According to the present situation of dynamic separation construction in China, in general, 1000-3000kn · M / m2 can be used for coarse-grained soil, 1500-4000knm / m2 for fine-grained soil, and it is more economical to use single click compaction energy less than 3000knm. Under the same single click energy (mechanical lifting energy), heavy hammer with low drop distance is better than light hammer with high drop distance.

一般情况下，夯击点间距取决于基础布置、加固土层厚度和土质等条件。加固土层厚、土质差、透水性弱、含水率高的粘性土，夯点间距宜大，如果夯击点太密，相邻夯击点的加固效应将在浅处叠加而形成硬壳层，影响夯击能向深部传递；加固土层薄、透水性强、含水量低的砂质土间距宜小些。

In general, the distance between ramming points depends on the foundation layout, the thickness of reinforced soil layer and soil quality. For the cohesive soil with thick soil layer, poor soil quality, weak water permeability and high water content, the distance between tamping points should be large. If the tamping points are too dense, the reinforcement effect of adjacent tamping points will be superimposed in the shallow to form a hard shell layer, which affects the transfer of tamping energy to the deep. For the sandy soil with thin soil layer, strong water permeability and low water content, the distance should be smaller.

通常夯击点间距取夯锤直径的3倍，一般一遍夯击点间距为5～9m，以后各遍夯击点可与一遍相同，也可适当减小。对处理深度较深或单击夯击能较大的工程，一遍夯击点间距宜适当增大。

Generally, the distance between the ramming points is 3 times of the diameter of the rammer. Generally, the distance between the ramming points in one pass is 5-9m. The ramming points in each pass can be the same as that in the next pass, or can be reduced appropriately. For projects with deeper treatment depth or greater energy of single tamping, the spacing of tamping points should be increased appropriately.

对于中小规模的工程，江西强夯施工队会对工程进行质量检查，尤其是检查施工质量，此表要由单位现场负责人填写，质量管理主要是图纸会审，技术交底，施工组织设计，工序交接等质量评定制度。

For small and medium-sized projects, Jiangxi dynamic compaction construction team will check the quality of the project, especially the construction quality. This form should be filled in by the person in charge of the unit. The quality management mainly includes the quality evaluation system of joint review of drawings, technical disclosure, construction organization design, process handover, etc.
