The "DIA-WIN Method" is a total system from design to construction, incorporating functions such as seismic walls, composite walls (continuous walls + post-installed walls), two-way slab lateral pressure walls, and wall piles, applicable to a wide range of uses from temporary to permanent structures, including deep and thick walls of up to 150 meters. It is a Nishimatsu-style continuous wall method. The joints between the walls have a simple shape, making them easy to clean and providing excellent concrete fillability. Additionally, the use of H-shaped steel materials enhances water-tightness. 【Features】 ■ Excellent cost-effectiveness ■ Applicable to any type of ground ■ Constructs high-quality wall bodies ■ Simple and water-tight joint shape *For more details, please download the PDF or contact us.

• Civil Engineering Method

The "MOVE HAT Demolition Method" is a technique used for the demolition of high-rise buildings in urban areas, where scaffolding is not installed around the building's perimeter. Instead, only the floors being demolished are covered with the elevating protective frame "MOVE HAT," allowing for a sequential demolition from the top floor downwards using static methods such as cutting and removal. By covering the demolition floor with "MOVE HAT," vibrations and noise to the outside are reduced. Rather than crushing the structural framework with large breakers or concrete crushers, it is cut into block shapes using concrete cutters, making waste separation easier. 【Features】 ■ Reduction of vibrations and noise ■ Promotion of waste recycling ■ No need for large cranes, resulting in good workability ■ Reduction of temporary materials and high-altitude work *For more details, please download the PDF or contact us.

• Dismantling and moving

The "NS Beam Method" is a construction technique that consists of placing concrete with the same strength as the floor slab on the upper part of the beam. This method reduces the materials needed for the stop formwork and the labor required to install the stop formwork, thereby streamlining and saving labor in the construction process. Beams manufactured according to the design and construction guidelines of this method do not experience any impairments during the service limit state or damage that compromises repairability during the damage limit state. Additionally, it has been confirmed and proven through structural performance testing that this method possesses the ultimate strength and deformation performance defined by the guidelines at the safety limit state. This method has obtained a building technology performance certification from the Japan Building Disaster Prevention Association. *For more details, please download the PDF or contact us.*

• Civil Engineering Method

The "RCS construction method" features a structural form where the columns are made of reinforced concrete and the beams are made of steel, specifically a column-RC beam-S structure. The column-beam joint section can adopt two types of details, "shear reinforcement type" and "closure plate type," considering stress transmission, making it a construction method that allows for these options. It enables the combination of the two types of details for the column-beam joint, allowing for a design aspect where the joint can be made flush with the concrete surface, similar to the shear reinforcement type. Additionally, by allowing concrete strength up to 60 N/mm², it can be sufficiently applied to large-scale buildings. 【Features】 ■ Capable of using high-strength materials ■ Joint shapes can be selected ■ Effective for buildings with large spaces ■ Expected to be a cost-reducing construction method *For more details, please download the PDF or contact us.

• Wood panel and frame wall construction

The "oil damper-equipped elastic sliding bearing" is a seismic isolation device that enables the suppression of micro-vibrations without the disadvantage of increased costs. The small oil damper installed in the seismic isolation device exhibits damping force during minor deformations caused by micro-vibrations, while during major earthquakes, it is configured to provide seismic isolation effects through the sliding bearing. 【Features】 ■ Compact device ■ Ensures seismic performance against major earthquakes ■ Cost-effective device ■ Also effective in improving livability *For more details, please download the PDF or contact us.

• Earthquake-resistant construction method

This technology is a tunneling support system that enables real-time management of tunnel excavation shape and quantitative evaluation of ground conditions during excavation using a free-section excavator. In this system, the position and posture of the excavator are monitored using a high-speed 3D scanner installed on the machine, allowing for the real-time visualization of excavation position information (the position of the cutter tip) while simultaneously quantitatively evaluating the characteristics of the excavated ground based on the amount of electrical energy consumed during excavation. As a result, it becomes possible to grasp the tunnel excavation shape and the stability of the ground in real-time during excavation work, thereby improving the efficiency and safety of the excavation operations. 【Features】 ■ Measurement of machine position and posture using a high-speed 3D scanner ■ Improvement of excavation efficiency and safety ■ Three-dimensional quantitative evaluation of the excavated ground ■ Real-time monitoring from remote locations ■ Integration with CIM *For more details, please download the PDF or contact us.

• Civil Engineering Method

The "Soil Pressure Type Parent-Child Shield Method" is a construction method that allows for the continuous construction of tunnels with varying cross-sectional diameters using a single shield within the shield excavation extension. A smaller child shield is incorporated within the parent shield to excavate the parent cross-section tunnel. At a designated position, the child shield is separated and launched underground from the parent shield to construct the child cross-section tunnel. By sliding the rear body of the child shield forward to incorporate it and adopting a method where the rear body is pushed out by the shield jack during assembly, the separation and launch can be completed in a short period. 【Features】 ■ The underground separation method eliminates the need for the installation costs of shafts and securing land at the position of cross-section changes. ■ The rear body push-out method significantly simplifies the assembly work of the child shield. ■ During the separation and launch operations, the front body remains fixed to the parent shield with a reaction pin, maintaining the stability of the face. *For more details, please download the PDF or contact us.

The "Composite Shield Method" is a shield that has a mechanism allowing for the selection of the face stability method according to the conditions of the ground. With a single shield, for ground conditions suitable for earth pressure type shields, stability of the face can be achieved using plastic fluidized excavated soil within the chamber, and for ground conditions suitable for slurry type shields, stability of the face can be achieved using slurry, making it a shield with a wide range of adaptability to ground conditions. 【Features】 ■ A single shield can select a face stability mechanism that corresponds to the soil conditions. ■ In gravel ground, gravel can be directly crushed by a crusher, enabling fluid transport. *For more details, please download the PDF or contact us.

• Civil Engineering Method

The "Branch Shield Method" is a shield construction technique that simultaneously constructs two intersecting tunnels in a T-shape using a main line shield and a branch shield that launches laterally from within the main line shield. By launching the branch shield directly from within the main line shield, the need for an intermediate shaft is eliminated, and the setting of the branching position is not affected by surface conditions or the presence of buried objects above the pipeline. 【Features】 ■ The main tunnel and branch tunnel can be constructed simultaneously. ■ The branching position is not affected by conditions near the surface. ■ Ground improvement at the branch shield launch point is not required. ■ Shortened construction period and reduced costs. ■ The ratio of the outer diameter of the main tunnel to the outer diameter of the branch tunnel (approximately 60-65% of the outer diameter of the main shield is a guideline). *For more details, please download the PDF or contact us.
