximately 5
months in construction time (if other methods of rock breaking had been
chosen). Also some temp ground support by way of ground anchors to high
unstable embankments was performed as well as some permanent ground
anchors for retaining wall.
Project: Scrubby
Hill - Shoreline Residential Subdivision
Client: Civdec Constructions
Location: Airlie Beach, North Queensland
Period: March 2004
Description of Works: Large boulders amongst material on steep
slopes above embankment had to be restrained or broken to a size less
than 1m³ to enable rock catch fence to work successfully. Boulders were
drilled by hand and low powered rock breaking products were used to
break up rocks to a suitable size. It was critical that very low
vibrations were made so as not to create a landslide. Some hand drilling
and rockbolting of boulders were also performed and restrained with
steel wire rope and rockfall netting. |
