NEW LIGHT AT THE END OF THE MICROTUNNEL

In the first part of this article, Department of Transport proposals to charge contractors whose activities cause serious delays to traffic in the form of a lane rental charge, are discussed. This policy, if adopted, would lead to a greater adoption of trenchless technology techniques, which are less disruptive to road users. The proposed legislation is targeted at the small number of expensive projects, estimated at 5 per cent of total utility works, which account for 40 million in delays to road users. In the second part of the article, the use of microtunnelling equipment on a sewerage improvement scheme at wincham near northwich, cheshire, is described. 150 metres of 600 mm diameter concrete pipe was installed in two sections, after thorough site investigation had been carried out. The project involved passing 72 metres of pipe under a local canal utilizing a soltau rvs 250a machine with laser monitoring. In this instance trenchless technology offered clear benefits over conventional working because costs associated with canal closure were not incurred.
