CONRETE POLES

Rocla is the pioneer in the manufacture of concrete poles in South Africa. The past ten years has seen particularly rapid growth in the use of concrete poles as timber and steel poles lost their cost effectiveness and became increasingly unacceptable environmentally. The Rocla product range falls into two broad categories: cast concrete poles which are cost effective for a wide range of applications and are made in lengths up to 13m; spun concrete poles which are manufactured in single lengths up to 24m and in jointed lengths to make a pole of 40m length.

Rocla spun and cast concrete poles have many advantages because they are:

• Maintenance free• Aesthetically pleasing and environmentally friendly• Resistant to vandalism and theft because they have: 1. No scrap or resale value 2. No value as wood or building struts for houses • Resistant to fire• Resistant to termites• Standard in dimensions• Made to client’s specifications with preformed holes• No drilling necessary. Assembly of fittings is easy• Amenable to being stored and stockpiled even in remote areas, because: 1. Weight of poles discourages theft 2. Poles will not corrode or rot 3. Rectangular profile is easy to stack

In addition Rocla spun poles are:

• Exceptionally smooth and durable. Routine maintenance inspections are not necessary. No protective coatings are required• Capable of an extra long service life from the high density spun concrete and the precision steel reinforcing cage• Non-absorbent. Traffic and any other markings can be painted on without the need for special primers• Constant in taper and dimension. Handling and installation equipment can be standardised

Rocla’s reinforced, hollow, spun concrete poles are the“benchmark” product for long life, zero maintenance,street lighting poles. The poles are available in a widerange of heights, load capabilities and fitting require-ments. The elegant appearance of the poles with its smooth light grey finish and continuous taper, makes it very attractive for street lighting.

Rocla’s spun poles for street lighting are manufacturedfrom high quality durable reinforced concrete in astandard range of lengths from 4,5m to 13.0m. The unique centrifugal process creates a uniformly dense strength concrete with smooth, impervious, finish. The standard lighting pole is made to the strength specifica-tion in SABS 470. Other strengths and lengths can be designed and manufactured to suit customer require-ments. All Rocla street lighting poles conform to SABS 470 and carry the SABS Mark of Approval.

Earthing

Rocla’s poles are manufactured with an integral earthingsystem. Stainless ferrules, flush with the outside of thepole, provides an electrical connection to all of the pole’sreinforcement wire.

Abnormal Environments

Rocla design engineers are available to advise on the most cost effective way of customising the lighting poles to suit a marine environment or particularly aggressive soil conditions. Design modifications for these circum-stances may be additional cover for the reinforcing or protective coatings; an appropriate concrete mix would be designed incorporating pulverised fly ash, slagment or condensed silica fume.

POLES FOR ELECTRICITY

A vision of electricity for all the people of South Africa was well established in Eskom more than three decades ago. Rocla fully subscribed to and supported it. Together we researched and developed concrete poles for use in electrical power transmission and distribution.

The pilot concrete pole project was Orange Farm, acooperative effort between Eskom, Rocla and othercompanies. Rocla now provides economical cast con-crete pole systems to the electrical distribution market.

The technically advanced tall spun pole has been used on transmission lines for new development areas such as Richards Bay, Venetia Mine etc.

As detailed on page 3 under “Poles for lighting”, pro-vision for earthing is integral to a Rocla pole and the design can be readily customised to suit aggressive environments. Rocla has the technical and manufacturing skills to provide concrete poles for the country’s electrical distribution needs far into the future.

CAST POLES FOR ELECTRIFICATION

The electrification of South Africa’s townships needs to be done on a cost effective, productive basis. The Rocla cast concrete pole has become a standard for this purpose with many advantages over traditional wooden poles and is used extensively by Eskom and other developers.

Advantages

• An optimised design enabling the use of standardised fittings and aids productivity of installation.• The concrete pole is resistant to vandalism and fire.• Maintenance-free and long life design Rocla concrete poles tackle the challenge of township electrification with a system that has the versatility of above ground installation while being a cost effective long term product.

RETICULATION POLES

Reticulation systems for electricity typically refer to the supply of 11kV and 22kV power to farming communi-ties and other outlying facilities. One of the particular advantages of the concrete pole for this purpose is its resistance to veld fires. The cost of replacing damaged wooden poles far outways the cost of a concrete pole. These days it is, in any event, normally more cost effec-tive to install an original concrete system, than a wooden one based on life-cycle costing.

Rocla’s concrete poles can be designed with precast holes and the strength to accommodate the customer’s conductor span lengths. The standard design suits stand off insulators. With this, the assembled pole is fully maintenance-free and presents a very neat, pleasing appearance.

