Tech/Engineering - Construction / Civil Engineering / Construction of a viaduct
Spanish term or phrase: cimbra porticada
Describing the construction of a railway viaduct in Spain:

El arranque del arco se ejecuta mediante la disposición previa de una ***cimbra porticada*** apoyada directamente sobre el terreno. Sobre la estructura metálica colocada en su coronación se monta el encofrado del arco. Una vez colocada la armadura, se hormigona la primera fracción del arco, cuya sección es hueca.

Explanation:
This comes directly from my notes, but I don't recall the circumstances and I don't have time to look into this now (when is your deadline?). When I say "I think" in my notes, it means that I am not sure, but that this is the conclusion I came to whilst researching it/something related. Anyway, I hope it helps, and I will try to come back to this question.

cimbra porticada = falsework bents (I think this is what it is. A trestle is much lighter and cannot support as much weight. A bent has two columns and a cap/horizontal beam)

See link for arch bridge construction and please supply as much info about the construction method as possible.

I have a feeling that this cimbra porticada may be referring to Kwikform's falsework, in which case it could be a truss and prop shoring system, but there is just not enough info on the Internet in Spanish about this, and I have no more time.

This is what I think the porticada refers to though (lattice-type arrangement):

Notes to answerer
Asker: Hi Nikki - my deadline is 12 noon today. The viaduct is for a railway line, is 587 metres long with an arch span 261 m. Here are the surrounding paragraphs in Spanish: La complejidad del proyecto viene dada tanto por los distintos sistemas constructivos que se utilizan dentro de la misma estructura (cimbra de avance, porticada y dovelas sucesivas atirantadas) como por la necesidad de ejecutar unas pilas de 40 metros de altura que deberán ser demolidos al finalizar la ejecución. Cada uno de estos apoyos provisionales, con sección hueca, se construyen mediante un sistema de encofrado autotrepante, similar al de las pilas definitivas del viaducto. El arranque del arco se ejecuta mediante la disposición previa de una cimbra porticada apoyada directamente sobre el terreno. Sobre la estructura metálica colocada en su coronación se monta el encofrado del arco. Una vez colocada la armadura, se hormigona la primera fracción del arco, cuya sección es hueca. Sobre la parte de arco, ya construida, se levantan las pilas definitivas, siguiendo idéntico esquema que en el resto del viaducto en la zona de acceso. El tablero, formado por una viga cajón de hormigón postesado, se ejecuta mediante una cimbra autoportante, siguiendo un procedimiento clásico y se detiene al alcanzar la zona próxima al embalse.


Peer comments on this answer (and responses from the answerer)
agree  esmeralda10: Nikki, yes, pórtico - frame, lattice-type, etc. As far as I know, you can just use falsework, which is a temporary system. See http://www.sciglobal.com/formwork/special.html. (they are using formwork and falsework as synonyms). [Yes, I know.]

  -> strictly speaking falsework and formwork are different.

disagree  Nikitaco: "Arch form" is a type of form (an arch), not a steel structure to build anything (as "cimbra" is)
