BALL-PASSING TEST PIECE AND METHOD FOR USING BALL-PASSING TEST PIECE
To provide a ball-passing test piece for a drain pipe that prevents an identification medium from falling and facilitates avoiding water damage.SOLUTION: A test piece T comprises a spherical buoyant piece T1, and a spherical and hollow first container T2 that covers an entire circumference of the buoyant piece T1. The buoyant piece T1 includes: a weight T11 that is attached such that the center of gravity of the whole is lowered; and a sheet-like identification medium T12 that is attached so as to be located higher than the center of gravity. The first container T2 includes a dewatering hole T21 for draining water that has flooded inside.SELECTED DRAWING: Figure 2
【課題】識別媒体の落下を予防し、かつ水損を回避しやすい排水管の通球試験体を提供することにある。【解決手段】試験体Ｔは、球状の浮力体Ｔ１と、浮力体Ｔ１の全周を覆う球状かつ中空状の第１容器Ｔ２とを備え、浮力体Ｔ１は、全体の重心を低くするように取り付けられた錘Ｔ１１と、上記重心より高く位置するように取り付けられたシート状の識別媒体Ｔ１２とを有し、第１容器Ｔ２は、内部に浸水した水を抜く脱水孔Ｔ２１を有する。【選択図】図２
