ANTISEISMIC STRUCTURE OF PIPE LINE
To provide an antiseismic structure capable of improving antiseismic performance for a pipe line.SOLUTION: An antiseismic structure 10 of a pipe line 1 connected to a manhole is provided with: a concave guiding groove 20 formed along a circumferential direction of an inner peripheral surface of the pipe line 1, at least a part of which in the circumferential direction has discontinuity; a cut-off body 31 having flexibility and covering the guiding groove 20 from the inside of the pipe line 1; and an expansion part 32 expanding the cut-off body 31 from the inside of the pipe line 1 to press it on the inner peripheral surface of the pipe line 1.SELECTED DRAWING: Figure 2
【課題】管路における耐震性を向上させることが可能な耐震構造を提供する。【解決手段】マンホールに接続された管路1の耐震構造10であって、管路1の内周面において周方向に沿って形成されると共に、周方向における少なくとも一部が不連続となるように形成された凹状の誘導溝20と、可撓性を有し、前記誘導溝20を前記管路1の内側から覆う止水体31と、前記止水体31を前記管路1の内側から拡張させて、前記管路1の内周面に押し付ける拡張部32と、を具備した。【選択図】図2
