PRODUCT OVERVIEW

Box Culverts

Easy to install, suitable for very shallow or deep fill, idealfor use in a wide variety of civil engineering applications

4

Hanson Building Products is the

largest producer of box culverts in

the UK, and are members of the

Box Culvert Association.

Since its introduction over 45 years

ago the range of box culverts we offer

has continued to expand.

Whilst offering increased flexibility

Hanson Box Culverts retain all their

original advantages.

They are easy to install and can bemade to suit very shallow or deep fill.

They also offer economy by being

uniquely designed for particular loading

conditions and are efficiently produced

in standard sizes.

As these advantages have become

widely recognised their range ofapplications has increased making them

ideal in a wide variety of civil

engineering applications.


5/24

Hanson Box Culverts are available in

a range of 144 standard sizes from

1000mm x 600mm to 6000mm to

3600mm. Non-standard sizes and

internal profiles can also be readily

provided including shaped inverts,

dwf channels, and units with cross

over channels.

Reference to our table of standard

sizes will give the size necessary to

meet any conditions which may be

required in terms of storage volume,flow capacity etc. For larger culvert

widths, twin or multiple sections may

also be considered.

Unlike pipes and corrugated steel

assemblies, box culverts can be

designed to carry vertical load without

the relieving effect of side pressure.

Therefore, when culverts are used in

multiple sections, they can be laid side

by side with only a nominal gap

between them.

By comparison with arched or circular

sections no flow area is lost through

either excessive spacing apart orcurved profiles.

DESIGN & SPECIFICATION

Box Culverts

Hydraulicdesign

Discharge rates for box culverts in the

Hanson standard range are calculated

for a gradient of 1 in 1000 in

accordance with the Colebrook-White

equation assuming the culvert running

full under uniform flow conditions.

Comparable discharge rates for

circular pipes are given in the Table 2

(overleaf).

For any gradient between 1 in 1000

and 1 in 250, the gradient multiplier

(Table 3 overleaf) should be applied.

A value of 0.3mm has been assumed

for roughness coefficient, ks, which

depends upon the accuracy of laying

and jointing in addition to the quality

of the culvert surface. Where a

different value is required, the

discharge rate at the appropriate

gradient should be adjusted by the

use of the roughness multiplier

(Table 4 overleaf).

Thus, for a 2400 x 1200 section laid

at a gradient of 1 in 500 and with an

assumed roughness coefficient of

0.6mm, the discharge rate is given by

4.29 x 1.4 x 0.93 = 5.59m3/s.

The flow capacity of a culvert is

determined by a number of different

factors. In addition to the gradient and

roughness coefficient, the geometry

of the inlet and outlet and the

tailwater level can affect the mode of

flow and may prevent the culvert from

running full or under uniform flow

conditions.

In such cases the flow capacity will be

lower than the full discharge rate.

Surface loadingand fill depth

Loading applied at the ground surface

and weight of fill material produce a

combination of vertical and horizontal

forces on the box culvert.

Surface loading may be specified as a

standard loading type, equivalent

uniform loading or individual wheel

loads. The critical load on a culvert can

occur at minimum or maximum fill.

Each enquiry for a culvert should state

the minimum and maximum fill depth

and the amount or type of surface

loading.

It is recommended that the minimum

fill depth should be not less than

200mm or one fifteenth of the internal

width of the culvert if this is greater.

Design anddetailing

Box culverts are generally designed

and detailed in accordance with the

Box Culvert Association Standard

Specification which covers materials,

manufacturing tolerances, external

loading design and detailing standards.

Box culverts carrying highway loading

or railway loading are designed to

current standards and specification as

stipulated by the client.

The lowest grade of concrete used is

C45/55 with a 20mm maximum size

of aggregate. The nominal cover to

reinforcement complying with the

exposure requirements of BS8500.

An experienced team of engineers and

technicians backed by CAD facilities

provide a flexible and comprehensive

design and detailing service enabling

the clients design and specification

criteria to be satisfied.

INSTALLATION GUIDE

Box Culverts

10

Delivery and offloadingIt is the contractors responsibility to

offload the box culverts on delivery.A hard level access area should be

provided which can be used safely by

standard articulated delivery vehicles.

The contractor should provide a

suitable crane of adequate capacity

for lifting the culvert.

For reasons of safety and economy

certain box culverts are delivered tosite on end rather than as laid, and will

require a safe method of turning during

offloading. A data sheet giving

guidance of lifting and turning is

available and is issued to clients prior

to the first delivery.

The offloaded box culverts should be

levelled carefully on a firm level baseaway from the edge of the trench, and

if any further movement is required it

should be by lifting; the culvert should

never be dragged or dropped.

Bedding, laying and backfillingExcavation can be kept to a minimum

with only nominal working space

required on each side of the box

culvert. When working in trenches the

normal requirements for health and

safety must always be observed.

The base of the trench should be

uniformly prepared before laying a

200mm bedding of compacted granular

material over the full width of the

trench. A surface blinding of the fine

material will assist levelling. Localpackings are subject to settlement and

should not be used.

