摘要:
During the installation of underground utilities it is common to utilize an earthmoving machine, such as a hydraulic excavator, to dig a trench and aid in the placement of the individual pipe segments that comprise a conduit or pipeline. Normal placement of the pipe segments require communication between the excavator operator and a laborer that is positioned adjacent the pipe in the trench. As the pipe segments are lowered into position, the laborer insures a proper connection, support, and sealing of each joint in the pipeline. The requirement of another individual in the trench is both inefficient and represents a significant increase in the cost of laying the pipeline. The present invention utilizes a pipe handling apparatus that may be inserted within a segment of pipe with an end face thereof bearing against a flange defined by a pipe supporting cylinder. This connection allows the operator to apply a force to the pipe segment in the direction of engagement with the pipeline to insure connection. A spraying apparatus is defined by the pipe handling apparatus in the pipe at a location that is generally coincident with the pipe joint Upon activation, the spraying apparatus will provide a coating of sealant entirely around the internal portion of the pipe joint. This apparatus permits the excavator operator to dig a trench and set and seal the segments of a pipeline without the aid of additional personnel.
