BURIED CORRUGATED METAL STRUCTURES

A T L A N T I C

BURIED CORRUGATED METAL STRUCTURES INNOVATIVE SOLUTIONS, LOWER COST Buried Corrugated Metal Structures (BCMS) is the name given to Atlantic Civil Products range of corrugated metal pipe and plate structures. BCMS are used around the world for culverts, bridges, stormwater drainage, mine portals, reclaim tunnels, sheet water drainage, stormwater management systems and many other special adaptations.

C I V I L

Benefits of using BCMS: • LIGHTWEIGHT – Steel and aluminium structures facilitate easy handling with a mass approximately 1/10th and 1/30th respectively the mass of concrete structures. • STRENGTH – BCMS have great strength relative to their mass. The added stiffness provided by corrugations and positive soil arching around the circumference of structures enables comparatively lightweight structures to withstand high loads. For example those generated by high fills as well as the impact and vibration of heavy mining and construction equipment, trains, trucks and aircraft under shallow fills. • AESTHETIC APPEAL – BCMS provide an attractive landscape feature for entry statements. Square or bevelled end treatment options combined with local materials contribute to the aesthetic finish of the surrounding embankment and preservation of the local environment. • ECONOMICAL – Ease of transport and installation, low cost and pre-engineered design by Atlantic Civil Products make BCMS a more economical solution than concrete structures. • DURABILITY – BCMS have a proven performance record since the first Australian installation in 1913 and have recently celebrated their 100th anniversary of international use. Available in several material options, BCMS can be designed to meet your application needs.

• EASY INSTALLATION – Detailed design drawings of colour coded plate layouts facilitate fast assembly of MULTI-PLATE structures using lightweight equipment and nonskilled labour. Long length HEL-COR and HIFLO pipe barrels significantly reduce lay, align and join times compared to concrete structures. • EASY TO TRANSPORT – BCMS can be transported in greater quantities per truckload than concrete structures. The strong and robust nature of BCMS eliminates concern of structural damage commonly experienced with concrete structures when transported over long distances or arduous conditions. • SIZE – BCMS are available from 300 mm diameter pipes to structures spanning greater than 15m.

Atlantic Civil Products’ Buried Corrugated Metal Structures (BCMS) strength to weight ratio makes them extremely economical, particularly in large structures and/or under high road embankments. BCMS also readily support live load forces from highway and construction vehicles under minimal cover. Risks related to inclement weather or traffic conditions are minimised by the quick lay, align and join time for long length HEL-COR pipe barrels and the fast modular assembly of MULTIPLATE Structures. MULTI-PLATE structures can then be preassembled and lifted, towed or rolled into position. The use of natural materials for embankments around BCMS make them ideal where aesthetics or maintenance of the natural environment is important. In particular, arch structures have minimal impact to the natural topography of the stream bed. BCMS can be provided with the ends bevelled, skewed or a combination of both to conform to the embankment slope and alignment or with vertical ends to suit headwalls.

Expensive concrete headwalls are not required for most installations. BCMS facilitate staged road construction and readily accommodate future widening of the road formation.

The extent of variation in shape and availability of wide clear spans allows the designer to tailor the structure to suit the particular geometric requirements of the stream or underpass. Atlantic Civil Products SLOTTED DRAIN is a practical, aesthetically pleasing curb inlet for the drainage of hazardous sheet water off streets, highways, parking lots, malls, pedestrian thoroughfares and airport aprons. Atlantic Civil Products TROUGHING is effectively used as a batter or toe drain to collect and redirect surface water to minimise siltation and erosion.

A P P L I C A T I O N S

Atlantic Civil Products’ Buried Corrugated Metal Structures (BCMS) have long been used in the Railway Industry. In Australia since 1913, to date, there are in excess of 20,000 BCMS installed under Railway Live Loads. ‘Track Possession Time’ is the most important issue for railway operations and maintenance gangs. Long length HEL-COR pipe barrels provide a culvert solution that permits a battery of culverts to be installed while the line is kept operational. Unique, simple assembly techniques allow construction ‘under traffic’ by utilising preassembly, sub-assembly or plate by plate assembly of MULTIPLATE structures.

