A lid-lift hole assembly for an underground utility vault lid (78) comprises a liner (10, 50) positioned in an open-ended lid-lift hole (38, 80), and a receptacle (12, 66) positioned below the liner (10, 50). The receptacle (12, 66) has a bottom wall (22, 68) with upright side walls (24, 26) forming an upwardly facing open space (28, 76) within the receptacle (12, 66). Opposite side walls (24) of the receptacle contain thru-holes (32, 72) for receiving fasteners (30, 76). The thru-holes (32, 72) are aligned with fastener holes (34) in opposite side walls (16) of the liner (10, 50). Fasteners (30, 76) extending through the thru-holes (32, 72) and into the fastener holes (34) (from the underside of the lid (78)) are tightened (to apply pressure to the juncture between the receptacle (12, 66) and the liner (10, 50)) to lock the liner (10, 50) in the lid-lift hole (38, 80). The receptacle (12, 66) forms an enlarged-volume (44), box-like enclosure rigidly (but releasably) held beneath an open passage through the liner (10, 50). The space (28, 76) inside the receptacle (12, 66) can contain debris kept from entering the working area of the vault. The space (28, 76) inside the receptacle (12, 66) also is shaped to receive a tool for removing the lid (78). |
