• Concrete sheet piles and piles

The "Kemun Method / ST Kemun Method" is a low-vibration, low-noise construction method that can securely anchor to the supporting layer and adapt to various ground conditions. While excavating and mixing, water or a pile surrounding fixation fluid is injected from the tip of the drilling bit. Once the desired depth is reached, a specified amount of solidification fluid is injected to construct the solidified bulb section. Next, the excavation mixing shaft is pulled up while injecting the pile surrounding fixation fluid. In this way, a pile is inserted into the excavated hole and positioned at the desired location by self-sinking or rotation. 【Features (Common)】 ■ Low noise, low vibration method ■ By rotating the pile, it can be securely anchored to the supporting layer ■ The pile surrounding fixation fluid is injected along the entire length of the pile surface, allowing for expected friction ■ Wide range of applicable ground conditions ■ The solidification fluid contains a leakage prevention agent, resulting in a high-quality expanded solidified bulb section *For more details, please download the PDF or feel free to contact us.

The "STJ Method" is a construction method for precast concrete piles that falls under the category of low-noise and low-vibration methods for the middle excavation and enlarged root solidification. By switching the auger's rotation to a low speed and jetting cement milk from high-pressure injection nozzles in two directions while raising the auger at a constant speed, a reliable enlarged bulb is constructed. 【Features】 ■ Reliable construction of enlarged bulbs ■ High bearing capacity ■ Rapid construction ■ Low construction costs ■ Low earth discharge method *For more details, please download the PDF or feel free to contact us.

The "NS Ecopile(R) Method" involves a technique where a steel pipe pile with spiral blades welded at the tip is rotated using a full-turn machine to excavate the ground and drive it in. The method confirms the reach to the bearing layer for all piles based on the construction torque, ensuring that the penetration into the bearing layer is secured to at least the pile diameter (1Dp) as a principle. Additionally, it does not use water or cement, and no excavation spoil is generated. 【Features】 ■ A soil-free method with high penetration capability using open-ended steel pipe piles with blades. ■ Can be constructed in narrow spaces with compact machinery, allowing for reliable stop management based on construction torque. *For more details, please download the PDF or feel free to contact us.

The "NEW Super FK Method" is a friction support method that enhances the lateral earth pressure and generates greater frictional force by adding the reaction force from the expansion pressure caused by the fixed liquid around the piles, compared to conventional friction pile methods. It allows for various combinations of pile materials to suit ground conditions and applications. Additionally, significant cost reductions can be achieved by shortening the pile length. 【Features】 ■ Top-class frictional force ■ Supports various variations ■ Simple construction that meets the needs of the times *For more details, please download the PDF or feel free to contact us.

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.

• Ground foundation construction method

The "Hyper-NAKS II Method" is classified as an embedded pile method using precast concrete piles, specifically the middle excavation and expansion foundation method. With the hydraulic mechanism, the starting position for wing expansion and the position for fixed liquid injection around the pile can be confirmed in real-time by the construction management device. Additionally, since it allows for the construction of the bulb section in a clockwise direction, it increases the soil discharge rate within the bulb section, enabling the construction of high-quality bulbs. 【Features】 ■ Dramatic increase in bearing capacity ■ Maximum pile diameter is φ1200mm ■ Maximum construction depth exceeds 70m ■ Foundation bulb structure using hydraulic expansion bits ■ Adoption of a new construction management system that ensures workability and reliability *For more details, please download the PDF or feel free to contact us.
