摘要： A device for coupling to a working end of a hydrovac boom hose is disclosed. The device includes a tubular suction tube configured for removably coupling to the working end of the hydrovac boom hose such that an opening of the working end remains unobstructed. A plurality of high pressure water jet nozzles is located around a circumference of the tubular suction tube such that the water jet nozzles surround the working end of the hydrovac boom hose to dislodge earthly materials under the device. The high pressure water jet nozzles are configured for emitting high pressure that dislodge earthly material. A cylindrical housing to enclose and protect the tubular suction tube, water jet nozzles, locating device and provide an air duct for the ambient air to pass down threw. A plurality of air vents in the cylindrical housing that provide flow of ambient air to an area being excavated. The conduit coupled with the cylindrical housing, the conduit for allowing ingress of water to the plurality of high pressure water jet nozzles.

摘要： The present invention is directed to a method and apparatus for making point-repairs in sewer and other utility lines. The method involves positioning a section of polyolefin, preferably polyethylene, pipe by drawing or pulling it into and through the undamaged portion of the damaged sewer line requiring repair and fixing or securing from the surface the section of polyolefin pipe into place. The present invention is also directed to point-repair collapsible heads and a point-repair insertion tool for assisting in the positioning of the section of polyolefin pipe into the damaged sewer line requiring repair by pulling the point-repair insertion tool which includes the section through the line to the place where repair is required and collapsing the heads and removing them by cable from the section and the damaged sewer line.
