Description

Apparatus for facilitating access to utility services for buildings The present invention relates to an apparatus for facilitating access to utility services for buildings, particularly, but not exclusively, to an apparatus for facilitating access to mains utility services, such as electricity, gas, water and communications for buildings.
In one embodiment this invention relates to the safe connection of statutory services on new build housing developments, which typically include electricity, gas, water and communications.
On new build housing developments, mains services are installed and made live in advance of dwelling construction. However, individual service connections cannot be made until the dwelling house is constructed and made secure.
Mains services are generally located in development footpaths. Presently, in the interests of site presentation and safe access to building plots, main service tracks are backfilled and the footpaths part constructed prior to dwelling construction. Consequently, it is necessary to excavate to expose the mains services in order to form the connections for each new house.
Excavation in the vicinity of live services is an extremely hazardous operation due to the possibility of damage to the mains from strikes by tools or plant. The consequences of such strikes are injury or death to operatives through electrocution or explosion.
This operation is made even more hazardous by the failure of utility contractors to lay mains services at the correct line and/or level. This means that the location of cables or pipes can deviate from their intended position thereby increasing the risk of strikes.
To compound matters, the connection of the individual dwelling services is S done by different bodies at different times. There can be a considerable lapse of time between these operations and in order to maintain safe site conditions, the excavations are generally backfilled to reduce the risk inherent in having open trenches into which vehicles or people can fall.
Therefore, the same pits can be excavated two or three times. This re-excavation greatly increases the risk of service strikes.
Service strikes present a huge problem to the house building industry.
Numerous initiatives based on procedure and working methods have been tried but most fail due to human error, high cost or adverse impact on other activities.
The present inventor has appreciated the shortcomings in these known methods.

Although not illustrated, it should be appreciated that the pairs of apertures 14 and the access apertures 16 may be formed by knocking out knock-out portions (examples of removable portions) of the side faces 12c, 12d, 12e, 12f of the casing 12.
In the embodiment illustrated and described here the casing 12 is a one-piece component that is manufactured from plastic, or glass reinforced plastic.
As described above and illustrated in figure ig, the apparatus 10 further comprises a lid member 12i. The lid member 12i is a square shaped member and is dimensioned to cover the open top face 12a of the casing 12. The lid member 12i is configured to engage with the lid support portion 12h of the upper portion of the casing 12, as described above.
The lid member 12i also includes apertures 12j that are used to lift the lid member 12i off of the casing 12. The apertures 12j provide an access point for a tool, finger(s), or hand of a user. The lid member 12i is made from a phenolic plywood with a non-slip finish on top.
As described further below, the casing 12 together with the lid member 1 2i is configured such that the casing 12 can support the weight of an average adult human standing on top of the member 12i, a footpath located on top of the lid member 12i, or light vehicular traffic on top of the lid member 12i.
With reference to figures 3 to 6, a description of the apparatus 10 in use will now be described.
Figure 3 shows the recommended arrangement of utility apparatus in a new footpath by means of cross section. Utility services to new developments (an example of a building) are located within either footpaths or shared service strips. This detail is adopted in Road and Footpath Construction detail drawings on new developments.
The Water, Gas and Electricity mains 20a, 20b, 20c are generally laid following the construction of the road 24, but before the permanent construction of the footpath 26.
Figure 4 illustrates the relationship between the footpath 26 construction, the service mains 20a, 20b, 20c and the apparatus 10 (preformed chamber, casing 12). 4°
The chamber (casing 12) may be manufactured in a variety of sizes to suit the arrangement of specific plots and distances between house service pipes or cables.
The apparatus 10 (preformed chamber) is placed on a prepared formation 28 (excavated land) 850mm below the level of the top of the kerb log 30 and set level from front to back and at a gradient corresponding with the footpath 26 side to side.
The casing 12 is installed in the prepared formation 28. The casing 12 may be installed in the prepared formation 28 and engaged with the mains utility service members 20 in two different ways.
In the first case the apparatus 10 is installed in the prepared formation 28 before the mains utility service members 20. In this arrangement the casing 12 is inserted into the prepared formation 28 and then the mains utility service members 20a to 20f are then passed through the pairs of apertures 14a to 14g of the casing 12.
