Abstract:
An insulated excavation tube preferably includes a non-conductive tip tube, a non-conductive connector tube, a first vacuum tube, a second vacuum tube, a flange member and a handle. One end of the first vacuum tube is retained in one end of the non-conductive tip tube. A distance is maintained between an end of the first vacuum tube and an opposing end of the non-conductive tip tube to provide electrical and vibration isolation. An opposing end of the first vacuum tube is retained in one end of the non-conductive connector tube. One end of the second vacuum tube is retained in the non-conductive connector tube. A gap is maintained between the opposing end of the first vacuum tube and the one end of the second vacuum tube. The flange member is attached to an opposing end of the second vacuum tube. The handle is attached to the second vacuum tube.
