摘要： For the construction step by step of a reinforced concrete bridge, the portions of the bridge are reinforced and concreted on site by using a shuttering (17) fixed to a centering (16). After the setting of the concrete and withdrawal of auxiliary supports (30) (in the case where the portion in question does not rest on a main pile (12)), the centering is lowered with the casing on rails (32) of a portion and lifted at the level of the lower part of the bridge. Then a new deshuttering is made. In the case of settling grounds, the rear end of the centering may whereby be anchored at the end of the previously completed portion. In order to allow the centering to move beyond the pile, respectively beyond the auxiliary supports, arrangements are made so as to allow to move all the portions of the centering or of the casing which are located in the section of the piles or the support, beyond that section. To this effect, the transverse beams (41, 42) are displaceably arranged on longitudinal beams (48) and the shuttering plates on the lower portion may be folded back downwardly. This folding back is effected progressively on the length of the scaffolding.
