Pre-boring expansion grouting method "Hyper-Straight Method"

A construction method that can accommodate various ground conditions, with high load-bearing capacity and low cost.

The "Hyper-Straight Method" involves pre-drilling the ground with an auger, followed by the injection of solidification liquid and pile surrounding fixation liquid, allowing the pile to be inserted into the designated support layer by self-sinking or rotation, achieving a depth of 1D or more. Using a drilling and mixing device composed of an auger head, screw, mixing rod, and connecting rod, the construction process follows the steps from drilling to the injection of solidification liquid, repeated solidification above and below, injection of pile surrounding fixation liquid, repeated fixation above and below, and finally pile insertion and installation. Additionally, by implementing a construction management system that supports high precision and efficiency, real-time management of the solidification bulb and support layer is conducted to ensure quality. 【Features】 ■ Easy construction management due to full-length straight drilling ■ No need for specialized under-pinning unique to high bearing capacity ■ A mid-bearing capacity method conceived by returning to the origins of precast concrete pile methods *For more details, please download the PDF or feel free to contact us.