Entire structures can be easily rolled, dragged or lifted onto prepared foundations. BCMS are the ideal solution for line duplications and culvert replacement on elevated permanent way formations through flood prone country. Pre-fabricated bevelled ends conforming to the batter slope provide hydraulically efficient inlets which eliminate the delay and cost of constructing concrete headwalls. MULTI-PLATE rockshed (tunnel) structures withstand the massive impact loads of escarpment rockfalls allowing unrestricted travel through dangerous unstable cuttings. BCMS provide a smooth ride for passenger and freight traffic by minimising differential settlement of the formation adjacent to culverts and bridges, a common problem associated with rigid structures.

comparatively lightweight structures to withstand the crushing loads of large stock piles as well as the impact and vibration of heavy mining and construction vehicles under shallow fills. Being flexible, BCMS can tolerate considerable differential settlement, mining subsidence and seismic activity without structural distress. They provide the most economical solution in poor or moving foundation conditions. BCMS are ideal for remote site locations with difficult access. Freight costs are substantially reduced by the effective nesting of pipes and stacking of modular plates. The robust nature of HEL-COR pipe and MULTI-PLATE structural plate eliminates the risk of fracturing exhibited in pre-cast structures when freighted over long distances, or arduous conditions. For large projects, Atlantic Civil Products’ HEL-COR pipe mills can be mobilised for on-site manufacture. BCMS can be designed and pre-fabricated with a diverse range of features incorporating:

STORMWATER MANAGEMENT

B C M S

STORMWATER APPLICATIONS • URBAN DRAINAGE • STORMWATER TRUNK LINES The civil industry needs high performance stormwater systems using economical materials and construction technology. Atlantic Civil Products’ HIFLO pipe has been specifically designed to provide the flow characteristics of smooth wall pipe whilst maintaining the structural capacity and construction benefits of Atlantic Civil Products’ Buried Corrugated Metal Structures (BCMS). HIFLO pipe is tested and proven throughout the world to: • Save on total installed cost • Maximise discharge with smooth wall flow characteristics • Provide major reductions in construction time

A P P L I C A T I O N S

HIFLO pipe produces a smooth wall laminar flow with similar hydraulic efficiency to concrete pipe. Lay, align and join times for HIFLO pipe are often halved when compared to heavy concrete pipe. Large diameter HIFLO pipe barrels up to 12.0 metres long, are easily handled with lightweight equipment. Small diameter pipe can be quickly, easily and safely positioned by hand, particularly on sites which are steep, remote or poorly accessible.

A P P L I C A T I O N S

Government authorities are regulating developers to control runoff from new and higher density development. BUFFATANK stormwater management systems are the economical answer to downstream drainage overload and flooding problems. The low cost of an underground BUFFATANK system enables prioritisation of expenditure for above ground development. The system’s primary filtration prevents gross polutants from entering rivers, canals, harbours and foreshores. Removal of organic matter increases oxygen content of waterways and therefore helps sustain a healthier ecology. Retention systems are essentially identical to detention systems except the water is retained for some beneficial purpose. Other uses include irrigation, process water for industry and emergency containment of industrial spills.

HEL-COR PIPE

P R O D U C T

HEL-COR pipe incorporates the proven strength of sinusoidal corrugations. Pipe barrels are formed with a helical continuous lock seam running parallel to the corrugations. The result is an extremely strong yet light and economical pipe. MATERIALS HEL-COR pipe is manufactured from durable Z600 galvanized steel in accordance with AS1761 or a TRENCHCOAT polymer precoated galvanized steel in accordance with AS1761 and ASTM A742. Aluminium HEL-COR pipe is manufactured in accordance with ASTM B745 from Alclad 3004-H34 aluminium alloy. Steel HEL-COR pipe possesses exceptional load carrying capacity and is relatively light in comparison to reinforced concrete pipe. Aluminium HEL-COR pipe is approximately 1/30th the mass of concrete pipe.

