Description

UNDERGROUND CHAMBER ARRANGEMENT
FIELD OF INVENTION
The present invention relates to an underground chamber arrangement.
More particularly, the present invention relates to an underground chamber arrangement for telecommunication manholes.
BACKGROUND TO INVENTION
A manhole (alternatively utility hole, cable chamber, maintenance hole, inspection chamber, access chamber or sewer hole) is an opening to a confined space such as a shaft, utility vault, or large vessel. Manholes are often used as an access point for an underground public utility, allowing inspection, maintenance, and system upgrades. The majority of underground services have manholes, including water, sewers, telephone, electricity, storm drains, district heating, and gas. While it is less common to find telecommunications below ground in rural areas, though with the risk of theft and fire, these are also increasingly being run below ground, particularly telecommunications.
Manholes are generally found in urban areas, in streets and occasionally under sidewalks. In rural and undeveloped areas, services such as telephone and electricity are usually carried on utility poles or even pylons rather than underground.
The emergence of fibre telecommunications has created a demand for underground infrastructure which is easy to install and cost efficient to transport to remote areas. Original designs were based on civil structures which were cast concrete rings which were placed on top of each other until the required height was achieved. These are both difficult to transport as well as install. Previous developments included fibre cement pipes which were thinner walled and lighter. These were similarly cut into rings and installed as such. These improved transport weight as well as installation.
There have also been developments on modular manholes which are assembled from panels which greatly eases installation and transport costs. These are made from FRP (Fiber Reinforced Polymer) composites and may include resin, fillers and glass or other reinforcing fibers (e.g. Dough Moulding Compound, Sheet Moulding Compound, Polymer Concrete, GRP sandwich). There have also been efforts to develop fully plastic panels from Nylon and HDPE. Both of these modular options were designed with ribs and flanges for stiffness as these are lightweight and thin walled, but this solution struggled to support the required loads unsupported. In addition this is an expensive manufacturing process.
It is an object of the invention to suggest an underground chamber arrangement which will assist in overcoming the aforementioned problems.
SUMMARY OF INVENTION
According to the invention, an underground chamber arrangement includes at least two panels without stiffening ribs and being adapted to form a cylinder when joined together.
The arrangement may include a top slab or coping adapted to be located on top of the cylinder and to close off the cylinder.
The arrangement may include a base on which the cylinder is adapted to be supported.
The arrangement may include four panels. The arrangement may be lightweight.
The arrangement may be stiff.
The arrangement may be manufactured from Fiber Reinforced Concrete and/or Polymer Concrete and/or Fiber Cement.
The arrangement may exclude stiffening ribs in the panels.
The removal of stiffening ribs in the panels may optimize weight as well as packing density. The arrangement may have improved stacking density.
The improved stacking density may be of significant value as the telecommunications networks cover large and remote areas, so transport and access to equipment is difficult.
The arrangement may be manufactured from FRP Composite / HDPE / NYLON / and/or other plastic.
The panels may have a thickness from 3mm to 30mm.
The panels may have a length of up to 5m.
The panels may be joined by means of flanges.
Each panel may have a flange on both side edges.
The flanges may be connected by various means including bolts, rivets, clips, strips or knobs.
The panels may be stackable. The panels may include stiffening strips.
The stiffening strips may be limited to less than 30% of the overall height of the joining flanges.
BRIEF DESCRIPTION OF DRAWINGS
The invention will now be described by way of example with reference to the accompanying schematic drawings.
In the drawings there is shown in
Figure 1 : A side view of an underground chamber arrangement according to the invention and showing the lid, the four panels and the base;
Figure 2: A perspective view of the four panels of the underground chamber arrangement shown in Figure 1 ;
Figure 3: A second perspective view of the four panels of the underground chamber arrangement shown in Figure 2 but in exploded view;
Figure 4: A top view of the four panels of the underground chamber arrangement shown in Figure 2; and
Figure 5: A top view of the four panels of the underground chamber arrangement shown in Figure 4 but in exploded view. DETAILED DESCRIPTION OF DRAWINGS
Referring to the drawings, there is shown a underground chamber arrangement 10 in accordance with the invention.
The underground chamber arrangement 10 includes
(a) four panels 12, 14, 16, 18 without stiffening ribs and being adapted to form a cylinder 20 when joined together;
(b) a top slab or coping 22 adapted to be located on top of the cylinder 20 and to close off the cylinder 20; and
(c) a base 24 on which the cylinder 20 is adapted to be supported.
The arrangement 10 is lightweight.
The arrangement 10 is stiff.
The arrangement 10 can be manufactured from Fiber reinforced Concrete and/or Polymer Concrete and/or Fiber Cement.
The arrangement 10 excludes stiffening ribs in the panels 12, 14, 16, 18.
The removal of stiffening ribs in the panels 12, 14, 16, 18 optimize weight as well as packing density.
The arrangement 10 has improved stacking density.
The improved stacking density is of significant value as the telecommunications networks cover large and remote areas, so transport and access to equipment is difficult. The arrangement 10 can be made Sheet Moulding Compound or HDPE Plastic or Dough Moulding Compound.
The panels 12, 14, 16, 18 have a thickness from 3mm to 30mm.
The panels 12, 14, 16, 18 can have a length of up to 5m.
The panels 12, 14, 16, 18 are be joined by means of flanges 26.
Each panel 12, 14, 16, 18 has a flange on both side edges.
The flanges 26 can be connected by various means including bolts, rivets, clips, strips or knobs.
The panels 12, 14, 16, 18 are stackable to facilitate transport and reduce transport costs.
The arrangement may could include any number of panels. Even number of panels are preferred as this aligns entry and exit ports opposite each other for installation on a continuous line, but does not rule out odd number of panels.
The panels can include stiffening strips. The stiffening strips can be limited to less than 30% of the overall height of the joining flanges.
