It is also used in construction to protect cities from flooding caused by guerrilla rainstorms! It is utilized in the construction of vertical shafts for access tunnels.
The "Large Diameter Deep Depth Steel Pipe Installation Method (φ3200)" is a method for directly rotating and installing steel pipe piles equipped with a drilling bit at the tip. It utilizes a full-circle rotary drilling machine with one of the largest diameters in the country, φ3200mm, capable of handling various underground construction projects. If necessary, large-diameter steel pipes can be directly rotated and installed into bedrock layers. The new technology of casing inner drilling allows for low-noise and low-vibration construction driven by hydraulic power, making it suitable for nighttime work in urban areas. 【Features】 - A method for directly rotating and installing steel pipe piles equipped with a drilling bit at the tip. - Utilizes a full-circle rotary drilling machine with one of the largest diameters in the country, φ3200mm, capable of handling various underground construction projects. - Large-diameter steel pipes can be directly rotated and installed into bedrock layers if necessary. - Effective in construction projects that protect cities from flooding caused by sudden heavy rains. - Can also be used for the construction of launch and arrival shafts for various shield projects. *For more details, please refer to the PDF materials or feel free to contact us.
