Abstract

PURPOSE: To prevent an external load from acting on a manhole drum part as a compressing force in the axial direction, and to permit even a plastic pipe having a relatively thin thickness to be used as the manhole drum material.
CONSTITUTION: A drum part 1 is divided into a upper part 1a and a lower part 1b, and the divided drum parts 1a and 1b are slidably (2) coupled together by the use of a rubber ring or grease etc. Since the adoption of the manhole constituted in such a manner as described above can prevent a compressing force in the axial direction, even a plastic pipe having a relatively thin thickness can be used.
