Remediation of drainage pipeline and testing of watertightness

U radu je predstavljena sanacija i ispitivanje vodonepropusnosti cjevovoda odvodnog sustava. Rad je koncipiran u nekoliko poglavlja. U uvodu je kratko opisana energetika kako grana strojarstva te predstavljen kolegij cjevovodi i tlačna oprema. U teorijskom djelu rada opisan je odvodni sustav te analiza pojave pukotina snimanjem cjevovoda pomoću CCTV video sustava. U praktičnom dijelu rada objašnjena je sanacija cjevovoda odvodnog sustava i ispitivanje vodonepropusnosti prema odreĎenoj normi. Svaki od postupaka ilustriran je fotografijom snimljenom radom na terenu odnosno animiranom fotografijom kao internom dokumentacijom tvrtke.The paper presents the rehabilitation and testing of waterproofing of the drainage system pipeline. The work has been conceived in several chapters. In the introduction, the energy is briefly described as a branch of mechanical engineering and represented by the Collegium pipelines and pressure equipment. In the theoretical part of the work is described drainage system and analysis of the appearance of cracks by recording of pipelines using CCTV video system. In the practical part of the work, the rehabilitation of the drainage system pipeline and the testing of waterproofing according to a certain standard is explained. Each of the procedures is illustrated with a photo taken on the ground or animated photography as an internal documentation of the company
