Ace Sand Method

Fluidize the excavated soil on-site. Please use it widely for backfill materials, filling materials, embankment materials, etc.

The "Ace Sand Method" is a revolutionary technique that pumps backfill materials such as mountain sand into areas where backfilling is difficult. It allows for the recycling of construction by-products (on-site generated soil). This simple and compact plant is capable of handling small-scale projects, while also having a large construction capacity that shortens construction periods and does not restrict the timing of backfilling. Please feel free to use it widely for backfill materials, filling materials, embankment materials, etc. 【Features】 ■ Pumps backfill materials such as mountain sand into areas where backfilling is difficult ■ Good fluidity allows for filling into every corner and can accommodate complex terrains ■ Effective for preventing consolidation settlement and liquefaction ■ Reduces cement usage and improves the utilization rate of generated soil ■ Easily suppresses bleeding by incorporating a small amount of air bubbles *For more details, please refer to the PDF materials or feel free to contact us.

New construction work - Sliding method (Sliding/Slip form method)

Shortened construction period! This is a method that raises the work floor along with the jack.

The slide construction method involves attaching formwork and internal and external working platforms to a frame made of steel (such as H-beams) called a yoke, and then using jacks to raise the working platforms along with steel rods embedded in concrete as reaction forces. The working platforms are constructed in three tiers—upper, middle, and lower—according to the work requirements, with rebar reinforcement, concrete pouring, and plaster finishing both inside and outside. Additionally, if the roof of structures like silos is made of steel, connecting the steel parts to the yoke and raising them simultaneously makes it easier to maintain verticality and roundness, eliminates the need for steel frame erection, and enhances safety. **Features** - The biggest feature of the slide construction method is the reduction of construction time. - Concrete pouring can be done daily after the assembly of the equipment is completed. - It is ideal for super-tall chimneys (H=100-200m) and sites with no construction time constraints. - Continuous concrete pouring minimizes joints. - It is also beneficial in terms of quality.

Achieving a solid foundation for buildings: "Rising W Method ECO"

Eco-friendly with quality improvement and reduced environmental impact through the addition of rising liquid! Low noise and low vibration, gentle on the environment, and suitable for civil engineering structures.

The "Rising W Method ECO" is based on the proven technology of the "Rising W Method" and utilizes a special admixture (Rising Liquid) to achieve a high concentration of cement milk with a water-to-solid ratio of up to 40%. This allows for the construction of high-strength, low-excavation improvement bodies. By reducing the water-to-cement (W/C) ratio, strength increases while the amount of solidifying agent decreases. Additionally, the reduction in injection volume due to the lower W/C ratio leads to less generated excavation soil, and the improved fluidity of the slurry contributes to eco-friendliness. 【Specifications and Application Range (Partial)】 ■ Improvement Type: Block Type ■ Applicable Structures: Buildings, retaining walls, works, and civil engineering structures ■ Mixing Buckets - Skeleton Mixing Bucket Type A, B (sandy soil) - Rotary Mixing Bucket Type A, B (sandy soil, clayey soil, loam) ■ Solidifying Agents: Cement-based solidifying agents, ordinary Portland cement, blast furnace cement Type B ■ NETIS Registration Number: SK-130021-A *For more details, please refer to the PDF document or feel free to contact us.

Bell method

"PVC Pipe Long-Distance Curved Pushing Method" - The world's first pushing technology that contributes to reducing life cycle costs.

The Bell method is a "world-first system" that significantly reduces maintenance costs for sewer pipes and contributes to their longevity. 【Features】 1. Long-distance thrust Unlike conventional methods, the allowable thrust length is not limited by the pipe's allowable load capacity, allowing for long-distance thrust of up to 250 meters even with low-load capacity pipes. 2. Curved thrust The tunneling machine is equipped with two directional correction devices, enabling multiple curved thrusts of up to 60R. 3. Response to obstacles If unexpected obstacles are encountered during tunneling, it is possible to retreat and proceed with a detour alignment. 4. Shortened construction period By adopting an autonomous measurement robot for in-pipe surveying, there is no decrease in daily progress due to the number of curves or curvature radius. Additionally, using the Bell method thrust pipe (1.33m pipe) reduces setup changes by 33% compared to 1m pipes, enhancing work efficiency. 5. Longevity Long-distance and curved thrust is achieved with durable and earthquake-resistant PVC pipes, contributing to the longevity of sewer pipes. 6. Earthquake resistance High earthquake-resistant SUS color is used. The joint section of the thrust pipe maintains water tightness up to an angle of 3 degrees, preventing water and soil from entering. For more details, please feel free to contact us.

Soil bag method

NETIS registration! An environmentally friendly construction method that does not use any solidifying agents.

The "Soil Bag Method" is an environmentally friendly foundation reinforcement technique that does not use any solidifying materials, including cement, by utilizing the "D·Box." The "D·Box" generates significant friction between soil particles, providing various effects such as ground reinforcement, vibration reduction, and liquefaction countermeasures. In particular, it can compact itself regardless of ground reaction, allowing for reinforcement effects even in extremely soft ground such as marshes, which are typically considered difficult. 【Features】 ■ The D·Box is completely permeable to water, so it does not affect the underground environment when installed in the soil. ■ Since the D·Box essentially just encapsulates soil particles, it can reduce CO2 emissions. ■ It has effects equivalent to surface improvement, allowing for efficient ground reinforcement construction. ■ It simultaneously achieves ground reinforcement and vibration reduction, offering excellent cost-effectiveness. ■ It can increase the strength of the surrounding ground where the D·Box is installed. For more details, please feel free to contact us.

Construction Case Study: "Building Construction"

"Total support from the ground to the building" We are showcasing examples of construction work.

In recent years, Japan has experienced natural disasters that can destroy everyday life, starting with the Great East Japan Earthquake. Each time a disaster occurs, it has become an era where everyone feels anxious, wondering, "Is my home okay?" or "Is my workplace okay?" In light of this, our company has seriously discussed how we can contribute to society with technology specialized in ground stability. We have established a new "Construction Department" and are launching a new business that leverages our experience and achievements in specialized civil engineering work. We will create a safer and more secure living environment for our customers, not only through new construction, renovations, repairs, and maintenance, but also by implementing energy-saving measures and addressing foundation and underground issues.

Low-altitude slide construction method

It is a full casing (full rotary) method that enables work up to a depth of 4.4 meters.

We have made it possible to carry out construction that was previously impossible. - Foundation work inside the gymnasium: Previously, part of the wall had to be demolished to bring in machinery, but it is now possible to bring in equipment without altering the current state. - Foundation work along the railway: Work that requires crane booms to extend higher than the tracks is typically done at night, but since we do not use cranes, daytime work is possible. - Bridge widening and under-beam work: Heavy machinery can access the existing under-beam area, allowing vehicles to continue using the existing bridge during construction. - Work under high-voltage power lines: Construction under high-voltage power lines is also feasible.
