The water gushed or overflowed during excavation may also increase the water volume in the geological body due to human activities. Groundwater has a great influence on the bearing capacity of foundation soil. On the one hand, this is not conducive to project construction. On the other hand, groundwater is also the main source of land subsidence and depressions.
The non-uniformity of groundwater level has a significant impact on the progress and quality of dynamic compaction construction. When dynamic compaction is carried out, it is because the existence of groundwater will cause impact during construction, or the purpose of compaction cannot be achieved during construction. In this case, the construction of soil will have a certain impact.
When groundwater is treated during construction, water collecting wells can be used for drainage. Of course, some dynamic compaction construction teams will use the method of "digging drainage ditches" for drainage, so that when the drainage conditions are better, there will be better construction methods. During construction, ensure that the drainage is clean and the soil layer is monotonous, otherwise it will cause drainage.
The reason is that rubber is formed in the soil or the bearing capacity of the foundation is reduced. In this way, the project is also a risk, and we should try our best to prevent this situation. The realization of dynamic compaction construction can be used for many foundation improvements. It can improve the stability of foundation in dynamic compaction construction and enhance the bearing capacity of foundation. The improvement and application of the foundation can be compared. The effect is good, and the change of soil structure layer can be more stable.
