Incatema advances the reinforcement steel and concreting of the floor slab for the working shaft of the Cambérène emissary (Senegal)

9 December, 2021

Incatema Consulting & Engineering has completed installation of the reinforcements and concreting of the floor slab for the working shaft of the emissary under construction in Cambérène, north of Senegal’s capital, Dakar city.

This working shaft will serve to introduce the tunnel-boring equipment that will be used to execute the micro-tunnel, and additionally as the site for the future connection of the land and sea segments of the outfall.

Now that the floor slab has been concreted, work continues apace on execution of the shaft walls, with completion being scheduled for the end of the year.

At the same time, the contract has been signed for manufacture and supply by a Spanish company of the reinforced concrete pipe that will line the micro-tunnel. The plan is for its manufacture to start in the first fortnight of December, to which effect the necessary materials are being procured. The duration of the manufacturing process is estimated in 5 months, such that by the end of April 2022 the whole of the pipe, 1,200 linear metres, will be ready in Dakar.

Also, the plan is to deliver the drilling equipment in the months of April and May so that boring of the tunnel can begin on 1 June 2022.

After the working shaft has been executed, the emissary pipes will be installed, as previously reported here.
