EARTHQUAKE-RESISTANT MANHOLE STRUCTURE AND EARTHQUAKE-RESISTANT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide an earthquake-resistant manhole structure constructing a connection part between the circumference wall of a manhole and a water service pipe into an earthquake-resistant structure. SOLUTION: In this earthquake-resistant manhole B, the water service pipe 4 is inserted into a tube body insertion hole 5 arranged in the manhole circumference wall 3a and connected movably. An earthquake-resistant member 13 constructed of an invert block 11 having a groove part 11a on the upper face and a displacement absorbing member 12 abutting to the end part of the invert block 11 is arranged in the inside bottom part of the earthquake-resistant manhole B. The displacement absorbing member 12 in the earthquake-resistant member 13 is brought into contact with the end face of the water service pipe 4 facing the invert block 11.
