Herrenknecht TBM constructs large road tunnel in Switzerland
The shell of the Belchen rehabilitation tunnel has been completed. Tunnelling ended successfully in Eptingen in the Swiss canton of Basel-Country on June 21, 2017, three months ahead of schedule. The tunnel boring machine (TBM) (diameter 13.91 meters) designed and manufactured specifically for this purpose at the Herrenknecht plant in Schwanau, Germany, excavated 3.2 kilometers of tunnel through complex geology in only 16 months. The new structure is the prerequisite for rapid and economic rehabilitation of the two existing parallel road tunnel tubes.

The steady renewal of the “Auer Ring” long-distance drinking water system in the Western Ore Mountains in Saxony – an interim report
Simply for geological and topographical reasons alone, the renewal of a drinking water transport pipeline in the densely wooded region of the Western Ore Mountains is no straightforward undertaking. Thanks to modern piping systems with their highly developed structural design methods, joint technologies and corrosion protection techniques, projects of this kind can be handled without problem. In the case illustrated here, the planning engineers were confronted with a fairly unusual additional challenge in the form of the soft, unbuffered water in the reservoir which, in conjunction with the cement mortar lining of the pipe, can be subject to an inadmissible increase in its pH value in stagnation phases. By using a proven method, endorsed in the DVGW regulations, of applying carbon dioxide gas under pressure in individual sections of the pipeline before acceptance and commissioning it was possible to ensure that the drinking water in the “Auer Ring” always meets the directives of drinking water legislation.

Rehabilitation of large profiles lacking long-term stability
Many large interceptor sewers, predominantly installed under public roads, have been in use for over 100 years. They are made of brickwork or compressed concrete and often show serious damage, so that it would seem that long-term stability can no longer be guaranteed. As an alternative to replacing large profiles, various renovation procedures offer significant advantages with respect to investment costs, environmental protection and urban pollution. Depending on the procedure, it may well be possible to extend the service life, in order to match that of a replacement. However, beforehand, an in-depth study of the current stability and residual load capacity of the existing sewer is required, along with needs-based selection and dimensioning of the rehabilitation procedure. The new standard DWA-A 143-2 serves as a good basis for the necessary static calculations.

Kanzingbach power station (Tyrol) with a high boost in output – increased security provided by “leak-before-break” fracture mechanics design of turbine pipes
The use of ductile iron pipe systems for penstock pipelines is constantly increasing with the promotion of renewable energy sources. In this area of application the mechanical and technological requirements placed on pipe materials as well as the need for security are considerably higher than for pipes used for the distribution of drinking water. Therefore it is imperative that material modifications are developed to meet these increased demands. This report describes the safety concept (the “leak-before-break criterion), the technical material modifications and investigations necessary for practical implementation which will result in better utilisation of ductile cast iron as a material in high-pressure applications and the particular requirements for both crew and piping systems when laying turbine pipelines in alpine environments. All in all a basket of technical goodies!

Cleaning waste water effectively
Water is vital – therefore, waste water has to be cleaned as efficiently as possible. Ceramic membranes make this possible. Researchers from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Hermsdorf, Germany were able to significantly reduce the separation limits of these membranes and to reliably filter off dissolved organic molecules with a molar mass of only 200 Dalton. Even industrial sewage water can thus be cleaned efficiently.
