Shinbee method

Shinbee method

Ground improvement method using soil-cement columns with thin-walled steel pipes.

■ Performance-Proven Construction Method Building Technology Performance Certification GBRC Performance Certification No. 13-04 Rev. 2 This method has been reviewed by a third-party organization, which certifies the performance of the technology. ■ High Load-Bearing Capacity and High Strength This method combines the benefits of steel pipes with stable quality and strength of columnar improvement bodies. ■ High-Quality Mixing The specialized mixer, equipped with a comb section and eight blades, provides high-quality mixing. ■ Wide Range of Soil Types This method can accommodate a wider range of soil types than typical columnar improvement methods, as the steel pipes can complement quality and strength to mitigate variations in strength due to soil type. ■ Short Construction Period Due to high surface friction and quality, it is possible to shorten the pile length compared to conventional columnar improvement methods, leading to a reduction in construction time. ■ Suitable for Narrow Sites Heavy machinery is selected based on site conditions to advance the project more efficiently.

For deep excavation work and cutting/removal of underground obstacles! Super Top Method.

For deep excavation work and cutting/removal of underground obstacles! Super Top Method.

The construction of place-driven piles in ground with boulders or bedrock, as well as deep excavation work, demonstrates its effectiveness in cutting and removing underground obstacles.

To safely carry out difficult all-casing deep drilling, maintaining high vertical accuracy while pushing in the casing and the reliability of the chuck device are key points. The RT series tubing equipment used in the Super Top method features a wedge-type chuck device and boasts one of the largest rotational torque and pull-out force in its class. Additionally, aiming for efficient and economical rock cutting, it is equipped with a casing pushing automatic control mechanism (B-CON mechanism) that can maintain the bit load at a constant value through "sequence control." The excellent workability and safety of the Super Top method with these features have been demonstrated through "technical review certification."

[Metal Road Construction Method Case Study] Nara Prefecture Road Improvement Project

[Metal Road Construction Method Case Study] Nara Prefecture Road Improvement Project

Ensuring safe and smooth passage! Case study of road improvement work on National Route 425, Jūzato to Sakon Nishikawa section (II-2 section).

National Route 425 in Nara Prefecture is a road that facilitates regional exchange, connecting the city of Gobō in Wakayama Prefecture and the village of Totsukawa in Yoshino District, Nara Prefecture. However, there are continuous sections with narrow widths and poor alignment, making it difficult for vehicles to pass each other in many areas. Therefore, construction was carried out with the aim of eliminating narrow width sections, ensuring safe and smooth passage, and contributing to tourism promotion. The site is located within the area of the World Heritage Kumano Kodo, and due to the need for consideration of the landscape and the preservation of water channels, the metal road construction method was adopted. 【Case Overview】 ■ Client: Nara Prefecture, Gojō Civil Engineering Office ■ Construction Period: January 5, 2022 – June 30, 2022 ■ Total Length: 19.0m ■ Width: 6.95m *For more details, please refer to the PDF document or feel free to contact us.

[Metal Road Construction Method Case Study] Yamanashi Prefecture Road Improvement Project

[Metal Road Construction Method Case Study] Yamanashi Prefecture Road Improvement Project

Design and construction that avoids interference with existing structures is possible! Here is a case study on the main local road Fujikawa-Minobu Line.

Here is an example from the emergency road maintenance and reconstruction project ordered by Yamanashi Prefecture. The Fujikawa Minobu Line (Prefectural Road No. 10) is an important route designated as a second emergency transport road. The site had a thick alluvial fan layer, and existing structures (stone walls and drainage) were in close proximity, creating a challenging environment. As a result, the design and construction that could avoid interference with existing structures while ensuring traffic on the existing road was evaluated positively, leading to the adoption of the metal road construction method. 【Case Overview】 ■ Client: Yamanashi Prefecture, Kōnan Construction Office (Minobu Branch) ■ Construction Period: March 24, 2021 – August 31, 2022 ■ Total Length: 42.5m ■ Width: 7.0m (8.2m) *For more details, please refer to the PDF document or feel free to contact us.

Ground Improvement Work "Stabilizer Mixer Method"

Ground Improvement Work "Stabilizer Mixer Method"

A ground improvement construction method that enables the construction of highly uniform improved ground!

The "Stabilization Mixer Method" is a construction technique that improves soft ground by mixing it with cement-based solidifying agents using a stabilization mixer, creating a uniform and highly accurate improved body. Due to high-speed stirring driven by a hydraulic motor, the workability is excellent, and cost reduction is possible as there is no need for equipment costs such as plants. Additionally, because powdered solidifying agents are used, the strength is greater than that of slurries with the same mixing ratio. 【Features】 ■ Construction is possible at depths of approximately 1m to 7m ■ Efficient construction is achievable ■ Low-cost ground improvement is possible ■ There is less variation in strength, allowing for the construction of high-quality improved bodies ■ Construction is possible with a variety of soil properties *For more details, please download the PDF or feel free to contact us.