NOTE: Although the above are standard lengths and strengthsmanufactured by Rocla intermediate length strength can be designed too.

NOTE: Please see D-DT-253 series for more information on SpunConcrete pole designs for 132kV transmission lines.

Rocla’s technically advanced spun concrete poles are well suited for the exacting requirements of electrical distribution line construction. The durable, maintenance- free poles are not only very strong but are uniformly strong through 360° unlike the normal cast concrete poles which have a major and minor load axis. The spun pole derives its extra strength properties from the unique centrifugal manufacturing process which gives uniform densely compacted concrete along the whole length of the pole. The last stage of the spinning cycle also removes water that is surplus to cement hydration requirements.

Spun poles are invariably less expensive on an installed basis than alternative systems and because of their long maintenance-free life are certainly more cost effec-tive longer term. Part of the cost saving arises from the smaller servitudes, less expensive footings and quicker installation for concrete poles compared with alternative systems. Rocla manufactures its standard range of poles in accordance with Eskom’s specifications. However Rocla’s engineering resources are able to cater for a client’s special needs.

This design drastically reduces the incentive for theft and vandalism. The advantage of small servitude needs is also well appreciated by farmers: particularly those doing intensive farming on high value land.

Distribution structures such as transformer poles, air break switch supports and underground cable termi-nations can all be replaced cost effectively with Rocla concrete pole systems. The standard systems are Eskom approved and poles are type tested at Eskom’s Rosherville Testing Station.

Security and Monitoring

In the world of today, Rocla’s concrete poles are playing an important role in the particularly strong market growth sectors of security surveillance and intelligent transportation systems (ITS).

Rocla Spun poles are ideally suited to provide perma-nent, low maintenance, vandal proof structures to affix CCTV cameras or monitoring equipment. Rocla poles do not require any stays to prevent movement unlike steel poles.

The pole design allows for the cables to be fed from the ground through the pole, which is hollow, so that tamper-ing or theft of cables is significantly reduced.

We have supplied numerous poles along major routes in Gauteng as well as large security companies who have chosen Rocla poles for the right reasons.

Stadium Lighting

Particularly international sport is increasingly a significant revenue earner for our country, important for our image abroad and is playing a major role in building a sense of pride and belonging among all our people. Whether at the international facility level or at local recreational level, sports grounds need to be suitable for years of maxi-mum utilisation. Rocla’s spun concrete poles provide a versatile, aesthetically pleasing, maintenance-free and vandalism-free, solution for floodlighting poles that are an investment in the decades ahead.

Park and Public Lighting

For people to enjoy the benefits of parks and public areas to the full, the security aspects have to be addressed and be environmentally compatible. Area lighting has an important role to play. Rocla concrete poles will generally be less expensive to install than their steel and fibre glass equivalents, while giving additional benefits of durability, zero maintenance and attractive appearance.

The recent rapid coverage of the country’s main urban areas and connecting roads with tall microwave cellular telephone masts had been handled with appropriate con-cern for the environment. Rocla was able to satisfy the need for an environmentally friendly structure with their elegant spun concrete pole. Rocla’s product is also more cost effective than traditional alternatives, while offering a maintenance-free, longer lifespan.

The standard design Rocla concrete pole, catering for a pre-determined load and standardised fittings, is extremely cost effective. Whatever telecom cables are involved, whether lightweight or heavy multicore copper, Rocla’s engineering department can create appropriately optimised designs to suit the need.

Testing

Rocla’s manufacturing facilities are all ISO 9001:2008quality management systems accredited. It is Rocla’spolicy to test poles to SABS 470 specifications and stamp it with a unique traceability reference.

The scope of the testing procedure covers:

• Inspection• Test Frequency• Dimension checks• Straightness tests• Proof Load test• Cover to reinforcing checks• Torsional test• Ultimate load test

Rocla’s testing policy exceeds the requirements for testing frequency laid down in SABS 470.

Manufacturing Process

Rocla’s spun poles are manufactured from high qual-ity, durable, partially prestressed or reinforced concrete. Precision formed reinforcement cages are made from circumferential spirals, resistance welded onto longitu-dinal wires. To ensure correct concrete cover, the cages are positioned in steel moulds using stainless steel spacer studs, concrete is then introduced and the mould is spun. The poles are steam cured before being stripped from the mould. This centrifugal process creates a uni-formly dense high strength concrete with a particularly smooth finish.

Rocla’s cast poles are made in steel moulds from high quality concrete with a mix designed to achieve the strength and durability required by the customer. The mix is vibrated and steam cured before removal from the mould.

