Definitions

  • the present invention relates to a ducting chamber ring and module, a ducted chamber, a mould and a method of assembling a modular chamber system
  • Many domestic and civil services such as traffic signalling, street lighting, telecoms, fibre optics, gas, electricity and water supply are routed underground. Such services are connected through complex systems of interconnected ducts and chambers.
  • the ducts commonly housing pipes or insulated cables, run between the chambers, which allow collection and junctioning of the pipes or cables, or routing to the surface feature which they supply.
  • a known solution is rotor-moulded polyethylene modules, joined on their lateral sides to form a ring, the rings then stacked to create the required height of chamber.
  • the lateral joints consist of individual parts which are connected together by a double head and neck part which is hammered into a gap between two parts to retain them. In practice there are disadvantages arising from this arrangement. The number of parts in the lateral joint provides the opportunity for parts to go missing on site, or for inaccurate assembly, whereby the parts are not hammered in correctly or far enough.
  • the advised installation method is to dig a hole that is large enough so that an operator may enter into the hole and build up the chamber from the bottom, commonly a hole is dug which is big enough for the chamber, which is then assembled on the surface and subsequently lowered into the hole.
  • a hole is dug which is big enough for the chamber, which is then assembled on the surface and subsequently lowered into the hole.
  • a known solution for providing entry and exit points for the ducting is for holes to be cut in the module walls. However, this creates a zone of weakness, reducing the compressive strength of the module.
  • a ducting chamber ring or module for making the same, the ring or module being a hollow, injection moulded part, the ring or module defining an inner wall, an outer wall and a bore wall extending between said inner and outer walls and surrounding and defining a bore.
  • the bore wall which lines the bore provides strength to the walls of the ring or module, tying them together and providing a more rigid, strong structure.
  • the bore wall may be of any suitable shape, but in a preferred embodiment the bore is cylindrical in section. Having a lined cylindrical hole means that there is the strength of an arch over the top and strength from the whole cylinder throughout.
  • the bore may be spanned by a web, at least part of the web being removable to open the bore.
  • the web may have a line of weakness around the removable part of the web.
  • the line of weakness may be adjacent the bore wall or the line of weakness may be spaced from the bore wall. This arrangement allows the web or part of the web to be cut away easily to provide a line of communication between the inner and outer walls, such that a cable, for example, may be inserted through the module bore.
  • the web is substantially coplanar with one of said inner and outer walls. This arrangement allows for an easier manufacturing process for the module. Having the web substantially coplanar with either the inner and outer walls simplifies both the tool design and access for cutting the required hole.
  • the wall thickness is substantially uniform. Having the same wall thickness avoids possible complications in the manufacturing process such as unequal cooling of the material.
  • the ring or module may be made wholly or principally from plastics material, such as polypropylene. Where the ring or module is made principally from plastics material, the plastics material may be combined with a filler, such as talc.
  • the module or ring may be provided with a step iron. In another preferred embodiment the module or ring is provided with a cable clamp. In a preferred embodiment the module or ring is reinforced by ribs between said inner and outer walls. At least one of the ribs preferably intersects and is interrupted by the bore.
  • the module or ring is a structural component, and once buried underground it will need to support the static loading of any soil placed thereupon and any transient loading according to the use of the land directly above the site of its burial.
  • the provision of ribs between the walls greatly increases its strength in compression, furthermore, providing ribs intersecting with the bore wall prevents obvious areas of weakness being created.
  • the bore has constant diameter. The bore diameter may be 64mm or 114mm.
  • the module or ring may comprise a plurality of bores. This arrangement allows supply of ducting of diameters consistent with those used in industry.
  • a vertical connection arrangement for connection of two or more modules together in a vertical stack is provided, wherein the ring or module includes a snap fit or bump over connection arrangement which may comprise a protrusion at one side and a rebate at the opposite side, the rebate of a first module or ring being sized to cooperate to provide a snap fit or bump over with the protrusion of a second module or ring when the modules or rings are arranged in vertical alignment.
  • connection is a bump over, it is easily releasable whilst still providing a secure connection.
  • an integral lateral connection arrangement comprising a head and neck connector portion is provided in one module and a matched receiving portion to receive a head and neck connector of another module is provided.
  • the connection arrangement includes a stop. This arrangement allows modules to be connected in lateral alignment using the head and neck connection arrangement. By designing an integrated connection arrangement there is no possibility for connecting parts or fasteners to be lost. The provision of a stop ensures that adjacent sections are level when connected together.
  • the hollow part has an inner wall, an outer wall and a bore wall extending between said inner and outer walls and surrounding and defining a bore, it cannot be injection moulded with a simple mould without movable cores. In fact, it is difficult to mould and a complex mould it required, which includes at least one movable core. Indeed the mould may include two or even three movable cores.
  • the mould halves may be arranged to move relative to one another to release the moulded part by moving in any desired direction, but in a preferred embodiment the mould halves are arranged to move in a direction substantially parallel to the planes of the inner and outer walls.
  • the or one movable core forms the said bore.

  • step (b) repeating step (a) until the desired number of rings are formed
