Meeting challenges under pressure
14 November, 2011
Traditional compressed air work in tunnelling, also referred to in some quarters as caisson work and diving, has all but disappeared in modern tunnelling, but new challenges have been thrown up by deeper tunnels and those of larger section. These are being taken up by sophisticated procedures to ensure the safety of those involved in necessary work. Maurice Jones reviews some leading practitioners and their tunnelling work and equipment. Additional material from Nicole Robinson

Soil conditioning for clays in EPBMs – part two
14 November, 2011
In the second part of this paper, commenced in the October 2011 issue of T&TI, the authors further explain the mechanisms in clayey soil and machinery interactions and the testing of means of reducing adhesion

Modern compressed air and gas work
10 November, 2011
Work in compressed air has its origins in the early-to-mid 19th century. It is relatively uncommon these days and consequently few tunnellers have had experience of current practice. Donald Lamont of Hyperbaric & Tunnel Safety reviews its development, current practice and its context in tunneling

Holding it together: the birth and life of a fibre
19 October, 2011
As a more light-hearted look at the subject of steel fibre reinforcement of precast concrete, but with serious content, this article is an insight into the sometimes dynamic life of a fibre from manufacture to being held in position in the structural lining of a tunnel. Maurice Jones followed its progress

Mitigation and alternatives: making hand mining better
26 September, 2011
A current trend in tunnelling, as in many other industries, is against manual labour, but in many situations hand mining seems the logical first choice until one considers the hazards involved that are arguably greater then those associated with large-section tunnelling. Maurice Jones checks on the current status of the activity, mitigation to improve hand mining, and the alternatives offered by some equipment manufacturers.

HAVS in the law
23 September, 2011
Whatever the arguments and attitudes about applicability, the legislative framework intended to protect the health of the tunnelling workforce, and those encountering vibration in many other industries is inescapable. The editorial team checked on current legislation in some main tunnelling locations

The Eupalinos’ Tunnel on the Island of Samos
16 September, 2011
A dictator’s legacy, brutal working conditions and ancient instrumentation are examined in this report on what was both the longest tunnel ever built at the time and the first to be driven from both ends. Dr Myles O’Reilly, chairman of the T&TI Editorial Advisory Board, gives an insight into the techniques, thinking and capabilities of ancient tunnellers

Keeping London Underground dry
25 July, 2011
In the complex and sometimes ancient world of the London Underground, or ‘Tube’ as it is known colloquially, maintenance and refurbishment are major priorities within a capacity improvements programme. Water control is only one, but an important, part of this. Maurice Jones spoke to Dr Keith Bowers, Engineer in charge of London Underground tunnels for Transport for London

Speeding freight under Antwerp docks
21 July, 2011
In the highest value current construction project in Belgium an international public-private-partnership (PPP) consortium is building an important rail link to the west of Antwerp to handle the booming freight traffic to and from the port. The work includes tunnelling under waterways in tricky, soft-ground conditions and utilising an existing, but unused tunnel. Maurice Jones reports from Antwerp
