A Robbins Mixed Ground Cutterhead has been used in a record breaking distance for a small boring unit.
Trenchless International takes a look at some of the exciting tunnelling projects around the world.
Essential infrastructure is being rapidly expanded across China. One of the largest projects, the second West – East Gas Transmission Pipeline, is using Trenchless Technology to protect sensitive environments.Jamie Dorey
The application of Trenchless Technology is common in many important resource sectors including gas and oil. Here we discover how horizontal directional drilling is being used to access coal seam gas.
Environmental considerations for pipeline construction with horizontal directional drilling are discussed in the latest edition of The Journal of Pipeline Engineering (JPE). Here, Editor-in-Chief John Tiratsoo outlines an article discussing horizontal directional drilling construction methods.
Fort McMurray is the major urban centre within the Regional Municipality of Wood Buffalo, located in northeast Alberta, Canada, the town is situated just south of a major oilsands development. To service the expansive urban growth in the area, the municipality has invested in major infrastructure upgrades, including twin sanitary sewer forcemain crossing of the Athabasca River.
InfraTrain New Zealand has launched an extensively revised qualification for horizontal directional drilling (HDD), which has been developed in partnership with the trenchless industry.Wim Elzink, Product Manager Wavin Overseas B.V.
Pressure pipelines are often in urgent need of rehabilitation. Here Wim Elzink looks at renovation options by lining with plastics pipes – in particular with polyethylene pipes – using a variety of techniques.
The rehabilitation of 146 metres of oval-profile DN 600/900 as part of the comprehensive restoration of Schloss Hubertusburg, a cultural heritage site in Wermsdorf in the German state of Saxony, has been achieved with light cured CIPP.Paul Heenan, KA-TE PMO AG
The evolution in the repair of underground infrastructure such as water and wastewater pipes has resulted in the development of a highly competitive market in relining options. Here Paul Heenan from KA-TE PMO AG reflects on the importance of independent testing in the development and use of new products.Dr-Ing R Stein and Dipl-Ing H Cakmak, S & P Consult Bochum GmbH
The maintenance of road gully systems in Germany is often a neglected component of the wastewater network. This is part one of the analysis of a survey conducted to assess the cleaning, inspection and rehabilitation of road gullies in Germany.Norman Joyal, Associate, Jacobs Associates
The trenchless industry is technologically advanced and consistently innovative. Cutter soil mixing technology is one such example that has been developed to construct shafts for microtunnelling projects. Norman Joyal reports here about one of the first projects in the United States using this technology to build microtunnelling shafts.Tomo Morita, Hideki Shimada, Takashi Sasaoka, Kikuo Matsui, Fumihiko Matsumoto and Eiji Sakai
Circular pipes have been used for over a century to construct infrastructure in urban areas. Rectangular pipes, on the other hand, and in particular pipes installed by pipe jacking, are a fairly recent development. In this article the authors describe the development and assessment of a rectangular pipe jacking system.
GDK is currently completing construction on Petrobras’ GASTAU Project, which includes a 28 inch diameter, 97 kilometre natural gas pipeline extension running from the north coast of Brazil to 760 metre elevated plains between the cities of São Paulo and Rio de Janeiro, involving numerous river and road crossings.
A water authority in Campinas, Brazil, has purchased trenchless machinery to replace and enlarge existing drinking water pipelines.
Vacuum systems are becoming a popular choice for the drainage of municipal sewage. SEKISUI SPR Europe GmbH has an innovative technology that combines all the advantages of vacuum systems and offers enormous potential for the global wastewater market.
The inaugural International Conference on Pipelines and Trenchless Technology (ICPTT), held in Shanghai, China from 19–21 October 2009, provided a forum for 80 presentations addressing the latest projects and technology for the water, sewer, gas and oil industries.
Due to the popularity of Trenchless Middle East Abu Dhabi 2010 the organisers have expanded the exhibition and opened up the East wing of the Great Tunb Hall to accommodate more exhibitors. Record numbers for both the conference and the exhibition are expected.
The 4th International Conference and Exhibition No-Dig Poland 2010 will be held 27–29 April 2010 in Kielce at the Congress Hotel – Business Centre.
The 16th annual Underground Construction Technology International Conference and Exhibition 2010 will be held in Tampa, Florida, US from 19 – 21 January 2010.
No-Dig Moscow 2010 is set to be a key event in the trenchless calendar for this year.
Trent H. Ralston, past chairman of the NASTT, passed away on 9 November 2009 in Nashua New Hampshire, US at the St Joseph Hospital.
