DETAILED DESCRIPTION OF THE INVENTION

(5) While this invention is susceptible of embodiment in many different forms, there is shown in the drawings, and will herein be described hereinafter in detail, some specific embodiments of the invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments so described.

(6) A storage vessel 100 includes a body 102 that has two or more internal chambers or sections, a bulkhead 108 within the body 102 of the storage vessel 100 to separate the sections, and a roll off attachment apparatus. The internal sections include a fluid section 104 and a debris section 106. The fluid section 104 holds a fluid for use in hydroexcavation. The debris section 106 holds excavated debris from an excavation site. The bulkhead 108 is connected to the body 102 of the storage vessel 100 and separates the debris and excavation fluid stored in the storage vessel 100. The storage vessel 100 also comprises a series of ports and hatches to provide access to the fluid and debris stored within the storage vessel 100. The bulkhead 108 may be angled to promote debris to drain from the debris section 106. The storage vessel 100 can be moved to and from excavation sites using the roll off attachment apparatus which allows the storage vessel 100 to be attached to or lifted onto a truck.

(7) Additional sections and bulkheads may be necessary where different excavation fluids are required for a hydroexcavation job. Additional sections may also be needed where it is necessary to separate debris from hydroexcavation. In such cases, the additional bulkheads prevent mixing of fluids stored in the sections of the storage vessel 100.

(8) Referring now to FIGS. 1 and 2, shown therein are perspective views of a storage vessel 100 constructed in accordance with an exemplary embodiment of the invention. In this embodiment, the storage vessel 100 has a body 102, a fluid section 104, a debris section 106, and a bulkhead 108. The body 102 of the storage vessel supports the storage vessel sections 104, 106 and the bulkhead 108. Ports, drains, and hatches are integrated into the body 102 to provide access to the fluid and debris which may be stored within the storage vessel 100.

(9) The body 102 is constructed of steel or other rigid metal materials. The body 102 may be coated in a paint or sealant to prevent corrosion. The body 102 has a front panel 110, a back panel 112, a left panel 114, a right panel 116, a top panel 118, and a bottom panel 120 connected in a cuboid shape. It will be understood that in other embodiments the storage vessel may be constructed in other shapes such as a cylinder. In this exemplary embodiment, the panels are constructed together as one unitary piece; however, the invention is not so limited and in other embodiments portions of the body 102 may be removable or may open on a hinge to provide access to the sections of the storage vessel 100.

(10) The fluid section 104 is positioned between the front panel 110 and the bulkhead 108. The fluid section 104 is configured to store excavation fluid 152 for use in a hydroexcavator. The fluid section 104 has a fluid fill port 122 configured to allow the fluid section 104 to be filled with excavation fluids 152, such as water. The storage vessel 100 also has a fluid load port 124. The fluid load port 124 provides a hydroexcavator with access to the excavation fluid 154 within the fluid section 104. The fluid load port 124 extends vertically downward into the fluid section 104. The vertical extension of the fluid load port 124 into the fluid section 104 allows a hydroexcavator to withdraw excavation fluid 154 from the bottom of the fluid section 104. In the exemplary embodiment the fluid fill port 122 and fluid load port 124 are integrated into the portion of the top panel 118 covering the fluid section 104 of the storage vessel 100. The fluid fill port 122 and fluid load port 124 may be integrated into other portions of the body 102 and the fluid load port 124 may not extend into the fluid section 104. In some embodiments, the fluid load port 124 and the fluid fill port 122 or other combinations of ports may be integrated into a single port.

(11) In the exemplary embodiment shown in FIG. 1, the debris section 106 is positioned between the back panel 112 and the bulkhead 108. The debris section 106 is configured to store debris (not shown) that has been excavated with a hydroexcavator. The debris section 106 has a debris load port 126 which is configured to allow debris, such as mud, to flow from a hydroexcavator through the debris load port 126 and into the debris section. As illustrated, the debris load port 126 is integrated into the portion of the top panel 118 covering the debris section 106 of the storage vessel 100. The debris section 106 also has a drain port 128 and a skim port 130. The drain port 128 and skim port 130 are configured to allow debris to flow out of the debris section of the storage vessel through the ports 128, 130. To accommodate large debris which may have accumulated in the debris section 106, the drain port 128 may have a larger diameter than other ports integrated into the storage vessel 100. The portion of the bottom panel 120 located below the debris section 106 may be sloped toward the drain port 128 to promote the flow of debris to the drain port 128 when emptying the debris section 106.

