Innovation for sewer systems New device facilitates repair work

While repair work in inaccessible sewers is carried out by remote-controlled robot systems, the repairs in accessible sewers are usually carried out manually inside the sewer. Workers have to painstakingly coat fibreglass mats with reaction resin inside the sewer and to manually build it up layer by layer in the inlet of the pipes that need to be repaired – not really the nicest workplace as the odour of the sewer and the reaction resin make it a difficult task. In order to shorten the time spent in the sewer, an engineering firm has developed a new type of pressing device using Trovidur®. It makes it possible to have much of the work take place outside the sewer system. Trovidur® supports the pressing device The workers fit the pressing device with the fibreglass mats and the reaction resin already inside the service vehicle. Inside the sewer, they simply place the device at the respective inlet and, by applying pressure, press the fibreglass mat to the area that needs to be repaired. Trovidur® facilitates this pressing process at several points. A base ring with a thickness of 8 mm distributes the contact pressure very effectively during the pressing. Another 3 mm thick ring on the fitting adapts perfectly to the shape of the inlet, compensates for any unevenness and at the same time is stiff enough to hold the fibreglass mats impregnated with the reaction resin in position until they harden.
