Humes worked closely with Telstra to develop a comprehensive range of precast communication pits suitable for the joining of cables in expansive and reactive soils.
Cable jointing access chambers
These chambers allow workers to enter the unit for cable installation and maintenance. There are three models available which vary in size from a length of 1,610 mm to 4,365 mm, a width of 1,260 mm to 1,560 mm, and a height of 1,058 mm to 1,864 mm.
Cable jointing pits
These pits permit cable jointing to be carried out externally. There are two pit models available; the J8 which measures 1,429 mm long, 619 mm wide, and 948 mm high, or the J9 model which measures 2,250 mm long, 710 mm wide and 975 mm high.
Costello pits
These circular precast shafts have a precast base and knockouts for the jointing of cables. Shaft and base sections can be manufactured with preformed block out locations to enable greater efficiencies when installing.
The costello pits are supplied in 1,050mm, 1,200mm, and 1,500mm diameter and come in different heights with risers to suit local requirements. Costello pits are approved by RailCorp (NSW).
Light pole bases
Light pole bases are placed in the ground to support and resist the forces produced by the column/post/shaft and can be used for both main roads or minor roads (residential/estates). Humes bases have been designed and developed in collaboration with Energex (QLD).
Conduits can be cast into the bases to provide a clear path for electrical cables.
Pad-mounted Uniculvert® modules
These Uniculvert® modules, which feature removable side panels have been designed in collaboration with Energex (QLD) to house electrical cables, and provide a solid mount for the electrical transformer.
The standard module is 1,400 mm long, 1,400 mm wide and 1,080 mm high. An optional base pad (2,000 mm by 1,700 mm) can be supplied when required.
Oil separators
Designed to capture oil in the event of a transformer or substation failure, and prevent its release into the environment. The tanks capture flows from bunded areas and contain the waste material until it can be removed by a licensed waste transporter.
Tank sizes are usually DN1950 or DN2400 of varying lengths (oil holding capacity).
