表面振動壓實儀是檢測儀器，用于測定無粘性自由排水粗粒土和巨粒土（包括堆石料）的大干密度。使用前務(wù)必仔細閱讀說明書。并由**實驗人員操作，以避免操作不當引起的傷害。
Surface vibration compactor is a testing instrument for determining the large dry density of non-cohesive free-draining coarse-grained soil and giant-grained soil (including rockfill materials). Be sure to read the instructions carefully before use. It is operated by ** experimental personnel to avoid injury caused by improper operation.
表面振動壓實儀工作原理：
振動夯板在試樣表面做垂直振動壓實被自上而下傳播，顆粒菱角剪裁破碎后，顆粒位置重新排列，移動到相應于土工試驗規(guī)格標準條件下的穩(wěn)定位置，從而土體得到壓實。
Working principle of surface vibration compactor:
The vibration tamping plate is propagated vertically from the top to bottom of the sample. After the particles are cut and broken, the position of the particles is rearranged and moved to a stable position corresponding to the standard conditions of the geotechnical test.

Instructions for use of surface vibration compactor:
★ Install a suitable test cylinder and compact the test cylinder to take an appropriate amount of soil sample. Use the specified tools to load the test sample and roughly scratch the surface of the sample.
★ Make sure that the power of the three-phase line is well connected, and the power indicator on the controller panel is on.
★ Press the up, stop and down buttons on the controller, the vibration motor and the weights move freely.
★ When pressing the ascending switch, the vibrator will fall down or pressing the down switch, the vibrator will rise instead, the power cord should be inverted. Otherwise, the upper and lower stroke switches will not work, and it is easy to damage the machine.
★ Press the down button once, the large sliding sleeve drives the vibration plate and tamping plate to drop. When the tamping plate contacts the loose soil sample, the large sliding sleeve will continue to fall, and it will drop to the lower end of the sliding sleeve, 15-25mm away from the vibration plate flange When you press the stop button once, the large slide sleeve stops descending.
★ Set the timer on the controller. The set time is 6 minutes. Press the vibration switch to start the vibration. The timer displays the vibration time. After 6 minutes, the moving plate will automatically stop.
★ Press the up button, the sleeve will drive the vibrating plate, the tamping plate will rise, and it will rise to 15-25mm below the top box of the stop block. Press the stop button once, and the big slide will stop rising.
★ Add a second soil sample in accordance with the test procedures, repeat the above operation steps twice, and one sample ** is calculated as the vibration compaction is completed.

表面振動壓實儀使用注意事項:
1、本機安裝時,A好澆注混凝土基礎(chǔ)上,以求機器工作穩(wěn)定,在混凝土基位上 墊 8-10mm 橡膠板,以減輕振動。
2、在滑動部分及有黃油咀部位定加潤滑油脂. 每次操作試驗前應清除立柱外表面灰塵,應加注機械油20#。
Notes on the use of surface vibration compactor:
1. When the machine is installed, A should be poured on the concrete foundation to ensure the stable operation of the machine. Place 8-10mm rubber plate on the concrete base to reduce vibration.
2. Add lubricating grease to the sliding part and the part with a grease nipple. Before each operation test, the dust on the outer surface of the column should be removed, and mechanical oil 20 # should be filled.
