在建筑工程中因为需求对松土压实处理，往往运用强夯机处理，强夯机品种有许多，有蛙式，有轰动式，有跃步式，有打夯式，还有吊重锤击式，依据工程需求，所以运用不同类型的强夯机。下面强夯机租赁厂家来讲讲强夯机施工原理以及施工多项注意事项。

In construction projects, because of the need for loose soil compaction, dynamic compactors are often used. There are many types of dynamic compactors, including frog type, sensational type, leaping type, ramming type, and hanging hammer type. According to the needs of the project, different types of dynamic compactors are used. Next, let's talk about the construction principle of the dynamic compactor and several construction precautions.

强夯机施工原理

Construction principle of dynamic compaction machine

强夯置换是强夯用于加固饱满软粘土地基的办法。强夯置换法的加固机理与强夯法不同，它是运用重锤高落差发生的高冲击能将碎石、片石、矿渣等功用较好的资料强力挤入地基中，在地基中构成一个一个的粒料墩，墩与墩间土构成复合地基，

Dynamic compaction replacement is a method for strengthening saturated soft clay foundation. The strengthening mechanism of dynamic compaction replacement method is different from that of dynamic compaction method. It uses the high impact energy generated by the height drop of the heavy hammer to forcibly squeeze the gravel, rubble, slag and other useful data into the foundation, forming one granular pier in the foundation, and the soil between the piers forms a composite foundation,

以进步地基承载力，减小沉降。在强夯置换过程中，土体结构损坏，地基土体发生超孔隙水压力，但随着时刻的添加，土体结构强度会得到康复。粒料墩一般都有较好的透水性，利于土体中超孔隙水压力散失发生固。

To improve the bearing capacity of the foundation and reduce the settlement. In the process of dynamic compaction replacement, the soil structure is damaged, and the foundation soil has excess pore water pressure. However, with the addition of time, the soil structure strength will recover. Granular material piers generally have good water permeability, which is conducive to the loss of excess pore water pressure in the soil and consolidation.
