In this thesis, we presented various technologies of built-in provided regular lines (new construction) at converging with the existing infrastructure. We presented the classical
technology of execution of crosses as well as technology of execution of trenchless crossings, so-called "Trenchless technologies." We focused on the technology, which are available and used in Slovenia, in implementation of regular lines. In addition, we also presented the latest technology DIRECT PIPE®.
In the practical part of the thesis we have made the project design of crucifixion primary conveyor pipeline for drinking water supply with a watercourse I. order. The design was made for the example of crossing with classic construction technology and technology implementation with microtunneling.
In the end we compared both project design of crossing of the primary conveyor pipeline for drinking water supply with a watercourse I. order. We compared the following elements: the complexity of implementation depending on the geological conditions, speed of implementation, cost, complexity of implementation depending on the availability of technological equipment, environmental impact and risk of disruption to work.
