Before the dynamic compaction of the dynamic compaction machine, the hoisting equipment, riggings, snap rings, pins, tools and instruments shall be comprehensively inspected, and the trial hoisting and trial compaction shall be carried out. The ram lifting height limiter shall be installed on the dynamic compaction machine. The lifting ram and sling shall be vertical and uniform. The ram and hook shall not collide with the boom, and the boom shall be provided with anti ram collision protection measures. The specific steps are as follows:
1. Check whether the reinforcement is intact, whether there is wire breakage, whether the lubrication is uniform, and whether the steel wire rope joint is firmly connected.
2. The pulley block shall be well lubricated, whether the connecting pin is worn, and the end shall be firmly fixed.
3. The automatic decoupling device should be firmly connected with the steel wire rope, the joint should be checked for damage, the connecting pin should be complete without wear, and the end should have a locking card to fix the pin.
4. The legs of each section of the lifting frame shall be firmly connected, the bolt model shall meet the relevant requirements, and shall not be loose. All bolt holes shall be equipped with sufficient bolts, and there shall be no empty holes. The upper crossbeam should check whether the welding position is complete, there should be no damage, and the connecting pin should be fixed.
5. An effective protective net shall be set outside the operation room, which shall cover the entire observation window and be fixed on the observation window.
6. The mechanical counterweight should be set according to the relevant lifting requirements, and it is not allowed to change the counterweight weight without permission.
The dynamic compaction machine rental manufacturer reminds you that the matters needing attention in the construction process are that the range of dynamic compaction construction is about 80 meters, so as to ensure sufficient operation and construction. That is to say, there should be no other irrelevant personnel in this area. Warning or warning signs can be set up 100 meters around the dynamic compaction machine to avoid the interference of pedestrians and ensure the safety of the construction environment as much as possible.
Personnel working in the construction shall take protective measures, such as wearing safety helmets, confirming the contact points of some hooks and hammers, and observing whether there are factors affecting the construction around.
