One of the most important phases of the Panama Canal Expansion Program has begun. While the surfaces of the two new locks were levelled with concrete in March, permanent concrete work is now underway.
On the Atlantic site, structural marine concrete has been poured, shaping the lock’s upper chamber. Using specialised industrial formwork, one hundred cubic meter blocks of cement have been laid to form the upper chamber’s floor. The concrete mix used has been designed to guarantee a minimum service life of 100 years.
On the Pacific side, work has commenced on the construction of a pit for the first of three lock crossunders (tunnels). The crossunders will house trays and pipes for communication and electricity cables, drinking water pipes and other elements required to operate the lock.
Who knows how locks work? It’s quite mind-boggling so please share with us!
