ABSTRACT:
A method and apparatus is disclosed for remotely and robotically installing an organic, monolithic, structural and non structural, circumferential and partial radius membranes in conduits, pipelines or passageways. The included apparatus has the mechanical function to manually or automatically center the liner dissipation device in any geometrical shape. The included apparatus possesses the remote controlled capability to manipulate centrifugal dissipation of the liner to afford consistent thickness on any shaped profile or flat surface of the pipe wall surface. The apparatus includes a manual or automatic mechanical scissoring device for elevation changes and a manual or automatic rotational table for shaft alignment. The apparatus includes a means of automated self alignment by way of proximity sensors. The pendulum oscillation bracketing incorporates a fluid driven motor assembly communicating with a bored shaft and integrates as many as two offset dissipation devices. The included apparatus has both fluid and electrical rotary unions to transmit fluids and current from fixed ports to a rotating shaft assembly. The included apparatus has a mechanical function facilitating cutting and retrieval of cured spray build up on the spray orifice. This method and apparatus will allow for continuous lining applications of any thickness in one pass, in conduits and passageways employing multi component liquid polymers with rapid mechanical properties formation.
