Description
Technical Field

Background
The territory of China is wide, the soft foundation is widely distributed, and particularly, the three large urban groups of the Jinjin ring Bohai sea, the Yangtze river delta and the Zhujiang delta are particularly notable in a plurality of plain areas where the soft foundation such as saturated silt, silt and fine sand is widely distributed. Under the action of moderate earthquake, the soft foundation can cause liquefaction earthquake subsidence and foundation bearing capacity loss, which can cause additional settlement of the foundation and soil layers, overturning, tilting, cracking, sliding and the like of the structure and the foundation, and can cause that various infrastructures and buildings can not normally operate, and the functions are partially and even completely lost.
Soft foundation liquefaction causes great damage to the building during an earthquake, but in actual engineering, the phenomenon of sand liquefaction can be utilized. Recently, vibration grouting has become a new construction method for treating soft foundations. The basic principle of the vibration grouting technology is to force the saturated fine sand and silt foundation to liquefy by adopting a mechanical vibration method so as to lose strength, and then to pour slurry into the foundation. The method comprises the steps of firstly forming a softening area in a sandy soil foundation through impact vibration of a vibration machine tool, and then pressing slurry into sandy soil by using a grouting pipe.
Since the liquefaction effect of soft foundation sand becomes obvious with the increase of the vibration frequency, particularly when the vibration load operating frequency is close to the natural frequency of sand, the liquefaction effect is most obvious because of the resonance effect. However, the prior art can only apply vibration on the top of the drill rod, the vibration is difficult to be transmitted to the end of the drill rod, the frequency of the conventional common vibrator is almost no more than 150HZ, but the natural frequency of sand can reach 800HZ, and the vibration frequency of the conventional pneumatic vibrator is low.
