Two-axis coaxial underground steel pipe installation method

The pull-out resistance is extremely strong! Since the soil will return to the steel pipe after installation, soil treatment will require only a small amount.

This technology uses a dual-axis coaxial drilling machine to embed steel pipe piles through an inner excavation foundation pile embedding method. The augers used are formed by an auger that rotates the screw and an auger that rotates the steel pipe. Each type comes in both separate and single models, which are selected based on construction conditions. Additionally, when excavating gravel layers or bedrock layers, a necessary number of ultra-hard pipe bits for the cutting edge are attached to the tip of the steel pipe pile. 【Features】 ■ Extremely strong pull-out resistance ■ Embedding in gravel and bedrock is also possible ■ Vertical accuracy is exceptionally good ■ Soil is returned to the steel pipe after embedding, resulting in minimal soil disposal ■ Construction can be performed with low vibration and low noise *For more details, please refer to the PDF document or feel free to contact us.
