The Vanstone Octa-Manhole is a large underground switching and routing chamber. Its purpose is to enable the ordering of underground services in a busy and congested environment. It can be used for data or electrical cables, fibre-optic ducts, feeders, or smaller diameter pipes. It was extensively used at Vodacom’s switchyard in Midrand. It is ideal for office parks, commercial and industrial centres, airports and more.
The Vanstone Octa-Manhole is equipped with 32 off 130mm diameter knock-out type entry holes in eight directions around the octagonal shape. It is of 3-piece design: Base or floor, ring walls and roof slab with lid. Shown here is a hinged cast iron lockable lid and frame that is cast into the roof slab. Any type of lid and frame may be used from heavy duty reinforced concrete to remotely-locked GRP. It is up to the Customer.
Installation is quick and easy: Excavate, level, put down the floor, then the ring-walls and lastly the roof slab. Seal as required and it’s done. A subsoil drain may be added underneath or around the chamber.
