The speed of dynamic compaction construction is affected by certain factors. Each of these factors can affect the efficiency of dynamic compaction construction. Let's take a look at the three factors that affect the dynamic compaction construction together with the construction of dynamic compaction machine.
1. Dynamic compaction energy
If the tamping strength is not enough, the foundation foundation can not be compacted and the foundation gap is not completely disappeared. The tamping strength generally depends on the ramming height of the rammer and the weight of the rammer itself.

2. Contact surface of rammer
The larger the contact surface of the rammer is, the better it is in line with the actual situation of the foundation. It mainly depends on the static pressure of the rammer. Static pressure refers to that when the static pressure is less than the standard range, ramming the ground will lead to the appearance of firm, low and soft. Is the greater the static pressure, the better it is. However, when the static pressure is about a certain point, it can also lead to the excessive tamping force of the rammer falling into the foundation It is difficult to pull out.
3. Properties of foundation
The dynamic compaction company should adopt the combat policy according to the circumstances, treat the problems with scientific instruments and cautious thinking mood, and try to analyze the structure, composition and environment of the foundation, so as to judge the method used.
