Dynamic compaction method has been widely used in foundation reinforcement projects such as expressways, railways, airports, nuclear power plants, large industrial areas and port reclamation, but the construction process is mainly controlled by human factors. For example, the orientation of tamping points depends more on the experience of operators, and it is unable to monitor the tamping times, tamping settlement and other data parameters of each tamping point, which has the defects of repeated operation and low construction efficiency. Through the integration of construction management system on dynamic compaction equipment and information technology, it can help operators operate the equipment more accurately and make better use of the machine.

Its effect is to receive and process the sensor data, send the processed data to the tablet for display, and send the construction data to the background cloud service monitoring center through 4G antenna for processing.

5.通讯模块通讯模块由4G天线组成，其效果是实时传输施工数据到后台云服务监控中心进行处理。

5. Communication module the communication module is composed of 4G antenna. Its effect is to transmit construction data in real time to the background cloud service monitoring center for processing.
