Drainage Report

Introduction

• 1. Axis Consulting Engineers were requested to provide design services on a proposed distribution centre at Eden Park, Cooil Road.
• 2. This report provides drainage calculations justifying the proposed design.
• 3. The following is included:

• a. Hydraulic modelling for the site (undertaken in Causeway Flow)
• b. Linear drains calculations (undertaken using ACO software)
• c. Strength of proposed attenuation crate system (undertaken by ACO design team)

• 4. The site drains into sewers for both foul & surface water. These connections are provided up the new spine road, and are delivered by others.
• 5. The maximum discharge rate for surface water flows has been agreed at 8.8 l/s (through a Hydrobrake), with excess flows to be contained within on site attenuation. Surface water flows are ultimately discharged back into Middle River.
• 6. Foul flows are collected into the carrier sewer and lead to a pumping station. Foul flows are relatively light (welfare/office facilities, lorry wash), and gradients are in line with Approved Document H (150mm at 1:80 circa 20l/s), therefore detailed hydraulic modelling has not been undertaken.
• 7. Drainage modelling on site has checked for the 2 year, 30 year and 100 year design events. 40% climate change allowance has been appraised. There is no flooding on the site in this scenario, with surcharging of the drainage system deemed acceptable.
• 8. This report should be read in conjunction with drainage drawings 2510-AXS-DR-1301 & 2510-AXS-DR-1302, in addition to other project drawings and specifications for the site.

• *ACO would typically suggest flow velocities of 0.7m/s or greater in channels to be considered self-cleansing velocities. Flow velocities in the upper reaches of linear drainage systems are not likely to achieve self-cleansing velocities.
• **The flow in this channel varies betwen sub-critical and super-critical conditions so the depth / velocity calculation is not precise. However, your selected channel will have sufficient capacity to accomodate the defined flow. Note that optimised solutions will only suggest non-turbulent, sub-critical flow regimes.

**The flow in this channel varies betwen sub-critical and super-critical conditions so the depth / velocity calculation is not precise. However, your selected channel will have sufficient capacity to accomodate the defined flow. Note that optimised solutions will only suggest non-turbulent, sub-critical flow regimes.

Distrib. Load from vehicles (from table 4.2) = 10.0 kN/m2 Partial load factor for loading = 1.60 Traffic load = load x factor = 10 x 1.6 = 16.0 kN/m2 Total load = 27.7 + 16 = 43.7 kN/m2 Material factor of safety = 2.75 So design load = total load x material factor = 43.7 x 2.75 = 120.1 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

Wheel load

Wheel load 100kN on a 200mm x 600mm area (from Table 4.2) Load spread angle (a) = 38.21 degrees Cover depth = 0.915 m Tan a = Tan (38.21) = 0.790 m Loaded area = [(2xdepthxTana)+ tyre area 1] x [(2xdepthxTana)+ tyre area 2]

= [(2 x 0.92 x 0.79) + 0.2] x [(2 x 0.92 x 0.79) + 0.6] = 3.367 m² Distributed wheel load on top of tank will be 100 ÷ 3.367 = 29.7 kN/m² Partial factor for loading = 1.60 Material factor of safety = 2.75 Design load = 29.7 x 1.6 x 2.75 = 130.7 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

Surcharge load + Wheel Load

Total load could be surcharge soil load plus wheel point load

From above, design soil load is 21.6 x 0.915 x 1.4 x 2.75 = 76.1 kN/m2 From above, wheel point load is 29.7 x 1.6 x 2.75 = 130.7 kN/m2

• Total of surcharge load + point wheel load = 76.1 + 130.7 = 206.8 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

Distrib. Load from vehicles (from table 4.2) 10.0 kN/m2 Partial load factor for loading 1.60 Traffic load = load x factor = 10 x 1.6 = 16.0 kN/m2 Total load = 27.7 + 16 = 43.7 kN/m2 Material factor of safety = 2.75 So design load = total load x material factor = 43.7 x 2.75 = 120.1 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

= [(2 x 0.915 x 0.787) + 0.2] x [(2 x 0.915 x 0.787) + 0.6] = 3.347 m2 Distributed wheel load on top of tank will be 100 ÷ 3.347 = 29.9 kN/m2 Partial factor for loading = 1.60 Material factor of safety = 2.75 Design load = 29.9 x 1.6 x 2.75 = 131.5 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

Surcharge load + Wheel Load

Total load could be surcharge soil load plus wheel point load

From above, design soil load is 21.6 x 0.915 x 1.4 x 2.75 = 76.1 kN/m2 From above, wheel point load is 29.9 x 1.6 x 2.75 = 131.5 kN/m2

• Total of surcharge load + point wheel load = 76.1 + 131.5 = 207.5 kN/m2 Compressive strength of ACO StormBrixx = 455.0 kN/m2

