Wall formwork
Hydraulic prison perimeter wall formwork
The perimeter wall of this prison is perfect for the use of a fully hydraulic and self-propelled formwork.
- Length of the wall 970m’ (2 x 325m and 2 x 160m)
- Height of the wall including top sphere 6,4m
- Wall thickness 280mm
- Diameter top sphere 1m
- Standard length of pouring phase 14,7m
- Formwork made of 7 equal parts of 2,1m wide
- Accentuated joints with changing positions
- No tie-bars through the wall, only through the kicker and above the wall
- Concrete is pumped from below with self-compacting concrete
- Maximum deflection of 3mm over 6,4m height at a maximum concrete pressure of 160kN/m²
- Formwork is suspended from a portal frame which can be moved hydraulically
- Opening and closing of the formwork is carried out hydraulically
- Width of the foundation base is 2,5m, the portal frame carries over a length of more than 15m, hence the formwork can be opened sufficiently for cleaning purposes
- Height adjustment with jacks
- Portal frame and formwork can be converted tolower heights
The 4 outer corners are poured first using special corner pieces. After which the formwork is suspended in the portal frame to make the straight walls.
