Projet
The project consists of the construction of three "03" bridges in the commune of Bopa (Djidjozoun - Lon Agonmé) in the department of Mono, in that of Lalo (Tchi Ahomadegbe - Tchitto) in the department of Couffo and in the department of Collines.
The characteristics of the bridges are as follows:
- Length and type of works
- Dassa bridge in Collines: reinforced concrete bridge (deck and beams) of 120ml over 8 spans of 15 ml and 7 intermediate supports.
- Djidjozoun bridge in Mono: reinforced concrete bridge (deck and beams) of 80ml over 4 spans of 15 ml and 02 spans of 10 ml and 05 intermediate supports.
- Tchi bridge in Couffo: reinforced concrete bridge (deck and beams) of 80ml over 4 spans of 15 ml and 2 spans of 10 ml and 05 intermediate supports.
- Cross-section: Deck with 02 traffic lanes (2x3.5m) and 2 pavements (2x2.00m)
- Support: 02 abutments
- Beams connected by spacers and placed on the girders by means of shrunken neoprene support devices;
- Header shells made of BA resting on the steel piles by means of steel knives; the headers are set into the shells.
- Foundations :
- Djidjozoun Bridge in Mono and Tchi Bridge in Couffo: driven metal piles with an external diameter of 1032mm and average lengths of 20m;
- Bridge at Dassa collines: superficial foundations
- Access ramps: 2 km dam for the Djidjozoun bridge, 3 km for the TCHI bridge in Couffo and 1 km for the Dassa bridge in Collines
- The structures must be designed under permanent loads with a deflection of 0+ resting on Elastomer fretted supports.
