Project Background

A rapidly growing metropolitan city in Southeast Asia faced critical challenges with its aging sewer infrastructure. The municipal water authority required installation of a new 1.2km sewer pipeline through a densely populated urban area, passing beneath major roadways, existing utility networks, and commercial buildings. Traditional open-cut excavation was deemed impractical due to severe traffic disruption, environmental concerns, and the presence of sensitive underground utilities.

Key Challenges:

  • Installation depth ranging from 6m to 12m below ground surface
  • Navigation through complex geological conditions including soft clay, sandy soil, and mixed ground
  • Strict alignment tolerances (±30mm) required for gravity sewer flow
  • Proximity to existing underground utilities (gas, water, telecommunications)
  • Minimal surface disruption in high-traffic commercial district
  • Environmental regulations limiting noise and vibration levels

Solution: Advanced Slurry Pipe Jacking Machine System

APIE Foundation Equipment (China) Limited provided a comprehensive trenchless solution featuring our HYPERTEC  Pipe Jacking Machine, specifically designed for urban infrastructure projects requiring precision and minimal surface impact.

Technical Implementation

Phase 1: Site Preparation & Launch Shaft Construction

  • Construction of 8m diameter launch shaft using diaphragm wall technique
  • Installation of thrust frame and hydraulic jacking system
  • Setup of slurry separation and recycling plant

Phase 2: Pipe Jacking Operations

  • Installation of 1500mm internal diameter concrete jacking pipes
  • Average advance rate: 8-12m per day
  • Real-time laser guidance system maintained alignment within ±25mm
  • Continuous slurry circulation system for spoil removal and face support

Phase 3: Reception & Connection

  • Precise breakthrough at reception shaft
  • Pipeline connection to existing sewer network
  • Shaft reinstatement and surface restoration

Project Results

✅ Successful Completion: 100% alignment accuracy achieved, exceeding project specifications
✅ Minimal Disruption: Surface traffic maintained throughout 8-month project duration
✅ Environmental Compliance: Zero environmental incidents, noise levels maintained below 65dB
✅ Cost Efficiency: 30% cost reduction compared to traditional open-cut methods
✅ Time Savings: Project completed 2 weeks ahead of schedule