MULTI-PLATE STRUCTURES

P R O D U C T

thrust beams assist in dispersing the loads from the crown to the surrounding backfill. MULTI-PLATE NOVA SPAN STRUCTURES MULTI-PLATE NOVA SPAN structures are available in spans up to 15m. The structures incorporate a MULTI-PLATE structure assembly with the inclusion of a composite concrete cap. The concrete cap spans the crown of the structure and surrounding backfill. This provides the inherent strength that enables low head room bridges, with road pavements placed immediately over the concrete cap.

D E T A I L S

MATERIAL MULTI-PLATE structures are manufactured in accordance with AS/NZS 2041 and are hot dipped galvanized to AS/NZS 4680 PLATE DESCRIPTION

MULTI-PLATE STRUCTURES MULTI-PLATE is the name given to Atlantic Civil Products’ range of bolted Buried Corrugated Metal Structures (BCMS). MULTI-PLATE structures are available in spans from 1.5 to 15 metres. Tables commencing on page 34 provide dimensions for standard structures. Geometric designs with alternative span and rise combinations can be custom designed to suit specific requirements. MULTI-PLATE SUPERSPAN STRUCTURES MULTI-PLATE SUPERSPAN structures span up to 12 metres using thrust beam longitudinal stiffeners. The concrete thrust beams are located at the junction of the crown and side plates. The

16

Plates are manufactured with sinusoidal 200mm pitch by 55mm depth corrugations running at right angles to the length of the plate. Specified plate thickness varies from 2.5mm to 8.0mm. Standard plates are supplied in factory curved 3000mm lengths, pre-punched along both edges and ends. Standard plates are manufactured in three net widths: 1175mm, 1410mm and 1645mm. Plates can be custom fabricated to suit almost any structure shape. NUTS AND BOLTS Galvanized 20mm diameter high strength nuts and bolts are used to assemble MULTI-PLATE sections. One side of the nut and the underside of the bolt head are uniformally rounded to fit tightly against the corrugated plate.

STRUCTURAL DESIGN

D E S I G N

DESIGN STANDARDS Atlantic Civil Products design Buried Corrugated Metal Structures (BCMS) in accordance with the following Australian and international standards: • MULTI-PLATE structures to AS/NZS 2041 • MULTI-PLATE SUPERSPAN structures to AS 3703.2 • HEL-COR galvanized steel pipe to AS 1762 and aluminium HEL-COR pipe to ASTM B790 • HIFLO pipe to ASTM A796 and B790 • Flanged Nestable pipe to AS/NZS 2041 DESIGN SERVICE Atlantic Civil Products’ Engineering Department offers an obligation-free professional design service for the application of BCMS. The service includes but is not limited to: structural design; hydraulic design; construction advice and details; durability advice; assembly drawings and installation guidelines.

Structures are custom designed to meet with the required clearance requirements or hydraulic waterway area. Detailed proposal drawings can be provided for: • Project viability • Tender documentations • Non conforming tender options HEIGHT OF COVER Minimum and maximum heights of cover are a function of the dead and live load, structure size geometry, and material thickness. Cover heights are determined in accordance with the relevant standards. Height of cover tables are available from Atlantic Civil Products for standard road and rail live loads. Atlantic Civil Products can determine the height of cover on structures from a range of popular construction and mining vehicles available on the company’s database. Special vehicles may be analysed from their design specifications.

MULTIPLE STRUCTURE SPACING Where two or more structures are laid parallel they should be separated by a distance sufficient to allow for placement and compaction of backfill. (See Table 11) ARCH OR FULL PERIPHERY? BCMS structures are available as arches or full periphery structures. Arches are generally more economical for sites with firm foundations. Full periphery structures provide significant savings for sites with low bearing capacity foundations. ARCH FOOTINGS Atlantic Civil Products provide footing reaction loads for footing design. BACKFILL MATERIAL SELECTION Uniform soil support is essential to the satisfactory performance of BCMS. Specifications provide for a wide variation of suitable materials. Bedding materials should be placed under full peripheral structures. This should be a 75mm thick uncompacted layer of coarse sand or gravel with 12mm maximum particle size. SELECT FILL for the backfill envelope should comply with the grading requirements given in Table

STRUCTURAL DESIGN

lineal shrinkage of 8 percent in accordance with AS1289.3.4.1. Select fill which does not fall within the grading limits of Table 12 is not precluded, providing it has a consistency and moisture content suitable for placement (without segregation) and compaction to achieve the specified density.

