The pile driver is a kind of pile driver equipment that is often used in construction projects. It uses the effect of high frequency vibration to make the pile driver generate a high vibration force, and then transmits it to the pile body for vertical force. piling. During the piling process, due to the large vibration force, the soil layer structure around the pile body is gradually loosened. At this time, the strength of the soil layer becomes the lowest, which also promotes that the pile body will not be stuck. situation, enter directly. When encountering a high-strength rock layer during the vibration process, we need to drive slowly, so is there any way we can solve this problem?

We can use the vertical action of the mechanical arm to compress the pile body or raise the pile body by about 0.5-1.1m, and then use the vertical force to quickly drive the pile down in a short time. For the vibration of the pile driver, we need to conduct a comprehensive evaluation according to the local environment and the results of the soil to select the appropriate vibration force for piling. Generally, the 100-400 kN vibration method is used to drive piles with high efficiency. Generally, it is suitable for U-shaped steel sheet piles within 10M, I-shaped steel sheet piles, steel pipe piles and cement piles made of cement. This piling method is most suitable for sandy work, and is less effective for clay work. At this time, if necessary, we choose a machine with higher power. The vibration method piling procedure is as follows: lifting the pile body, then determining the verticality, and finally driving the pile accurately. The seemingly simple three steps are actually quite high in technology.
