The "Alpha Force Pile Method" requires minimal equipment to be brought to the site and generates no residual soil, thus preventing complicated processes and providing a clean and safe working environment with rotary embedded steel pipe piles. By making the wing section uniform in width and smoothly spiraled, it ensures that large bending stresses do not concentrate in specific areas, thereby securing the overall load-bearing capacity of the wing section. Additionally, a single wing design is adopted to avoid disturbing the surrounding ground during rotary penetration. 【Features】 ■ High strength and construction quality ■ High processing precision *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

The "Alpha Force Pile Method II" is a construction method that integrates wings in a spiral shape at the tip of a copper pipe, allowing it to be rotated and driven into the ground for use as a pile. By having the tip wings also serve as a closure cap, it achieves improved processing accuracy and cost reduction. Additionally, it adopts a unique shape that enhances the pile's bearing capacity while suppressing ground disturbance caused by the rotational driving, enabling excellent penetration performance. We have also prepared a rich lineup that can accommodate a wide variety of building and ground conditions. 【Features】 ■ Removable ■ Compact foundation ■ No cement used ■ No need for soil disposal ■ No curing period required *For more details, please refer to the PDF document or feel free to contact us.

• Ground foundation construction method

The "Fine Pile Method Civ" is a construction technology that forms an improved body in the ground using a completely different mixing technology from conventional methods, ensuring stable strength and homogeneity, and has obtained construction technology review certification. It employs mechanical mixing technology that cuts soil clumps and clay using anti-rotation wings, along with chemical mixing technology that reduces the viscosity of soil-cement slurry. It can be constructed with an improvement diameter of φ1500mm and an improvement length of up to 18m, making it applicable to a wide range of small to medium-sized buildings, while reducing variability in strength development. 【Features】 ■ Improvement diameter and length suitable for medium-sized buildings and structures ■ Ability to reduce variability in strength development ■ Improved fluidity of soil-cement slurry and cement slurry ■ Safe as it primarily consists of substances designated as food additives ■ Does not affect strength or shrinkage rate after solidification *For more details, please refer to the PDF materials or feel free to contact us.

There are "precast concrete piles," which are manufactured in factories and then driven into the ground, and "cast-in-place concrete piles," which are created by pouring concrete into holes excavated in the ground. Cast-in-place concrete piles involve dropping a cylindrical rebar structure assembled on-site into the excavated ground, and then pouring concrete into the hole to form a pile shape. Concrete piles include "bearing piles," which are driven to the bearing layer, and "friction piles," which are driven to stable ground.

Our company conducts "ground surveys" to understand the properties of the ground necessary for constructing structures. Based on the survey results, we appropriately determine whether ground reinforcement is needed. We perform various tests, including the "Standard Penetration Test" mainly used for general buildings, the "Swedish Sounding Test" used for single-family homes, and the "Ram Sounding Test" used for single-family homes in areas with deep bearing layers, as well as various load tests. 【Details】 ■ Standard Penetration Test ■ Swedish Sounding Test ■ Ram Sounding Test ■ Other various load tests *For more details, please refer to the related links or feel free to contact us.

• Site and ground investigation

"Ground improvement" involves artificially enhancing the properties of the ground or soil. The targets for improvement include weak clayey or sandy ground, unstable rock formations, and permeable rock formations. In "columnar improvement," cement-based solidifying materials are injected to a stable ground level, creating columnar bodies within the soil. In "surface improvement," cement-based solidifying materials are spread over relatively shallow weak ground, and the strength of the ground is increased through mixing, stirring, and compaction. 【Details】 ■ Columnar Improvement ■ Surface Improvement *For more information, please refer to the PDF document or feel free to contact us.

We would like to introduce our construction technology "Special Boring and Pre-Excavation." Special Boring is a suitable method for excavation when encountering bedrock or similar materials during the installation of various types of piles. It allows for bedrock excavation, rebar concrete core drilling, and horizontal boring for landslide countermeasures. Additionally, Pre-Excavation is a construction method that is originally intended to be done without excavation, but is performed to facilitate progress when excavation cannot proceed smoothly. [Overview] ■ Special Boring: Bedrock excavation and horizontal boring for landslide countermeasures, etc. ■ Pre-Excavation: Conducted when encountering various piles, obstacles, or hard intermediate layers. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our construction technology, "Steel Pipe Piles." These steel piles have significant vertical and horizontal load-bearing capacity, making them suitable for foundations of buildings and for landslide prevention. We mainly offer "Straight Piles," which are often used for sound barriers, and the "Alpha Force Pile Series." [Types] ■ Alpha Force Pile Series ■ Straight Piles *For more details, please refer to the related links or feel free to contact us.

• Piles, caissons, sheet piles

"Sheet piles" are steel plates with irregularities and joints at both ends. When combined alternately and connected at the joints, they create a "wall of iron," which can be embedded in the ground to construct embankments, breakwaters, and quay walls. After use, they can be repeatedly utilized by pulling them out. Please feel free to contact us if you have any requests. 【Related Methods】 ■ Vibro Method ■ Pre-boring Combined Press-in Method ■ Rock Auger Combined Method ■ Press-in Method *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our construction technology "H Steel." It has a cross-section shaped like an "H" and is one of the most representative types of shape steel. Compared to other shape steels, it has superior cross-sectional efficiency (bending stiffness and bending strength per weight) and is mainly used as a retaining pile in civil engineering and construction. Please feel free to contact us if you have any requests. 【Related Methods】 ■ Cement Milk Method ■ Pre-Boring Combined Impact Method ■ Impact Method ■ Vibro Method *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our construction technology "Wood Piles." While wood piles may have a reputation for being more susceptible to decay compared to metal or stone, wood-decaying fungi are aerobic, and when used properly, wood can demonstrate sufficient durability. Our company handles materials such as pine piles.