END TREATMENT

D E S I G N

Embankments adjacent to and around the ends of Buried Corrugated Metal Structures (BCMS) should be adequately protected from hydraulic forces. BCMS can be customed manufactured to suit the road or rail embankment slope. This results in substantial savings in the design and construction of inlet and outlet protection and allows for a variety of aesthetic end treatment options. (See Table 13). EMBANKMENT PROTECTION OPTIONS • Vertical concrete headwalls • Shotcreting • Revetment mattress • Stone pitching • Gabions • Stabilised fill sandbags • Concrete skirt on embankment • Natural vegetation HYDRAULIC APPLICATION If a structure is carrying water additional end treatment may be necessary for the following reasons: • To prevent scour or undermining • To improve hydraulic efficiency • To provide anchorage or support for the structure

24

TABLE 13: TYPICAL END GEOMETRY

SQUARE ENDS – Cut normal to pipe axis. BEVELLED ENDS – Cut to conform to embankment batter normal to pipe axis. SKEW BEVELLED ENDS – Cut to conform to embankment batter on structures skewed to the road or rail over the pipe. BOTTOM STEP – As for bevelled ends with a vertical bottom step. This is often used on larger diameter structures to stiffen the cut invert section. TOP AND BOTTOM STEP – A hood at the top of the structure provides additional protection and further stiffens the bevelled end.

CUSTOM FABRICATION

D E S I G N

The ingenious and effective use of BCMS in a diverse range of applications is testimony to the product’s versatility. Urban development, confined spaces and time pressures have led to the necessity for fast construction methods that minimise the need for curing of insitu concrete construction. The unique prefabricated design versatility offered by BCMS increases the scope of possible solutions and provides an edge for competitive civil construction. BCMS can be manufactured to incorporate the following special features: • Variation in vertical grade • Variation in horizontal alignment • Hydraulic drop structures • Pipe junctions, bends and bifacation • Bevelled and skewed ends • Access risers with optional internal ladders • Sediment pits • Pump pits • Trash racks/litter screens • Inlet/outlet connections • End walls/bulkheads • Open structure skylights • Stock pile feeder collars • Mine portal refuges • Hanging conveyor and service supports • Perforated drainage pipes • Ventilation pipes Atlantic Civil Products’ team of experienced engineers would be pleased to assist you in developing special conceptual and detailed design solutions.

DURABILITY

D E S I G N

SERVICE LIFE Based on long term detailed and critical investigations of an estimated 50,000 Buried Corrugated Metal Structure (BCMS) installations in a number of countries, service life assessment can be performed for a wide range of soil and water conditions. The service life of BCMS can be reasonably predicted based on: • The thickness and type of base material • Life of the coating • pH and resistivity of water and backfill material. The most practical method of predicting the service life of the invert for galvanized BCMS is with the American Iron and Steel Institute (AISI). (See Table 15). The chart limits the average metal loss to 25 percent. Because BCMS are designed with a structural

safety factor of at least 2.0 a significant safety factor remains at the end of the service life predicted by the chart. Thus use of the chart is considered reasonably conservative. When service life is controlled by invert performance, rehabilitation of the invert at the end of the predicted life can extend service life significantly. The tenacious protective surface oxide of aluminium makes it ideal for acidic environments and/or regions with relatively high soluble salt concentration. Aluminium metal loss rates for environmental conditions falling within the recommended range are negligible. (typically in the order of 5 to 7µm per year in drained soils).

