Abstract

The bachelor thesis focuses on underground utility networks made with the microtuneling method. This method is used for water pipes, gas lines or even for cover of data wires etc. The opening chapter describes particular types of utility networks from the view of their parameters, construction materials, pipe connections and the waterresistent exams made on accomplished constructions. The main part of thesis shows very detailed description of particular methods of undirected microtunelling (used especially in short distances without the direction change possibility) and directed microtunelling (with a possibility of direction change during tunelling and also tunelling id difficult conditions). An attention is also paid to geological methods, geophysical and geotechnical survey of tracks of utility pipes and possible predictable negative influence caused during microtuneling. The final chapter ilustrates microtuneling on several construction cases.
