Release time:
2025-12-24
Abstract
Construction unit: China Construction and Japan’s Taisei Corporation
Device Number: ("China Railway No. 1108" Tunnel Boring Machine) China Railway Equipment
Cutting disc diameter: 12.66 meters
Tunneling length: 3,157 meters
Project Features:
A benchmark for technological breakthroughs in Singapore’s metro sector: This is the first metro construction project undertaken by Singapore’s Land Transport Authority to employ a large-diameter tunnel boring machine, marking a departure from traditional methods of subway tunnel construction locally. The geological and environmental challenges during construction are exceptionally high: the tunnel must pass through a variety of complex geological formations, including marine clay, mixed granite, and old impact sand layers, with highly variable geological conditions. At the same time, the tunnel needs to run beneath Changi Airport—a major international transportation hub—as well as other critical structures, placing extremely high demands on construction settlement control and equipment stability. Throughout the construction process, it is imperative to strictly avoid any adverse impacts on surrounding key facilities.
