Quarry & Aggregate Production
ⓒ David H Moloney
Brief Description
Rock is blasted free from the quarry
face and fragmented so it will fit into
the primary crusher. Any oversized
rock is broken with a excavator and
hydraulic Rockbreaker.
At the Crushing and screening yard
the fragmented rock is crushed and
screened into various size ranges.
Concrete Batching Plant David H Moloney
Concrete batching plant comprises -concrete mixer, control cabin, silos for cement and fly ash, aggregate bins and conveyor belt system to feed the mixer. Also aggregate storage bays and water storage tanks. The mixing is computer controlled and has a dynamic screen display, showing the process. Material storage capacity to match two days concrete production

Viaduct Segments Casting David H Moloney
Casting Method
The concrete segments are manufactured
using the short-line, match-casting method.
Match-casting is when sequential segments are poured against the previous cast segment, this ensures that the segments will fit perfectly on site.

Cut & Cover Tunnel Construction
Sequence -Traffic and utilities are diverted, excavate trench, construct & backfill to bury.
To prevent the faces of the excavation from collapsing, different measures are used –
batter the faces, diaphragm walls, secant piles or a combination of soil nailing and
shotcreting.
