TUNNEL JACKING: A VERSATILE TECHNIQUE

This article reports presentations at a recent meeting about a range of projects involving the construction of underground jacked structures; future prospects were also examined. T Walters introduced the meeting, explaining that projects would be described, which are characterised by construction of permanent tunnel linings adjacent to their final positions, in component or in-situ form, and their subsequent slow movement into position by means of hydraulic jacks with simultaneous excavation at the face. C Howe showed how pipe jacking had been developed to provide an alternative method of constructing bridges and tunnels, at sensitive locations where disruption during installation needed to be minimised. He gave illustrative examples from the UK, India, and Canada. T Walters described five successively larger and more complex tunnel jacking projects, undertaken by Mott MacDonald in the UK, Indonesia, Australia, Taiwan, and the USA. He saw each project as an opportunity to innovate, and predicted four specific further developments. T Steven gave his personal opinions on the role that Railtrack should have in tunnel jacking projects for railways in the UK. He considered that enough control could be exercised by a skilled and resourced Railtrack team fulfilling its objectives without managing the work at first hand.
