Bauteilversuche Oberesslingen – Teil 1: Konzeption des Auftraggebers.

Component tests Oberesslingen – part 1 – conception of the client As part of the Federal Waterways Engineering and Research Institute's research and development project Repair under Operation (IuB), component tests are being carried out together with the Heidelberg Waterways Engineering and Construction Office, the Institute for Technology and Management in Construction Operations at the Karlsruhe Institute of Technology and the Directorate‐General for Waterways and Shipping in order to identify suitable methods for the basic repair of a lock chamber under time‐ and space‐restricted boundary conditions with regard to working times and space conditions. The component tests are taking place at the Neckar lock Oberesslingen in the right‐hand chamber, which was previously used as a savings chamber for the left‐hand chamber. The scope ranges from partial demolition of the chamber wall for reprofiling by means of a facing concrete and partial drainage to a solution with a framework that could be used to carry out gate replacements within a short time in the future. The comprehensive design of the component tests includes the mandatory and technical requirements that must be considered. These include both generally valid requirements for the feasibility of the tested procedures on other locks as well as specific requirements that are decisive for the implementation in Oberesslingen. Characterizing for the component tests is the possible use of innovative processes and approaches and the resulting deviations from the regulations. [ABSTRACT FROM AUTHOR]
