32 BRIDGE SIZE REINFORCED CONCRETE BOX CULVERTS

32.1 GENERAL

In accordance with Section 2 of this Manual, a culvert is defined as a covered channel consisting of one or more adjacent enclosed cells of rectangular or other shape,

for conveying a watercourse or stream below formation level.

Culverts may also be used to provide property access, an underpass for the safe movement of livestock or an underpass for the safe passage of fauna from one side of the road corridor to the other side of the road corridor. Reinforced concrete box culverts may be cast-in-place or may be constructed from precast crown units on a cast-in-place reinforced concrete base slab. The width of the culvert shall be given as the distance between outer faces of outer crown units along the centreline of the road. The width of the culvert is the governing factor in determining if the culvert is to be classified as a bridge and therefore assigned a Bridge Number in RTA’s Bridge Inventory System (BIS). Where the width of the culvert is 6 metres or more along the centreline of the road, for the purposes of inventory, it shall be deemed to be a bridge and it shall be assigned a Bridge Number by the Regional Bridge Maintenance Planner in the Regional Office of record. Plans for the culvert shall carry a “BC” type Plan Registration Number sourced through the RTA’s Micrographics Unit. In accordance with RTA business rules, in all cases where culverts are used as an underpass for property access, the movement of livestock or the safe passage of fauna from one side of the road corridor to the other side of the road corridor, irrespective of length along the road centreline, they shall be deemed to be a bridge. Such culverts shall be allocated a Bridge Number by the Regional Bridge Maintenance Planner in the Regional Office of record and plans shall carry a “BC’ type plan registration number. Cast-in-place reinforced concrete box culverts shall be fully detailed on the design drawings. Precast reinforced concrete crown units and link slabs shall be designed and supplied in accordance with RTA QA Specification R16 – Precast Reinforced Concrete Box Culverts.

32.2 COVER SHEETS The Cover Sheet shall be prepared in accordance with Section 20 of this Manual. Where the culvert is constructed using precast reinforced concrete crown units and link slabs, the Cover Sheet shall carry the following note: “Crown units and link slabs shall be supplied in accordance with AS 1597.2” with any special design traffic loading or loadings being added to the note. In all applicable cases, a Construction Loading diagram, together with any necessary information and/or supplementary notation, shall be provided on the Cover Sheet. Where the culvert is located at a defined watercourse, the title used on the Cover Sheet and detail sheets shall be in the format shown in Figure 32.2.1. The name of the watercourse shall be provided, along with a reference distance and direction from a known location.



Where the culvert is located where there is no defined watercourse, the title used on the Cover Sheet and details sheets shall be in the format shown on Figure 32.2.2. A reference distance and direction from a known location shall be provided. Where the culvert is located at a property access point, a stock underpass or fauna underpass, the title used on the Cover Sheet and detail sheets shall be in the format shown in Figure 32.2.3. A reference distance and direction from a known location shall be given. Where an existing reinforced concrete box culvert is to be extended, the title used on the Cover Sheet and detail sheets shall be in the format shown in Figure 32.2.4. The details of the existing culvert (year of construction, Bridge No and registration number of plans) shall be provided as shown in Figure 32.2.4 In all instances, the number of cells, together with the cell dimensions shall be provided as part of the title information.

32.3 GENERAL ARRANGEMENT DRAWINGS The General Arrangement suite of drawings for a culvert shall consist of a plan, longitudinal section (along the centreline of the culvert) and a view of the culvert perpendicular to the centreline of the culvert. A Datum Block, with a Datum Reduced Level and showing chainages, design surface levels and existing surface levels, shall be provided beneath the end view. The General Arrangement suite of drawings, where applicable, shall provide details of a typical joint between adjoining precast concrete crown units and details of any link slab connections. The General Arrangement suite of drawings shall also contain a table which provides the assumed precast concrete crown unit dimensions used in the design. The General Notes, in the General Arrangement suite of drawings, shall provide information with respect to the crown unit dimensions and the fill height to be used in the design of the precast concrete crown units as well as the number of standard crown units and end crown units required. Where precast reinforced concrete link slabs are used in the culvert design, the span and width dimensions of the link slabs, together with the fill height to be used in the design of the link slabs and the number of each type of link slab required, shall be provided in the General Notes. Where the size of the culvert requires that it be considered to be a bridge and therefore allocated a Bridge No (see Clause 32.1), the suite of General Arrangement drawings shall clearly show the location of the name plates that must be set flush with the finished concrete surface of the left hand side wing walls as viewed from each end of the culvert. The dimensions for the location of the name plates shall be given on the Wing Wall detail sheet. A typical suite of General Arrangement drawings is shown in Figures 32.3.1 and 32.3.2.



