High Pressure Water Jet-assisted Pile Driving Process
High-pressure water jet-assisted pile driving technology is to install a high-pressure water jet at the lower end of the pile during pile driving to spray high-pressure water jets to cut the soil. The jet water flow and pile sinking are synchronized, which solves the problem of difficulty in penetrating hard soil layers during pile driving. Problem, especially for harder soil layers with a standard penetration number greater than 20, the effect is more significant. With the further promotion of the green prefabricated building concept in the development of the construction industry, prefabricated piles such as steel sheet piles, H-shaped steel, and steel pipe piles are increasingly used in underground projects such as deep foundation pits. At present, the traditional vibration method is generally used for pile sinking construction of prefabricated piles. However, this method is more difficult to sink piles in harder soil layers (hard plastic clay, dense sand layers, etc.), progresses slowly, and is extremely inefficient. High-pressure water jet-assisted pile driving technology solves this problem!
