Abstract
An apparatus is for use with a hydrovac truck having a vacuum assembly for connection to a holding tank, with a water supply configured to provide pressurized flowing water. Apparatus includes an elongated hollow assembly configured to be fluidly connectable with the vacuum assembly. A water jet assembly is mounted to the elongated hollow assembly. The water jet assembly is configured to be fluidly connectable with the water supply, so that the water jet assembly ejects pressurized flowing water toward the soil. Pressurized flowing water cuts into the soil, and urges formation of a slurry. Pressurized flowing water moves the water jet assembly along a circular path outlined by a cross-section of the elongated hollow assembly in the soil while the elongated hollow assembly and the water jet assembly move deeper into the soil. The vacuum assembly moves the slurry along the elongated hollow assembly and toward the holding tank.
Description
APPARATUS FOR USE WITH HYDROVAC TRUCK
TECHNICAL FIELD
[0001] This document relates to the technical field of (and is not limited to) an apparatus for use with a hydrovac truck (and method therefor).
BACKGROUND
TECHNICAL FIELD
[0001] This document relates to the technical field of (and is not limited to) an apparatus for use with a hydrovac truck (and method therefor).
BACKGROUND
[0002] A hydrovac truck (also called a suction excavator or a vacuum excavator) is a construction vehicle configured to remove materials (soil) from a hole on land or remove heavy debris from land. The hydrovac truck is configured to produce powerful suction through a suction hose. The suction hose may have two handles for the operator to hold. The handles may be on a collar which can be rotated to uncover suction-release openings (with grilles over) to release the suction to make the suction nozzle drop anything which it has picked up and is too big to go up the tube.
The end of the tube may be toothed. This helps to cut earth when used for excavating;
however, when it is used to suck up loose debris and litter, some types of debris items may snag on the teeth. The earth to be sucked out may be loosened first with a compressed-air lance or a powerful water jet. Excavating with the hydrovac truck may be called vacuum excavation or hydro excavation if a water jet is used. Vacuum excavation (also known as suction excavation) is considered a best practice for safely finding and seeing underground utilities, reducing by more than half the chance of damaging buried utilities.

Vacuum excavation (also known as suction excavation) is considered a best practice for safely finding and seeing underground utilities, reducing by more than half the chance of damaging buried utilities.
SUMMARY
[0003] It will be appreciated that there exists a need to mitigate (at least in part) at least one problem associated with the existing hydrovac trucks (also called the existing technology). After much study of the known systems and methods with experimentation, an understanding of the problem and its solution has been identified and is articulated as follows:
[0004] To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a major aspect) an apparatus. The apparatus is for use with a hydrovac truck having a vacuum assembly for connection to a holding tank, with a water supply configured to provide pressurized flowing water.
The apparatus includes an elongated hollow assembly that is movable along a longitudinal axis of the elongated hollow assembly. The elongated hollow assembly is configured to be fluidly connectable with the vacuum assembly. A water jet assembly is mounted to the elongated hollow assembly. The water jet assembly is configured to be fluidly connectable with the water supply. This is done in such a way that the water supply, in use, provides the pressurized flowing water to the water jet assembly, and the water jet assembly, in use, ejects the pressurized flowing water, which was received from the water supply, toward the soil. The pressurized flowing water, which was ejected from the water jet assembly toward the soil, cuts, in use, into the soil being positioned proximate to the water jet assembly, and urges, in use, the formation of a slurry having mixed water and soil positioned. The slurry is proximate to the water jet assembly with the slurry positioned, at least in part, within the elongated hollow assembly. In addition, the pressurized flowing water, which was ejected from the water jet assembly toward the soil, moves, in use, the water jet assembly along a circular path outlined by a cross-section of the elongated hollow assembly in the soil while the elongated hollow assembly and the water jet assembly move deeper into the soil. The vacuum assembly, in use, moves the slurry having mixed water and soil away from the water jet assembly along the elongated hollow assembly and toward the holding tank.

[0021] More specifically, the apparatus 100 is for use with the hydrovac truck 900 having a vacuum assembly 902 for connection to a holding tank 904, with a water supply 906 configured to provide pressurized flowing water.
[0022] The apparatus 100 includes a synergistic combination of an elongated hollow assembly 102 and a water jet assembly 106.
[0023] The elongated hollow assembly 102 is movable along a longitudinal axis 104 of the elongated hollow assembly 102. The elongated hollow assembly 102 is configured to be fluidly connectable (either directly or indirectly) with the vacuum assembly 902.

