構造。 A rubber ring is used to close the gap between the side hole of the manhole and the end of the pipe inserted into the side hole, with a hollow part that extends outwardly and outwardly provided in the center of the rubber ring, and a fluid is poured into the hollow part. After filling, tightening bolts were inserted through the fluid-filled portion in the inner and outer directions at regular intervals, and the rubber ring was made to bulge out in the non-tightening direction in different sizes depending on the degree of tightening of each tightening bolt. A joint structure between a manhole and a pipe culvert.
