2. Description of the Related Art Conventionally, a pipe joint structure of a manhole for connecting a drain pipe or a sewer pipe made of synthetic resin or the like to a manhole has conventionally been provided with a socket for joining with a pipe at one end, and at the other end. Insert a short pipe with sand that has been sanded on the outer surface to improve adhesion with cement mortar into a pipe joining hole that opens on the side wall of the manhole, and connect the pipe joining hole with the short pipe with sand. A cement mortar is filled in the gap to fix and stop water, and a saddle-shaped joint J as shown in FIG. 2 in which a flange b is integrally attached to a short pipe a with sand similar to the above. After the sanded end of the short pipe b is inserted into the pipe joining hole with the flange a of the joint J applied to the outer wall surface of the manhole, the cement mortar is packed and fixed in the same manner as described above. Epoxy or the like that mixes a main agent and a curing agent around part a Those to fix and water stop are performed by thickly applying a special bonding agent.
