Bored tunnel formwork Piloto de la Línea
Customer: Conlínea (Conconcreto)
Location: Calarcá (Quindio, Colombia)
Rubrica Innovation:The concreting of trenches, allows concreting with a shell while placing and preparing the other thus shortening the production times. The shell is independent of the transfer traveler allowing the use of the same traveler with several shells, thus reducing equipment costs
With the construction of the Pilot Tunnel or guide tunnel of La Linea, it was sought to cross the Central Mountain Range at the level of the municipalities of Calarcá and Cajamarca in the departments of Quindío and Tolima, respectively, by means of an Exploration Tunnel of approximately 8, 6 km.
It was framed in Phase I of the project crossing the central mountain range as the first step of one of the most important infrastructure works for Colombia because it integrates Buenaventura, the main Colombian port on the Pacific coast, with the interior of the country, the Eastern Plains , western Venezuela and the Orinoco Basin.
The Tunnel, which would allow establishing the geological risk of the area to define the definitive tunnel, is 8.5 kilometers long. The tunnel is executed in parallel to the main tunnel and will serve as an emergency tunnel.
