取芯钻孔需要多长时间? 3 决定时间表的关键因素

新闻 414 次

规划建设或翻新项目时, 客户经常问: “取芯钻孔需要多长时间?” 虽然时间表各不相同, 三个关键因素决定持续时间:

1. Project Scale Directly Impacts Work Hours

  • Small-scale tasks (例如, 2-3 HVAC holes for homes) typically take 2-3 hours.
  • Large projects (例如, 100+ rebar holes on construction sites) may require 3-5 日.
    Pro Tip: For every 10 additional holes in standard concrete walls, expect a 30% increase in total drilling time.

2. Depth Doubles Time for Every 10cm Increase

  • Common household holes (15-30cm depth): 15-30 minutes per hole.
  • Specialized deep drilling (1m+ depth): 2+ hours per hole.
    Critical Note: For reinforced steel layers or complex concrete structures, use a phased drilling approach to protect equipment and boost efficiency.

3. Hidden Factors That Delay Progress

  • Workspace constraints (narrow areas reduce efficiency by 40%)
  • Equipment quality (professional core drills work 3x faster than handheld tools)
  • Material hardness (reinforced concrete takes 50% longer than brick walls)
  • Operator expertise (experienced technicians save 20% time by predicting rebar locations)

Pre-Project Checklist for Faster Completion
① Provide accurate utility line blueprints
② Conduct pre-drilling hardness tests
③ Clear 2 meters of workspace around drilling areas

Case Study: 钻探 10 holes (30cm depth) takes professional teams 2 hours less than unskilled crews. Teams using infrared positioning systems avoid damaging hidden pipes, eliminating rework delays.

For precise quotes and timelines, request an on-site evaluation. Professional assessments account for local conditions to optimize your schedule and costs.
