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.

Abstract: Disclosed is a framing system devised to fit around cables and conduits entering into a concrete structure via an opening through which one wants to pour concrete. The system includes angle-bars, modules fitting into each other and panels. In practice, one incorporates the anchor sleeves in the concrete structure on two opposite sides of the opening where the cables or conduits extend. The angle-bars are then connected to these anchor sleeves. The modules which have recesses adapted to the geometry and size of the cables or conduits, are subsequently attached to the angle-bars. After the cables or conduits are covered with plastic tubes, the panels may be installed outside the structure to complete the framing and concrete may be injected through the opening.
