手动重型击实仪适用于按GB/T 50123-1999《土工试验方法标准》、JTJ 051-93《公路土工试验规程》等标准中制作土工试样时手工击实之用（试样用于承载比试验，回弹模量试验等），击实仪分轻型和重型两种，轻型击实适用于粒径≤5mm的粘性土，重型击实适用于粒径≤20mm的土，采用三层击实时，A大粒径≤40mm。

The manual heavy-duty compactor is suitable for manual compaction when making geotechnical specimens according to GB/T 50123-1999 "Test Methods for Geotechnical Methods" and JTJ 051-93 "Technical Rules for Highway Geotechnical Engineering" (samples are used for carrying Specific test, rebound modulus test, etc.), the compactor is divided into light and heavy. The light compaction is suitable for cohesive soil with particle size ≤5mm. Heavy-duty compaction is suitable for soil with particle size ≤20mm. In real time, A large particle size ≤ 40mm.

手动重型击实仪计算与制图说明.

手动轻型和手动重型击实仪计算方法相同。

（1）按下式计算击实后各点的干质量密度：.

（计算至0.01g/cm）.

式中pd——干质量密度（g/m）；.

po——湿质量密度（g/m）；.

w1——含水量（%）。

（2）以干质量密度为纵座标，含水量为横座标，绘制干质量密度与含水量的关系曲线，曲线上峰值点的纵、横座标分别表示土的A大质量干密度和A优含水量。

Manual heavy-duty instrument calculation and drawing instructions.
Manual light and manual heavy-duty compactors are calculated in the same way.
(1) 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 (%).
(2) The dry mass density is the ordinate and the water content is 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 of the soil. Water content.

手动重型击实仪使用说明：

★将击实仪放在坚实地面上，取制备好的试样600～800g倒入筒内，整平其表面，并用圆木板稍加压紧，然后按附表4.1规定的击实次数进行击实。击实时 应自由铅直落下，落高也按附表4.1调试正确，锤迹必须均匀分布于土面。然后安装套环，把土面刨成毛面，重复上述步骤进行中层及第三层的击实，击实后超出击实筒的余土高度不得大于6mm。

★用修土刀沿套环内壁削挖后，扭动并取下套环，齐筒顶细心削平试样，拆除底板，如试样底面超出筒外亦应削平。擦净筒外壁，称质量，准确至1g。

★用推土器推出击实筒内试样，从试样中处取2个各约15～20g土测定其含水量。计算至0.1%，其平行误差不得超过1%

Manual heavy-duty 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 cultivating 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%
