Abstract
A method for manufacturing, transporting and installing on a building site a prefabricated structure made of reinforced concrete for the replacement of a structure such as a manhole, access chamber, access vault, junction box or other, which is buried in the ground and is part of an underground network such as a sewer, aqueduct, gas, electrical distribution, telecommunications, cable television and the like. In this method, concrete is poured in factory against the external surfaces of an integrated removable handling system, which is used as top part of a mold for manufacturing the prefabricated structure. The handling system is fixed to the prefabricated structure in a removable manner. The handling system remains in place during the subsequent steps of unmoulding, transporting and installing the prefabricated structure to the building site. Finally, once the installation is completed, the handling system is removed from the structure.
