Abstract: Method and system for mapping and/or inspecting an underground pipeline infrastructure, using: a sensor probe for collecting geospatial data while travelling through a pipeline of the pipeline infrastructure, and a driving mechanism comprising a tether, for driving the sensor probe, wherein the sensor probe is provided to enter the pipeline at a vertical angle through a live-fluid entry apparatus and once inside the pipeline make a 90° angle change of direction to align with the orientation of the pipeline.

Abstract: A utility service tee scraping tool having three basic components—a scraper or cutting element, a scraper holder, and an alignment body. The scraper includes a rigid, vertically oriented body to which one or more cutting blades are attached. The scraper holder includes a service pipe tee clamp having two gripping elements with surfaces adapted to fit snugly around the service pipe tee and maintain the tee scraping tool in a fixed position during operation. The tool may be manipulated from above ground. Although particularly suitable for use in keyhole excavations where remote operation of the tool is required, the tool may also be used in traditional excavations.

Abstract: An apparatus for facilitating the use of tools on underground pipeline systems including a socket having a polygonal open end, a pliable socket insert having a polygonal outer circumference corresponding to the polygonal socket opening adapted to fit snugly into the polygonal opening and flush with the open end of the socket and a locking device by which the socket insert is maintained within the socket during use. The socket insert is provided with a plurality of pliant inwardly extending projections which deform to the size and geometry of the tool to be employed when the socket is pressed onto the tool.

Abstract: A self-adjusting wrench having an elongated drive handle (40) and an adjustable wrench assembly (10) connected with one end of the elongated drive handle. The adjustable wrench assembly includes a pair of opposed jaws (11, 12) disposed at an angle with respect to the longitudinal axis of the elongated drive handle.
