摘要

Method for adjusting the height of the manhole cover of a manhole which has a manhole wall and a circumferential edge profile arranged on it, in which the manhole cover is arranged, the edge profile having a horizontal web and an outer edge web protruding upwards at a substantially right angle, the upper edge of which is essentially runs flush with the top of the manhole cover, recesses (5) being formed in the horizontal web (3), screw nuts (12) being arranged in a rotationally fixed manner under the recesses (5), screws (7, 8) from above the horizontal web (3) through the screw nuts (12) so that their lower ends rest on the top of the shaft wall (1), whereby the screws (7,8) are screwed in until the edge profile (2) reaches the desired height , characterized in that then lateral impact forces are exerted on the screws (7,8), whereby the screws (7,8) tight o Break off above the screw nuts (12).
