发明名称 VERFAHREN UND EINRICHTUNG ZUM SANIEREN VON ABWASSERKANAELEN
摘要 The invention relates to a process and a device for cleaning drains (1). To this end, thermoplastic pipes (3) are introduced into a drain (1). A deformable body (7) is then positioned in the drain so lined, in front of the outlet of a domestic connection (2), by means of a carriage (6), the outlet first being covered by the wall of the plastic pipe (3). The deformable body (7) is then pressed from the inside of the drain (1) against the wall of the plastic pipe (3). The deformable body (7) is heated and heats the plastic pipe (3) causing it to melt. The deformable body (7) is then inserted into the domestic connection (2) where it forms a connection piece (11) from the region of the plastic pipe (3) covering the outlet of the domestic connection. The connection piece (11) is cut around its edge. The deformable body (7) is then retracted to the carriage (6).
