The high-pressure water jet drilling and extraction equipment for steel sheet piles is an efficient device that uses high-pressure water jets to impact the soil to form drilling channels and assist in the sinking and extraction of steel sheet piles.
1、 Protecting the pile and equipment: High pressure water jet pre disperses the soil, reduces the lateral friction resistance and end resistance of the pile, avoids the bending, tilting or cracking of the pile caused by traditional hard driving, reduces the load on the driving equipment, extends the service life of the pile and machinery, especially suitable for leasing steel sheet pile projects.
2、 Efficient adaptation to complex geological formations: In dense sand layers, clay layers, and gravel containing formations, the efficiency of borehole drilling is much higher than that of manual or ordinary machinery, and can be carried out in a flow process with pile sinking and extraction procedures, resulting in an overall progress improvement of 30% -50%; Low vibration and noise, suitable for construction in densely populated urban areas and around sensitive buildings.
3、 Flexible operation and controllable cost: The equipment has a high degree of integration, and only 1-2 people can operate it. Compared with large special drilling rigs, the initial investment and operation costs are lower, and the long-term cost can be recovered by reducing pile damage and shortening the construction period.
4、 Outstanding pile removal effect: The soil around the jet pile loosens the bond between the pile and soil, significantly reducing the resistance to pile removal and minimizing pile damage. It is especially suitable for removing old piles or steel sheet piles with large burial depths.
