Principle and advantage of hydrostatic pile driver

Working principle:
Construction process: measurement and positioning → pile driver in place → pile lifting and inserting → pile body aligned with middle injection → static driving pile → pile connecting → static driving pile again → pile feeding → pile pressing termination → acceptance → pile driver handing over.
Function description:
1. Civilized construction -- low noise, no pollution, clean site, low labor intensity.
2. High efficiency of piling - hundreds of meters per shift (8 hours).
3. Good quality of pile - the eight-way design of pile grabber requires low strength of pile, high quality of pile, simple and reliable operation.
4. The fuselage structure adopts modular design, easy to install, disassemble and transport; The maintenance is more simple and convenient, and the cost is lower.
5. Suitable for pile type diversification -- square pile, round pile, H-type steel pile, etc.
6. Intuitive and reliable - through the instrument data of piling construction, it can directly reflect the resistance of piling and predict the bearing capacity of single pile.
7. Equipped with special crane.
Matters needing attention
1. The same pile (section) should be pressed continuously. Pile pressing can be stopped when the gauge reading reaches a predetermined value.
2. Pile driving should check the pressure, pile perpendicularity, pile spacing, pile quality, pile depth. The structures under reaction should be observed more closely.
3. The pressure gauge for the pressure pile must be calibrated before it can be used. The depth of pile and the value of pressure gauge are the basis to judge the quality and bearing capacity of pile, and are also important parameters to guide the construction of pressure pile, which need to be recorded.
Overview of static pile driver
There is no noise, vibration and pollution in the construction process of static pile method, the construction speed is fast, the site is clean, and the construction civilization is high. Low interference to the surrounding environment, suitable for soft soil areas, urban centers or densely populated areas of pile engineering, as well as the expansion of precision factories.
