Abstract
In a method for treating soil at a work site, a first pressure application tool is connected to a base unit and moved relative thereto along a first area of the work site adjacent a structure and operated to inject soil treatment down into the soil along the first area of the work site. A second pressure application tool is interchanged with the first pressure application tool and moved relative to the base unit along a second area of the work site adjacent the structure and different from the first area of the work site. The second pressure application tool is operated to apply soil treatment to the soil along the second area of the work site.
Claims20
A method of treating soil adjacent a structure at a work site using an apparatus including a first pressure injection tool, a second pressure application tool, and a fluid delivery device, said method comprising:
- moving the first pressure injection tool along a first area of the work site adjacent the structure, wherein the first pressure injection tool is in fluid communication with the fluid delivery device in a first pressure mode of the apparatus;
- operating the first pressure injection tool with the apparatus in the first pressure mode to inject soil treatment down into the soil along said first area of the work site;
- switching the apparatus between the first pressure mode and a second pressure mode, wherein, in the second pressure mode of the apparatus, the second pressure application tool is in fluid communication with the fluid delivery device and the first pressure injection tool is disconnected from the fluid delivery device;
- moving the second pressure application tool along a second area of the work site adjacent the structure;
- and
- operating the second pressure application tool with the apparatus in the second pressure mode to apply soil treatment to the soil along the second area of the work site.
A method of treating soil adjacent a structure at a work site using an apparatus including a first pressure injection tool, a second pressure application tool, and a fluid delivery device, said method comprising:
- connecting the first pressure injection tool to the fluid delivery device in fluid communication therewith such that the first pressure injection tool is positionable relative to the fluid delivery device;
- operating the fluid delivery device with the apparatus in a first pressure mode to deliver fluid at a first pressure to the first pressure injection apparatus, wherein the first pressure injection tool is in fluid communication with the fluid delivery device in a first pressure mode of the apparatus;
- injecting soil treatment down into the soil from the first pressure injection tool;
- disconnecting the first pressure injection tool from the fluid delivery device;
- connecting a second pressure application tool to the fluid delivery device in fluid communication therewith such that the second pressure application tool is positionable relative to the fluid delivery device;
- operating the fluid delivery device with the apparatus in a second pressure mode to deliver fluid to the second pressure application tool at a pressure substantially lower than the first pressure of the fluid delivered to the first pressure injection in the first pressure mode of the apparatus, wherein, in the second pressure mode of the apparatus, the second pressure application tool is in fluid communication with the fluid delivery device and the first pressure injection tool is disconnected from the fluid delivery device;
- and
- applying fluid to a surface of the soil from the second pressure application tool.
