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.

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.
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.
