This October I was fortunate enough to attend No Dig Madrid where I tapped in to the rich seam of ingenuity and practicality that characterises the trenchless industry. I have so many ideas for articles that I am not quite sure where to start, from developments in sensors and locators; repair robots and pipe liners; pipe materials and fi lter systems to faster HDD rigs and clever innovations that combine tunnelling with trenching.
From the UK where many trenchless methods were born, the history of no dig techniques dates back decades, so it is exciting to hear of well established methods being embraced in new markets.
The UK’s House of Lords committee on economic affairs has been hearing evidence on the potential impact on the exploitation of the country’s substantial shale gas resource. From the evidence given it is clear that there is a lot of work to be done to determine the true impacts of hydraulic fracturing.
The topics covered in this month’s issue of Underground Utilities have more in common than may be obvious at a first glance.
When the first issue of Underground Utilities was launched in February 2012 it contained a host of features that illustrated the diversity of construction methods present in the utilities sector. From clever adaptation of German plows to lay HDPE gas lines in Australia, to the pioneering use of guided auger boring on 1200mm diameter pipelines in the north of England, it was clear that here was an industry rich in technical innovation.