Table 14 generally determines that soil side durability is not the limiting factor in designing BCMS. This is supported by a study performed by Corrpro Companies in 1986 where ‘Survey results indicate that 93.2 percent of plain galvanized installations have a soil side service life in excess of 75 years, while 81.5 percent have a soil side life in excess of 100 years’. WATER SIDE DURABILITY Abrasion is the result of mobilisation and natural movement of bedload material within a stream. The characteristics of bedload material, the frequency, velocity and volume mobilised, are factors that should be considered in the design phase. Abrasion velocities should be evaluated on the basis of frequency and

GENERAL

I N S T A L L A T I O N

INTRODUCTION As with all engineered structures, proper installation practices are integral to completing satisfactory installations. Reference should be made to the practices outlined in the appropriate Australian Standards for the following products: • HEL-COR pipe to AS1762 • HIFLO pipe to AS1762 • MULTI-PLATE structures, to AS/NZS 2041 • MULTI-PLATE SUPERSPAN structures to AS3703.2 • MULTI-PLATE NOVA SPAN structures, to AS2041 and Atlantic Civil Products installation guidelines • FLANGED NESTABLE pipe to AS2041 • BUFFATANK stormwater management systems to AS1762 The following pages are not

intended to be a complete set of installation instructions. The information included within this brochure should assist users in becoming familiar with the general procedures involved. INSTALLATION GUIDELINES Comprehensive installation instructions for Atlantic Civil Products’ range of products are available upon request. Installation instructions for MULTI-PLATE structures are provided with each order. CONSTRUCTION COVER LIMITS It is important to consider construction vehicle movements around BCMS because maximum strength does not develop until the backfill is compacted. Construction equipment is frequently heavier than the traffic loads for which the

structure has been designed. It is the responsibility of the contractor to ensure construction equipment does not cross the structure prematurely. Additional cover can be provided to support heavier construction vehicles. Minimum cover heights for specific construction vehicles can be provided by Atlantic Civil Products on request.

SITE HANDLING

I N S T A L L A T I O N

FIGURE 14: DE-NESTING HEL-COR AND HIFLO PIPE

HEL-COR and HIFLO pipe are not as susceptible as rigid pipes to onsite damage which may fracture or crack if not handled carefully. Long length and lightweight barrels translate to installation saving in time, labour and equipment costs. DE-NESTING PIPES HEL-COR pipes of smaller diameters can be ‘nested’ within larger diameter pipes to minimise freight costs. Small diameter pipes are easily removed by using a sling or chain. (See Figure 14). LAY, ALIGN AND JOIN Small diameter HEL-COR and HIFLO pipe may be hand lifted into position. Larger diameters can be handled by light lifting equipment. (See Mass tables on page 12, 13 and 15). Coupling bands have corrugations or dimples that lock into the corrugations of the pipe. Where pipe gaskets are supplied, these should be positioned and folded over one pipe end prior to aligning the next pipe barrel. After this next pipe has been laid and aligned, the flexible gasket is folded out and positioned evenly over the joint. Coupling bands should be positioned to overlap the abutted pipes equally. Tightening of bolts draws the

coupling band around the pipe to provide an integral and continuous structure. Large diameter pipes will be end match marked in the factory when this will further simplify installation. Installation times vary relative to site conditions,

proximity of materials, diameter and length of pipes being installed. Field observations have shown that the time to assemble coupling bands ranges from 5 to 25 minutes depending on pipe diameter.

These plates have embossed identification on their inside face and should be placed in the structure in the position shown on the assembly drawing. Full plates of the same radius and length are interchangeable.

MATERIAL SUPPLIED Plates are delivered to site in packs of approximately one tonne. PLATE IDENTIFICATION Standard plates are 3.1m long (3.0m effective length) and are supplied in three widths. (See Table 5, page 16). Plates of different radii are supplied with a flash of paint on one corner. Assembly drawings show the colour codes and the

BOLTING During assembly, connect the side and top plates with as few bolts as possible. Insert sufficient bolts to hold the plates in position, but do not overtighten the nuts. Loose bolting leaves the plates free to move slightly, which eases matching the remaining bolt holes. About three plate rings behind assembly, insert the remaining bolts. Start at the centre of the plates, and work towards the corners. When all bolts are inserted, tighten nuts. Nuts should be finally tightened to the torque shown in Table 17.

