The Modern Tunnel Boring Machine (TBM)

The Tunnel Boring Machine (TBM) is a key player in the deep tunneling process. Designed for efficiency, it can excavate tunnels of varying diameters ranging from 2 meters to over 15 meters, depending on project requirements. For instance, our latest project utilized a TBM to construct a 4.5-kilometer utility tunnel in just 18 months, showcasing an impressive completion rate of 250 meters per week. This technology not only enhances speed but also maintains structural integrity and minimizes ground disturbance.

Sequential Excavation Method (SEM)

The Sequential Excavation Method (SEM) is a flexible tunneling technique that is particularly effective in urban areas. By excavating and supporting the tunnel in stages, SEM allows for adaptive responses to varying geological conditions. This method has been employed successfully in Singapore’s MRT expansion project, where we implemented SEM to navigate through complex ground conditions, achieving a success rate of over 90% in maintaining schedule adherence despite encountering unforeseen challenges.

New Austrian Tunneling Method (NATM)

The New Austrian Tunneling Method (NATM) emphasizes the importance of the surrounding rock as a supporting element. This technique has been vital in Singapore’s deep tunneling projects, where rock stability plays a critical role. By utilizing NATM, we have reduced construction costs by approximately 15% while accelerating project timelines. Our teams have employed this method to create over 30 kilometers of tunnels for various transport systems, showcasing its versatility and effectiveness.

Cut-and-Cover Method

The Cut-and-Cover Method involves excavating a trench, constructing the tunnel base, and then covering it to restore the surface. This technique is especially useful for shallower tunnels and has been effectively utilized in Singapore’s utility networks. Our projects employing this method have exhibited a completion time reduction of up to 20% compared to traditional tunneling methods, allowing for quicker integration of essential services like water and electricity while minimizing community disruption.

Microtunneling for Precision

Microtunneling is a trenchless technology ideal for installing small-diameter pipelines with high precision. This method minimizes surface disruption and is suitable for urban environments. Our implementation of microtunneling in recent projects has resulted in a 98% success rate for alignment and a significant reduction in excavation-related impacts, demonstrating our commitment to sustainable tunneling solutions in Singapore’s densely populated areas.
