巖石膨脹壓力試驗儀試驗步驟:
■將試件放人內(nèi)壁涂有凡士林的金屬套環(huán)內(nèi),在試件上下分別放置薄型濾紙和金屬透水板。
■安裝加壓系統(tǒng)及量測試件變形的測表。
■應使儀器各部位和試件在同一軸線上,不得出現(xiàn)偏心荷載。
■對試件施加產(chǎn)生O.O1MPa壓力的荷載,測讀試件變形測表讀數(shù),每隔l0min讀數(shù)1次,直至3次讀數(shù)不變。
■加的荷載,應保持試件高度在整個試驗過程始終不變。
■開始時每隔10min讀數(shù)1次,連續(xù)3次讀數(shù)差小于0.001mm時,改為每1h讀數(shù)1次
■浸水后總試驗時間不得少于48h.
■試驗過程中,應保持水位不變。水溫變化不得大于2℃
■試驗結(jié)束后,應描述試件表面的泥化和軟化現(xiàn)象。
Rock expansion pressure tester test steps:
■Place the test piece on the inner wall of the metal collar of Vaseline,and place thin filter paper and metal permeable plate on top of the test piece.
■Installation of the pressure system and the measurement of the deformation of the test piece.
■The parts of the instrument and the test piece should be on the same axis,and no eccentric load should occur.
■Apply a load of O.O1MPa pressure to the test piece,read the deformation table reading of the test piece,and read it every l0min until the reading is unchanged.
■For the applied load,the height of the test piece should be kept constant throughout the test.
■Read every 10 minutes at the beginning,and change the readings every 1h to 1 time for 3 consecutive readings.
■The total test time after water immersion shall not be less than 48h.
■The water level should be kept constant during the test.Water temperature change must not exceed 2°C
■After the test,the muddy and softened surface of the test piece should be described.
