Claim:
A process for the construction of a segment of an open-air work by prefabricated structural members of reinforced concrete, comprising the steps of: arranging a first and a second prefabricated structural members, each of which includes an upright portion and at least a cover portion connected to the upright portion, installing the first structural member by resting a free end of its upright portion on a respective foundation portion, installing the second structural member by resting a free end of its upright portion on a respective foundation portion, in such a manner that the two structural members are arranged symmetrically so that the free ends of the cover portions thereof are arranged mutually opposite and in substantial contact to each other, both said structural members being so shaped that the cover portions thereof define respective elongated cavities which are open upwards and are axially open at their free ends, and extend substantially on the overall length of said cover portions, said cavities of the two structural members being arranged, during the installation step, so that they are substantially aligned in order to constitute a continuous elongated channel open upwards wherein a casting is executed during the work in order to make a continuous beam within said elongated channel, said beam being superimposed to both the structural members and fastened to them.
