Device for use with measuring soil gas and method of use
Exemplary embodiments are directed to a device and method of use thereof for facilitating the analysis of samples of sub-slab soil gas that comprise an adapter body that includes, a first barbed portion, an external engaging portion, a threaded collar portion, a second barbed portion, and an internal cavity that axially passes through the length of the adapter body. The device may further include a tubular body with an interior cavity adapted to receive at least a portion of the second barbed portion of the adapter body to produce a mating engagement therebetween.
1. A device for facilitating the analysis of samples of a sub-slab soil gas, comprising:
an adaptor body, having an internal cavity axially passing therethrough, comprising:
a first barbed portion, said barbed portion having at least one barb situated at a proximal end of the adaptor body;
a second barbed portion that includes at least one barb and is located at the distal end of the adaptor body;
a threaded collar portion interposed between said first and second barbed portions, said threaded collar portion adapted to provide a surface for a tool to contact during installation and removal of the adaptor body, said tool including:
a stem having a first and second end, the first end having a pre-determined length of male threads located thereon, the second end intersecting with a handle;
an installation cavity disposed within an at least one end of said handle, said installation cavity adapted to receive said first barbed portion;
an extraction cavity disposed within the first end of said stem, said extraction cavity adapted to receive said first barbed portion; and
a tubular body with an interior cavity adapted to receive at least the second barbed portion of the adaptor body to produce a mating engagement therebetween.
2. The device of claim 1 , further comprising a raised end on the distal end of the adaptor body.
3. The device of claim 2 , wherein the raised end includes a chamfer that facilitates the insertion of the raised end within the inner cavity of the tubular body.
4. The device of claim 1 , further comprising an installation tool that is adapted to apply force on a portion of the adaptor body to effectuate installation of the adaptor body within a drilled core.
5. The device of claim 1 , wherein said tool is T-shaped.
6. The device of claim 1 , wherein said tool further comprises a coupling threaded onto said first end of said stem.
7. A system for facilitating the analysis of samples of a sub-slab soil gas, comprising:
a tool, said tool including:
a stem having a first and second end;
a threaded portion located on at said first end of said stem, said threaded portion having a predetermined length;
a handle intersecting with said stem at said second end;
an installation cavity disposed within an at least one end of said handle;
an extraction cavity disposed within said first end of said stem;
an adaptor body, said adaptor body including:
a first and second barbed portion joined by a threaded collar portion;
an internal cavity that axially passes through the length of the adaptor body; and
a tubular body with an interior cavity adapted to receive at least the second barbed portion of the adaptor body to produce a mating engagement therebetween.
8. The system of claim 7 , further comprising a coupling adapted to thread onto said threaded portion of said tool and said threaded collar of said adaptor body.
9. The system of claim 8 , wherein said threaded portion is adapted to engage said threaded collar of said adaptor body.
10. The system of claim 8 , wherein said tool is T-shaped.
11. The system of claim 8 , further comprising a high friction material, said high friction material used between the intersecting portions of the tubular body and the second barbed portion.
12. The system of claim 8 , wherein said installation cavity is adapted to receive said first barbed portion.
13. The system of claim 8 , wherein said extraction cavity is adapted to receive said first barbed portion.
14. The system of claim 8 , wherein rotational force of the tool is translated to an upward force on said adaptor body for extraction.
15. A method for collecting gas samples of sub-slab soil gas for analysis, comprising:
providing an adaptor body, said adaptor body comprising a first and second barbed portion and a threaded collar joining said first and second barbed portions;
providing a tool, said tool comprising a stem having a first and second end, a threaded portion located at the first end, a handle extending from said second end, an installation cavity disposed within an at least one end of said handle, and an extraction cavity disposed within said first end of said stem;
securing a tubular body around at least a portion of said second barbed portion;
placing at least a portion of said first barbed portion within said installation cavity in said tool;
striking said handle opposite said installation cavity in order to force said adaptor body and associated tubular body into a drilled core;
connecting a soil gas measurement device to said first barbed portion;
attaching the threaded portion of the first end to the thread collar of the adaptor body;
rotating said tool relative to said adaptor body in order to force said adaptor upward; and
inserting at least a portion of said first barbed portion into said extraction cavity.
16. The method of claim 15 , wherein said threaded portion of said first end is attached to the threaded collar by a coupling.
17. The method of claim 15 , wherein said threaded portion of said first end is threaded directly onto said threaded collar of said adaptor body.
18. The method of claim 15 , wherein said tool has a T-shape.
