LEVELING STRING STRETCHING JIG FOR CREEPAGE MEASUREMENT
To provide a leveling string stretching jig for creepage measurement that obtains an accurate reference line without a leveling string contacting a rail, even when the rail is higher than a reference pile.SOLUTION: Provided is a leveling string stretching jig for creepage measurement 1 for stretching a leveling string based on a reference pile line provided on a reference pile when measuring the creepage of a railroad rail. A clamp block and a fixing knob bolt 14 which are fixing parts to be fixed to the reference pile are installed along with a first leveling string raising groove part 11a1, a second leveling string raising groove part 11a2, and a third leveling string raising groove part 11a3, which are leveling string raising parts that raise the leveling string to a position above the clamp block and the fixing knob bolt 14 and higher than the reference pile.SELECTED DRAWING: Figure 1
【課題】基準杭よりもレールが高い場合でも、水糸がレールに接触することなく、正確な基準線を得るふく進測定用水糸張設治具を提供する。【解決手段】鉄道レールのふく進測定の際、基準杭に設けられた基準杭線に基づいて水糸を張設するためのふく進測定用水糸張設治具１であって、基準杭に固定される固定部であるクランプ用ブロックや固定用ノブボルト１４が設けられていると共に、クランプ用ブロックや固定用ノブボルト１４よりも上方であって基準杭よりも高くなる位置に水糸をかさ上げする水糸かさ上げ部である第１水糸かさ上げ溝部１１ａ１、第２水糸かさ上げ溝部１１ａ２および第３水糸かさ上げ溝部１１ａ３を設けている。【選択図】図１
