Impacts of rehabilitation of sewer network on sewer hydraulics
Petrová, Diana ; Prax, Petr (referee) ; Raclavský, Jaroslav (advisor)
This diploma thesis focuses on the assessment of the technical condition of selected parts (2 branches) of the sewer network in Znojmo. First, an assessment and classification of the occurring defects was carried out based on the supplied camera recordings according to the coding system of the ČSN EN 13 508-2+A1 standard. Then, each section was classified according to its faultiness and the resulting technical condition into individual categories according to the methodology of TNV 75 6905 (draft) and remediation was proposed. The remediation in the first part A concerned sections falling into categories 2 and 3, where remediation was proposed by lining that hardens in place using a UV emitter. For the second part of the network (B), lining cured by UV radiation was also proposed for sections falling into category 2, and for sections in category 4, a complete replacement of the existing pipes with new ones was proposed due to their destruction and static insufficiency. An economic evaluation was prepared for such a remedition proposal. In the next part, an assessment was made to determine whether the proposed remediton measures do not have an adverse impact on the overall hydraulics of the network. This assessment was carried out in the SWMM program, from which it was found that the remediation does not have such a significant and drastic impact on the hydraulics of the network and its application (lining and replacement of pipes) should have almost no effect. This work includes individual appendices - Evaluation of the camera survey of selected sections of the sewer network according to ČSN EN 13 508-2+A1, Evaluation of the technical condition of selected sections according to TNV 75 6905, Situation evaluation of the technical condition of the sewer network - part A, Situation evaluation of the technical condition of the sewer network part B, Calculation of flow rates depending on the filling height for the original state before and after relief and CD with a camera survey of selected sections of the network.
