Emergency Repairs of Existing Bridge

CONSTRUCTION PROJECT AND EXECUTION OF THE WORK.

EMERGENCY REPAIRS ON THE BRIDGE OVER THE RIVER NIGER, AT ONITSHA-ASABA (NIGERIA).

The project objective is to reinforce the foundation piles supporting the bridge (built in 1965) linking the cities of Onitsha and Asaba, Nigeria. Because of the strong currents of the river and downs and seasonal rises in water levels, it has been producing a significant erosion of the protective elements of the river bottom.

The technical solution for this purpose, has been the implementation of reinforcing the foundations Jet Groutings upstream of each pier with thirteen piers, of two meters diameter and an average depth of eight meters.
