Method of spray lining a pipe with an environmentally compatible impervious membrane
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 method of spray lining a pipe, conduit, structure or passageway comprises connecting a liner supply umbilical to an in situ pipe spray liner device, connecting equipment control cables, air supply hose, electrical supply and controls for the two part liner, connecting an air supply to motors, connecting the liner supply hoses to the impingement block, connecting the air supply to one or more air motors powering a servo drive and maintaining the nozzle in the center of the pipe using a remotely controlled rotation table or scissor leg table. 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.
1. A method of spray lining a pipe, conduit, structure or passageway comprising the steps of:
(a) connecting a liner supply umbilical to an in situ pipe spray liner device wherein the umbilical comprises separate hoses for a two part liner components, an electrical supply, an air supply hose, cctv connection and equipment control cables;
(b) connecting the cctv connection, equipment control cables, air supply hose, electrical supply and controls for the two part liner to a remote control location;
(c) connecting an air supply to motors powering the in situ pipe spray liner device track system;
(d) connecting the liner supply hoses to an impingement block;
(e) connecting the air supply to one or more air motors powering a servo drive for extending the spray nozzle forward and backward and to rotate the spray nozzle and install liner on the inside wall of the pipe, conduit, structure or passageway; and
(f) maintaining the nozzle in the center of the pipe, conduit, structure or passageway using a remotely controlled rotation table or scissor leg table.
2. The method of claim 1 further comprising remotely adjusting the pressures, velocities and the flows of liner material stream to the in situ pipe spray liner device via a liner supply umbilical connection that are directed to a spray nozzle component.
3. The method of claim 1 further comprising the spray lining of pipe, conduit, structure or passageway without placing one or more operators within the pipe, conduit, structure or passageway or pipe, conduit, structure or passageway access during the spray lining.
