三、操作步驟：
? 將試樣固定在V型鐵上，從右端插入試棒使一端露出20mm，拴好鏈繩。
? 輕微搖動(dòng)手輪使V型鐵上水平泡處于水平位置。
? 打開(kāi)角度尺緊固栓，轉(zhuǎn)動(dòng)角度尺使角度尺與副尺歸零，擰緊緊固栓。
? 順時(shí)針搖動(dòng)手輪，使V型鐵緩慢傾斜，直至試棒滑動(dòng)為止。
? 記錄下角度尺示值。
? 逆時(shí)針搖動(dòng)手輪，使V型鐵水平為止。
? 將試棒拉出通信管外露20mm。
? 按照以上操作步驟連續(xù)9次，計(jì)算出9次平均值。（傾斜角度≤14°4′依據(jù)JT/T683-2009《通信管道靜摩擦系數(shù)測(cè)量?jī)x》之規(guī)定要求）
Third, the operation steps:
? Fix the sample on the V-shaped iron, insert the test rod from the right end so that one end is exposed 20mm, and fasten the chain rope.
? Slightly shake the handwheel to make the horizontal bubble on the V-shaped iron in the horizontal position.
? Open the fastening pin of the angle ruler, turn the angle ruler to zero the angle ruler and the vice ruler, and tighten the fastening pin.
? Shake the handwheel clockwise to tilt the V-shaped iron slowly until the test rod slides.
? Record the displayed value of the angle ruler.
? Turn the handwheel counterclockwise until the V-shaped iron is level.
? Pull the test rod out of the communication tube to expose 20mm.
? Follow the above steps for 9 consecutive times and calculate the average of 9 times. (Tilt angle ≤14 ° 4 ′ according to the requirements of JT / T683-2009 "Communication Pipe Static Friction Coefficient Measuring Instrument")
