PROCESS AND DEVICE FOR RELINING SERVICE DRAINS JOINED TO INACCESSIBLE MAIN SEWAGE DRAINS

摘要

A process and device allow service drains (3b) that lead directly from a building or draining shaft to a main sewage drain (4) to be sealed by means of a relining process using inliners (1) made of self-curing sealing materials. In order to apply the disclosed process, a relining machine (6) is used bearing on its head (14) a cable guide (10) composed of a pulley holder (15) to which are secured a deflection pulley (5) and a safety pulley (16). The cable (7), to which the inliner is fixed, is threaded into the cable guide (10) of the relining machine (6) and the relining machine (6) is positioned in the main sewage drain (4) next to the outlet (2) of the service drains, so that when the cable (7) is stretched it does not touch the edge (9) of the service drain that faces the relining machine (6). When the cable (7) is drawn in, a stand (11) provided with a chock block (12) prevents the machine (6) from moving.
