mso-hansi-font-family:"Times New Roman"">一、產(chǎn)品簡介：

mso-hansi-font-family:"Times New Roman"">輕型擊實儀研發(fā)的新一代試驗儀器。試驗的目的是用規(guī)定的擊實方法( mso-hansi-font-family:"Times New Roman"">輕型擊實法和重型擊實法) "Times New Roman"">，測定土的含水量與質(zhì)量密度的關(guān)系，從而確定該土的最優(yōu)含水量與相應(yīng)的最大干密度。

mso-hansi-font-family:"Times New Roman"">三、手動輕型擊實儀操作步驟：

(1)將擊實儀放在堅實地面上，取制備好的試樣600 mso-hansi-font-family:"Times New Roman"">～800g "Times New Roman"">倒入筒內(nèi)，整平其表面，并用圓木板稍加壓緊，然后按附表4.1 "Times New Roman"">規(guī)定的擊實次數(shù)進(jìn)行擊實。擊實時擊錘應(yīng)自由鉛直落下，落高也按附表4.1 "Times New Roman"">調(diào)試正確，錘跡必須均勻分布于土面。然后安裝套環(huán)，把土面刨成毛面，重復(fù)上述步驟進(jìn)行第二層及第三層的擊實，擊實后超出擊實筒的余土高度不得大于6mm mso-hansi-font-family:"Times New Roman"">。

(2)用修土刀沿套環(huán)內(nèi)壁削挖后，扭動并取下套環(huán)，齊筒頂細(xì)心削平試樣，拆除底板，如試樣底面超出筒外亦應(yīng)削平。擦凈筒外壁，稱質(zhì)量，準(zhǔn)確至1g mso-hansi-font-family:"Times New Roman"">?！?/span>

(3)用推土器推出擊實筒內(nèi)試樣，從試樣中心處取2 mso-hansi-font-family:"Times New Roman"">個各約15 "Times New Roman"">～20g土測定其含水量。計算至0.1% mso-hansi-font-family:"Times New Roman"">，其平行誤差不得超過1% "Times New Roman"">。　　

(4)按(1) mso-hansi-font-family:"Times New Roman"">～(3) "Times New Roman"">步驟進(jìn)行其它不同含水量試樣的擊實試驗。
