Swift construction of pipelines. Method developed for the environmentally friendly installation of pipelines longer than one kilometre in length.
The laying of pipes, for example for heating networks, has previously been a labour intensive and time consuming occupation. With the newly developed “Pipe Express” method, a special tunnel boring machine drills through the ground at speeds of up to 1.2 metres per minute and conveys the soil directly to the surface instead of displacing it sideways. At the same time, the steel or concrete pipe is inserted into the horizontal borehole. In comparison with the open cut method, the process requires less than a fifth of the normal trench width and can also be used without lowering the groundwater level.
