dr in偶. Tomasz Abel, dr in偶. Bogdan Przyby艂a, Beata Nienartowicz

The goal of the workshops is to discuss the basic rules of designing pipeline rehabilitation liners in reference to the DWA-A 143-2 guideline and the audit work issues.
Discussed topics will include:
• assessment of the existing pipeline,
• rehabilitaion methods in reference with the assessement outcome,
• input data for the design and the load imposed on the liner,
• imperfection problem, technical state III and IIIa,
• determination of the internal forces and dimensioning for operation and mounting,
• calculation scheme
• quality of work assessment

During the lecture there will be discussed rules of liners dimensioning in reference to the DWA-A 143-2 guideline
