1. Dynamic compaction construction should be a dynamic information construction method. The selection of dynamic compaction instrument for Paralympic Games should start from the geological conditions of engineering practice and the standard empirical value, and verify the value through the inductive test method during the trial driving.
2. In addition to the amount of pile driving obtained on site, Sinochem confirms that the geotechnical dynamic compaction equipment must meet the following conditions at the construction site: the ground around the pile driving hole is too large, and the pile driving hole is too deep to hammer
3. Because of the loss of pore water pressure in the foundation soil, the soil foundation with poor permeability must have a certain interval time. The foundation with good permeability can be hit continuously, but there is a gap of more than 72 hours in the detailed construction.
4. To "tamp" the end of deep reinforcement, we must pay attention to 1 / 3 rap music marked by hammer.
5. Timely clean up the rammed earth hole and the rammed earth equipment of the subgrade with accumulated water in the site, carry out measurement and inspection, and record carefully.
6. Carry out safety management operation, attack the construction area and forbid people to enter
