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!

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.

After high-pressure waterjet-assisted drilling, the pile sinking resistance is significantly reduced, the pile sinking speed is accelerated, the efficiency is increased by more than 50%, and the construction cost is not increased. Since the difficulty of pile driving is greatly reduced, the quality of the pile body is effectively protected.

The high-pressure water jet-assisted pile driving construction method has the characteristics of safety, reliability, fast construction speed, low cost, reduced construction noise, energy saving and environmental protection, and the difficulty of pile driving is significantly reduced.

The resistance of pile sinking is reduced, and for hammered piles, the hammering energy will be greatly reduced; for static pressure piles, the working power of static pressure machinery will also be greatly reduced, which is energy-saving and environmentally friendly.

Scope of application

Different solutions can be applied to different soil conditions:

In hard soil, the water jet head can be used to directly drill holes, which has obvious advantages in pile driving;

Clay layer, sand layer, residual soil or fully weathered rock can also be applied. When the geology is fully weathered rock, high-pressure water can be used directly to punch holes;

Not applicable to weathered rock or strongly weathered rock formations.

Significant economic and social benefits

Market demand

Compared with traditional pile foundation construction technology, high-pressure water jet-assisted pile driving technology can save pile foundation project costs, has faster construction speed, safe and reliable quality, meets green and environmental protection requirements, and has huge market demand.

Project quality

High-pressure water jet assists pile driving, which greatly reduces the difficulty of construction and protects the pile body. It has fast construction speed, fewer processes, low project cost, convenient construction, and easy quality control. The on-site construction technology is mature, which reduces project risks.

Working environment and labor intensity

High-pressure water jet-assisted pile driving technology reduces the difficulty of pile driving, hammering energy or static pressure mechanical power is reduced, engineering noise is reduced, construction machinery is reduced, the working environment is improved, construction difficulty is reduced, pile pressing procedures are reduced, and construction speed is accelerated. Conducive to safety, civilized construction and environmental protection.
