Study of rehabilitation of selected part of sewer network
Dvořák, Pavel ; Helcelet, Marek (referee) ; Raclavský, Jaroslav (advisor)
The topic of this thesis is to create a study of the rehabilitation of the sewer network. The sewer system under assessment is located in city Znojmo, specifically Znojmo – city. In this case, rehabilitation is proposed in order to improve the functional operational properties of the sewer network and extend its service life. The work was divided into two basic parts, namely the Accompanying and Summary Technical Report. Three variants of solution were proposed. The first two variants are made as trenchless using a sanitation sleeve in the first one and a short sanitation sleeve in combination with a sanitation sleeve in the second. The third variant is made as an open excavation recovery. A description of the rehabilitation technology was carried out and the facts that each individual Option or what the three Option would bring up were defined. These three variants of the solution are assessed in terms of economic, technical and environmental impact.
