Abstract

A movable steam vent system is provided. The system includes a base and at least one pipe member. The base includes a tapered outer surface defined by an outer wall, a frustoconical inner surface defined by an inner wall, a plurality of ribs extending from the inner surface, the inner wall and the outer wall defining a space therebetween, the base further having an opening in an upper surface, the opening having a slot therein, the opening being in fluid communication with a hollow interior defined by the inner wall, the inner wall having an end that is sized to cover the subsurface space opening. The at least one pipe member is removably coupled to the base, the at least one pipe member having a having an outer wall, an inner wall, the inner wall defining a hollow interior that is in fluid communication with the base hollow interior.

First claim

What is claimed is:

1. A movable steam vent system for an enclosed subsurface space having an opening, the system comprising:
a base portion having a tapered outer surface defined by an outer wall, a frustoconical inner surface defined by an inner wall, a plurality of ribs extending from the inner surface, the inner wall and the outer wall defining a space therebetween, the base portion further having an opening in an upper surface, the opening being defined by a wall having a slot therein, the opening being in fluid communication with a first hollow interior defined by the inner wall, the inner wall having an end that is sized to cover the subsurface space opening; and
at least one pipe member removably coupled by a rotational movement to the base portion, the at least one pipe member having a wall with an outer surface, and an inner surface, the pipe member inner surface defining a second hollow interior that is in fluid communication with the first hollow interior;
wherein the at least one pipe member includes a projection that extends from a first end, the projection being sized to fit within the base portion opening;
wherein the projection of the at least one pipe member includes a first tab, the first tab being positioned in the slot of the base portion when the at least one pipe member is coupled to the base portion;
wherein the first tab includes a semi-spherical outer surface with a curved outer edge and two adjoining sides.

2. The system of claim 1 , wherein the at least one pipe member includes a first pipe member and a second pipe member, the first pipe member being removably coupled to the base portion opening and the second pipe member being removably coupled to a second end of the first pipe portion opposite the base portion.

3. The system of claim 1 , wherein the slot of the base portion includes an arcuate surface with an end being coplanar with the base portion inner wall.

4. The system of claim 1 , wherein the projection includes a first channel and a second channel disposed on opposite sides of the first tab member.

5. The system of claim 4 , wherein first pipe member includes a first indicator element in the outer surface, the first indicator element being aligned with a centerline of the first pipe member.

6. The system of claim 5 , wherein the base portion includes a second indicator element in the outer surface adjacent the base portion opening, the second indicator element being aligned with and adjacent to the second slot when the first pipe portion is coupled to the base portion.

7. A system for venting steam from a manhole, the system comprising:
a base member including a flange on a first end, a curved outer wall, a conical inner surface defining a first interior portion, a frustoconical first opening in a second end opposite the first end, the first opening being defined by a wall having at least one slot and a bottom surface, and a hole extending between the first interior portion and the bottom surface, the flange being sized to cover an outer diameter of the manhole, wherein the curved outer wall and conical inner surface defining a hollow space therebetween; and
a first pipe member removably coupled by a rotational movement to the base member, the first pipe member having a wall and a second hollow interior portion defined by an inner surface of the wall, the first pipe member having a frustoconical first projection extending from a first end, the frustoconical first projection being sized to fit within the first opening, the projection having a first tab member sized to fit within the at least one slot when the first pipe member is coupled to the base member, the second interior portion being fluidly coupled to the first interior portion when the first pipe member is coupled to the base member;
wherein the first tab member includes a semi-spherical outer surface with a curved outer edge and two adjoining sides.

8. The system of claim 7 , wherein the first pipe member includes a second opening in a second end opposite the first end, the second opening having a wall extending toward the first end to define a third hollow interior portion, the second opening wall having a lip on an end.

9. The system of claim 8 , further comprising a second pipe member removably coupled to the first pipe member, the second pipe member includes a wall with an inner surface that defines a third interior portion, the second pipe member having a second projection extending from a first end, the second projection being sized to fit within the second opening.

10. The system of claim 9 , wherein:
the first pipe member includes a second slot in the second opening wall; and
the second pipe member includes a second tab extending from the second projection, the second tab being disposed in the second slot when the second pipe member is coupled to the first pipe member.

11. The system of claim 7 , wherein the base member further includes a plurality of ribs extending along the conical inner surface, the plurality of ribs being equally spaced about the periphery of the conical inner surface.

12. The system of claim 7 , wherein the first pipe member includes:
a first channel extending from the first end, the first channel being offset from a first side of the first tab; and
a second channel extending from the first end and arranged opposite the first tab from the first channel.

13. The system of claim 12 wherein the first pipe member includes a first indicator element on an outer surface of the wall, the first indicator element being aligned with the first channel.

14. The system of claim 13 , wherein the first pipe member includes a second indicator element on the outer surface of the wall, the second indicator being aligned with a centerline of the first pipe.

15. The system of claim 14 , wherein the first indicator and the second indicator are projections extending radially from the outer surface.

16. The system of claim 7 , wherein the base member is formed by rotational molding.

17. The system of claim 12 , wherein the first pipe member is formed by rotational molding.