In the second case the apparatus 10 is installed in the prepared formation 28 after the mains utility service members 20. In this arrangement the casing 12 is inserted into the prepared formation 28 on top of the pre-laid mains utility service members 20a, 20b, 20c. Since the first, second and third pairs of apertures 14a, 14b, 14c are open ended, as described above, the casing 12 can be positioned over the mains utility service members 20a, 20b, 20c, such that the mains utility service members 20a, 20b, 20c can pass through the pairs of apertures 1 4a to 1 4g of the casing 12. In this arrangement the knock out portions of the casing 12 may be knocked out before installation. The mains utility service members 20e and 20f can be passed through the pairs of apertures 14d, 14f, 14g.
Installing the casing 12 in the prepared formation 28 and then passing the mains utility service members 20 through the pairs of apertures 14a to 14g may be preferable in order to ensure the correct line and level of the mains utility service members 20. However, installing the casing 12 over pre-laid mains utility service members 20 provides the flexibility to allow use of the apparatus lOon a site where mains utility service members 20 have already been laid.
Once the apparatus 10 has been installed in the prepared formation 28 the dwelling utility service members 22a to 22g can be laid. The dwelling utility service members 22a to 22g provide water, gas, electricity, telecoms, cable, or satellite, television and low voltage electricity to the building adjacent, or associated with, the mains utility service members 20a to 20f.
Each dwelling utility service member 22a to 22g is passed from the building (not illustrated) through the access apertures 16a to 16e of the casing 12 and connected to the respective mains utility service members 20a to 20f. The dwelling utility service member 22a to 22g are connected to the mains utility service members 20a to 20f in the known manner.
Alternatively, the each dwelling utility service member 22a to 22g is connected to the mains utility service members 20a to 20f and passed through the access apertures 16a to 16e of the casing 12 to the building.
The service connections (dwelling utility service members 22) are therefore achieved by feeding the dwelling service pipes or cables into the chamber (casing 12) through the knock out panels (access apertures 16), which may be optional, on the walls perpendicular to the mains utility service members 20.
In the embodiment illustrated and described here the dwelling water utility service member 22a is passed through the first access aperture 16a and connected to the mains water utility service member 20a, the dwelling gas utility service member 22b is passed through the second access aperture 16b and connected to the mains gas utility service member 20b, the dwelling electricity utility service member 22c is passed through the third access aperture 16c and connected to the mains electricity utility service member 20c, the dwelling telecoms and cable, or satellite, television utility service members 22d, 22f are passed through the fourth access aperture 16d and connected to the mains telecoms and cable, or satellite, television utility service members 20d, 20e and the dwelling low voltage utility service member 22g is passed through the fifth access aperture 16e and connected to the mains low voltage utility service member 20f.
The apparatus 10 is designed to accommodate all of the commonly used cable and pipe scenarios in that: * The casing 12 is off sufficient depth to accommodate differing bed and surround depths according to the service diameters.
* Concentric knock out panels may be incorporated to allow different service diameters.
* Spare knock out portions (panels) may be included to allow for additional services -i.e. parallel mains.
Once the dwelling utility service members 22a to 22f have been connected to the mains utility service members 20a to 20f the lid member 12i is engaged with the casing 12, as described above. The lid may be preformed and placed in a recess (lid support portion 12h) on the top of the chamber (casing 12). The lid member 12i has hand hold cut outs to aid removal and replacement.
Once the apparatus 10 has been installed, a temporary footpath is installed over the apparatus 10. This involves backfilling the service track.
The sloping walls (side faces 12c to 12f) provide additional strength by spreading load over the surface area of the walls as well as the flange footing (flange portion 12h). The flange footing allows free draining of the chamber (casing 12) during the construction process. As described above, the bottom face 12b of the casing 12 may be open.
The lid member 12i and chamber (casing 12) are designed to withstand the load of a temporary footpath construction and foot traffic, thereby allowing safe access over service excavations.
The temporary footpath construction may be removed and access to the service mains (mains utility service members 20) gained via the removable lid member 12i.
Figures 2a to 2g illustrate an alternative embodiment of the apparatus of the present invention. The apparatus 100 of figures 2ato 2g is similar to the apparatus 10 of the first embodiment and the same reference numerals will be used to reference the same or similar features of the apparatus 100 of the second embodiment.
