Abstract
The present disclosure provides an advantageous underground enclosure/assembly for housing electrical components. More particularly, the present disclosure provides an underground enclosure/assembly (e.g., handhole/pullbox assembly) that is configured to protect wiring connections and provide access to those connections for initial installation, and later for maintenance/alteration. The present disclosure provides for a cylindrical body and a frame with a lip feature to interface with the cylindrical body to enhance the durability and to assist in maintaining the circularity of the cylindrical body. The advantageous frame provides for a feature (e.g., a notch) to integrate fill materials with the frame. The frame further includes features for interfacing a cover.
Claims19
A handhole assembly comprising:
- a hollow cylindrical body including a base, a tapered side wall with a rim at the top, and a bottom wall, the cylindrical body having a larger diameter at the base than at the top for an inclined upward slope of the tapered side wall, wherein the top of the hollow cylindrical body is open ended;
- and
- a casting frame including a first hollow ring and a second hollow ring, wherein the first hollow ring is concentric with respect to the second hollow ring, and the first hollow ring includes a side wall with an outside diameter, a top edge, and a bottom surface;
- a lip cavity extending from the bottom surface of the first hollow ring towards the top edge, the lip cavity including a first lip wall, a second lip wall, and a lip cavity surface, the first lip wall and second lip wall extend from the lip cavity surface to form the lip cavity, wherein the first lip wall forms an outside diameter of the lip cavity and the second lip wall forms an inside diameter of the lip cavity;
- wherein the second hollow ring extends from the bottom surface of the first hollow ring, the second hollow ring including a side wall with an outside diameter, and a bottom edge, and the outside diameter is smaller than the outside diameter formed by the first lip wall;
- wherein the casting frame is mounted with respect to the cylindrical body, the lip cavity of the casting frame is mounted with respect to the top edge of the cylindrical body and the first lip wall and the second lip wall extend past the top edge of the cylindrical body towards the base, and the second hollow ring extends within the cylindrical body towards the base;
- wherein the side wall of the first hollow ring further includes a notch extending inward from the outside diameter, wherein the notch enables media interaction with the casting frame.
A handhole assembly comprising:
- a hollow cylindrical body including a base, a tapered side wall with a rim at the top and at least one rib mounted with respect thereto, and a bottom wall, the cylindrical body having a larger diameter at the base than at the top for an inclined upward slope of the tapered side wall, wherein the top of the hollow cylindrical body is open ended;
- a casting frame including a first hollow ring and a second hollow ring, wherein the first hollow ring is concentric with respect to the second hollow ring, and the first hollow ring includes a side wall with an outside diameter, a top edge, and a bottom surface;
- and
- a lip cavity extending from the bottom surface of the first hollow ring towards the top edge, the lip cavity including a first lip wall, a second lip wall, and a lip cavity surface, the first lip wall and second lip wall extend from the lip cavity surface to form the lip cavity, wherein the first lip wall forms an outside diameter of the lip cavity and the second lip wall forms an inside diameter of the lip cavity;
- wherein the second lip wall extends beyond the bottom surface to form a side wall of the second hollow ring, the side wall of the second hollow ring having an outside diameter and a bottom edge, wherein the side wall of the second hollow ring is inwardly tapered;
- wherein the casting frame is mounted with respect to the cylindrical body, the lip cavity of the casting frame is mounted with respect to the top edge of the cylindrical body and the first lip wall and the second lip wall extend past the top edge of the cylindrical body towards the base, and the second hollow ring extends within the cylindrical body towards the base;
- and
- wherein the side wall of the first hollow ring includes a notch perpendicularly cut into the side wall of the first hollow ring.
