New process requires less space and saves costs
The near-surface installation of pipelines usually causes massive disturbance to the environment. It can create corridors up to 50 metres wide. The BINE Projektinfo brochure “Swift construction of pipelines” (04/2014) presents a method that requires less than one fifth of the usual width. The steel or concrete pipes can be used for heating networks and can connect more distant customers faster and in a more environmentally friendly manner.
The operator vehicle controls and monitors the system. The excavator unit loosens the ground and conveys it directly to the surface.

Until now, corridors often more than 50 metres in width have been created along the entire length of pipeline routes for digging trenches, temporarily storing soil, as well as transporting and storing materials. Despite reclamation work, the consequences for the environment are still visible even after years. The Pipe Express method eliminates the need for complicated trench excavation work. Since this reduces the effort required for renaturisation measures, costs can be saved.
With the Pipe Express method, a tunnel boring machine drills through the ground. An excavation unit loosens the soil and transfers it to the surface. An anchored thrust element (pipe thruster) provides the necessary jacking. It simultaneously pushes the pipeline into the horizontally generated bore hole. The driver in the operator vehicle monitors and controls the system along the pipeline. Pipelines laid in this manner can be used for transferring district heating, communications and data cables, power cables, oil, gas and water. In future, the Pipe Express method could play a greater role in integrating geothermal power plants into the heat supply for urban settlements.
The Pipe Express process was developed by Herrenknecht AG and has been sponsored with funding from the German Federal Ministry for the Environment.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

Scientists at the Helmholtz Zentrum München have developed a new mass spectrometry imaging method which, for the first time, makes it possible to analyze hundreds of metabolites in fixed tissue samples. Their findings, published in the journal Nature Protocols, explain the new access to metabolic information, which will offer previously unexploited potential for tissue-based research and molecular diagnostics.
In biomedical research, working with tissue samples is indispensable because it permits insights into the biological reality of patients, for example, in...