(12) The skim port 130 is positioned above the drain port 128. Debris from hydroexcavation stored within the debris section 106 may separate into layers. As shown in FIG. 3, debris may separate into a first debris layer 150 and a second debris layer 152 within the debris section 106. The skim port 130 allows the top or first debris layer 150 to be removed while leaving the bottom or second debris layer 152 within the debris section 106. The separation of the layers allows first and second layers 150, 152 to be independently removed or separately repurposed. Turning back to FIGS. 1 and 2, the drain port 128 and the skim port 130 are exemplified as integrated into the back panel 112. In other embodiments, the drain port 128 and skim port 130 may be integrated into other portions of the debris section 106 if the skim port 130 is located at a higher position than the drain port 128. In other embodiments, the storage vessel 100 may not include a skim port 130. To promote the emptying of debris from the debris section 106, the drain port 128 may be integrated into the body horizontally on the bottom panel 120 or may be integrated into the body at the lowest vertical position of the debris section 106.

(13) The fluid section 104 may have a fluid section hatch 132 and the debris section 106 may have a debris section hatch 132. The hatches 132, 134 are integrated into the portions of the top panel 118 covering the respective section 104, 106. The hatches 132, 134 are configured to allow an operator to access the internal portion of the section 104, 106 through the hatch 132, 134. The hatches 132, 134 are generally sized larger than the ports integrated into the body 102 of the storage vessel 100. The larger sized hatch 132, 134 allows an operator to visually inspect the contents of the section 104, 106 and operate tools inside the section 104, 106 such as tools for cleaning the interior of the section 104, 106. In other embodiments fewer or additional hatches may be integrated into the body 102. In the illustrated embodiment, a ladder 136 is attached to the right panel 116. The ladder 136 would allow an operator to access the hatches and ports located on the top panel 118. The hatches and ports integrated into the body 102 may be opened or closed to access the sections 104, 106. The ports described herein may be configured with an attachment mechanism, such as a threaded collar to allow fluid or debris lines from a hydroexcavator to be quickly and easily attached to the ports. It will be understood that in other embodiments additional or fewer ports and hatches may be integrated into the body 102.

(14) The storage vessel 100 has a roll off attachment apparatus 138 integrated into the front panel 110 and four wheels 140 attached to the bottom panel 120. The wheels 140 may be attached to a skid connected to the bottom panel 120. A cabled lift mechanism such wench and hydraulic lift incorporated into a motorized vehicle such as a truck (not shown) can be attached to the roll off attachment apparatus 110. The attached cabled lift mechanism can then be used to lift the storage vessel 100 onto the motorized vehicle for transportation. The wheels 140 attached to the bottom panel 120 decrease the load on the cabled lift mechanism and prevent damage to the bottom panel 120 when loading the storage vessel 100 onto the motorized vehicle. The wheels 140 also provide stable footing for the storage vessel 100 when it is dropped at an excavation site. It will be understood that in other embodiments the storage vessel 100 may be attached to a motorized vehicle with other sufficient attachment means such as a fifth wheel coupling.

(15) Turning to FIG. 3 a cross-sectional side view of the storage vessel 100 of FIGS. 1 and 2 is shown. The storage vessel 100 contains an excavation fluid 154 contained within the fluid section 104 and a first 150 and second debris layer 152 contained within the debris section 106. The debris 150, 152 and the excavation fluid 154 are separated by the angled bulkhead 108. The cross-sectional view shows the angle of the bulkhead 108 within the storage vessel 100. The bulkhead 108 is sloped toward the drain port 128 to promote the flow of debris toward the drain port 128 when the debris section 106 is emptied. In other embodiments the bulkhead 108 and section of the bottom panel 120 under the debris section 106 may both be sloped to promote the flow of debris toward the drain port 128. The cross-sectional view also shows the extension of the fluid load port 124 into the fluid section 104. As described above the vertical extension of the fluid load port 124 into the fluid section 104 allows a hydroexcavator to withdraw excavation fluid 154 from the bottom of the fluid section 104.
