<p><P>PROBLEM TO BE SOLVED: To provide a differential settlement countermeasure piping structure which can avoid a crack, damage and come-up of a pipe line embedded in the ground and the inclination and breakage of a fluid catch basin, and can solve a problem of the leakage of liquid. <P>SOLUTION: To a pipe end 2a of a service pipe 2 piped from a building into the ground, a pipe line connection part 4 is connected which is turnable relative to the pipe end 2a. A flow-in side connection part 7d of the fluid catch basin 7 having the flow-in side connection part 7d and a flow-out side connection part 7f is formed in a turnable connection structure. Between the pipe line connection part 4 and the flow-in side connection part 7d, the pipe line 3 is connected which has a first bent part 8 bent in a horizontal plane including the axial direction of the service pipe 2, a flexible part 5 flexible in the longitudinal direction, and a second bent part 6 bent in the opposite direction with respect to the first bent part 8. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
