Dynamic compaction machine is a machine for compaction of fill. There are many types of dynamic compaction machines, such as frog type, vibration type, step type, etc. the construction unit uses different types of dynamic compaction machines according to the needs of the project. When the construction personnel operate the dynamic rammer, the impact force produced by the high drop of the heavy hammer is used to press the gravel into the soil

地中，那么在施工中需要注意的哪些事项？强夯机租赁

In the ground, what should be paid attention to in the construction?

(1)施工人员在开始施工之前先佩戴好帽，并且穿戴好必要的保护用品;

(1) Construction personnel should wear safety helmet and necessary protective equipment before construction;

(2)施工人员在施工现场需要进行的规划，并且根据设计图纸严格施工，同时保证现场道路的平坦、坚实、畅通，如有危险地区，应用显著的标记标明;

(2) The construction personnel need to carry out comprehensive planning on the construction site, and strictly carry out construction according to the design drawings. At the same time, ensure that the site road is flat, solid and smooth. If there are dangerous areas, they should be marked with obvious marks;

(3)操作强夯机的施工人员必须在经过培训后并具有上岗证书后才能开始操作，还能了解强夯机的构造、性能、操作规程，在使用过程中能维护保养和排除一般故障。

(3) The construction personnel who operate the dynamic compaction machine must have professional training and work certificate before starting operation. It is better to understand the structure, performance and operation rules of the dynamic compaction machine, and be able to maintain and eliminate general faults in the process of use.

(4)施工单位在强夯机上专门设置吊臂撑杆系统，减小吊锤机械吊臂在夯锤下落时的晃动及反弹。为了起见，施工者在每次施工前都应该检查吊锤机械各部位是否正常及钢丝绳有无磨损等情况，发现问题需要及时处理。

(4) It is better for the construction unit to set the boom strut system on the dynamic compaction machine to reduce the shaking and rebound of the mechanical boom of the hammer when the hammer falls. For the sake of safety, the constructors should check whether all parts of the lifting hammer machine are normal and whether the steel wire rope is worn before each construction, and timely handle the problems found.

(5)施工人员需在强夯机停稳后开始强夯工作，并且保证起吊的夯锤匀速落下夯锤或挂钩不得碰吊臂，应在适当位置挂废汽车外胎加以保护。

(5) The construction personnel shall start the dynamic compaction work after the dynamic compaction machine stops stably, and ensure that the lifted rammer falls down at a constant speed. The rammer or hook shall not touch the crane arm, and the tire of the waste truck shall be hung at an appropriate position for protection.

(6)施工单位在干燥气候下作业时，应在夯击附近的地面上洒水增加湿度。强夯机的驾驶室前面需设置防护罩，前提是不能遮挡住驾驶人员的视线。驾驶人员为了操作应佩戴防护眼镜，避免夯锤弹起砂石，击碎驾驶室玻璃伤害驾驶员的眼睛。

(6) When working in dry climate, the construction unit should spray water on the ground near the ramming to increase the humidity. A protective cover should be set in front of the cab of the dynamic compaction machine, on the premise that the driver's sight can not be blocked. In order to operate safely, the driver should wear protective glasses to avoid pounding sand and gravel, breaking the cab glass and damaging the driver's eyes.