[0024] The water jet assembly 106 is mounted to the elongated hollow assembly 102.
Specifically, the water jet assembly 106 is mounted to the second end 202 of the elongated hollow assembly 102. The water jet assembly 106 is configured to be fluidly connectable (either directly or indirectly) with the water supply 906. This is done in such a way that the water supply 906, in use, provides the pressurized flowing water to the water jet assembly 106 (as depicted in FIG. 1). In addition, the water jet assembly 106, in use, ejects the pressurized flowing water, which was received from the water supply 906, toward the soil (as depicted in FIG. 4 and FIG. 5). In addition, the pressurized flowing water, which was ejected from the water jet assembly 106 toward the soil, cuts, in use, into the soil being positioned proximate to the water jet assembly 106, and urges, in use, the formation of a slurry 204 having mixed water and soil. The slurry 204 is positioned proximate to the water jet assembly 106 (as depicted in FIG. 4 and FIG.
5), with the slurry 204 positioned, at least in part, within the elongated hollow assembly 102. In addition, the pressurized flowing water, which was ejected from the water jet assembly 106 toward the soil, moves (rotates), in use, the water jet assembly 106 along a circular path (as depicted in FIG. 2) that is outlined by a cross-section of the elongated hollow assembly 102 in the soil while the elongated hollow assembly 102 and the water jet assembly 106 move deeper into the soil (as depicted in FIG. 5). In addition, the vacuum assembly 902, in use, moves the slurry 204 having mixed water and soil away from the water jet assembly 106 along the elongated hollow assembly 102 and toward the holding tank 904 (as depicted in FIG. 4 and FIG. 6).

In addition, the water jet assembly 106, in use, ejects the pressurized flowing water, which was received from the water supply 906, toward the soil (as depicted in FIG. 4 and FIG. 5). In addition, the pressurized flowing water, which was ejected from the water jet assembly 106 toward the soil, cuts, in use, into the soil being positioned proximate to the water jet assembly 106, and urges, in use, the formation of a slurry 204 having mixed water and soil. The slurry 204 is positioned proximate to the water jet assembly 106 (as depicted in FIG. 4 and FIG.
5), with the slurry 204 positioned, at least in part, within the elongated hollow assembly 102. In addition, the pressurized flowing water, which was ejected from the water jet assembly 106 toward the soil, moves (rotates), in use, the water jet assembly 106 along a circular path (as depicted in FIG. 2) that is outlined by a cross-section of the elongated hollow assembly 102 in the soil while the elongated hollow assembly 102 and the water jet assembly 106 move deeper into the soil (as depicted in FIG. 5). In addition, the vacuum assembly 902, in use, moves the slurry 204 having mixed water and soil away from the water jet assembly 106 along the elongated hollow assembly 102 and toward the holding tank 904 (as depicted in FIG. 4 and FIG. 6).
[0025] In view of the foregoing, there is provided a method of operating the hydrovac truck 900. The method includes (and is not limited to) a synergistic combination of operation (A), operation (B), operation (C), operation (D) and operation (E).
[0026] Operation (A) includes fluidly connecting (either directly or indirectly) the elongated hollow assembly 102 with the vacuum assembly 902. The elongated hollow assembly 102 is movable along the longitudinal axis 104 of the elongated hollow assembly 102.
[0027] Operation (B) includes fluidly connecting (either directly or indirectly) the water jet assembly 106 with the water supply 906. The water jet assembly 106 is mounted to the elongated hollow assembly 102.
[0028] Operation (C) includes providing the pressurized flowing water via the water supply 906 to the water jet assembly 106.
[0029] Operation (D) includes ejecting, via the water jet assembly 106, the pressurized flowing water, which was received from the water supply 906, toward the soil.
This is done in such way that the pressurized flowing water that is ejected from the water jet assembly 106 toward the soil: (a) cuts into the soil being positioned proximate to the water jet assembly 106, (b) urges formation of a slurry 204 having mixed water and soil positioned proximate to the water jet assembly 106 with the slurry 204 being positioned, at least in part, within the elongated hollow assembly 102, and (c) moves (rotates) the water jet assembly 106 along a circular path that is outlined by a cross-section of the elongated hollow assembly 102 in the soil while the elongated hollow assembly and the water jet assembly 106 move deeper into the soil.

[0031] In summary, the apparatus 100 is configured, in use, to form a hole (also called, a pile hole) in the ground by making use of a pressurized flow of water (for formation of the hole in the ground) and making use of powered suction (for soil and water removal).
Preferably, the hole that was formed by the apparatus 100 forms a straight pile hole. A

[0042] Referring to the embodiment as depicted in FIG. 4 and 30, the water jet assembly 106 is configured to eject, in use, the pressurized flowing water toward the soil. This is done in such a way that the pressurized flowing water that is ejected from the water jet assembly 106, in use, urges the relatively rotatable hollow tube assembly 112 to rotate while the relatively stationary hollow tube assembly 108 remains stationary.
In addition, the pressurized flowing water that is ejected from the water jet assembly 106, in use, loosens a portion of the soil positioned proximate to the perimeter of the second end section 116. In addition, the pressurized flowing water that is ejected from the water jet assembly 106, in use, mixes the soil that is loosened with the pressurized flowing water to form the slurry 204 having mixed water and soil.
