Rising Bollard Installation Best Practices: From Site Survey to Commissioning

Step 1: Site Survey Before Installation

A successful bollard installation starts with a thorough site survey. Verify the following before any excavation begins:

• Underground utilities: locate water pipes, cables, and gas lines at the installation point; a shallower model may be required where deep excavation is impossible
• Soil conditions: confirm that the ground can support the concrete foundation required by the model
• Drainage direction: identify where water collects and where the drain line will connect
• Power availability: confirm 220 V supply reachable from the control cabinet location
• Control cabinet position: plan the wiring path between bollards, the control cabinet, and signal interfaces

Step 2: Foundation Excavation

Foundation depth depends on the bollard type. Automatic bollards require a deep foundation, while shallow-mount models are designed for restricted sites.

Excavate to the exact size shown in the installation drawing, pour the concrete foundation, and allow it to cure fully before mounting the bollard. A foundation that is too small or not fully cured is the most common cause of bollard movement and premature failure.

Step 3: Drainage

Water inside the pit is the enemy of every bollard. Install a proper drainage system:

• Lay a gravel drainage layer at the bottom of the pit so water can flow away from the bollard body
• Connect the pit drain to a drainage pipe leading to the storm system, with sufficient slope to let water flow out
• Install a check valve to prevent groundwater from flowing back into the pit
• In areas with a high water table, add an automatic sump pump inside the pit
• Use sealed cable entries so water cannot enter through the wiring

Step 4: Electrical Wiring

Correct wiring is essential for reliable and safe operation:

• Power supply: standard automatic bollards operate at 220 V; confirm the model rating before connecting
• Control voltage: the control system uses a 24 V control voltage, which is safer and more stable for signal lines
• Control cabinet: mount the cabinet in a dry, accessible location, rated for outdoor dust and water protection (IP66 for intelligent control systems)
• Wire protection: route power and signal cables in protective conduit buried below ground, never exposed
• Earth connection: connect the ground terminal of every bollard to the earth bus of the control cabinet
• Signal interfaces: reserve the interfaces for card readers, ground loop detectors, and license plate recognition equipment during installation so integration is easy later

Step 5: System Commissioning

Commissioning verifies that every bollard operates correctly. Follow this sequence:

Single-channel commissioning

Test one bollard at a time: raise and lower it manually, then by remote control, and check the warning light and reflective tape. Verify that the rise time matches the specification (for example, 3-5 seconds for automatic models, no more than 4 seconds up and 2 seconds down for the hydraulic model).

Two-channel and multi-channel commissioning

For installations of two or more bollards, test the group control: all bollards must rise and lower in synchronization. Check the group separation function, where different groups respond to different control signals. For multi-channel systems controlling 18 bollards or more, verify each group independently and confirm the emergency lowering module works for all channels.

Emergency functions

Test the emergency stop and emergency lowering. If the system has an EPS emergency power module, simulate a power failure and confirm that all bollards lower safely. This is the most important safety check in the whole installation.

Step 6: Final Acceptance Checklist

• All bollards rise and lower fully, without hesitation or noise
• Rise and lower times match the model specification
• Warning lights and reflective markings work correctly
• Control cabinet indicators match the actual bollard positions
• All control methods work: manual, remote control, card reader, and external signals
• Drainage works: no water accumulates in the pit after rain or washing
• Emergency stop and emergency lowering verified under test conditions
• Site restored cleanly, with no trip hazards around the bollards
• Installation drawings, wiring diagram, and test records handed over to the owner

When every item on this list passes, the installation is complete and the system is ready for daily operation.

"A bollard is only as reliable as its installation. Correct foundations, drainage, and wiring turn a good product into decades of dependable service."
