nr 11

70--74

Podano dwie propozycje planowania inspekcji CCTV przewodów kanalizacyjnych dotychczas jeszcze nie zbadanych oraz trzy propozycje dotyczące inspekcji CCTV przewodów kanalizacyjnych już wcześniej zbadanych. Sformułowano zalecenia dotyczące wykonywania dodatkowych badań przewodów. Podano także dwie propozycje ustalania kolejności typowania przewodów kanalizacyjnych do odnowy oraz propozycję metody ABCDE dotyczącej tego zagadnienia.

Two proposals for planning CCTV inspections of sewage pipelines not yet investigated have been provided, and three proposals for CCTV inspections of sewage pipelines which have been earlier investigated. Recommendations for additional surveys of sewers have been formulated. There are also two proposals for determining the ordering of sewers for renewal and the ABCDE method for this issue.

Analysis of defects with a proposal of the method of establishing structural failure probability categories for concrete sewers

The objective of this study was to identify and classify the type, size and frequency of structural defects occurring in concrete storm water, sanitary and combined sewers that have been in service for a long time. Another aim was to develop a method of classification of those sewers into five categories of failure probability. The paper presents results of non-destructive CCTV surveys of concrete sewers, which were conducted in different Polish cities. It also describes the causes of the defects that are related or unrelated to the type of flowing sewage. In the method proposed in the study, the matrix PS was developed. Elements of this matrix were determined. They contain lower boundary values that define the size of the analyzed defects for five categories of sewer failure probability. The proposed method allows classifying every analyzed sewer into one of five categories of sewer failure probability. The method can be used as a tool in sewer rehabilitation planning. The key conclusions highlight the causes of sewer failures, the scale of hazards and the benefits resulting from the application of the proposed method to prioritize analyzed sewers into one of five categories of failure probability.
