The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common. The aftermath of the hurricane “Gudrun” has forced several power companies to re-evaluate their electric supply network, which has lead to more placements of power cables underground.</p><p>We have come to the conclusion that there are several factors that would affect the method of choice for cable excavations. Costumer demands, obstacles and the difference in ground conditions are vital factors behind the verdict for suitable production methods.</p> Power cable ground excavations for power cables placements of power cables Estlink production methods trenchless methods horizontal drilling Kraftkabel kraftkabelförläggning kabelförläggning produktionsmetoder Estlink schaktmetoder schaktfritt schaktfria metoder horisontell rördrivning Building manufacturing engineering Byggproduktionsteknik

The work is divided into several parts. The first part is a description of the preliminary research based on appointments with the operator of the sewer network. The second section describes the basic information on the assessment of the sewer network. In the third part, the evaluation of technical and operational conditions according to ČSN EN 13 508. This section was supplemented by creation of supportive software program in Microsoft Office Excel, which is based on the proposed TNV 756905. In the next part the environmental assessment was performed digging and trenchless technology and then selected a possibility representative to design of selected parts. The fifth and sixth section contains technical and economic evaluation designed technology. A final section deals with the choosing optimal rehabilitation technologies for the design of selected parts of the sewer network.
