The system has an uncoupling system (18) to uncouple the box relative to support legs (4) of bottom (3). The uncoupling system has a pin (21) extending outwardly from the bottom and a tubular leg forming barrel closed at a free end (4-1) and opened at another end for being engaged on the pin and stopped against the bottom. The uncoupling system has a removing system to remove attachment of the box relative to the structure. An independent claim is also included for a method for installation of pipes in a concrete slab.
