The purpose of dynamic compaction machine construction disposal is to eliminate the local collapsibility of the foundation and reduce the total collapsibility of the foundation to be disposed. The remaining collapsibility of the untreated collapsible loess layer in the lower part shall not be greater than the planning rule value. Let's see how to standardize the use of Leibo dynamic compactor equipment to reduce the uneven settlement of the foundation.

一、强夯机缩短工期。经历标明，经强夯一遍，可使5~12m厚的砂质冲击层产生霎时沉降15~50cm；再夯一遍，又可产生瞬时沉降约为初始沉降的60%。这种逼迫沉降的速度是普通其他方法所不能比拟的。每台设备加固地基的功率平均每天为300~600m，当强夯设备退场时，地基上各种路基工程和构造工程可立刻开端，无须等候。

1、 The dynamic compaction machine will shorten the working period. Experience shows that after dynamic compaction, the 5 ~ 12m thick sandy impact layer can instantly settle 15 ~ 50cm; Tamping again can produce instantaneous settlement, which is about 60% of the initial settlement. This forced settlement speed is unmatched by other ordinary methods. The average power of each equipment to strengthen the foundation is 300 ~ 600m per day. When the dynamic compaction equipment leaves the site, various subgrade works and structural works on the foundation can be started immediately without waiting.

二、削减不平均沉降。经过一系列平均的夯击及严厉的施工操控，地基土体紧缩性可降低2~10倍，大大改良了地基的平均性，能使雷博强夯机加荷后的地基差别沉降值操控在规则极限以内，即在工程运用上能够疏忽不计地基的差别沉降。

2、 Reduce uneven settlement. The average settlement of the foundation can be reduced by less than 10 ~ 2 times after the application of the dynamic compaction machine, which can greatly reduce the difference of the average settlement of the foundation.
