液压冲击夯与强夯机是两种不同的设备，其工作原理都是利用动能转化为冲击能来夯实土壤，只是在冲程和频率上有所不同。液压冲击夯的夯击冲程约为200~1600mm，频率快，可达30次/分钟左右，而强夯机的冲程可高达十数米，而频率则低，可视为单个的脉冲。下面来讲讲液压式强夯机处理强度的相关内容吧。

Hydraulic impact rammer and dynamic rammer are two different equipment. Their working principle is to use kinetic energy to convert into impact energy to tamp the soil, but they are different in stroke and frequency. The tamping stroke of hydraulic impact rammer is about 200~1600mm, and the frequency is fast, up to about 30 times / minute. While the stroke of dynamic rammer can be as high as more than ten meters, and the frequency is low, which can be regarded as a single pulse. Let's talk about the treatment strength of hydraulic dynamic compaction machine.

液压冲击夯是一种新型的路基、地基夯实设备，可以搭配挖掘机和装载机使用，有效深度可以达到10m，夯击频率快，转场方便，要比强夯机更加，效率更高。液压高速强夯机的工作原理与所有压实机的工作原理基本相同，利用动能转化为冲击能进行压实作业，即通过重锤反复提升下降，夯实基础或填筑土石，从而达到提高密度的目的，但这里的重锤工作高度仅有3700mm作用，利用液压加力达到锤击压实效果。

Hydraulic impact rammer is a new type of subgrade and foundation tamping equipment, which can be used with excavators and loaders. The effective depth can reach 10m, the tamping frequency is fast, and the transfer is convenient. It is safer and more efficient than the dynamic rammer. The working principle of the hydraulic high-speed dynamic compactor is basically the same as that of all compactors. The kinetic energy is converted into impact energy for compaction, that is, the heavy hammer is repeatedly lifted and lowered to tamp the foundation or fill earth and stone, so as to achieve the purpose of improving the density. However, the working height of the heavy hammer here is only 3700mm, and the hydraulic force is used to achieve the hammering compaction effect.

液压冲击夯外锤头始终与夯实面直接接触，可避免冲击下落所产生的潜在危险和碎片飞溅，作业点快速转移可通过挖掘机或装载机实现。

The external hammer head of the hydraulic impact rammer is always in direct contact with the tamping surface, which can avoid the potential danger and debris splash caused by impact falling. The rapid transfer of the operation point can be realized by excavator or loader.

液压冲击夯的应用弥补了局部区域，特别是桥台背及涵洞侧的回填中，往往因为作业面积相对较小且填土形状不规则，冲击压路机无法进入施工，传统强夯对要压实区域周边构造物影响太大，导致难以实现压实作业而造成的质量隐患，有效提高回填土压实效果,减小因工后沉降,避免通车后桥头跳车现象的发生。

The application of hydraulic impact compaction makes up for the quality hidden dangers caused by the difficult compaction operation in local areas, especially in the backfilling at the back of the abutment and the side of the culvert. Because the working area is relatively small and the filling shape is irregular, the impact roller can not enter the construction. The traditional dynamic compaction has too much impact on the surrounding structures in the area to be compacted, which effectively improves the compaction effect of the backfill and reduces the post construction settlement, Avoid bumping at bridgehead after opening to traffic.

依据国内当前的施工工艺，在路面工程高填方路基工程项目的工程施工地区，传统式的方案设计手工艺品是冲击碾压和静压桩。这二种工业设备存有工业设备进到当场不便、静压桩成本相对高、管理方法不方便等问题。如果不做好科学合理的推进，自然工后混凝土裂缝不容易避免，造成路面工程混凝土裂缝。

According to the current domestic construction technology, in the construction area of high fill subgrade project of pavement engineering, the traditional scheme design handicrafts are impact rolling and static pressure pile. These two kinds of industrial equipment have some problems, such as inconvenient access to industrial equipment on the spot, relatively high cost of static pressure piles, inconvenient management methods and so on. Without scientific and reasonable promotion, concrete cracks after natural construction are not easy to avoid, resulting in concrete cracks in pavement engineering.

强夯机租赁人员认为液压冲击夯据液压缸将夯锤提升到一定的高度，随后快速释放出。夯锤在加快着陆的整个过程中，依据夯板间接性压实地面。液压冲击夯设备安装坐落于一般小叉车的动臂上，行動便捷，可点一下或持续夯实工作台面，进行高频率高耐磨夯实工作中，有效深度可到达10m，充分保证了夯实的预期效果。

The dynamic compaction machine leasing personnel believe that the hydraulic impact rammer will lift the rammer to a certain height according to the hydraulic cylinder, and then release it quickly. During the whole process of accelerating landing, the rammer compacts the ground indirectly according to the ramming plate. The hydraulic impact tamping equipment is installed on the boom of the general small forklift. It is easy to move. It can tamp the worktable once or continuously. In the high-frequency and high-wear-resistant tamping work, the effective depth can reach 10m, which fully ensures the expected effect of tamping.
