Proposal for improvement technology of embankment materials utilizing construction-generated soil.

Proposal for improvement technology of embankment materials utilizing construction-generated soil.

Significantly contributes to shortening construction periods and reducing costs! We have a track record of over 3 million m³ of construction nationwide.

We will introduce the "Improvement Technology for Embankment Materials Utilizing Construction Excavated Soil." Our company proposes a manufacturing technology for embankment materials through particle size improvement using construction excavated soil, which significantly contributes to shortening construction periods and reducing costs by employing a stabilizer. Additionally, by equipping the stabilizer with GNSS, operators can confirm the construction position and monitor the mixing situation in real-time. Furthermore, since the construction records are digitized, it leads to a reduction in construction management through the output of reports after completion. 【Construction Cycle】 1. Transporting soil and creating the improvement yard 2. Primary mixing 3. Adjustment (after primary mixing) 4. Secondary mixing 5. Transporting improved soil 6. Reusing construction excavated soil as embankment material *For more details, please refer to the PDF document or feel free to contact us.

Reduction of fixed materials, decrease in generated residual soil, and improved mixing efficiency! 'Rising Method'

Reduction of fixed materials, decrease in generated residual soil, and improved mixing efficiency! 'Rising Method'

By using a special mixing agent, the water-to-solid material ratio of cement milk can be concentrated up to 40%, enabling the construction of high-strength improved soil!

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 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 may impede construction," achieving various benefits. 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. It has obtained the Architectural Technical Performance Certification from the Japan Building Disaster Prevention Association. 【Features】 ■ Reliable quality control ■ Enhanced mixing effect with unique technology ■ Applicable to small buildings as well as civil engineering structures ■ Compatible with a wide range of soil types ■ Confirmation of advanced ground ■ Low noise and low vibration *For more details, please refer to the PDF materials or feel free to contact us.

Ground Improvement in Wakayama Prefecture: Ground Reinforcement Method 'Woody Force Method'

Ground Improvement in Wakayama Prefecture: Ground Reinforcement Method 'Woody Force Method'

Applicable to sandy and clayey soil in Wakayama Prefecture! This is an ecological construction method that utilizes small-diameter thinned timber as ground reinforcement material for houses, taking the environment into consideration!

The Woody Force method is a ground reinforcement technique aimed at small-scale buildings, utilizing unused thinned wood. This method uses thin-diameter thinned wood of "sugi" (cedar) or "hinoki" (cypress), which is somewhat too slender for use as house pillars and has been largely underutilized, as ground reinforcement material for houses, making it eco-friendly. By applying anti-corrosion and anti-termite treatment that complies with AQ certification (certification for quality wood building materials, etc.) B-3 (outdoor product components) to the wood used as ground reinforcement material, we aim to further enhance durability. 【Features】 ■ CO2 Reduction - Does not use cement or steel, which emit large amounts of CO2 during the manufacturing process - Contributes to energy conservation and reduction of greenhouse gases ■ Durability - By applying anti-corrosion and anti-termite treatment that complies with AQ certification B-3 to the wood used as ground reinforcement material, we aim to further enhance durability. *For more details, please refer to the PDF document or feel free to contact us.

Ground Improvement Work "Screw Press Method"

Ground Improvement Work "Screw Press Method"

Protecting Japanese buildings from earthquake disasters! Because it's in unseen areas, assurance of seismic and environmental performance is essential.

The "Screw Press Method" is a ground improvement technique that enhances soil bearing capacity, creates earthquake-resistant ground, and is an environmentally friendly low-carbon ground improvement method. The crushed stone columns created by this method compact the entire ground through pressure, and even if shear occurs, it has little effect on strength, while also effectively attenuating seismic waves, protecting your valuable home from earthquakes. It demonstrates tremendous effectiveness in liquefaction countermeasures by strongly compacting the ground and dissipating pore water pressure through highly permeable piles. This method resolves the concerns and worries associated with traditional ground improvement work, creating a reliable foundation to support buildings. 【Features】 ■ Significant reduction in construction time and costs ■ Environmentally friendly low-carbon ground improvement method ■ Capable of forming piles from thinned wood or crushed stone columns ■ Excavation method with zero excavation residual soil ■ Crushed stone columns are strong against earthquakes and significantly reduce liquefaction phenomena *For more details, please refer to the PDF document or feel free to contact us.

Ground Improvement Work "Screw Press Liquefaction Mitigation Method"

Ground Improvement Work "Screw Press Liquefaction Mitigation Method"

Eliminate liquefaction damage from residential land in Japan! Ultra-low-cost liquefaction countermeasure methods.

The "Screw Press Liquefaction Mitigation Method" is a construction method suitable for residential areas, characterized by being vibration-free, low-noise, and having a short construction period. It is a hybrid method that simultaneously compresses sandy ground and dissipates pore water pressure, addressing liquefaction issues while also improving ground stability (increasing bearing capacity). Effectiveness tests were conducted over two years in collaboration with Nagaoka University of Technology at the prefectural land "Manyo Wharf" in Takaoka City, Toyama Prefecture, confirming its significant effectiveness. 【Features】 ■ An environmentally friendly method that does not use cement ■ Also improves ground stability (increases bearing capacity) ■ Vibration-free, low-noise, short construction period ■ Extremely low cost compared to existing methods ■ Generates very little drilling waste *For more details, please refer to the PDF materials or feel free to contact us.

Risks of ground improvement

Risks of ground improvement

There are many pitfalls in easy ground improvement and reinforcement work.

Did you know that in cases of weak ground, despite the ground reinforcement work being done, ground accidents actually occur more frequently than fires? Even if you go through the trouble of ground improvement and reinforcement work, if your house tilts due to differential settlement, it is the same as having a defective house. Because the ground, which cannot be seen, is what truly supports your home, it is essential to choose ground improvement and reinforcement work that genuinely provides support. [Examples of Ground Accidents] - Accidents with slab foundations and surface improvement - Cases where cement does not set properly - Piles not reaching the hard ground - If the thickness of soft ground and hard ground differs, the friction will also differ *For more details, please refer to the PDF materials or external links, or feel free to contact us.
