有していた。 Currently, the so-called consolidation method, which improves the ground by applying dynamic forces such as vibrations and shocks, is widely used.For example, the sand compaction pile method, which involves driving sand piles into the ground, The vibroflotation method, which involves putting one's body in, and the dynamic consolidation method, which involves dropping a weight, have already been put into practical use. The sand compaction pile construction method is applicable to both sandy and clay soils, and can be constructed on land or offshore, so it is widely used. Construction equipment such as casing pipes is large-scale and requires a large amount of drain (sand), making the construction cost extremely high.Furthermore, the vibroflotation method and dynamic consolidation method are limited to land construction. Furthermore, each method had its advantages and disadvantages, such as the fact that the dynamic consolidation method was only applicable to clayey soil.

いた。 In addition, the vibration and impact loads are used not only for ground improvement but also for leveling surface sediments. For example, a vibrating underwater leveling machine is used to level out a layer of rubble formed on the bottom of a water body. There is a construction method. However, conventional vibrating underwater leveling machines have a configuration in which a tamper is integrated into the vibrator as a leveling weight and is directly vibrated vertically.As a result, the viscous resistance of the water is large due to the vertical vibration, and vibration energy is This results in the loss of a large amount of energy, which causes the inconvenience that a large vibrator must be used accordingly.
