手動(dòng)擊實(shí)儀使用說(shuō)明：
★將擊實(shí)儀放在堅(jiān)實(shí)地面上，取制備好的試樣600～800g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規(guī)定的擊實(shí)次數(shù)進(jìn)行擊實(shí)。擊實(shí)時(shí)擊錘應(yīng)自由鉛直落下，落高也按附表4.1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)行二層及第三層的擊實(shí)，擊實(shí)后超出擊實(shí)筒的余土高度不得大于6mm。
★用修土刀沿套環(huán)內(nèi)壁削挖后，扭動(dòng)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(chēng)質(zhì)量，準(zhǔn)確至1g。
★用推土器推出擊實(shí)筒內(nèi)試樣，從試樣中處取2個(gè)各約15～20g土測(cè)定其含水量。計(jì)算至0.1%，其平行誤差不得超過(guò)1%
Manual compactor instructions:
★ Place the compactor on a solid ground, pour 600-800g of the prepared sample into the cylinder, level the surface, and press it slightly with a round wooden board, then hit the number of times according to the number of times specified in Table 4.1. real. The real-time hammer should be free to fall vertically, and the height of the hammer should be adjusted correctly according to Schedule 4.1. The hammer track must be evenly distributed on the soil surface. Then install the collar, plan the surface of the soil into a rough surface, repeat the above steps to compact the second layer and the third layer. After compaction, the height of the residual soil beyond the compaction cylinder shall not exceed 6mm.
★ After cting along the inner wall of the collar with a ripper, twist and remove the collar, carefully flatten the specimen with the top of the cylinder, and remove the bottom plate. If the bottom of the specimen exceeds the cylinder, it should be flattened. Wipe the outer wall of the cylinder and weigh it to the nearest 1g.
★ Use the bulldozer to push out the sample in the compaction cylinder, and take about 15-20g soil from the center of the sample to measure the water content. Calculated to 0.1%, the parallel error must not exceed 1%
手動(dòng)擊實(shí)儀計(jì)算與制圖說(shuō)明.
手動(dòng)輕型和手動(dòng)重型擊實(shí)儀計(jì)算方法相同。
★按下式計(jì)算擊實(shí)后各點(diǎn)的干質(zhì)量密度：.
（計(jì)算至0.01g/cm）.
式中pd——干質(zhì)量密度（g/m）；.
po——濕質(zhì)量密度（g/m）；.
w1——含水量（%）。
★以干質(zhì)量密度為縱座標(biāo)，含水量為橫座標(biāo)，繪制干質(zhì)量密度與含水量的關(guān)系曲線，曲線上峰值點(diǎn)的縱、橫座標(biāo)分別表示土的A大質(zhì)量干密度和A優(yōu)含水量。
Manual compactor calculation and drawing instructions.
Manual light and manual heavy-duty compactors are calculated in the same way.
★ Calculate the dry mass density of each point after compaction according to the following formula:
(calculated to 0.01g/cm).
Where pd - dry mass density (g / m);
Po——wet mass density (g/m);
W1 - water content (%).
★ With the dry mass density as the ordinate and the water content as the abscissa, the relationship between the dry mass density and the water content is plotted. The vertical and horizontal coordinates of the peak point on the curve indicate the A mass dry density and A water content of the soil. .
