Open-minded innovation

Benefits for specifiers

ACO Brickslot is one result of over 30 years’ experience in the development of innovative surface drainage solutions for highways, local authority, retail, commercial and domestic users.

ACO Brickslot® has been specifically designed to reduce installation time and provide inexpensive maintenance over its whole life.

Discreet high performance channel drainage fully compatible with paviours, setts, blocks or flags in pedestrian, driveway or medium traffic loading areas to Load Class C (BS EN 1433:2002). The channel system comprises a slotted steel cover frame, with a locking device, fitted over a channel drain unit to form an integrated channel drainage system.

ACO Brickslot® may be unobtrusively positioned at paving joints, providing a virtually uninterrupted appearance.

ACO Brickslot® offers cost advantages for architects, engineers, contractors and clients.

Free technical support

10mm wide inlet slots provide heel protection. Complies with BS EN 1433:2002 for pedestrian areas.

Flared inlet slot minimises the risk of blockage.

Lower costs

To support architects, engineers and contractors in designing and installing ACO Brickslot® schemes, ACO’s Design Services Team offers computer-aided scheme design, hydraulic performance calculations and installation advice services.

Benefits for contractors

ACO Brickslot速 CHANNEL DRAINAGE

Hydraulic choices with ACO Brickslot速 1. Constant Invert, Level Ground

- effective drainage but may need more regular maintenance due to greater chance of silting. 2. Constant Invert, Sloped Ground

- improved hydraulic capacity over system 1.

3. Sloping Invert, Level Ground

- 0.5% invert slope provides positive drainage for petrol or chemicals etc. 4. Sloping Invert, Sloping Ground

- improved hydraulic capacity over 3.

5. Stepped Invert, Level Ground

- will give a similar hydraulic capacity as sloping invert 3.

ACO Brickslot® INNOVATION IN APPLICATION

ACO Brickslot® is a subtle and unobtrusive drainage system, yet offering high hyraulic efficiency in paved areas. Ideal for shopping precincts, pedestrian areas, hotels, commercial and public buildings.

ACO Brickslot® is compatible with most pre-cast paving materials, and the vertical sides enable pavements to be laid directly to the unit’s edge.

Brickslot access covers are unobtrusive.

ACO Brickslot® is not vulnerable to vandalism or loose grates. Rodding access units and the universal sump units ensure easy maintenance.

ACO® Brickslot channel cover, 10mm flared slot.

ACO Brickslots® is discreet and, with all fixings below surface, is suitable for school or play area installations. ACO® Brickslot access cover frame, 10mm flared slot.

ACO Brickslot® HYDRAULIC PERFORMANCE TABLES

Channel Capacity: An explanation and use of the Hydraulic Performance Tables Introduction The determination of the hydraulic capacity of surface water channels is not a simple calculation. It is inappropriate, for instance, to apply formulae such as Manning, or Colebrook-White, or similar, because these equations are applicable only to steady, uniform flows. Using uniform flow equations with ground slopes that are level, or nearly level, a flow velocity or cross sectional channel area will be very severely under or over estimated respectively. With steep slopes the velocity will be overestimated and the cross sectional area underestimated. In the case of channels, and although the flow is steady, the depth and velocity of flow will vary gradually along the length of the channel – and the flow therefore is non-uniform. For steady, non-uniform flows, channel capacities can be calculated accurately only by applying and solving spatially varied flow equations. Recourse to a computer program to predict accurately the flow capacity in channels, using these equations, is necessary. Over twenty years ago ACO, following extensive full scale laboratory testing and validation via a 30 metre length of channel, developed a computer program to solve the differential equations for steady non-uniform flows. The program is capable of calculating channel capacities of complex and varied layouts – for example where the ground and/or channel invert gradients/depths vary or where the area draining into the channel is irregularly shaped or, in internal applications, where discharges from machines occur or the channel layouts are interconnected. Definitions Rainfall intensity [l/s/m2] : The rainfall intensity [i] is a function of the location, and the duration and return frequency of a storm. For areas that can tolerate ponding for a short period following the end of a storm then [i] may be assumed to be 0.014l/s/m2 (50mm/h).

Catchment Area [m2] : The area [CA] drained by a channel(s). Catchment Length [m] and Depth [m] : The catchment length [CL] is assumed in the direction of the channel run. Catchment depth [CD], measured on plan at right angles to the channel, is the distance over which surface water drains to a channel. A channel may be positioned anywhere within the catchment depth. Lateral Inflow [l/s/m] : The lateral design inflow to a channel per metre length [q] and equals rainfall intensity x catchment depth. End Inflow [l/s] : An inflow directly into the upstream end of a channel run. End inflow may result from a pipe connection or another channel or from pre-cast concrete kerb channels draining an area upstream of a channel run. Length to Outlet [m] : The length of channel [Lo] draining to an outlet. Design Flow [l/s] : The calculated total runoff [Qd] from a catchment area. Flow Capacity [l/s] : The maximum flow capacity of a channel [Qmax] is reached when the maximum flow depth equals the design channel depth. The position of maximum flow depth will vary with the longitudinal ground slope. A channel installed in level ground has the maximum flow depth at the start of the run; in sloping ground the maximum flow depth occurs somewhere downstream towards the outlet. The tables indicate the maximum catchment depth (lateral inflow, CD) for a given length of channel to an outlet [Lo]. CD may be adjusted pro-rata for other rainfall intensities. The catchment depth, and hence the lateral inflow, is assumed to be uniform over the length of the channel run. Four ground slopes are given and interpolation of the data is possible. For lengths to an outlet and ground slopes outside the ranges shown, or if technical assistance is required, please contact ACO’s Design Services department.

The maximum Catchment Depth drained by channel may be derived from the tables. Given Total flow (Q) in l/s; Catchment Depth (CD) in metres; length to channel outlet (Lo) in metres and rainfall intensity (I) of l/s/m2 then Q = CD x Lo x I : Hence Catchment Depth.

6 Note: The hydraulic data tables are based on the capacity of the channel and assume that the capacity of the inlet slot is adequate.

ACO Brickslot速 INSTALLATION

1.0 Ground Conditions The customer should ensure that the minimum dimensions shown are suitable for the existing ground conditions. Engineering advice may be necessary.

Block pavement: access frame Paviours directly adjacent to frame to be bedded using a polymer modified mortar or similar, see note 2.0

Specified Paviours to be set into Brickslot Access Frame using a polymer modified mortar or similar, see note 2.0 Paviour

Paviour

2.0 Block Pavements

Sand Bed

The channel must be supported laterally and therefore blocks must be restrained from movement by bedding securely e.g. by using a Polymer Modified Mortar for bed and perpendicular joints (for example RONAFIX Mortar Mix C from Ronacrete: Tel 0208 593 7621). Engineering advice may be required.