The main difference between the first embodiment and the second embodiment is that the casing 120 of the apparatus 100 is made from a number of components. That is, the casing 120 is not made from a single piece of plastic. Each component of the casing 120 is releasably engagable with the others.
Each side wall (side face) 12c to 12f is a flat panel that is releasably fastenable to another side wall by a plurality of releasable clips 13.
S The casing 120 also includes four support members 15. Each support member 15 is positioned between opposite facing side walls of the casing 120.
The support members 15 provide structural rigidity to the casing 120. The support members 15 positioned towards the upper portion of the casing also provide the lid support portion 12h in the same manner as described above in relation to the casing 12.
The operation and use of the apparatus 100 is the same as that of the apparatus 10 described above.
The apparatus 100 allows the casing 120 to be dismantled and flat packed for storage, transportation and the like.
The invention of the present invention avoids the hazards relating to the misalignment of the service members and multiple re-excavations of the prepared formation. The apparatus 10, 100 comprises a preformed plastic chamber (an example of a casing) which is designed to create an accessible void over the mains utility service members 20 by means of a removable lid (lid member 12i). Optional knockout panels in the walls of the casing 12, 120 provide routes for new service mains 20 at the correct line and level. That is the routes for the new service mains 20 are aligned correctly with respect to the prepared formation 28 and footpath.
The present invention therefore fulfils two main functions by: (i) Allowing access to underground mains services without the need for excavation, while maintaining safe site conditions; and (ii) Ensuring that the service mains are installed at the correct line and level.
The invention offers numerous advantages over the accepted industry methods, namely by: (i) Preventing the risk of injury or death to operatives engaged in the connection of new services by removing the requirement to excavate in the vicinity of live service mains; (ii) Preventing the risk of injury of death to operatives engaged in future maintenance, construction or repair in the vicinity of mains services by ensuring that they are laid to the correct line and level; (iii) Allowing individual service connections to be carried out at different times whilst maintaining safe site conditions; and (iv) Ensuring a cost effective method of achieving new service connections.
As noted above, the invention fulfils two main tasks. Firstly, it negates the need to excavate in the vicinity of live services in order to provide a service connection to a new property. This is achieved by forming an accessible void over the point of connection using a preformed plastic chamber (casing 12, 120).
The second function of the invention is to ensure that service mains are laid to the correct line and level.
It is the responsibility of those laying the mains to ensure that they are laid at the correct depth and in the correct position relative to the road kerb, however this can be difficult at the early stages of construction.
In practice, the existing ground levels on the footpath solum can vary greatly from the intended design levels. The utility contractor would not generally be contracted to reduce these levels and would therefore commence his excavations from the existing ground levels. This can lead to the main service being laid at the wrong level. This has the effect of leaving the cable higher than it should be and therefore vulnerable to an inadvertent strike.
The road kerb foundation should be used to determine line and level at this stage. However, due to site conditions and commercial pressures, those installing the services may not refer to this datum often, if at all. In addition, those responsible for checking the quality of work may find it difficult to determine if they have been installed correctly or not.
The invention provides a means of ensuring correct installation by utilising the road kerb as a datum. When installed level, the chamber (casing 12, 120) provides a predetermined route between plots for the service installer to work to, thereby preventing the deviation in line and level which leads to service strikes.
The invention includes one or more corresponding aspects, embodiments or features in isolation or in various combinations whether or not specifically stated (including claimed) in that combination or in isolation.
For example, features associated with particular recited embodiments relating to methods, may be equally appropriate as features of embodiments relating specifically to apparatus.
Modifications and improvements may be made to the above without departing from the scope of the present invention. For example, although the casing 12 has been illustrated as having sloping side walls (side faces s 12c, 12d, 12e, 12f), it should be appreciated that the side walls may be straight, i.e. the casing 12 may be cube-shaped with orthogonal side walls.
Similarly, although the casing 120 has been illustrated as having straight side walls (side faces 12c, 12d, 12e, 12f), it should be appreciated that the side walls may be sloping.
Also, although the apertures have been illustrated and described above as being circular or elongate, it should be appreciated that the apertures may be T-shaped.
