No matter how well the preparatory work is done in the early stage, no problems can be completely avoided in the dynamic compaction foundation treatment, especially the dynamic compaction equipment and dynamic compaction machine are bulky and complex in structure. There are no problems in the early inspection, and unexpected problems may occur in the construction process. Dynamic compaction shall check all test data and construction records during dynamic compaction construction. If they do not meet the design requirements, supplementary compaction and other effective measures shall be taken. Dynamic compaction construction will explain the treatment method for you.

强夯机有时候会发现履带掉落的情况，这种情况比较常见，强夯机长期使用或者强夯机老化的时候容易出现这类问题，这个时候就需要检查一下强夯机的引导轮看磨损是否严重，如磨损严重的话就需要更换引导轮。强夯检查强夯施工过程中的各项测试数据和施工记录，不符合设计要求时应补夯和采取其它有效措施。

The dynamic compactor sometimes finds the track falling, which is common. Such problems are easy to occur when the dynamic compactor is used for a long time or the dynamic compactor is aging. At this time, it is necessary to check the guide wheel of the dynamic compactor to see if the wear is serious. If the wear is serious, it is necessary to replace the guide wheel. Dynamic compaction shall check all test data and construction records during dynamic compaction construction. If they do not meet the design requirements, supplementary compaction and other effective measures shall be taken.

履带变松了怎么办。强夯置换其特点是：可使用工地常备简单设备；施工工艺、操作简单；适用土质范围广，加固效果显著，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，加固影响深度可达6～10m；工效高，施工速度快，较换上回填和桩基可缩短工期一半；节省加固原材料；施工费用低，节省投资，比换土回填节省50%费用，与预制桩加固地基相比，可节省投资50%～70%等。

What if the track becomes loose. The characteristics of dynamic compaction replacement are: simple equipment standing on the site can be used; Construction technology and simple operation; It is applicable to a wide range of soil, has remarkable reinforcement effect, 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, and the reinforcement influence depth can reach 6 ~ 10m; High work efficiency and fast construction speed, which can shorten the construction period by half compared with backfilling and pile foundation; Save reinforcement raw materials; The construction cost is low and the investment is saved. It can save 50% of the cost compared with soil replacement and backfilling. Compared with precast pile foundation reinforcement, it can save 50% ~ 70% of the investment.

新履带刚刚安装的时候是十分的紧的，使用时间长了之后就会变松，日常对强夯机检查时就需要时刻注意履带的松紧程度，因为履带松了就容易掉落。履带使用时间长了就更换，不长只需要更换销套就可以了。

The new track is very tight when it is just installed and will become loose after a long time of use. During the daily inspection of the dynamic compactor, it is necessary to always pay attention to the tightness of the track, because the track is easy to fall when it is loose. The track will be replaced after a long service time, and only the pin sleeve needs to be replaced after a short time.

互链板。互链板就是保护履带的那层，磨损（零部件失效的一种基本类型）厉害的话就是去了保护作用，需要直接更换.

Interlink board. The cross link plate is the layer that protects the track. If it is severely worn (a basic type of component failure), it will play a protective role and need to be replaced directly
