Avaliação de poços de visita em polietileno pelo método não destrutivo de emissão acústica

Abstract

Manhole (PV) is a structure of sewage collecting networks where interconnection of sewage flows. Currently most PVs in use is made of precast concrete rings; reinforced concrete and masonry (with ceramic bricks or concrete blocks). Due to its material composition is easily subject to degradation, to suffer wear end up releasing the sand, causing various problems in treatment and in the treatment of sewage and public disorders caused by their failure. To resolve these problems, improve the quality and conditions of sewage treatment, implement business well produced of polyethylene, polymer material with significant features for this purpose, as for example, his inert character, weight, resistance and service life. To ensure that the product is in perfect condition for your installation is to check their structural integrity, that will be proven through nondestructive testing of acoustic emission.
