At present, the foundation of construction projects need to compact the loose soil, which is inseparable from tamping. What we should know when doing this work is that in fact, the tamping of the foundation of small construction projects can be completed with small electric rammers, but some large ones need to be completed with dynamic rammers. Let's talk about the advantages of dynamic compaction?

强夯已广泛运用到高速公路铁路，机场、核电站、大工业区、港口填海等基础加固工程。之所以被广泛的使用是因为它的优点工期短、效果好、造价低。强夯平时还主要是适用于处理碎石土、砂土、低饱和度的粉土与粘性土、湿陷性黄土、素填土和杂填土等地基。但是在进行这个工作之前也有很多要了解的知识点。好比说在强夯施工前，应在施工现场有代表性的场地上选取一个或几个试验区，除了做好这些的还应该要进行试夯或试验性施工。试验区数量应根据建筑场地复杂程度、建设规模及建筑类型确定。另外，强夯的优势该体现在能够对各类铁路和公路地基的强夯，在不同的工作环境下可以采取不同的方案，因地制宜，使项目平稳落地，而且工程时间短。这些都是大家要知道的。

Dynamic compaction has been widely used in highway, railway, airport, nuclear power plant, large industrial zone, port reclamation and other foundation reinforcement projects. It is widely used because of its advantages of short construction period, good effect and low cost. Dynamic compaction is also mainly applicable to the treatment of gravel soil, sandy soil, silt and cohesive soil with low saturation, collapsible loess, plain fill and miscellaneous fill. But there are many knowledge points to understand before this work. For example, before the construction of dynamic compaction, one or several test areas should be selected on the representative site of the construction site. In addition to these, trial compaction or experimental construction should also be carried out. The number of test areas shall be determined according to the complexity of the construction site, construction scale and building type. In addition, the advantage of dynamic compaction is that it can be used for dynamic compaction of various railway and highway foundations. Different schemes can be adopted in different working environments to adjust measures to local conditions, so as to make the project land smoothly and the project time is short. These are what we need to know.

强夯的方法现在很是常见，对于这方面的问题你要是不清楚的话那可以仔细阅读下的。强夯这几年它以其成本低、工期短、效果好、施工应用范围广的特点，越来越多的被用于地基施工中。以后在看到它的时候就要明白的。而且操作简单；适用土质范围广，加固效果显着，可取得较高的承载力，一般地基强度可提高2～5倍；压缩性可降低2～10倍，所以说这方面做的也都是很到位的。并且在在强夯过程中，要注意做好检查工作，比如测量放线、夯锤落距、夯点间距、夯击遍数等，工作人员一定要遵循三检制，并做好检查记录，从而保证强夯施工质量，保证整个工程质量。强夯工效高，施工速度快（一般设备每月可加固5000～10000m地基），较换上回填和桩基可缩短工期一半；节省加固原材料；整体来说的话它的施工费用低。

The method of dynamic compaction is very common now. If you don't know about this problem, you can read it carefully. In recent years, dynamic compaction has been more and more used in foundation construction because of its low cost, short construction period, good effect and wide application range. You should understand when you see it in the future. And the operation is simple; It is applicable to a wide range of soil, with remarkable reinforcement effect. It can obtain high bearing capacity, and the general foundation strength can be increased by 2 ~ 5 times; The compressibility can be reduced by 2 ~ 10 times, so the work in this regard is also in place. In addition, in the process of dynamic compaction, attention should be paid to the inspection work, such as measuring and setting out, rammer falling distance, ramming point spacing, tamping times, etc. the staff must follow the three inspection system and make inspection records, so as to ensure the construction quality of dynamic compaction and the quality of the whole project. Dynamic compaction has high work efficiency and fast construction speed (general equipment can reinforce 5000 ~ 10000m foundation every month), which can shorten the construction period by half compared with backfilling and pile foundation; Save reinforcement raw materials; On the whole, its construction cost is low.
