Corrosion and Abrasion Measures

Galvanized in accordance with ASTM-123

Design corrosion rates conform with AASHTO & FHWA-RD-89-186 metal loss rates

Minimal abrasion in 50/6 soil (WSDOT)

4Fe+3O2+4H2+8H+= 2(Fe2O3•H2O)+2OH2O+8H+

Slide 2.1 Concrete vs. Helipost

The Problems with Concrete:

Complicated - Labor intensive and equipment heavy, with multiple crews necessary to complete the installation process.

Expensive – Inefficiencies due to the common logistical challenges, materials, and equipment used for concrete installation add both time and money to the project costs

Slow – The curing period required before concrete piers and anchors are ready to accept the above-ground unit adds days or weeks to project schedules.

Common Helipost Applications

UASUniversal Anchoring Solutions

Slide 3.1 Common Helipost Applications

Introduction: Helipost Applications

Sound walls and noise barriers

Solar panels (ground mounted)

Highway signs

Light posts

Security walls

Cell towers (mono pole)

Steel buildings

Billboards

UASUniversal Anchoring Solutions

Helipost delivers 20 tons of axial load, therefore:

Supports walls up to 30 feet Supports high-mast lights up to 100 feet Supports large exit signs and cantilever lights Supports mono-pole cell towers Anchors even large solar panels

Slide 3.2 Common Helipost Applications

Performance Means Multiple Applications

UASUniversal Anchoring Solutions

Overview of the Helipost Site Engineering Process

Step 1 – Geotechnical ExplorationCategorize major soil units and determine index properties

Method A: Group soils according to soil classificationMethod B: Determine soil index properties through extensive field and laboratory testing

Step 2 – Wind LoadsDetermine shear and overturning moment based on structural attributes

Method A: Use AASHTO or ASCE7 wind chartsMethod B: Hand calculate wind loads using desired method (see appropriate code)

Step 3 – Helipost SizingDetermine required foundation size for wind loads

Method A: Refer to Helipost sizing charts for the appropriate soil categoryMethod B: Apply rigorous limit state and p-y analysis and check foundation strength

Step 4 – Bearing CapacityCalculate weight of structure to be supported and capacity of foundation

Method A: Refer to Helipost baring capacity charts for appropriate soil categoryMethod B: Calculate bearing capacity using traditional soil mechanics

Step 5 – Corrosion MeasuresRe-adjust sizes if needed to account for corrosion losses over design life

Method A: Observe corrosion chart and adjust size for corrosion category by matching moment and shear while maintaining or increasing sizeMethod B: Determine corrosion losses and adjust
