When dynamic compaction is used to treat the foundation, it is necessary to set the spacing of compaction points in advance. If the spacing is not set in advance, chaos will appear at the beginning of the construction, and the compaction will not be strong. However, many people don't know how to set the spacing of tamping points. How to set the spacing of tamping points?

要设定好夯点的间距，通常是取决于地基的性质，也就是说假如地基土层的透水性十分强，或者是土层十分薄，且在全部地基当中含有很多的沙质土时，那么这个夯点的间隔设定为是5米到10米之间，这样可能便利施工。反之，假如全部土层的透水性十分差，而且土层也是十分厚的，含水量又十分高，那么这个时候就须要把全部夯点的间隔设定为是7米到15米之间，而且夯点的位置应当安排为是不规矩的多少何图形，这样才干便利施工。

To set the spacing of tamping points, it usually depends on the nature of the foundation. That is to say, if the permeability of the foundation soil layer is very strong, or the soil layer is very thin, and there is a lot of sandy soil in the whole foundation, then the spacing of the tamping points is set between 5M and 10m, which may facilitate the construction. On the contrary, if the water permeability of all soil layers is very poor, and the soil layer is also very thick, and the water content is very high, then at this time, it is necessary to set the interval of all tamping points to be between 7 meters and 15 meters, and the position of tamping points should be arranged as irregular, so as to facilitate construction.

总之，对夯点间距的设定，须要依据土层的性质来抉择的。假如在一直定土层的性质之前，就随便设定好夯点，这是错误的，因为土层有不一样品种的，透水性也是有相差的，所以对夯点的间距设定，这些基本的信息是须要理解到的，不然就很难设定。

In short, the setting of tamping point spacing should be based on the nature of soil layer. It is wrong to set the tamping point before determining the nature of the soil layer. Because there are different kinds of soil layers and different water permeability, it is necessary to understand the basic information of setting the spacing of tamping points, otherwise it is difficult to set it.

另外，强夯施工当中，还有很多的也是须要留神的，不单单是间距的问题，其余的间隔也是须要留神的。因为强夯施工不同于其余的施工方法，用到的大局部是大型的工具，所以一定要留神间距的坚持，假如不能保障间距，就会导致彼此碰撞，甚是影响到施工的后果。

In addition, dynamic compaction construction, there are many key points also need to pay attention to, not only the spacing problem, the rest of the spacing also need to pay attention to. Because dynamic compaction construction is different from other construction methods, most of which are large tools, we must pay attention to the persistence of spacing. If the spacing can not be guaranteed, it will lead to mutual collision and even affect the consequences of construction.