MANUFACTURING AND TESTING

www.rocla.co.za

13

Transporting

Normal cast concrete poles should be transported withthe narrow face of the pole upwards. Layers of poles must be separated by timber bearers not less than 100mm x 100mm in section. The bearers should be placed ¼ of the pole length from each end of the con-crete pole together with a centre support. To prevent lateral movement and damage to the poles during transportation, they should be placed with the butts in each layer together with packaging material between and securely strapped. To even out the load distribution it is good practice to alternate the pole tips and butts between layers.

If poles of different lengths are being transported, thelonger poles should be placed in the bottom layers.

TRANSPORTING, HANDLING AND STACKING

Where it is not possible to have wooden bearers for the shorter poles positioned vertically above the lower bearers, rubber tyres should be used under the bearers to provide resilient support.

The transportation of spun concrete poles up to 12m inlength requires a trailer with a rigid loading platform andchassis. The sides of the trailer should be fitted with steelhooks spaced at not more than 1m apart to attach holding down straps or chains.

Poles exceeding 4.5m in length must be supported at aminimum of three points. To secure the load to the trailerwithout damaging the surface of the pole, chains coveredwith protective rubber, strapping or rope should be used.

www.rocla.co.za

14

Handling

Care must be taken when handling, transporting andstoring concrete poles to avoid overstressing them orcausing surface damage. Lack of care can be costly.Damage can be caused by dropping poles, knocking them together or subjecting them to point loads.

When unloading poles by crane on site, a single point liftmay be used. Please contact your nearest Rocla officeto establish the correct position of the lift points for theparticular poles. To avoid point loads or abrasion damageat the lift point, a protective timber “corset” about 0.5mlong should be used. If no suitable timber is available, use a thick wrapping or canvas or jute bagging under the lifting chain. Alternatively use a fabric sling.

When the pole is to be lifted for insertion into the ground,a one point lift must be used. The lift point must be ¹/³of the pole length from the top of the pole. Guard againstlocalised damage at the lift point by taking the precau-tions given above.

For two point lift, the lifting positions should be ¼ of thepole length from each of the pole.

Stacking

Poles should be stored on a hard, level piece of ground.The poles should be placed ¼ of the pole length from each end of the concrete pole together with centre support.

When stacking several layers high, position timber bear-ers between each layer vertically above the bearers below. For stable, safer stacking of tapered poles, alternate the tips and butts of each layer. Do not stack more than eight layers high.

It is good, safe practice to have separate stacks for eachlength, diameter and type of pole.

INSTALLATION

Planting Poles

All Rocla poles carry a mark which indicates 1,5m abovethe design ground level in order to gauge the correctplanting depth.

Pole holes should be dug so that the access slope into the hole be parallel to the feeder line. The width of the hole should be as narrow as possible, while allowing the pole to be planted to the correct depth.

A practical way of planting large poles is as follows:

Use a concrete manhole as a sleeve. This sleeve could be planted and backfilled as described below. This method limits the craneage cost on site. The poles could be chocked into position and the annulus between sleeve and pole could be filled with a sand/cement mix afterwards.

www.rocla.co.za

16

INSTALLATION

Compacting Soil After Planting Poles

After a pole has been planted to the required depth,dampen the soil that is to be used to fill in the hole. If thesoil is squeezed in the hand and holds its shape when the hand is open, it indicates the right moisture content to ensure good soil compaction.

It is important to note that there is no point backfilling thehole completely and then trying to compact the soil. Theeffects of compaction only penetrate about 300mm of soil. Therefore backfill the hole 300mm layers at a time.Compact each layer with a mechanical compacter orwith a hand stomper of a least 25kg in weight. Drop thecompactor 400mm per blow and apply 30 blows to eachlayer of soil around the pole.

If you encounter difficult soils the procedure must be modified:

• A loose soil that does not compact when wet must be thoroughly mixed with three pockets of cement for each m3 of material. The above compaction procedure can then be carried out 300mm layers at a time. Note that the pole will need at least two days before any tension can be applied.

• A very clayey, wet soil must be replaced altogether by an imported soil. The imported material should preferably be a well grade silty soil. This should be mixed with cement, as previous described, moistened and used as backfill according to the previous compaction procedure.

In the case of tall poles, such as low voltage 7m concretepoles, in a wet clayey area, extra stabilising will be needed. It is recommended that four concrete lintels (1.0m long x 100mm x100mm) are used as baulks. Two concrete lintels must be placed, one on top of the other, at the bottom of the hole. They must be placed against the pole on the opposite side to the intended service take off. The soil behind the lintels must be very well compacted as described above for clayey soils. At 400mm from the surface, the other two lintels must be positioned, one on top of the other against the pole, on the same side as the intended service connections. Finally the soil behind these two lintels must be thoroughly compacted. If the hole is water logged, the water must be removed before backfilling with a cement stabilised appropriate soil.
