Possibilities of lowering of PM emissions to ambient air using trenchless technology instead of open cut when building burried pipelines

摘要

When constructing underground infrastructure, either the open cut method or the trenchless one, we are faced with fugitive emissions to ambient air. First section provides overview of particles and how they are introduced into the environment according to the selected technology. In following section base for the fugitive OM emisiionsudcalculation is set up, based on on-road and off-road machinery, as well as the manipulation of the ditch spoil, the pipe bedding and the overlay. The core of the thesis is calculation of fugitive PM emissions on construction site, depending on cover and selected technology and analysis of results.ud
