A method of lining a structure by fluid inversion lining, the steps of the method comprising:
- extending a liner through a fluid injection lining apparatus comprising
- a housing;
- a liner feeding assembly coupled to said housing;
- a nozzle coupled to said housing;
- a tubular flexible liner, said liner being insertable through said liner feeding assembly, said liner having a first end couplable to said nozzle forming a fluid seal at said nozzle;
- a fluid injection port in said housing for introducing fluid into an interior of said housing;
- wherein said liner feeding assembly is adjustable for conforming to said liner as said liner passes through said liner feeding assembly such that fluid introduced into said housing through said fluid injection port is prevented from passing out of said housing through said liner feeding assembly whereby fluid pressure between said interior of said housing and said liner draws said liner through said liner feeding assembly and out of said nozzle;
- said liner feeding assembly having a gasket, said gasket having an interior portion, an exterior portion, and a longitudinal slot;
- wherein said exterior portion of said gasket is positioned in a static position against said housing;
- said liner feeding assembly having a pair of wedge members, said wedge members being positioned adjacent to said interior portion of said gasket;
- said liner feeding assembly having a wedge adjustment assembly for urging said pair of wedge members against said interior portion of said gasket whereby said interior portion of said gasket adjacent to said longitudinal slot is pivoted relative to an exterior portion of said gasket to adjust a size of said longitudinal slot;
- said liner feeding assembly having a wedge cradling portion for supporting said pair of wedge members;
- said wedge adjustment assembly having a pair of wedge brackets coupled to said wedge cradling portion adjacent to said pair of wedge members such that said gasket urges said wedge members into contact with said pair of wedge brackets;
- wherein said wedge brackets are adjustably coupled to said wedge cradling portion such that a distance between said wedge cradling portion and said pair of wedge brackets is adjustable;
- said liner feeding assembly having a frame assembly coupled to said housing;
- said wedge cradling portion being removably coupled to said frame assembly;
- said wedge cradling assembly including a pair of cradling members;
- said frame assembly including a pair of frame brackets positioned adjacent to said wedge cradling members such that said wedge cradling members are held against said exterior portion of said gasket;
- a gasket stiffener plate positioned adjacent to said gasket around said longitudinal slot proximate a juncture between said exterior portion of said gasket and said interior portion of said gasket;
- a lubrication injection port in said housing;
- a fluid diversion member positioned in said interior of said housing, said fluid diversion member being positioned proximate said fluid injection port for diverting fluid injected into said interior of said housing towards said nozzle;
- wherein said nozzle is removably coupled to said housing;
- each of said pair of wedge members having a head portion and an extension portion, each said extension portion having a planar surface abutting said exterior portion of said gasket;
- said wedge adjustment assembly including a pair of gross adjustment handles;
- wherein each gross adjustment handle being operationally coupled to an associated one of said wedge brackets such that turning of said gross adjustment handles adjusts said distance between said wedge cradling portion and said pair of wedge brackets;
- said wedge adjustment assembly including a pair of fine adjustment screws;
- wherein each fine adjustment screw being operationally coupled to an associated one of said wedge brackets such that turning of said fine adjustment screws adjusts said distance between said wedge cradling portion and said pair of wedge brackets;
- and
- wherein rotation of said fine adjustment screws produces a smaller adjustment to said distance between said wedge cradling portion and said pair of wedge brackets than an equal amount of rotation of said gross adjustment handles;
- selecting said gasket and said wedge members to correspond to a size of said liner;
- coupling said gasket and said wedge members to said frame assembly using said wedge adjustment assembly;
- coupling said first end of said liner to said nozzle;
- positioning said liner to pass through said longitudinal slot of said gasket;
- adjusting said wedge adjustment assembly to secure said gasket around said liner to inhibit fluid injected into said housing from passing through said longitudinal slot;
- introducing fluid into said interior of said housing through said fluid injection port;
- adjusting pressure within said housing to achieve sufficient pressure to cause said liner to be drawn through said longitudinal slot and out said nozzle.