32.4 CAST-IN-PLACE BASE SLABS

Cast-in-place reinforced concrete base slabs shall be detailed to suit the assumed dimensions of precast reinforced concrete crown units provided on the General Arrangement drawing. Cast-in-place reinforced concrete base slabs shall be located by providing the co-ordinates of the inlet and outlet ends of the culvert on the centreline of the culvert. Reduced levels shall be provided at the inlet and outlet end of the base slab on the centreline of the culvert. The location and depth of recesses provided for the seating of precast reinforced concrete crown units shall be clearly shown in the cross section and reinforcement shall be detailed to suit. The General Notes on the cast-in-place base slab drawing shall contain the following note: “All concrete dimensions shall be checked and adjusted if necessary to suit the actual precast crown units used.” Cut-off walls shall be provided at both ends of the base slab. The reinforcement in the cast-in-place base slab shall be detailed in accordance with Section 23 of this Manual. A typical cast-in-place reinforced concrete base slab is shown in Figure 32.4.1. In some instances, cast-in-place base slabs may be required to have a nominal depth depression to provide an adequate means for aquatic life to pass through the culvert during periods of low flow. Such culverts are termed “fish friendly”. The method of detailing the concrete base slabs for “fish friendly” culverts is shown in Figure 32.4.2 and the method of detailing the reinforcement in such slabs is shown in Figure 32.4.3. Where culverts are designed to be used as a livestock underpass, the top surface of the base slab must be grooved diagonally in both directions to provide improved traction for livestock. Figure 32.4.4 shows an appropriate method of detailing a grooved surface on a base slab for a reinforced concrete box culvert that is used as a livestock underpass. It should be noted that increased cover to reinforcement is required in base slabs in livestock underpasses due to the acidic nature of livestock excrement that may be deposited during livestock movement. The use of contraction joints in culvert base slabs is optional unless specified by the designer or the client. A typical contraction joint detail is shown on Figure 32.4.1. Wing wall starter bars must be cast into base slabs. The number, location and shape of such bars shall be clearly detailed on the base slab drawing.

32.5 CAST-IN-PLACE APRON SLABS

Cast-in-place reinforced concrete apron slabs shall be provided at each end of all culverts used for the purpose of either a stock or fauna underpass. Where the base slab supporting the culvert has been detailed with a grooved surface to provide improved traction, the grooved surface shall be continued on the apron slab as well. Figure 32.4.5 shows a typical example of a grooved surface on Apron Slabs.



32.6 PRECAST REINFORCED CROWN UNITS

Generally, the dimensions of reinforced concrete crown units and end units shall not be shown where the units are shown on the drawings.. The assumed concrete dimensions for crown units and end units shall be given in table format on the General Arrangement drawing as shown in Figure 32.3.1.

32.7 CAST-IN-PLACE HEADWALLS

Cast-in-place reinforced concrete headwalls shall be detailed to suit the dimensions of precast reinforced concrete crown units and end units specified in the table provided on the General Arrangement drawing. Precast end crown units shall be shown on the drawing, with the protruding reinforcement clearly detailed to enable the correct placement of reinforcement in the headwall. Where the reinforcement in the headwall is designed to be lapped with reinforcement protruding from the precast reinforced concrete end crown units, this shall be clearly stated on the drawing. A typical Cast-in-Place Headwall drawing, for use on a culvert with a precast reinforced concrete link slab, is shown in Figure 32.7.1. A typical Cast-in-Place Headwall drawing, for use on a culvert without a precast reinforced concrete link slab, is shown in Figure 32.7.2.

32.8 CAST-IN-PLACE WING WALLS Cast-in-place reinforced concrete wing walls shall be detailed to suit the height of the fill above the culvert, the slope of the road embankment in the approaches to the culvert and the height of the cast-in-place reinforced concrete headwall. Particular attention must be paid to the setting out information for wing walls that is shown on the wing wall drawing. The setting out point for wing walls is the intersection point of the outside face of the wingwall and the outside face of the outer crown unit at the front face of the base slab. The location of name plates for bridge size culverts shall be clearly shown on the drawing or drawings. Typical details for cast-in-place reinforced concrete wing walls are shown in Figure 32.8.1.

32.9 INLET AND OUTLET PROTECTION

Where culverts are to be located at a defined watercourse or in areas known to be subject to flooding, consideration must given to protecting the area immediately adjacent to both the inlet and outlet end of the culvert against scour. The type and level of scour protection required at individual culvert sites shall be as directed by the client or a suitably qualified Hydraulic Engineer.



32.10 CULVERT EXTENSIONS Where an existing reinforced concrete box culvert is to be extended, the size of the

crown units used shall be such that the existing waterway area is not reduced.

The information to be shown in the General Arrangement suite of drawings shall be in accordance with Figures 32.10.1and 32.10.2 with particular reference being made to the sealing of the interface between the existing culvert and new culvert extension.

The base slab that is constructed to seat the additional crown units shall be connected to the exisiting base slab using stainless steel dowels at 300mm centres as shown in Figure 32.10.1. The downturn at the end of the existing concrete base slab in contact with the new concrete downturn shall be roughened. A sealant, complying with RTA Specification RTAB312, shall be used at the interface between existing work and new work as shown in relevant details on Figure 32.10.1. The drawing prepared to provide details of the cast-in-place base slab reinforcement drawing shall be in accordance with typical details as shown in Figure 32.4.1. The drawing prepared to provide details of cast-in-place wing walls shall be in accordance with typical details as shown in Figure 32.8.1. The drawing prepared to provide details of the cast-in-place headwall shall be in accordance with typical details shown in Figures 32.7.1 a or 32.7.2 as appropriate.

32.11 BAR SHAPES DIAGRAM

A suitable Bar Shapes Diagram shall be included in each set of drawings prepared for new culvert construction or culvert extensions.
