Abstract
A system to manufacture a native soil flowable fill onsite includes hydro excavation equipment having a suction hose. In addition, the system includes a plurality of onsite debris tanks, where each onsite debris tank is configured to be coupled separately to the suction hose and to store native soil vacuumed from an adjacent hole at an onsite excavation. The system also includes a mixing apparatus inside each of the onsite debris tanks configured to mix the native soil from the adjacent hole with additional components to form a native soil flowable fill for the respective adjacent hole.
Claims12
A method to manufacture a native soil flowable fill onsite, the method comprising:
- connecting excavation equipment to a first onsite debris tank;
- hydro excavating native soil with the excavation equipment to form a first hole at a first excavation;
- transferring the native soil to the first onsite debris tank adjacent to the first hole using the excavation equipment;
- disconnecting the excavation equipment from the first onsite debris tank;
- moving the excavation equipment to a second onsite debris tank;
- connecting the excavation equipment to the second onsite debris tank;
- hydro excavating native soil with the excavation equipment to form a second hole at a second excavation;
- transferring the native soil to the second onsite debris tank adjacent to the second hole using the excavation equipment;
- adding a pozzolan component, cement and water to the respective first and second onsite debris tank adjacent to the respective hole;
- mixing the native soil in the respective first and second onsite debris tank adjacent to the respective first and second hole to form a liquid comprising the native soil flowable fill;
- and
- transferring the native soil flowable fill back to the respective first and second hole from where the native soil was hydro excavated;
- wherein the liquid comprising the native soil flowable fill comprises a flowable state when transferring into the hole and after a desired period of time, the flowable state sets to a settable state.
A method to manufacture a native soil flowable fill onsite, the method comprising:
- removing native soil from a plurality of holes at an excavation;
- placing an onsite debris tank adjacent to each hole of the excavation;
- transferring the native soil from each of the plurality of holes directly to a respective onsite debris tank;
- mixing the native soil in the respective onsite debris tank to form a liquid comprising the native soil flowable fill using a mixing apparatus;
- and
- transferring the native soil flowable fill from the respective onsite debris tank to the adjacent hole;
- wherein the liquid comprising the native soil flowable fill comprises a flowable state when filling the first excavation, and after a desired period of time, the flowable state sets to a settable state.
