The calculation module A 127 for IngSoft EasyPipe follows the worksheet ATV-DVWK-A 127, 3rd edition (2000 edition). In addition, we take into account the "state of the art" such as the LM1 road traffic load model, concrete grades such as C25/30 (instead of B25) and material parameters according to DWA-A 127-1.
We treat other standards such as AWWA M45 or SIA190:2017 analogously. Especially for newcomers to the pipeline industry, we recommend the basics of installation in trenches, because other installation methods(jacking/HDD and rehabilitation/liners, as well as manholes) are partly derived from the concepts of ATV-DVWK-A 127. For new installation in trenches, usually only the circumferential direction of the pipes is considered.
