METHOD OF SEALING MOUTH OF AN INLET PIPE, ENTERING FROM A SIDE A SEWER PIPE AND APPARATUS FOR MAKING THE SAME

摘要

The method for sealing the opening of a side conduit (3) which opens at the side into a main pipe (1) uses a connecting piece (4) with an expandable fibre fleece which can be pressed by an expansion body (15) into the side conduit (3). The connecting piece (4) is driven into the main pipe (1) on the expansion body (15) with a carriage (5). A television camera (9), driven therewith, is brought into position on the same axis with the opening of the side conduit (3) which is to be sealed. The connecting piece (4) is aligned radially and displaced towards the side conduit (3). Subsequently, the connecting piece (4) is brought into contact with the opening on the edge of the opening, superimposed on said opening, with the aid of a pressure plate (13), and is pressed into the side conduit (2).
