强夯与冲击碾压一般在选择使用的时候都是需要根据实际环境情况的考察来看下，有些环境使用强夯好，而有一些则冲击碾压比较好些，下面强夯机租赁人员就来讲解下具体的实际情况吧。

In general, dynamic compaction and impact rolling are selected according to the actual environmental conditions. Some environments are better for dynamic compaction, while others are better for impact rolling. Next, lease personnel of dynamic compaction machine will explain the specific actual conditions.

1、填土厚度。市场流行的强夯处理深度大能到10m，而冲击碾压处理深度一般不大于1.5m，这样的话如果处理回填土，两种工艺都能用，但是处理2m以上原地基的话强夯有明显的优势，起码它不用把原土再重新开挖一遍，要是用冲碾的话处理深度达不到，需要开挖再分层回填碾压。

1. Fill thickness. The popular dynamic compaction treatment depth in the market can reach 10m, while the impact compaction treatment depth is generally not more than 1.5m. In this way, if the backfill is treated, both processes can be used. However, if the original foundation is treated more than 2m, dynamic compaction has obvious advantages. At least, it does not need to excavate the original soil again. If the treatment depth is not reached with the impact compaction, it needs to excavate and then backfill and roll in layers.

2、处理特殊地形。处理溶洞、落水洞、地面塌陷等强夯有它独特的优势。

2. Handling special terrain. It has its unique advantages to deal with karst cave, sinkhole, ground collapse and other dynamic compaction.

3、边角地带或者施工区域小的地方。冲击碾压施工过程中冲击压路机需要把速度控制在12-15km/h，地方小或者狭长，转弯半径不够的话，在速度提不起来的地方压实效果会降低，另外，边边角角的地方冲击碾压也影响不到，所以一般场地即使施工工艺选用冲碾，也会用强夯配合封边。

3. Corner area or small construction area. During the impact rolling construction, the impact roller needs to control the speed at 12-15km/h. If the place is small or narrow, and the turning radius is not enough, the compaction effect will be reduced in the places where the speed cannot be raised. In addition, the impact rolling at the corners will not be affected. Therefore, even if the construction process is impact rolling, the general site will also use dynamic compaction to seal the edges.

 

 

4、湿陷性黄土。强夯冲击能大，可以使土体结构发生显著变化，将地基土重新固结，一定程度上能黄土湿陷性，冲击碾压冲击能较小，不易破坏土体结构。

4. Collapsible loess. The impact energy of dynamic compaction is large, which can significantly change the soil structure. Reconsolidation of foundation soil can eliminate the collapsibility of loess to a certain extent. The impact energy of impact rolling is small, which is not easy to damage the soil structure.

5、不均匀沉降。强夯是以一定间距布点，对土体进行挤密夯实，冲击碾压是在作业面连续冲击，相比之下冲击碾压对不均匀沉降的效果更好。如果是有边坡强烈建议用冲碾。

5. Uneven settlement. Dynamic compaction is to arrange points at a certain distance to compact and compact the soil. Impact rolling is a continuous impact on the working face. Compared with impact rolling, it has a better effect on uneven settlement. If there is a slope, it is strongly recommended to use impact roller.

此外对周围环境也有很大的影响。这个大家都能理解，强夯的冲击能强，如果周围建筑物密集的话还是冲碾好用。更多使用注意事项就来我们网站http://www.sddhfjx.cn咨询了解吧！

In addition, it also has a great impact on the surrounding environment. Everyone can understand that the impact energy of dynamic compaction is strong. If the surrounding buildings are dense, it is better to use the impact roller. More usage precautions come to our website http://www.sddhfjx.cn Ask and understand!
