To provide an emergency shut-off valve that can cut off water reliably and can be easily restored.SOLUTION: A water-supply pipe structure comprises: a primary water-supply pipe 4 that is connected to a main pipe, a secondary water-supply pipe 8 that is connected to an outflow side end portion of tap water, for a water meter M connected to the outflow side end portion of the tap water of the primary water-supply pipe 4; a water-supply pipe shut-off valve 7 for a water-supply pipe that is disposed between the primary water-supply pipe 4 and the water meter M or between the water meter M and the secondary water-supply pipe 8, that houses an earthquake detector, and that operates when the earthquake detector detects a predetermined magnitude of vibration generated by an earthquake to cut off a flow of the tap water; and a box 5 that can accommodate the water-supply pipe shut-off valve 7 and the water meter M, and that is buried in ground.SELECTED DRAWING: Figure 3
【課題】止水を確実に行うことができるとともに、復旧作業を容易に行える緊急遮断弁を提供する。【解決手段】本管に接続される一次側給水管４と、一次側給水管４の水道水の流出側端部に接続される水道用メータＭの水道水の流出側端部に接続される二次側給水管８と、一次側給水管４と水道用メータＭとの間又は水道用メータＭと二次側給水管８との間に配置され、地震検知器を収納し、地震により発生する所定の大きさの振動を前記地震検知器が検出することで作動して水道水の流れを遮断する給水管用遮断弁７と、給水管用遮断弁７及び水道用メータＭを収容可能であり地中に埋設されるボックス５とを設けた。【選択図】図３