As an alternative to granular bedding a

concrete blinding layer is sometimes

preferred to protect the formation or to

allow a faster rate of laying the culverts.

A layer of unreinforced concrete

approximately 75mm thick on a trench

bottom which has been well prepared

to provide a uniform support is

generally sufficient.

A culvert line is usually laid directly on

the bedding starting from the

downstream end with the sockets facing

upstream, to receive the next culvert.

The trench should be backfilled as soon

as possible after the culvert has been

laid and it should be filled evenly on

each side of the trench. Backfilling

should continue in 200mm compacted

layers to reach the required depth of

cover.

Where loads from construction plant

may exceed the design load of the

box culvert protective measures will

be required. This is particularly

relevant at shallow fill depths.


11/2411

JointingThe culvert sections generally have

rebated joints and can be laid open, orsealed using pre formed strips and/or

pointing materials. Reference should be

made to the jointing material

manufacturers specification and

recommendation for use of the product.

A system using preformed strip within

the joint is most commonly used. When

the strip is bitumen based the joint

faces should be cleaned, primed and

allowed to dry.

The strip is then applied to the internal

corner of the socket just before the

culvert is laid in the trench.

Joints are closed to a nominal gap by

pulling against previously laid culverts

with an applied load of approximately

one tonne per metre of strip plus about

half of the weight of the culvert unit to

overcome base friction, less if the unit

is suspended from the crane whilst

jointing.

Heat may be required to soften the

strip when working at low temperature.

When the box culvert is of sufficient

size for access, it can be pointed

internally with an elastomeric or

bitumen based material using a suitable

primer. Not all methods of jointing,

however, should be expected to be

completely watertight.

PRODUCT OVERVIEW

Omnia Bridge Deck

Provides a solid base for deck slabs on Civil Engineering structures

12

Omnia Bridge Deck

Hanson Building Products has supplied

Omnia Bridge Deck for numerous

projects to most civil engineering

contractors.

Omnia Bridge Decking is a practical

and economical means of providing

permanent formwork to deck slabs of

bridges, especially where these span

over live roads, rail tracks and rivers.

Omnia Bridge Decking can be

considered as participating formwork,

and the concrete and reinforcement in

the pre-cast plank taken as part of the

deck with corresponding cost savings

compared to traditional methods of

construction.

Design details and cross sectionPRODUCT DETAILS

Bridge Deck

The planks are primarily designed to

cope with temporary condition loads

only, however it is very often the case

that Bridge Designers use the

reinforcement provided as part of the

permanent works design, and

furthermore often ask us to increase

the amount of reinforcement in the

plank thereby saving reinforcement inthe in-situ portion.

Hanson Building Products design the

planks to carry construction loading

but also limit deflections to span/400

and crack widths to 0.1mm in the

temporary case.

Wherever possible. the correct size

of lattice girder will be selected to

provide a chair for the top mat of

reinforcement and they are aligned

during manufacture to ensure ease of

fixing longitudinal reinforcement over

the Omnia planks.

There will normally be 3 or 4reinforcing bars cast within each plank,

minimum 10mm diameter, maximum

16mm diameter.

The Interim Advice Note

(IAN 74/06) allows 35mm cover to

the reinforcement at the soffit.

Threaded anchors can also be cast

into the planks for supporting lighting,

drainage etc.

A typical cross section of a Bridge Deck plank shows the arrangement of the lattice girder and the reinforcement within the precast concrete.

ManufactureOmnia Bridge Deck is manufactured

to all relevant British Standards andthe Specification for Highway Works,

using C40/50 concrete in planks

300mm wide x 60mm deep, although

special widths can be manufactured up

to 600mm wide for use as infill panels

at transverse beams or abutments.

Each 300mm wide Omnia Bridge

Deck plank has an Omnia lattice girder

centrally placed and the plank is

reinforced with either 3 or 4 steel bars

10-16mm dia.

The upper surface of the Omnia planks

has a Class 2 finish as required by the

Specification for Highway Works

to expose the aggregate.

This surface accommodates the

horizontal shear stresses at the

precast/in-situ interface. The

manufacturing tolerances and soffit

finish (Type F2), are also as specified

and the production process is

controlled by the procedures set out in

our model specification.

The Omnia lattice girder is at the heart

of all of the Omnia product range and

is responsible for ensuring that the

panels will span the required distance

in the temporary condition. The latticealso acts as a physical link between

the precast panel and the in-situ

portion, and as lifting points during

erection. We will also endeavour

wherever possible to provide a lattice

girder that is set at the correct heightfor placing of the top mat of

reinforcement.

DimensionsOmnia Bridge Decking can be

manufactured in lengths up to 3.80m

and depending on the overall slab

depth can be used for clear spans of

3.69m with a preferred bearing of

55mm at each end.

The graph below shows the maximum

clear span for a range of span depths.

Please contact the office for spans and

depths outside of this range.

