What problems should we pay attention to when leasing dynamic compactors? In fact, in construction projects, dynamic compactors are often used because of the need to compact loose soil. There are many types of power compactors, including frog type, vibrating type, jumping type, tamping type and heavy hammer type. According to the needs of the project.
During the construction of dynamic compaction machine, the tamping points shall have obvious symbols and numbers, and the allowable error of tamping point positioning shall be ± 50mm. When the vibration during dynamic compaction has an impact on nearby buildings, monitoring points shall be set up and vibration isolation measures such as vibration isolation or vibration ditch excavation shall be taken.
The connection point ramming and full ramming schemes are adopted for dynamic compaction. The spot pressure shall be carried out twice, and each compaction energy is 1000KN? m. The number of blows per time shall not be less than 3. Before and after compaction, the foundation soil shall be tested by standard penetration test, static penetration test, load test, etc.
Analyze and sort out the measured data so as to lease the dynamic compaction machine. Through comparison, it is determined that the total tamping energy of a single point is related to the tamping penetration, tamping point spacing, tamping times and the effective reinforcement depth at the interval of tamping times
The above is the introduction of relevant materials of dynamic compaction machine. I hope the above content can help you. More relevant information will be collated and published on the website in succession, so you can follow our website http://www.sddhfjx.cn consulting service
