KEEP YOUR PIPELINE PROJECT GOING

摘要

Anne Knour, Market Communication Manager, TRACTO-TECHNIK, Germany, discusses the latest trenchless technologies and HDD assist and rescue methods for pipeline installation. Trenchless technology is primarily leveraged for the installation of underground utilities, creating the least amount of surface disruption possible, saving time, costs, and resources. In particular, pipe ramming and horizontal directional drilling (HDD) are favourable methods for implementing even highly complex and challenging pipeline construction projects. But when something goes wrong at an HDD jobsite and rapid action is needed, a pipe rammer is also the means of choice applying so called assist and rescue methods. This article describes the options for trenchless pipeline installation and illustrates the different HDD assist methods, including a practical example.
