ALE completes incremental aqueduct launch in Argentina
ALE has successfully completed the incremental launch of a concrete aqueduct of 11,200t in the Province of Córdoba, Argentina.
ALE started launching the aqueduct, comprised of 44 voussoir sections, on August 2015 reaching a total length of 1,100m and was completed in a period of sixteen months. When completed, jacking was executed to settle it on definitive supports.
The typical incremental section measured 25m length and weighed 250t, and was launched every 10 days.
Once the 23rd voussoir section was installed, the aqueduct weighed 5,750t and measured 575m long and it represented the longest structure to ever be launched in a single operation in Argentina.
Each incremental section was launched by linking it on its back and moved using two 200t strand jacks and two 190t jacking systems. Once the manoeuvre was complete, a new section was constructed and the ALE equipment linked it on its back again. Every manoeuvre took almost five hours to be complete.
Hernan Asensio, ALE Project Manager, said: “This project represented a huge challenge for us, considering the sheer weight and dimensions of the structure. We are very proud to have been involved in such a landmark project.”
