In urban underground pipeline construction, the cost differences between trenchless HDD vs open-cut methods extend far beyond initial investments, impacting the entire project lifecycle. This analysis examines the comprehensive cost advantages of trenchless HDDvs open-cut technologies from an engineering economics perspective.

1. Direct Cost Optimization Advantages

Compared to traditional open-cut methods, trenchless HDD vs open-cut technology reduces costs through:

(1) Earthwork savings: Eliminates excavation, backfill and compaction processes, reducing earthwork volume by 60%+

(2) Pavement preservation: Avoids asphalt/concrete damage and subsequent repair costs

(3) Labor efficiency: Modern equipment like HWF50 requires only 3 operators (50% labor reduction)

(4) Schedule compression: Achieves 35-50m daily progress (HWF50 max. construction distance: 100m)

2. Hidden Cost Avoidance Benefits

Trenchless HDD vs open-cut technology prevents common open-cut cost risks:

(1) Traffic control: No road closures or detour expenses

(2) Business compensation: Eliminates merchant revenue loss claims

(3) Weather resilience: 40% more annual productive workdays

(4) Utility protection: ±10cm guidance accuracy (HWF50 spec) prevents existing line damage

3. Long-Term Maintenance Advantages

Pipelines installed via trenchless HDD vs open-cut demonstrate superior lifecycle economics:

(1) Depth assurance: 16-20° entry angle capability (HWF50 parameter)

(2) Corrosion resistance: Joint-free installation reduces maintenance

(3) Geological stability: 2255N·m torque ensures borehole integrity

(4) Extended service life: HDPE pipes can last 50+ years

4. Hengwang HWF50 Cost-Efficiency Features

As a professional trenchless HDD vs open-cut solution, HWF50 incorporates:

(1) Fuel efficiency: 42.2kW Yanmar engine with smart ECO mode

(2) Drill pipe durability: 44 standard φ62mm rods (30% longer lifespan)

(3) Borehole quality: 75L/min mud pump flow ensures efficiency

(4) Compact design: 3800×1300×1800mm dimensions for tight spaces

Documented trenchless HDD vs open-cut project results:

(1) Penang Water Supply Project: 42% total cost reduction

(2) Dubai Telecom Pipeline: 35% maintenance savings

5. Project Selection Guidance

Trenchless HDD vs open-cut advantages magnify when:

(1) Crossing high-value areas (commercial districts, heritage sites)

(2) Existing utility congestion exists

(3) Challenging geology (soft soil, high water table)

(4) Tight schedules apply
