[Construction Achievements] Sto Dry Spray Method - Tome Road Improvement Project

[Construction Achievements] Sto Dry Spray Method - Tome Road Improvement Project

[Tomoya Road Improvement Project] High-level technology and quality! Nearly 40 years of experience with polymer cement dry spraying method.

The "Sto Dry Spray Application Method" was developed in Germany, a leading country in concrete repair technology, and is a dry spraying method using premixed polymer cement mortar with nearly 40 years of proven performance in Europe. Just before the factory-produced premixed polymer cement mortar, which is composed of cement, aggregates, polymers, and fibers in predetermined ratios, is sprayed, an appropriate amount of water is supplied, and the material is compacted by the impact force of air pressure. This allows for the formation of cement mortar that meets the required performance for cross-section repair materials. 【Features】 ○ Can consistently supply high-quality materials ○ No need for a material stockyard ○ Construction is possible under traffic vibrations ○ Rebound material has very little moisture and is easy to handle ○ No generation of washing water for equipment or packaging dust, allowing for environmental consideration For more details, please contact us or download the catalog.

Bell method

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.

Soil bag method

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"

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

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.
