<p>PROBLEM TO BE SOLVED: To provide a connection structure of an underground buried skeleton and a pipe body capable of easily performing the connection work of the pipe body, following ground fluctuation after the construction, and allowing the use of an existing collar for connecting pipes because a large degree of tolerance of an angle for connecting the underground buried skeleton and the pipe body can be taken. SOLUTION: In this connection structure of the underground buried skeleton and the pipe body constituted such that is consists of a pipe end connection 11 formed on a manhole 10, the pipe body 12 abutted and connected to the pipe end connection 11, and the collar 13 for connecting the pipe end connection 11 with the pipe body 12 and the collar 13 has a collar main body 14, a rubber ring 15 on the pipe end connection side in contact with an outer peripheral face of the pipe end connection 11, and a rubber ring 16 on the pipe element side in contact with an outer peripheral face of the pipe body 12, a wall thickness of the pipe end connection 11 is formed to be larger than a wall thickness of the pipe body 12 so that an interval t2 between the outer peripheral face of the pipe body 12 and an inner peripheral face of the collar 14 is formed to be larger than an interval t3 between the outer peripheral face of the pipe end connection 11 and the inner peripheral face of the collar 14.</p> |
