The "Kanbee Method" is a technique that utilizes a steel pipe with a welded tip that has excavation claws and holes, which is rotated and driven into the ground for use as a pile-like ground reinforcement material. The characteristics of the tip used in this method include having the same outer diameter as the steel pipe, possessing a tip cone and excavation claws, and having two holes. Additionally, a feature of the construction management is the confirmation of bearing capacity through impact loading tests after the driving is completed. 【Features】 ■ Uses a straight steel pipe with a tip that has holes ■ Economical ■ Short construction period ■ High quality ■ High bearing capacity *For more details, please refer to the PDF document or feel free to contact us.

The "Kanbee Raft Method" is a technique that involves the rotational insertion and burial of a pile-like ground reinforcement material (hereinafter referred to as "reinforcement material") which has excavation claws and a tip fitting welded to the end of a steel pipe. This method utilizes the combined support capacity of the reinforcement material and the underlying foundation soil. By making the tip fitting the same outer diameter as the steel pipe, it is possible to effectively obtain the support capacity of the underlying foundation soil and the lateral resistance of the reinforcement material without disturbing the surrounding soil. 【Features】 ■ Considers the support capacity of both the underlying foundation soil and the ground reinforcement material ■ Economical ■ Short construction period ■ High quality ■ High support capacity *For more details, please refer to the PDF document or feel free to contact us.

"Σ-i (Sigma-I)" is a pile-type ground reinforcement method that involves inserting a pile equipped with four cutting blades and spiral wings into the ground while rotating it. This method consolidates various elements necessary for ground reinforcement, including high pile performance, reliability and safety in construction, and consideration for the environment and neighboring areas. Furthermore, by improving the structure of the tip wings, it has successfully achieved a balance between pile performance and cost reduction. 【Features】 ■ Reliable bearing capacity ■ Development of a new type of tip wing ■ Consistent management system ■ Consideration for the environment ■ Compatible with various ground conditions *For more details, please refer to the PDF document or feel free to contact us.

The "RES-P Method" is a type of piled raft foundation method that strengthens weak ground by driving pipes (thin steel tubes) into the ground, utilizing the combined effect of the ground and the pipes to prevent settlement, serving as a foundation reinforcement method for residential buildings. To support the load of the building, the number, position, and penetration depth of the pipes driven into the ground are determined and designed according to the condition of the ground. As of August 2011, the maximum length of the pipes has been extended from 7m to 14m, allowing for application in deeper soft ground. This method is applicable to buildings with up to three stories, a total floor area of 1,500m2 or less, and a long-term ground pressure of 50kN/m2 or less. 【Features】 ■ Strengthens weak ground ■ Can be constructed to a depth of 14m ■ Planar ground reinforcement method ■ Low vibration and low noise during construction *For more details, please refer to the PDF materials or feel free to contact us.

The "Shinbi Method" is a ground reinforcement technique that constructs soil cement columns by excavating and mixing the ground while discharging a slurry of cement-based solidifying material, and utilizes a thin-walled steel pipe with joints embedded at the center as a ground reinforcement body. The excavation and mixing device of this method is equipped with multiple vertical protrusions on the anti-rotation wings and the upper and lower mixing wings to enhance the mixing performance of the cement-based solidifying material slurry and the ground. By using this excavation and mixing device, it enables construction at low axial rotation speeds and high velocities, while significantly improving the quality of the modified body. 【Features】 ■ Low cost ■ Reduced residual soil ■ High strength ■ High bearing capacity *For more details, please refer to the PDF document or feel free to contact us.

The "SMD Pile Method" is a construction method that involves rotating a steel pipe pile with spiral wings (outer wings) attached to the outer circumference of the pile tip, approximately 2 to 3 times the diameter of the pile, in a right-hand rotation for penetration. The interior of the pile tip is open-ended, and a spiral wing (inner wing) is attached inside the steel pipe, creating a structure that achieves support capacity nearly equivalent to that of a completely closed system. Additionally, this method allows for construction with low noise and low vibration, making it an environmentally friendly technique that does not generate excavated soil or muddy water. 【Features】 ■ High Quality ■ Low Cost ■ Ecology *For more details, please refer to the PDF materials or feel free to contact us.

The "Cross-Wing Column Method" is a slurry-based mechanical mixing deep mixing treatment method that achieves stable mixing performance with minimal variation, unaffected by soil conditions, through a jointly developed excavation mixer. With proven quality backed by numerous experimental results, it is adaptable for various applications such as buildings, retaining walls, and other structures. This method has a small quality control surcharge coefficient, which helps to reduce excessive material usage. Additionally, by adopting Inspection Method A, quality inspections can be conducted at minimal cost. Furthermore, appropriate selection of the improved diameter can lead to shortened construction periods and cost reductions. 【Features】 ■ High Quality ■ Adaptability ■ Low Cost *For more details, please refer to the PDF document or feel free to contact us.