SPECIAL CONSTRUCTION TECHNIQUES Plate erection time can be reduced by practicing down hand bolting techniques and by pre-assembling multiple top or side plates on the ground, prior to lifting into position. Structures may be preassembled adjacent to the proposed site. This reduces the excavation’s exposure to flooding and minimises road and rail closure time. CREW SIZE Assembly crew size will vary depending on conditions and size of the structure. For an average structure, (say 80 100 plates) a six person crew would provide for efficient assembly. This allows for a crane or excavator operator, dogman, three labourers (assembling plates and bolt tightening) and one supervisor.

compacted material to provide adequate support. (See Figure 17).

EXCAVATION Where a structure is to be installed in a trench, the trench excavation width shall be determined after an assessment of the lateral bearing capacity of the adjacent insitu material. Where insitu material is proven to have equivalent or superior strength as the specified select backfill, its removal need only be sufficient for structure assembly and use of compaction equipment. Where insitu material is sufficiently strong and stable, flowable fill may allow further reduction in side fill width from 150 to 300mm depending on structure span. FOUNDATION PREPARATION The structure foundation shall be sufficiently strong, stable and uniform to support the full length of the installation, but shall not be stiffer than the undisturbed material supporting the fill on each side of the structure. Where the natural foundation is assessed as

32

suitable it shall be prepared to a level 75mm below the design structure invert level over a minimum width of half the structure span. (See Figure 17). Rock foundation shall be excavated to a depth 250mm or structure span/4, whichever is the lesser, and replaced with the compacted select material to a level 75mm below the design structure invert level. The minimum width of this zone of select material shall be equal to the structure span, and sufficient to ensure no part of the structure bares directly on rock so that unform support is provided. (See Figure 17). Soft or unstable foundation material (such as highly plastic clays or silts) shall be removed and replaced with suitable

BEDDING A uniform 75mm deep layer of uncompacted coarse granular bedding material shall be placed over the foundation and prepared to the correct line and level to allow the corrugations of the structure invert to bed in. Bedding material shall be coarse sand or gravel with 12mm maximum particle size and be placed to a minimum width of one third of the structure span. Bedding shall not be placed in the haunch zones of pipe arch structures. PLACING BACKFILL AROUND THE STRUCTURE The select fill material should be placed in horizontal, uniform layers of 200 to 300mm in thickness before compaction. Fill shall be placed in even layers on both sides of the structure with the difference between the select fill height on each side not exceeding 300mm. The select fill should be placed in accordance with the limits specified in Figures 15 and 16.

FOUNDATIONS, FOOTINGS AND BACKFILLING

COMPACTED BACKFILL DENSITY Unless otherwise specified by the designer, select backfill should be compacted to not less than 95 percent of the dry density ratio for standard compaction (cohesive soil) or 70 percent of the maximum density index for standard compaction (cohesionless soil). Reference should be made to AS1289. COMPACTION EQUIPMENT Compaction equipment may vary depending on the select backfill material.

Hand tampers are recommended for compacting underneath the haunches and adjacent to the structure. Most types of hand-held power tampers are satisfactory. Where space permits, sheepsfoot, rubber tyre and other types of tamping or vibrating rollers can be used to compact backfill. Details on the permitted proximity of the various types and size of tamping rollers can be supplied by Atlantic Civil Products. Light compaction equipment only should be used until the cover over the

FIGURE 15: BACKFILLING IN EMBANKMENT CONDITIONS

I N S T A L L A T I O N

structure is equal to the nominated minimum cover. STRUCTURE SHAPE CONTROL Regular monitoring of structure movement during backfilling is essential to maintain shape. Allowable construction and final structure shape deflection tolerances in accordance with the relevant Australian standards are available from Atlantic Civil Products.
