Abstract (en)
[origin: WO9712096A1] In connection with applying new road-surface materials it is usually necessary to carry out a corresponding height adjustment of frames (18) for manholes present in the road, this traditionally being done by prying-up the frame, placing one or a number of spacer rings and reinstalling the frame. By the present invention it is realized that it is possible advantageously to limit this operation to carrying out a simple raising of the frame to a level a little above its new installment level, after which the spacer ring or rings in segment-divided form (2) can be installed by pushing them outwardly from inside the throat of the well, after which the frame is lowered. At their ends, the ring segments (2) are shaped with complementary protruding narrow parts (8, 10) that close the butt joints in question, thus preventing loose material from the surroundings from falling into the mahole or well.
