PIPE MOVEMENT PREVENTION DEVICE AND FIXING METHOD OF FLUID PIPING SYSTEM
PROBLEM TO BE SOLVED: To rationally form a pipe movement prevention device which achieves reduction of a construction period and construction costs while preventing pipe movement caused by uneven force during renewal of a fluid piping system.SOLUTION: A pipe movement prevention device includes: an annular member 3A having a pressing part which presses an outer surface of an existing pipe 1, in which a blocking part 5 capable of blocking flow is installed, and fixed to the existing pipe 1; and a tensile force application mechanism 3B which is disposed at an upstream side of the annular member 3A and causes a tensile force Fy to act on the annular member 3A along a direction in which the annular member 3A is inclined.SELECTED DRAWING: Figure 1
【課題】流体配管系統の更新の際、不平均力に起因した管移動を防止しつつ、工期の短縮や工費の節約を図ることが可能な管移動防止装置を合理的に構成する。【解決手段】通流を遮断可能な遮断部５が設置された既設管１の外表面を押圧する押圧部を有し、既設管１に固定された環状部材３Ａと、環状部材３Ａの上流側に配置され、環状部材３Ａを傾倒させる方向に沿って環状部材３Ａに引張力Ｆｙを作用させる張力付与機構３Ｂと、を備えている。【選択図】図１
