ABSTRACT:
A computer controlled concrete injector pump and process for lining pipe comprises a pump chamber having an outlet connected to a spray lance through a first check valve and having first and second inlets, one inlet being connected through a second check valve to a hopper, and the second inlet being connected to an injector tube having a piston moveable therein by a hydraulic cylinder. The hydraulic cylinder is controlled by a programmable logic controller in a control system which has provisions for operator input of lining process parameters. The volume and flow rate of material from the pump may be controlled accurately by controlling the movement of the piston within the injector tube. The valve housing of the second check valve between the chamber and the hopper is split into two portions which are connected by a quick-disconnect coupling. The valve housing may be separated for access to its interior for maintenance and cleaning.
