Fehlermöglichkeiten beim Herstellungsprozess von Tunnelinnenschalen

Abstract: Der vorliegende Beitrag befasst sich mit moglichen Fehlern, die wahrend des Herstellungsprozesses von Tunnelinnenschalen entstehen konnen. Dabei werden die einzelnen Herstellungsphasen, Arbeitsablaufe sowie unterschiedliche Rahmenbedingungen in Bezug auf mogliche Schaden und Mangel an der Tunnelinnenschale einer Analyse und Bewertung unterzogen. Dies beginnt mit den vorbereitenden Masnahmen zur Verlegung der Abdichtung und dem Einbau der Abdichtung, geht uber den Bewehrungseinbau, die Ausbildung des Schalwagens bis zum Betonieren der Schale sowie deren Nachbehandlung und die Beseitigung entstandener Fehlstellen. Es erfolgt anschliesend eine Zuordnung in unterschiedliche Verantwortungsbereiche bzw. Ursachen. Anhand dieser Untersuchungen lassen sich Empfehlungen zur Reduzierung und Vermeidung von Fehlerquellen sowie zur Qualitatssteigerung von Tunnelinnenschalen ableiten. Source of Errors during the Manufacturing Process of Internal Tunnel Shells This present contribution is concerned with possible mistakes which can develop during the production process of internal tunnel shells. The individual manufacture phases, operational sequences as well as the different basic conditions regarding possible damage and an evaluation and analysis of the internal tunnel shells deficiencies are submitted. This begins with the preparatory measures for the laying of the insulation and the mounting of the insulation, the reinforcement mounting, the drilling of the formwork car, and the concreting of the sealing and the installation of the sealing, the armouring installation. An assignment occurs afterwards of different areas of responsibility and causes. On the basis of these investigations, recommendations are made regarding the reduction and avoidance of sources of error as well as the quality increase for internal tunnel shells.

A Study on the Oxidative Gradient of Aged Traditional Triterpenoid Resins Using “Optimum” Photoablation Parameters

Abstract: KrF excimer laser ablation of two artificially aged triterpenoid films was studied. Ablation rate variations across film thicknesses implied compositional change with depth. Deviations between calculated and measured depths-steps at deeper ablated layers verified previously determined gradients. The findings were confirmed with DTMS, which demonstrated that excimer laser ablation with optimum fluences does not induce oxidation.

Method for separation of carbon dioxide from gaseous mixture and/or flow of gas for use in e.g. oil refinery, involves contacting gaseous mixture and/or gas stream with mixture containing amidine, water and aprotic solvent

Abstract: The method involves contacting gaseous mixture and/or gas stream with a mixture containing an amidine, water and aprotic solvent e.g. dialkyl ether, containing an ether and/or ester group such that a partially insoluble amidine-carbon-dioxide adduct or reaction product is provided as outcome. The amidine and the water are provided in a specific ratio before contacting carbon-dioxide, and the reaction product is separated.
