A system for straightening downwardly-bowed underground pipeline using a means of pumping expandable fluid into substratum below the pipeline bow. The system includes an apparatus for identifying the bowed section of underground pipeline, and a device for delivering expandable liquid to the target site beneath the pipeline bow. The apparatus includes a frame supporting a series of probe-rods driven into contact with the top of the pipeline, to locate the bowed section. The device for straightening downwardly-bowed underground pipeline uses a means of pumping expandable fluid into substratum below the pipeline bow; the device comprises an elongated shaft having a trailing end and a leading end and defining a fluid pathway from the upstream trailing end to the downstream leading end. The trailing end is adapted to secure fluid communication between the fluid pathway and the means of pumping expandable fluid, and the fluid pathway terminates in at least one downstream fluid pathway exit; the leading end also including a means of shielding said pathway exit and diverting the fluid from continued downstream travel.
A device for straightening downwardly-bowed underground pipeline using a means of pumping expandable fluid into substratum below the pipeline bow, the device comprising an elongated shaft comprising a trailing end and a leading end and defining a fluid pathway from the upstream trailing end to the downstream leading end, said trailing end adapted to secure fluid communication between said fluid pathway and the means of pumping expandable fluid, said fluid pathway terminating in at least one downstream fluid pathway exit, said leading end further comprising a tip converging to a point leading an overhang portion of the leading end formed by reducing the thickness of the leading end before the fluid pathway exit, at least perpendicularly to the fluid pathway and without any thickening of the leading end between the fluid pathway exit and the point, thereby shielding the fluid pathway exit while the tip is being pushed down into the soil, and reducing clogging of the fluid pathway exit by dirt or other debris.
A device for straightening downwardly-bowed underground pipeline using a means of pumping expandable fluid into substratum below the pipeline bow, the device comprising an elongated shaft comprising a trailing end and a leading end and defining a fluid pathway from the upstream trailing end to the downstream leading end, said trailing end adapted to secure fluid communication between said fluid pathway and the means of pumping expandable fluid, said fluid pathway terminating in a first lateral fluid pathway exit and a second lateral fluid pathway exit on the opposite side of said shaft, said leading end comprising a tip converging to a point leading an overhang portion of the leading end formed by reducing the thickness of the leading end before each fluid pathway exit, at least perpendicularly to the fluid pathway and without any thickening of the leading end between the respective fluid pathway exit and the point, thereby shielding each respective fluid pathway exit while the tip is being pushed down into the soil, and reducing clogging of the respective fluid pathway exit by dirt or other debris.
