- Site and ground investigation

Geological survey in mountainous areas using a portable penetration testing machine.
The portable penetration testing machine is a ground investigation device for mountainous areas that can perform standard penetration tests according to JIS A1219. By making the entire unit lightweight and minimizing its maximum length, it can be transported with a small crawler in most mountainous regions, significantly reducing costs for ground investigations such as those for transmission towers. This investigation machine and method obtained a patent on November 22, 2019, through a joint application with Tokyo Electric Power Company Holdings, Inc. and Celery Co., Ltd. (Patent No. 6619235). 【Features】 - No need for a boring machine, water supply equipment, or temporary work scaffolding - No need to lay monorails for transporting equipment - Material transportation is possible on slopes of up to 35 degrees with a small crawler - N-values are obtained every 50 cm through standard penetration tests - Almost continuous geological structure photographs are obtained through split images of the sampler for penetration testing - All equipment can be transported with a one-box car - The device does not rotate, allowing for the determination of the direction of geological structures such as slip surfaces.

Updated construction achievements (July feature "Bridges (Parapets)")
The July feature is "Bridges (Parapets)," and we have added three construction achievements. At Zaiens, we not only design, manufacture, and construct new wooden bridges but also conduct precise inspections and renovations of existing wooden bridges utilizing stock. Additionally, we address not only the entire bridge but also the bridge deck and parapets that people directly interact with. This time, we will introduce various case studies related to bridges and parapets, including new constructions and renovations.

Updated construction achievements (August feature "Wooden Fences and Panels")
The August feature is "Wooden Fences and Panel Fences," and we have added three new construction achievements. At Zaiens, we supply various types of wooden fences for different locations, including park boundary fences, fall prevention fences for waterways, fences for traditional Japanese facilities, panel fences, and fences in mountainous areas. Additionally, wooden panel fences can be used in urban areas as an alternative to concrete walls. Wooden fences and panel fences, which allow you to feel the warmth of wood, contribute to the promotion of wood utilization.

We completed the floor painting of a large logistics center.
We carried out floor painting work inside a certain logistics center located in Koto Ward, Tokyo. The floor area is approximately 1,600 square meters and since it is a floor that vehicles pass through, we used specialized paint for the job. For both new construction and renovation projects, please feel free to contact us for any inquiries regarding painting work.
