Reinforced earth bridge abutment method
The RRR method (Reinforced Railroad with Rigid Facing-Method) is a new soil retention (reinforced soil wall) technique developed as an alternative to traditional retaining wall methods, using the principles of reinforced soil engineering. Traditional retaining walls are structures that, from a mechanical perspective, aim to support external forces (earth pressure) exerted by the soil through the weight of the structure and the ground reaction of the foundation, opposing the soil and relying on force to counteract force. In contrast, the reinforced soil wall method promotes the stabilization of the soil itself by placing tensile reinforcement materials within the soil, embodying a philosophy of coexistence with the soil.

Additionally, since it does not involve fire, it reduces the risk of fire and burns. 【Features】 ■ Technology suitable for small-scale bridges ■ Can be applied by anyone ■ Applicable to straight butt joints ■ Can also accommodate slide joints and embedded joints (conditions apply) *For more details, please download the PDF or feel free to contact us.
The only company in Japan that can construct using an exterior insulation method that takes advantage of the characteristics of reinforced concrete masonry (RM construction) is ours.
We will build a house with high insulation and heat retention effects, allowing for a cool summer and a warm winter.
A method that improves the working environment and the global environment, while also successfully reducing costs.
The Success Small Method has eliminated the need for heavy labor underground by using a continuous discharge device with a crushing mechanism. Additionally, the continuous soil and sand classification device with a shower has enabled the circulation and reuse of muddy water, significantly reducing the industrial waste discharged outside. Furthermore, continuous operation of the pushing process is possible, resulting in successful total cost reduction. This new method is environmentally friendly for both the working environment and resource environment, and it excels in cost balance.
Connecting urban comfort with people! Demonstrating features in construction at difficult locations where excavation across tracks and other obstacles is challenging.
We would like to introduce the "Advancement Method" that we implement. There are two main types of underground pipe installation work: the open-cut method, which involves excavating the ground, laying prefabricated pipes at the bottom, and then backfilling, and the non-open-cut method, which allows for underground penetration without surface excavation. The advancement method we employ belongs to the non-open-cut category, which results in less surface excavation compared to the open-cut method. This leads to a reduction in the area occupied by construction, a decrease in construction-related nuisances such as noise, vibration, and dust, and minimizes the impact on traffic and community life. [Features] ■ Underground pipe installation work is divided into open-cut and non-open-cut methods. ■ The non-open-cut method involves less surface excavation compared to the open-cut method. ■ There is a reduction in the area occupied by construction, as well as in construction-related nuisances such as noise, vibration, and dust. ■ It excels in construction at locations where open-cutting is difficult, such as crossing tracks. *For more details, please refer to the PDF materials or feel free to contact us.
[Coastal Technology Research Center Certification: No. 14002] Demonstrated 19 years of aging consolidation through large-scale field injection tests!
The "Permanent Grout Injection Method" is one of the chemical injection methods. The purpose of improving this method is for permanent improvement, but in recent years, its application range has also expanded as an injection method for temporary improvement. The injection material used is "Permanent Grout," which has been theoretically and empirically validated for permanence, and the injection form is designed to be a permeation injection method that does not disturb the sedimentary state (framework structure) of the ground, with the principle of uniformly improving the ground. The "Super Multi-Point Injection Method" achieves ideal permeation injection and high workability by injecting at an extremely low discharge rate of 3 liters per nozzle, simultaneously from 32 nozzles per pump. 【Demonstration of 19-Year Long-Term Durability through Large-Scale Field Injection Tests】 The results of large-scale field injection tests combining Permanent Grout (injection material) and injection methods (such as the Super Multi-Point Injection Method) have been evaluated for their permeation solidification and long-term solidification properties, earning the 2002 Technical Development Award from the Japanese Geotechnical Society (Yonekura, Shimada). Confirmation tests have continued even after the large-scale field injection tests, and in 2018, the long-term solidification properties were confirmed 19 years later.
This is a ground improvement method suitable for liquefaction countermeasures, achieved through extensive infiltration and rapid construction of large-volume soil. The consolidation over 19 years has been demonstrated through large-scale outdoor injection tests!
The "Permanent Grout Injection Method" is one of the chemical injection methods. The purpose of improving this method is for permanent improvement, but in recent years, its application range has also expanded as an injection method for temporary improvement. The injection material used is "Permanent Grout," which has been theoretically and empirically validated for permanence, and the injection form is designed to be permeation injection that does not disturb the sedimentary state (skeletal structure) of the ground, with the principle of uniformly improving the ground. The "Expakka Method" involves attaching bag bodies (geo-bags) at intervals to the injection outer pipe, inflating these bag bodies to anchor them in the ground and form soil packers, which enables permeation injection by injecting from a large space, allowing for rapid improvement over a wide area. The Expakka Method series includes Expakka-N Method, Expakka NEO Method, 3D-EX (Expakka) Method, and Expakka Lotus Route Method. [Demonstration of Long-Term Durability Over 19 Years Through Large-Scale Field Injection Tests] The results of demonstration tests on permeation solidification and aging solidification through large-scale field injection tests combining Permanent Grout (injection material) and injection methods (such as the Expakka Method) have been evaluated, and the method received the 2002 Technical Development Award from the Japanese Geotechnical Society (Yonekura, Shimada).
【Cost Reduction for Earthquake Measures】No need for changes to the drawings, low cost, and easy installation! Ideal vibration control dampers for wooden houses for seismic resistance, vibration reduction, and base isolation <Distributors Wanted!>
Are earthquake measures and seismic measures sufficient? The current seismic standards in the building code are designed to withstand seismic intensity of 6 strong or higher, but it is also necessary to consider damage from aftershocks, as seen in the Kumamoto earthquake, where significant damage occurred. In this context, an important option is the addition of "vibration control" alongside seismic measures. The Tokiwa System's α Damper ExII reduces earthquake damage to buildings by about half, effectively mitigating the impact of repeated aftershocks. Additionally, it can be implemented without changes to the design, contributing to cost reduction for seismic measures. **Features** - Can be implemented without changes to the design - Suitable as an alternative to seismic and vibration control devices - Contributes to cost reduction - Improves construction efficiency *For more details, please download the catalog or feel free to contact us.*
