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.

The invention claimed is: 1. A method for manufacturing, transporting and installing on a building site a prefabricated structure made of reinforced concrete by using an integrated handling system that is removable after the installation is completed, said method comprising: a. manufacturing in a mold the prefabricated structure made of reinforced concrete, by positioning in an upper part of the mold the above-mentioned handling system which comprises external surfaces and fixation means to fix said system in a removable way to the prefabricated structure, and by pouring concrete against the external surfaces of the handling system to form said prefabricated structure directly on it; b. unmoulding the prefabricated structure from the mold by using the handling system; c. installing the prefabricated structure at the building site by using again the handling system; and d. removing the handling system from the prefabricated structure by detaching its fixation means. 2. The method according to claim 1, wherein the handling system comprises a top part and a bottom part that are connected to each other by removable fastening means. 3. The method according to claim 2, wherein the fixation means used to fix the handling system to the prefabricated structure are located on the bottom part of said handling system. 4. The method according to claim 2, wherein the top part of the handling system defines an opening and the bottom part of said handling system comprises separable sides and removable corners. 5. The method according to claim 3, wherein the top part of the handling system defines an opening and the bottom part comprises separable sides and removable corners. 6. The method according to claim 2, wherein the top part of the handling system comprises outside faces with inclined sides to facilitate unmoulding of the prefabricated structure. 7. The method according to claim 3, wherein the top part of the handling system comprises outside faces with inclined sides to facilitate unmoulding of the prefabricated structure. 8. The method according to claim 2, wherein the top part of the handling system is provided with handles. 9. The method according to claim 3, wherein the top part of the handling system is provided with handles. 10. The method according to claim 5, wherein the top part of the handling system comprises outside faces with inclined sides to facilitate unmoulding of the prefabricated structure; and wherein the top part of the handling system is provided with handles. 11. A prefabricated structure made of reinforced concrete with a handling system, which is manufactured by the method according to claim 1. 12. A prefabricated structure made of reinforced concrete with a handling system, which is manufactured by the method according to claim 10.
