An adjustable in-ground box assembly is configured to form a protective enclosure for an in-ground utilities device. The adjustable in-ground box assembly includes an outer box and an inner box. A reinforced vertical interior fastener panel is formed with a wall of the outer box, and includes a number of pre-formed outer box fastener holes arranged in spaced apart vertical columns. The inner box includes a number of inner box fastener holes arranged in a horizontal row. The height of the in-ground box assembly is vertically adjusted by aligning the inner box fastener holes with horizontally-situated outer box fastener holes at a selected height on the vertical fastener panel. The tilt of the in-ground box assembly is adjusted by aligning the inner box fastener holes with selected diagonally-situated outer box fastener holes.

A meter pit tile extension assembly is provided. Illustratively, an inner ring is attachable to a pit tile. The inner ring includes a first set of a plurality of outwardly extending ribs. A first space located adjacent the first set of the plurality of outwardly extending ribs. An outer ring is provided that is telescopingly positioned over, and vertically movable with respect to, the inner ring. The outer ring includes a first set of a plurality of inwardly extending ribs. The first set of the plurality of inwardly extending ribs of the outer ring are selectively positionable in a first position in the first space between the first set of the plurality of outwardly extending ribs. The outer ring is also rotatable with respect to the inner ring. Rotation of the outer ring with respect to the inner ring causes the first set of the plurality of inwardly extending ribs to be selectively positionable in a second position such that at least one inwardly extending rib of the first set of the plurality of inwardly extending ribs is selectively positionable adjacent at least one outwardly extending rib of the first set of the plurality of outwardly extending ribs.

The present disclosure relates to a manhole with a manhole cover that can be adjusted in height and inclination in the entire structure. A manhole with a height/inclination-adjustable manhole cover includes: a manhole cover; a cover base closing the top of the manhole cover and having a pipe shape; a support having a pipe shape and radially overlapping the cover base; and an insertion disposed between the cover base and the support in the radial direction of the cover base and preventing movement of the cover base relative to the support through a wedge effect.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A meter pit tile extension assembly is provided. Illustratively, an inner ring is attachable to a pit tile. The inner ring includes a first set of a plurality of outwardly extending ribs. A first space located adjacent the first set of the plurality of outwardly extending ribs. An outer ring is provided that is telescopingly positioned over, and vertically movable with respect to, the inner ring. The outer ring includes a first set of a plurality of inwardly extending ribs. The first set of the plurality of inwardly extending ribs of the outer ring are selectively positionable in a first position in the first space between the first set of the plurality of outwardly extending ribs. The outer ring is also rotatable with respect to the inner ring. Rotation of the outer ring with respect to the inner ring causes the first set of the plurality of inwardly extending ribs to be selectively positionable in a second position such that at least one inwardly extending rib of the first set of the plurality of inwardly extending ribs is selectively positionable adjacent at least one outwardly extending rib of the first set of the plurality of outwardly extending ribs.

A riser section having a generally tapered, e.g., frustoconical wall, the riser section having a first connector assembly at one end of the riser section and a second connector assembly at the other end of the riser section.

A method for constructing an assembled recyclable rectangular working well with preset detachable door openings comprises steps of: (I) designing according to functional requirements for a rectangular working well; (II) constructing by supporting piles; (III) installing prefabricated top beam; (IV) edge protection construction; (V) alternate construction of earthwork excavation, retaining slabs and internal support breast beams; (VI) installing the ladder entering the rectangular working well; (VII) rectangular working well back cover; (VIII) demolition of the detachable subsection support piles in the door part and completing the construction of the assembled recyclable rectangular working well in the preset detachable door hole; (IX) after the operation in the well is completed, during the backfilling process of the rectangular working well, gradually recovering the working well components such as the retaining slab, the internal support girder, the prefabricated crown beam and the supporting piles.

A pit and an extension, each having flanges extending perpendicular to an axis of the pit and extension. The pit includes holes extending outwardly in the wall of the pit, preferably these holes are located at one end of the pit. Surfaces of the flanges are configured to mate together and clips secure the flanges together to inhibit movement apart of the pit and extension along the axis. In certain embodiments, the extension includes support ribs which may be both interior and exterior and the extension narrows from its flange towards an opposite end thereof.

A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus.

A riser section having a generally tapered, e.g., frustoconical wall, the riser section having a first connector assembly at one end of the riser section and a second connector assembly at the other end of the riser section.
