A66 Salzbachtal Bridge, Germany

The A66 Salzbachtal Bridge, located in Wiesbaden, Hesse, is a 304-meter-long, four-lane motorway bridge on the A66. Originally constructed in the mid-20th century, the bridge has been subject to wear and tear due to increasing traffic loads and aging infrastructure.

Foundation piles are fundamental to the stability and longevity of bridge structures. Ensuring their integrity is crucial to preventing potential structural failures. dextra played a pivotal role by supplying approximately 10,000 linear meters of Sonitec CSL (Cross Sonic Logging) tubes.

Sonic tubes are essential components in the CSL testing method, which is widely regarded as one of the most reliable techniques for assessing deep foundation integrity. Sonitec, designed for easy installation within the reinforcement cage, facilitates accurate cross-hole sonic logging, allowing engineers to precisely detect and locate defects within the piles.

Cross Island Line (CRL) MRT, Singapore

dextra has played a pivotal role in the construction of Singapore’s Cross Island Line (CRL) MRT project, supplying Glass Fiber Reinforced Polymer (GFRP) soft-eyes, bartec couplers and Barras con cabeza for several crucial packages. dextra continues to support the ongoing packages of this extensive project.

The CRL is set to become Singapore’s eighth MRT line and its longest fully underground line, stretching over 50 kilometers. The project is being executed in three phases, with the first phase anticipated to be operational by 2030.

To minimize the environmental impact on the forested areas of the nature reserve, engineering solutions were meticulously chosen to further mitigate environmental disruption. These solutions include digging deeper into the ground and employing a large diameter boring machine, capable of accommodating two train tracks within a single tunnel. This approach not only reduces the surface footprint but also enhances the efficiency of the tunneling process.

Tunnel Boring Machines (TBMs) are a staple in Singapore’s subterranean infrastructure projects, adept at operating under a variety of ground conditions. The use of GFRP soft-eyes supplied by dextra is integral to these operations. Soft-eyes are essential components in TBM tunneling, acting as temporary openings that allow the TBM to break through concrete walls without compromising structural integrity. The GFRP material is preferred for its high strength-to-weight ratio, corrosion resistance, and ease of installation, ensuring safe and efficient tunneling operations.

dextra‘s expertise and reliable supply of GFRP soft-eyes, bartec couplers and headed bars have significantly contributed to the progress of the CRL project, aligning with Singapore’s commitment to sustainable and innovative infrastructure development. As the CRL project advances, dextra remains a key partner, supporting the construction of this monumental MRT line that will eventually enhance the daily commute for millions of Singaporeans.
