Considerations on Topographic Parameters of Rehabilitation Sewer Collectors

Sewerage collectors into operation a high degree of wear, which increases the flow section degradation. Decay most important processes occurring in the foundation plate collectors by processes of erosion or clogging. Rehabilitation sewerage collectors are distinguished by the geometric shape and dimensions of the cross section. Rehabilitation technology can alter the shape of the flow section and longitudinal slope default collector. To determine the functional parameters must be known collector slope created through rehabilitation. Determining slope is achieved by surveying. Surveying is customized according to the size of the collector (collectors visited, collecting non-visitable). To visitable sewer collectors can take measurements inside correlated with those outside the homes of visit. The non-visitable sewers can take measurements on the outside, inside homes to visit.
