ABSTRACT:
A method and apparatus for applying a liner to a pipe is disclosed. The apparatus includes a base assembly having a plurality of guide rails and a shuttle plate attached thereto. The apparatus also includes a motor module attached to an end of the base assembly. An extension arm is connected to a top surface of the shuttle plate. The extension arm has a spray head assembly attached at an opposite end thereof. The extension arm and spray head assembly will move relative to the base assembly of the apparatus. A fast cure coating will be applied via the spray head assembly to the interior surface of a pipe being rehabilitated. The spray head assembly will have an air blow off mechanism therein thus allowing for the tip of the spray head assembly to stay relatively clog free during the fast cure coating operation of the apparatus. The methodology also includes an oscillation system wherein the spray head assembly will move relative to the base assembly thus creating an over lapping pattern for the spray coating being applied to the interior surface of the pipeline. This oscillation system will allow for a more uniform coating to be applied.