The long edges are formed with a

chamfer to the underside, so that when

placed adjacent to each other, the

effect of a birds-mouth joint at 300mmcentres can be seen on the soffit.

Planks can be manufactured with

skewed ends to suit the shape of the

structure if necessary, however as the

maximum plank length can be no

greater than 3.80m, the clear span will

be reduced.

DELIVERY, OFFLOADINGAND ERECTION

Bridge Deck

Omnia Bridge Deck Planks are

generally laid on Structural Steel

beams, and whilst the details and

recommendations below may

apply to other structures, they are

primarily written for Steelwork

structures.

PreparationBearings

All bearings should be structurally

acceptable before any Omnia planks

are placed. Any variation in levels of

bearing will need to be addressed prior

to the planks being delivered.

Temporary Supports

Omnia Bridge Deck planks are always

designed to be erected without any

temporary props during the

construction sequence.

Minimum Bearing Dimension

All planks will be designed to have a

minimum bearing of 55mm both ends,

therefore the minimum plank length

will be clear span + 110mm to a

maximum of 3.80m.

Prevention of grout loss

We would recommend that flanges

of steel that will be supporting Omnia

Bridge Deck planks be treated to

prevent grout loss when pouring the

in-situ section of the slab. We would

suggest a 12mm deep bituminised

compressible strip available from

a number of sources including

Illbruk Alfas at Washington

(0191-419-0505).

SafetyNotesNotwithstanding the above, propping

may be necessary in the following

circumstances:-

Where the top or diagonal bars

of the Omnia lattice has been

cut or damaged.

Where the bearings are not true

and or level.

Where a bearing of less than

40mm is provided

Cantilever sections and

adjacent to the edges of

large openings

DeliveryOmnia Bridge Deck planks are

generally delivered on articulatedvehicles paletted in batches of 24

planks (6 deep x 4 wide) and will be

delivered to a previously agreed

sequence of planks and times/dates.

Depending on the spans of the planks,

each delivery will have approx. 130m

of planks. Except where agreed

previously, the first delivery of planks

will come with a lifting frame which

should be used to lift a layer of planks.

Offloading

We would recommend that full pallets

of planks are offloaded adjacent to

their ultimate position on the

structure, and then each layer is lifted

and placed in position at a later date.

All personnel who are required

to be on the trailer bed whilst on

site should be protected from

falling from height in accordance

with The Work At Height

Regulations.

A lifting frame will normally be

provided to suit 4 planks and will

weigh approx 500kg, however ifrequired, a larger frame can be

provided (weighing approx. 750kg) to

lift 8 planks, in which case pallets need

to be placed adjacent to each other.

Lifting Weights

ErectionHandling

Units must be lifted and placed

without jerking to prevent cracking to

the panel or damage to the lattice.

Always lift Omnia panels by the lattice

with the hooks positioned under the

diagonal.

Protection against falls

In line with the PFF Code of Practice,

the erection of Omnia units will be

subject to the application of a hierarchy

of safety systems as recommended by

the HSE. There are a range ofmeasures available from passive systems

such as working platforms, staging,

safety nets and air bags to active

systems such as work restraint/fall

arrest using safety harnesses.

Slab CompletionPlacing in position

Panels lifted in sets of 4 will be approx1200mm wide (8 planks will be 2.40m

wide) and will need to be butted

together to close any gap between

them, minimising the risk of grout loss.

It is recommended that a method of

setting adjacent sets be adopted so

that each set is placed at 1200mm

dimensions. This will keep the layout of

the planks close to that on the

drawing, the amount of gaps to a

minimum, and reduce the risk of any

cutting or make-ups due to creep.

Joint Grouting

Joints will need to be addressed to

prevent grout loss during concreting.Various methods can be used, and we

would suggest a bead of sand/cement

grout towelled along all joints.

Placing of Reinforcement

Reinforcement will need to be placed

in accordance with the Structural

Engineers requirements and one layer

may need to be threaded through the

diagonals. Other layers are placed

between and over the lattice.

Concreting

The slab will then be concreted in

accordance with the Structural

Engineers specification.

Each plank weighs 36kg/m and each pallet will normally have 24 planks.The pallet weight will need to calculated prior to uplifting from the vehicle,

and the layer weight of 4 (or 8) planks will need to be calculated before

lifting to the structure.

PREFABRICATED WALLPANEL SYSTEMS

Hanson have developed a suite of

prefabricated panels which include

precast concrete, masonry or

composite panels of brick/block and

concrete with or without insulation.

These may be used for retaining walls,

parapets, bridge abutments, flood

defence systems or as both external

and internal walls for buildings

Where speed of construction and a

high quality finish are necessary,

Hanson's QuickBuildTM and FloodWallTM

products provide rapid installation of

finished masonry components.

Wall panels may consist of single leaf

masonry of clay brickwork, concrete

blockwork or natural stone, or a

composite precast concrete/masonry

construction. Wall lengths can vary

up to 9m.
