Other issues on the construction of caissons
-
Installation holes (0.20 m), at 2.00 m height from the base with PVC pattern.
-
Hooks made of forced steel for towage (at 9.50 m height from the base)
-
Expected connection between caissons and superstructures
-
4 bollards for installation
Additional Procedures
- Removal of lifting jacks and rods with the sleeves (at the end of concrete construction)
- Lifting of steel formwork
- Cleaning of accessories and steel formwork from residual paraffin and coating with a new layer for the new concrete construction
- Placing of plugs on the 24 expansion holes with the help of a barge and a construction crane
- Ballasting with Viso concrete
- Descending of the caisson and removing it from the machine
- Elevation of platform (duration: 4-5 hours)
Concrete Quality
- B300 Quality (C25)
- Reduced water-permeability
- Pumping
- Quick delivery of required strengths (due to the sliding steel formwork)
- Liquidizer
- Use of plastic fibres (as a additional protection of the reinforcement)
