Box jacking: What is at stake?

Building a 100-meter long road tunnel, under an existing tunnel and doing it all without interrupting the flow of the top tunnel: 3 huge challenges – all in one.

Box Jacking is a trenchless method of construction that allows for these incredible feats of engineering.

How VSL can help you

Box jacking is the only solution able to address this kind of project.

Box jacking, while being safe and efficient, is ideal for dense environments, meets tight construction deadlines and provides life-long durability advantages. It requires a hydraulic jack system that pushes prefabricated tunnel segments through the ground and into place.

VSL – Intrafor successfully completed many of the world’s first box jacking projects, like Hong Kong’s Link Road 3 – which runs under the Airport Express Link (AEL).

VSL utilises its heavy lifting and geotechnics and heavy lifting and sliding expertise and engineering know-how to develop and deliver comprehensive box jacking solutions – from design all the way to project execution.
