Xinjiang - Tianshan Shengli Tunnel Project

Project Overview

• Location: Xinjiang, Wuwei Expressway, Tianshan Shengli Tunnel

• Altitude: 2,700 meters

• Tunnel Type: Two-lane highway tunnel

• Total Length: 22,000 meters

Project Requirements

To ensure efficient excavation, multiple air compressors were deployed along the tunnel. The goal was to provide sufficient compressed air for rock drilling while optimizing energy consumption.

Aivyter Solution

To improve energy efficiency, Aivyter Smart Compressor AWT-10 was integrated into the air supply system at key locations.

1. Phase 1: Pilot Tunnel to Main Tunnel (4,100m)

• Initial Setup: 7 × 132KW (24m³) air compressors

• Excavation Progress: By 4,700m, all 7 compressors were running, powering 18 × 28 pneumatic rock drills

• Optimization: SYC Portable Diesel Engine Screw Air Compressor deployed 200m from the tunnel face

• Result: Only 4 compressors needed to run, achieving full air supply requirements

• Energy Savings: Reduced usage of 2 × 132KW air compressors

2. Phase 2: Pilot Tunnel to Main Tunnel (7,000m)

• Initial Setup: 7 × 132KW (24m³) air compressors

• Excavation Progress: By 7,600m, all 7 compressors were running, powering 18 × 28 pneumatic rock drills

• Optimization: Portable Diesel Engine Screw Air Compressor deployed 200m from the tunnel face

• Result: Only 4 compressors needed to run, fully meeting excavation demands

• Energy Savings: Reduced usage of 2 × 132KW air compressors

Energy Efficiency & Cost Savings

By reducing 4 × 132KW compressors, the project achieved significant power savings.

• Estimated Annual Savings:
  132KW × 10 hours/day × 365 days × 4 compressors = 1,927,200 CNY/year (Based on 1 CNY per kWh)
