Abstract
A manhole device and corresponding system including a manhole is described. The manhole device comprises a main body having an upper portion, a lower portion and a securing means. The securing means is engageable with the manhole such that when secured to the manhole, the upper portion protrudes above a surface level and the lower portion is retained below the surface level in the manhole. The main body provides means for alignment for construction around the manhole while providing a barrier to prevent access to vehicles, people and debris during the construction process. A method of construction is also provided.
Claims15
A manhole device, comprising:
- a single-piece main body comprising an upper portion, a lower portion and a securing means;
- wherein:
- said securing means is engageable with a manhole to secure said single-piece main body in said manhole, such that, when secured to said manhole, said upper portion protrudes above a surface level and said lower portion is retained below said surface level in said manhole,
- said single-piece main body is configured to provide alignment means to maintain a diameter or dimension of an opening of said manhole, said opening providing access to an underground vault,
- said single-piece main body is further configured to position and align construction materials around said manhole,
- said single-piece main body further comprises an outer wall defining an internal space and a top surface, said top surface extending from an edge of said outer wall to cover said internal space, said top surface thereby preventing access into said internal space and providing a barrier so as to prevent access to said manhole during construction, and
- said single-piece main body comprises at least one slot in said outer wall;
- and
- a grating device comprising at least one support bracket for being received into said at least one slot, wherein at least part of said upper portion is removable to provide access for said grating device.

A manhole system comprising a manhole and a manhole device, said manhole device comprising:
- a single-piece main body comprising an upper portion and a lower portion, said single-piece main body being positioned in said manhole;
- wherein:
- said upper portion protrudes above a surface level,
- said lower portion comprises a securing means configured to retain said lower portion below said surface level and in said manhole,
- said single-piece main body provides alignment means to maintain a diameter or dimension of an opening of said manhole, said opening providing access to an underground vault,
- said single-piece main body being further configured to position and align construction materials around said manhole,
- said single-piece main body further comprises an outer wall defining an internal space and a top surface, said top surface extending from an edge of said outer wall to cover said internal space, said top surface thereby preventing access into said internal space and providing a barrier so as to prevent access to said manhole during construction, and
- said single-piece main body comprises at least one slot in said outer wall;
- and
- a grating device comprising at least one support bracket for being received into said at least one slot, wherein at least part of said upper portion is removable to provide access for said grating device.

A method of constructing a manhole, comprising the steps of:
- obtaining a manhole device having a single-piece main body comprising an upper portion, a lower portion and a securing means, wherein at least part of said upper portion is removable to provide access for a grating device;
- positioning said manhole device in said manhole such that said upper portion protrudes above a surface level and said lower portion is retained below said surface level in said manhole;
- engaging said securing means with said manhole to secure said manhole device in position;
- providing an alignment means to maintain a diameter or dimension of an opening of said manhole, said opening providing access to an underground vault, and said single-piece main body being further configured to position and align construction materials around said manhole by means of said single-piece main body;
- preventing access to said manhole during construction by providing a barrier by means of an outer wall defining an internal space and a top surface, said top surface extending from an edge of said outer wall to cover said internal space, said top surface thereby preventing access into said internal space of said single-piece main body;
- and
- disposing at least one support bracket of said grating device in at least one slot in said outer wall.
