Dynamic compaction machine is a kind of machine for loose soil compaction in construction engineering. It is often used for treatment. There are many types of dynamic compaction machine, including frog type, vibrating type, step type, ramming type and hanging hammer type. According to the needs of engineering, different types of dynamic compaction machine are used.
The safe operation is as follows:
1. The construction site shall be planned comprehensively, and the construction site plan shall be provided. The site shall be flat, level, level and cross, and the dangerous area shall be marked.
2. All kinds of mechanical and electrical equipment operators must be trained, assessed and certified to understand the mechanical structure, performance, operation procedures, maintenance, troubleshooting and other general faults.
3. Drivers and business operators must obtain approval or business license from relevant departments before driving vehicles. Other drivers are not allowed to drive or start the car without permission.
4. Operators of lime powder, lime screening and using cement must wear masks, glasses, gloves, etc.
5. The power supply of electrical equipment shall be erected and installed in accordance with relevant regulations. Electrical equipment should have good grounding and zero grounding resistance, not more than 4 ohm, and be equipped with reliable electric shock protection device.
6. Tampering with cables is strictly prohibited during tampering operation.
7. In order to reduce the swing and rebound of the mechanical boom when hammering, the boom support system should be specially set. Before starting the machine every day, it is necessary to check whether the mechanical part of the hammer is normal and whether the wire rope is worn, so as to find out the problems in time.
8. After dynamic compaction, the speed of lifting the hammer should be uniform, and the hammer or hook should not touch the arm, which should be used to protect the car from hanging waste tires.
9. Pounds, boom and Hammer no less than 15 million. Non personnel shall be 30 m away from the tamping point. Dynamic compaction machine construction team
