Description
This emblematic project of the City of Lima involves the construction of a 12.5 km long elevated viaduct and 8 train stations. The train is going to solve traffic problems and the chaos of public transport suffered by more than 300,000 passengers every day.
ULMA solution
Faced with different structures and short lead times, ULMA decided in favour of the MK system as primary solution for all configurations.A qualified team and powerful logistics ensured the material supply within the agreed deadlines.
ENKOFORM VMK was used as vertical formwork for the more than 400 piers of the viaduct.
The formwork exceeding 7 meters height and of octagonal section had to withstand the high concrete pressure. For the bottom and sides of the pier caps, ENKOFORM HMK formwork shored by ALUPROP towers was used. The same systems combined with NEVI and COMAIN formwork were applied to the bottom of slab and beam.
For the curved sections where no pre-stressed beams were required, MK as well as ALUPROP towers were used to sustain 108 t in each case (27 t per support point).
The versatility of the MK system eased the installation of a pedestrian bridge and a structure for vehicle traffic. This way, the high demands of the customer have been fulfilled by far.
