Latest developments for the trenchless construction of pipelines

HDD Technology is established as standard technology for trenchless laying of pipelines. Projects, which would have been technical highlights some years ago, today can be seen as standard. But the increase of demands on projects in terms of bigger diameters, achievable length and geological conditions takes the HDD technology more and more to its absolute limits. Other available technologies such as microtunnelling are in use but have not yet reached the same importance for pipeline construction as HDD, although this method itself has already extended the possibilities for pipeline projects. New technological developments combine the HDD method with those qf microtunnelling. Push-Pull Technology, Easy-Pipe (R) and Direct Pipe (R) of more possibilities for realization of ambitious pipeline projects.
