Claims
- 1. An excavation suctioning device comprising a cylindrical reservoir having a fluid inlet tube, the reservoir for receiving pressurized fluid; a first tube connected to said reservoir, said first tube having a material inlet portion, a central portion and a material outlet portion, said central portion of said first tube being located within and in parallel spaced relationship to said reservoir; a second tube, said second tube having an open end located axially opposed to the reservoir and a connection end operably connected to said reservoir, said second tube surrounding substantially 1/3 of the length of said material outlet portion of said first tube and thereby forming an elongated space between said second tube and said material outlet portion of said first tube; a means coupling said reservoir and said space to permit a fluid output of said reservoir to flow into said space to thereby lower the pressure of said fluid at said material output portion relative to the pressure at said material inlet portion, the diameter of said first tube being smaller than the diameter of said second tube; and wherein the reservoir, first tube and second tube have relative locations to be axially aligned.
- 2. A method of excavating material from one location to another location, the method including the steps of:
- providing a suctioning device;
- the suctioning device comprising a cylindrical reservoir having a fluid inlet tube, the reservoir for receiving pressurized fluid; a first tube connected to said reservoir, said first tube having a material inlet portion, a central portion and a material outlet portion, said central portion of said first tube being located within and in parallel spaced relationship to said reservoir; a second tube, said second tube having an open end located axially opposed to the reservoir and a connection end operably connected to said reservoir, said second tube surrounding substantially 1/3 of the length of said material outlet portion of said first tube and thereby forming an elongated space between said second tube and said material outlet portion of said first tube; a means coupling said reservoir and said space to permit a fluid output of said reservoir to flow into said space to thereby lower the pressure of said fluid at said material output portion relative to the pressure at said material inlet portion, the diameter of said first tube being smaller than the diameter of said second tube; and wherein the reservoir, first tube and second tube have relative locations to be axially aligned;
- orienting the material inlet portion of the first tube towards the material to be excavated; and,
- orienting the open end of the second tube in the location of desired material deposit.
