1. A vacuum excavation system for excavating material from a site, comprising:
a. a first vehicle; b. a vacuum assembly mounted on the first vehicle, the vacuum assembly comprising:
i. a material storage tank,ii. a vacuum pump having an intake port and a discharge port, the discharge port operatively attachable to the material storage tank to permit material discharged from the vacuum pump to be received in the material storage tank,iii. an elongated vacuum hose having an intake end and a discharge end, the discharge end operatively attachable to the intake port of the vacuum pump; c. a high pressure fluid delivery assembly comprising:
i. a fluid pump having an input port operatively attachable to a fluid supply tank to receive fluid and a discharge port to discharge at high pressure fluid entering the input port,ii. piping operatively attached at its input end to the output port of the fluid pump to receive the high pressure fluid from the fluid pump; d. a power source operatively connected to the vacuum assembly to provide power to operate the vacuum pump and to the high pressure fluid delivery assembly to provide power to operate the fluid pump; e. a second vehicle, the second vehicle having an extendable, articulating arm with an accessory mounting structure mounted on the arm; f. an excavator assembly comprising:
a. a mounting adaptor attachable to the accessory mounting structure wherein the arm can operatively position the excavator assembly at the site being excavated;b. a rigid excavator tube attachable to the mounting adapter, the excavator tube having an intake port and a discharge port, the discharge port operatively attachable at one end to the intake end of the vacuum hose; andc. a fluid jetting assembly affixed to the excavator tube having a nozzle assembly operatively attachable to the discharge end of the fluid piping to receive and redirect the fluid under pressure to the site to be excavated. |
