Ground Improvement Method "Rising Method"

Ground Improvement Method "Rising Method"

Constructing highly homogeneous block-shaped improved bodies! A ground improvement method that realizes a solid foundation for buildings.

The "Rising Method" is a ground improvement technique that involves placing pre-excavated soil into the excavation area and using a uniquely developed mixing bucket to mix the soil with slurry (W method) or soil with solidifying agents (D method), thereby constructing a homogeneous block-like improved body. By excavating the soil in advance, it allows for the "confirmation of the support layer and the soil to be improved," and also enables the "removal of organic soil that hinders solidification, as well as gravel layers, boulders, industrial waste, and underground obstacles that may obstruct construction," achieving several advantages. Additionally, in the W method, as a quality control test immediately after construction, the resistivity of the improved body is measured to confirm the mixing conditions. 【Features】 ■ Reliable quality control ■ Enhanced mixing effects with proprietary technology ■ Applicable to small buildings as well as civil engineering structures ■ Compatible with a wide range of soil types ■ Confirmation of advanced ground conditions ■ Low noise and low vibration *For more details, please refer to the PDF document or feel free to contact us.

Ground reinforcement method "Economic Base Method"

Ground reinforcement method "Economic Base Method"

An ecological and economical ground reinforcement method that supports with a surface using reinforced bodies made of crushed stone!

The "Economic Base Method" uses a uniquely developed casing to excavate soft ground and fills the excavation hole with compacted crushed stone, thereby constructing a columnar crushed stone reinforcement body. This reinforcement body is utilized in combination with the bearing capacity of the original ground as a ground reinforcement method. This method can be adapted to various construction machinery depending on the site, and using a pile driver allows for construction even in narrow spaces or adjacent to narrow roads. Additionally, the crushed stone made from natural stone maintains stable quality and protects the ground over a long period. 【Features】 ■ Crushed stone does not deteriorate ■ Usable in narrow spaces ■ Stable construction with casing ■ Provides safety by supporting with a surface rather than a point ■ Environmentally friendly due to minimal soil displacement *For more details, please refer to the PDF materials or feel free to contact us.

The ground improvement method "Rising Method" that achieves a solid foundation for buildings.

The ground improvement method "Rising Method" that achieves a solid foundation for buildings.

"From small-scale buildings to civil engineering structures" is a ground improvement method that mixes soil and slurry or solidifying agents to construct a highly homogeneous block-like improved body.

The "Rising Method" is a ground improvement technique that involves placing pre-excavated soil into the excavation area and mixing it with slurry using a uniquely developed mixing bucket to create a highly homogeneous block-like improved body. By excavating the soil in advance, it allows for the "confirmation of the supporting layer and the soil to be improved," and also enables the "removal of organic soil that hinders solidification, as well as gravel layers, boulders, industrial waste, and underground obstacles that can impede construction," thus achieving various benefits. ★ It has obtained the Architectural Technology Performance Certification from the Japan Building Disaster Prevention Association. Additionally, it has a record of NETIS registration SK-130021A (registration period has ended). 【Are you facing any of these issues in ground improvement methods?】 ■ Unable to confirm the supporting layer… ■ Unable to manage the quality of the improved body… ■ Unable to remove underground obstacles… ■ Excavation loss due to circular shape construction… ⇒ We will solve all these concerns! * There is also the "Ultra Column Method," which can reduce poor mixing caused by the phenomenon of soil co-rotation that is problematic in low-viscosity ground. * For more details, please refer to the PDF document or feel free to contact us.

[Reason for Adoption] Ultra Wood Column Method

[Reason for Adoption] Ultra Wood Column Method

Stable supply with no price fluctuations! Can be accommodated at depths of soft ground. Construction with compact machinery.

We will introduce the reasons why the "Ultra Wood Column Method" is adopted. Methods such as column improvement and steel pipe pile methods require a supporting layer or stable layer, but this method can be applied at the depth of soft ground. Additionally, it can be implemented up to a maximum of 4.5 meters, specifically addressing soft ground, so there is no need for large, high-power machinery; compact machines like pile drivers can be used. Due to these characteristics, it is adopted in cases such as: "I was told by a ground reinforcement construction company that 'reinforcement work cannot be designed because there is no supporting layer.'" "I was told that the cost of reinforcement work with steel pipe piles is high because the supporting layer is deep." "I was told that I need to implement column improvement for 8 meters in the intermediate layer of the ground." 【Features】 ■ Can be designed for soft ground ■ Construction with small machinery ■ Low raw material costs ■ Reliable because it is a construction method with certified building technology performance *For more details, please refer to the PDF materials or feel free to contact us.

Soil Cement Column Method "Ultra Wood Column Method"

Soil Cement Column Method "Ultra Wood Column Method"

Even a small diameter provides great support! A mechanical mixing deep mixing method that combines the advantages of columnar improvement methods and piles.

The "Ultra Wood Column Method" is a mechanical mixing deep mixing treatment method that constructs columnar ground improvement bodies by excavating and mixing the ground while discharging a slurry of cement-based solidifying material. It was developed to eliminate the shortcomings of both conventional columnar improvement methods and wooden pile methods, while enhancing their advantages. This method combines the benefits of columnar improvement methods, which can provide expected frictional force, and the advantages of wooden piles, which offer stable quality due to being prefabricated. Therefore, even with a small diameter and short improvement length, it is possible to achieve significant bearing capacity. Additionally, this has been proven by numerous experimental results. 【Features】 - Constructs reliable ground for small-scale buildings - Achieves large bearing capacity even with a smaller diameter than conventional columnar improvement bodies - Ensures quality control and construction management - Can be adapted to narrow sites - High mixing efficiency allows for construction in a short period For more details, please contact us or download the catalog.

Ground reinforcement method "Ultra Pillar Method"

Ground reinforcement method "Ultra Pillar Method"

With a uniquely shaped excavation device, you can construct high-quality and stable reinforcement structures!

The "Ultra Pillar Method" is a ground reinforcement method that uses cement milk pile-like ground reinforcement bodies. Since the original ground and cement milk are not mixed, a more stable quality reinforcement body can be constructed compared to columnar improvement methods, leading to improved construction efficiency. By using a uniquely shaped excavation device, the excavated soil moved from the upper and lower augers is pressed against the hole wall protection mechanism to stabilize the hole wall, resulting in minimal residual soil. 【Features】 ■ No mixing of the original ground and cement milk ■ Stable quality reinforcement bodies can be constructed, improving construction efficiency ■ Uses a uniquely shaped excavation device with inverted auger inclination ■ Minimal soil discharge ■ GBRC performance certification No. 18-20 *For more details, please refer to the PDF materials or feel free to contact us.
