Pre-construction Preparations
Pile driving for guardrails is not something you can just jump right in. Good preparation can double construction efficiency:
Site Survey: First, understand the geological conditions; soft soil and hard rock require different approaches.
Layout and Positioning: Use a total station or steel ruler to accurately mark the pile positions, with a deviation not exceeding 5cm.
Equipment Inspection: Hydraulic oil, diesel fuel, and wire rope are all essential; test the machine for 30 minutes beforehand.
Material Acceptance: The length error of the guardrail piles must be controlled within ±2mm.
Core Techniques for Pile Driving Operation
Mastering these tips will transform your pile driver into a "steel pangolin":
Verticality Control: Use a two-way level to maintain the pile body at 90°. 0° Vertical Installation
Segmented Driving: When encountering hard soil layers, each downward press should not exceed 50cm.
Shock Reduction Tips: Installing rubber pads on the pile top can reduce noise by 30%.
Abnormal Handling: If pile misalignment occurs, stop the machine immediately and use jacks to correct it.
Key Points for Completion and Acceptance: Don't assume everything is done after pile driving; these finishing touches determine the success or failure of the project:
Height Verification: Use a level to measure; the height difference between adjacent piles should be ≤3mm.
Corrosion Protection: Welded joints must be coated with anti-rust paint; the coating thickness should be ≥200μm.
Site Cleanup: Collect all metal scrap to avoid the risk of punctures.
Impact Test: Randomly select 5% of pile locations for impact resistance testing.
