- Concrete casting equipment
- Handling and Evacuation of blocks
The setting of four different areas: casting, curing, demoulding and evacuation line
Two hoppers pour the concrete in the openings on the top of the mould. The cabin rises as the mould is filled in order to keep a constant height fall.
In order to accelerate the compacting of the concrete, the mould advances in a heat insulated space called the curing chamber. When a mould enters into it, another one exits, ready to be demoulded. This operation is entirely automatic and does not require the presence of any worker or operator. There is also the possiblity of a natural drying, therefore without a curing chamber, which requires more time to do the process.
Once the armour unit is demoulded, it is sent towards an area called the evacuation line. There, a handling equipment takes the block and brings it on the stockyard situated outside the plant. The process is also automatic.
have a look at the plant installed by APS on Reunion IslandStaff :
- Mould preparation : 2
- Oversight/Management : 1
Technical details :
- Surface : 2 700 m²
- 1 block every 15 min during 8h
- Cycle time : between 10 and 16 min depending on the mould
- 36 moulds + 36 concrete pieces in constant circulation
- Mould sizes : 4, 6, 8 and 11 m3
- Total number of moulds : 105
- Weight : from 10 up to 33 tonnes depending on the mould
- Natural drying
- Because there is not a curing chamber on this project, a mould needs to wait for 24h on a stockage line before to be demoulded and then again 24h on another stockage line before to be sent on the evacuation line.
