<p>The present invention relates to a mobile unit for relining pipes, comprising: an inverter (4) for laying and pressurizing a sheath (6) of composite material (5) for reconditioning underground conduits (3); and a volute (11) having a connection opening (11a) and an expulsion opening (11b). The unit is provided with fast-locking means (14) operationally arranged between the inverter (4) and the volute (11) so as to lock them hermetically together. The unit (1) also comprises a blower (30a) for applying a predetermined pressure to the inverter (4) and the sheath, inflating the sheath (6) and providing a suitable air flow for the heating step. Finally, the unit (1) comprises a boiler (34a) for generating steam. The boiler (34a) is able to supply steam inside the inverter where it is mixed with the air in a controlled manner and then passes through the sheath (6) at a temperature sufficient to cause hardening of the composite material (5) when the sheath (6) is at least partially inserted inside the conduit (3) to be repaired and/or relined.</p> |