Worst case will be with maximum depth of cover + vehicle loading

Lateral backfill internal angle of friction F'crit = 26.00 degrees Ground slope angle beyond tank extent b = 0.00 degrees Active earth pressure coefficient Ka = Tan2(45-F'crit/2)/(1-Sinb)

= Tan2 ( 45 - 26 / 2 ) / ( 1 - 0 ) = 0.390 Density of lateral backfill soil = g1 = 18.00 kN/m3 Calculation allows for the case where ground water level may be above the invert of the tank Then submerged density of lateral backfill soil g2 = g1 - 9.81 = 8.19 kN/m3

Soil Load

Depth of lateral backfill soil for earth pressure calc = tank height - 200mm

= 1.224 - 0.2 = Z = 1.024 m Depth of soil for earth pressure calculation above ground water level = Z1 = 1.024 m Depth of soil for earth pressure below ground water level = Z2 = 0.000 m

Average bulk weight for material above tank accounting for submerged soil g3 = 21.60 kN/m3 Maximum depth of material above tank Z3 = 0.915 m

Partial load factor = 1.35 Applied soil pressure = Ka x (g1Z1 + g2Z2 + g3Z3) x factor

= 0.39 x (18 x 1.024 + 8.19 x 0 + 21.6 x 0.915) x 1.35 = 20.1 kN/m2 Vehicle surcharge load = q = 10.0 kN/m2 Partial load factor = 1.50 Applied vehicle pressure = Ka x q x factor = 0.39 x 10 x 1.5 = 5.9 kN/m2 Material factor of safety = 2.75 Design load = (applied soil pressure + applied vehicle pressure) x Material factor

= (20.1 + 5.9) x 2.75 = 71.5 kN/m2

Hydrostatic load

Depth of water above base of tank - 0.2m 0.000 m Water pressure = density (1.0) x depth of water x g = 0.0 kN/m2 Design load = Applied pressure x Load factor x Material factor

= 0 x 1.35 x 2.75 = 0.0 kN/m2

Total lateral load = soil load + hydrostatic load = 71.5 kN/m2 Laterial strength of ACO StormBrixx = 95.0 kN/m2

There are three possible scenarios: water level below, part way up or over the tank From the data given at the head of this calculation, the case is water level below the tank

Depth of water displaced = 0.000 m Uplift force = depth of water displaced x buoyancy = 0 x 9.81 = 0.0 kN/m2 Partial factor of safety for uplift = 1.50 Design uplift force = Uplift force x factor = 0 x 1.5 = 0.0 kN/m2

Density of soil cover = 21.60 kN/m3 Effective density of submerged soil cover = 21.6 - 9.81 = 11.79 kN/m3 Minimum cover level (above datum) = 0.915 m StormBrixx invert level (above datum) = -1.224 m StormBrixx height = 1.224 m StormBrixx soffit level = invert level + height

= -1.224 + 1.224 = 0.000 m Groundwater level (above datum) = -10.000 m Minimum cover thickness = 0.915 m Depth of submerged soil = groundwater level - soffit level (up to minimum cover thickness)

= (-10 - 0) [max 0.915, min 0] = 0 m Depth of dry soil = minimum cover depth - submerged depth = 0.915 - 0 = 0.915 m Weight of dry soil (at minimum cover depth) = dry depth x dry density = 0.915 x 21.6 = 19.8 kN/m2 Net weight of submerged soil (at minimum cover depth) = submerged depth x submerged density = 0 x 11.791 = 0.0 kN/m2 Total net soil weight = dry weight + net submerged weight

= 19.8 + 0 = 19.8 kN/m2 Partial factor of safety for soil= 0.95 Design pressure = weight of soil x factor = 19.8 x 0.95 = 18.8 kN/m2 Design Pressure must be greater than Design Uplift = 0.0 kN/m2

Deflection of ACO StormBrixx is 1mm for every 50kN/m2 applied pressre Serviceability limit state factor of safety = 1.5 So design deflection parameter is 1.5mm for every 50kN/m2 applied pressure

From above calcs for vertical loads (at shallowest cover) Pressure from wheel loads on the top of the tank = 29.7 kN/m2 For serviceability analyses the factor of safety on live loads is 1.0 This is a live load so the design load is 29.7 x 1.0 = 29.7 kN/m2 Deflection of the tank = 1.5 x (29.7 ÷ 50) = 0.89 mm

General Notes

• 1. The load category of "Low speed roads (< 15 mph) (Articulated HGV GVW < 60T)" has been used based on given information; if this is unsuitable please advise a more suitable load category.
• 2. A load spread angle of 38.21 degrees has been assumed for vertical load distribution
• 3. The lateral load calculations have assumed a backfill with minimum internal angle of friction of 26 degrees and a maximum bulk weight of 18kN/m3.
