Chairman’s Welcome

The level of exposure and promotion that Trenchless Australasia is providing the Trenchless Technology industry is a wonderful boost for all those involved in the industry. The quality of our journal, and its ever growing distribution, means the very positive messages of the benefits of Trenchless Technology are being delivered to a wider and wider audience.

ASTT facilitates overseas involvement

TRENCHLESS ASIA 2006: huge opportunitites for business in China

TRENCHLESS ASIA 2006 will be held at the Shanghai Exhibition Centre on 7-9 March 2006. This is the second international trenchless exhibition and conference to be held in Shanghai and follows the highly successful first conference in 2004. This event is part of a worldwide series, with other events held in Singapore, Hong Kong, Cairo and Dubai.

Second enviroNZ Conference underway in New Zealand

Delegates consisting of water and wastes professionals, operators, trenchless technology contractors and consultants are gathering at the Aotea Centre, Auckland between 28 –30 September 2005 to learn about the latest developments and to see state-of-the-art technology in the Trenchless Technology and water sectors.

New Zealand Councillor’s Report

State of the Market Like always, I believe Trenchless Technology is still trying to gain acceptance and credibility as an alternative to conventional excavation and while we are making headway, there is still a long way to go.

The development of HDD in Australia

A conversation with Andy Lukas, Australian HDD pioneer HDD – horizontal directional drilling – was developed from oilfield drill control techniques. It set out to solve the problem of installing a pipeline beneath an obstacle where conventional trenching was difficult or impossible. By sending the pipeline below particular geographical features, there is no environmental risk or other effect.

Automatisation of HDD drill rigs: an history summary

Dr. Hans-Joachim Bayer, Kohlberg, Germany

During the 1990s, European manufacturers and affiliated research institutes paid particular attention to the automatisation of HDD. This article provides an overview of the fundamental and extensive European technology developments in HDD automatisation.

Vermeer holds HDD ‘drill school’ sessions

During August, Vermeer conducted a series of HDD ‘drill school’ sessions around Australia, during which attendees were addressed by a variety of Vermeer and industry professionals on issues affecting the HDD industry today.

Infrastructure Constructions completes major Telstra contract

Infrastructure Constructions recently secured a major Telstra project to relocate 7 km of Single Mode Optical Fibre and 3 km of copper cable around the Norwest Business Park across the intersection of Old Windsor Road and Norwest Boulevard. This project was a major challenge for Infrastructure Constructions due to the location, ground conditions (rock) and interaction required between all the current construction companies working in the area.

HDD expertise from BTB

BTB Australia has been involved in the directional drilling industry for many years now and brings a wealth of experience, innovation and expertise to any project requiring HDD installation of conduits or pipelines.

Central Asian HDD success for Stockton

Stockton Pipelines was recently involved in the construction of the 1,900 km Baku-Tbilisi-Ceyan (BTC) and South Caucus Pipeline (SCP) projects in Azerbaijan, successfully executing seven Horizontal Directional Drilled crossings on the Central Asian projects.

Drilline refurbishes collapsed sewer line in Perth

Drilline Pty Ltd is a Western Australian owned and operated company providing specialised services to the civil infrastructure and urban development industries.

Jacking success for Perry in Sydney

In the increasingly congested areas of our major cities local and State governments are planning and constructing pedestrian walkways and cycleways in ever increasing numbers. These accessways provide a challenge for builders as construction often requires many crossings of roads, railways and other immovable objects.

Tunnel Boring breakthrough for Robbins

The final tunnel boring machine (TBM) breakthrough of the Epping to Chatswood Rail Link in Sydney occurred in late July 2005 after another TBM broke through a month prior.

A new age dawns on pipeline inspection technology

As demand on infrastructure increases so too does the necessity for maintenance and the requirement for long term sustainability. Asset owners have been adopting preventative maintenance programs as the best and most economical means of accomplishing this for many years and few would disagree that an emphasis on systematic condition assessment is of paramount importance.

Watani polycrete pipe and MH systems

The Al Watani factory in Kuwait is a leading producer of polycrete products, manufactured to the DIN 54815-1 standard using state of the art technology. Patented technology and over 15 years of experience in polycrete see the traditional properties of concrete combining with the high level of corrosion and chemical resistance achieved from the latest polymer resins.

Successful water main installation for UEA

UEA recently completed a water trunk main installation at a new development site in the Sydney suburb of Rhodes for CLM Excavations on behalf of Sydney Water. The project required UEA to install 140 m of 560 mm polyethylene (PE 100 PN 16) under a railway line using Horizontal Directional Drilling.

Wagga City cuts costs not roots

Supervisor of sewer operations for the City of Wagga Wagga, Len Kennedy, is changing the way things are done. Len has initiated a targeted pro-active program of treating branch lines and short sections of mains with Vaporooter foaming sewer root inhibitor in problem areas in order to reduce sewer chokes and overflows which cause inconvenience to customers and result in the excessive cost of emergency response call outs.

Multipurpose units provide better service for spot repairs

A range of Trenchless Technologies for the rehabilitation of sewer and stormwater pipes is now available in Australia. Some of these techniques are capable of lining over 400 m of pipe in a single installation. But what happens when there are only one or two areas in a length of a pipeline that need repair? Sometimes it can be more cost effective to fix just these areas with a spot repair, especially if the spot repair uses Trenchless Technology.

Rodney Council pipe installation

Smythe Contractors successfully undertook their boldest project yet with the installation of a 710 mm diameter PE pipe, over a continuous length of 400 m up to 40m deep.

Pipes Wagga Wagga

Pipes Wagga Wagga 2005 will be held at the Charles Sturt University Convention Centre in Wagga Wagga from October 17-21 and will provide engineers and practitioners with practical skills and tools to assist in dealing with pipes.

Double circular liner for oviform sewer

While a large and well accepted range of liners are available for structural rehabilitation of deteriorated circular sewers, the same solutions cannot be so readily applied to oviform (egg-shaped) sewers.
