Constructing columnar ground improvement bodies! A ground improvement method that allows for the selection of construction machinery according to work conditions!
This is a mechanical mixing deep mixing method that constructs columnar ground improvement bodies by excavating and mixing the ground while discharging slurry of solidifying materials such as cement. By equipping the tip of the auger head with stationary wings and two pairs of mixing wings either above or below, it prevents the co-rotation phenomenon of the solidifying materials and the ground soil, allowing for the construction of improved bodies with stable quality. Due to its lightweight equipment mechanism, it can be selected from small to large construction machines, accommodating a wide range of site conditions. 【Features】 ■ Formation of stable columnar bodies in the ground ■ Elimination of the co-rotation phenomenon of mixed soil ■ Selection of models according to working conditions ■ Obtained "Building Technical Performance Certification" *For details, please request materials or view the PDF data from the download.

Company information
In the mid-1950s, during a period of construction boom leading up to the Tokyo Olympics, Asou Sangyo Co., Ltd. (now Asou Corporation) focused on the increasing demand for lightweight and labor-saving high-rise buildings. They recognized the advantages of using aerated concrete (air mortar), which excels in lightweight properties and thermal insulation, as insulation material, and established the company with the aim of manufacturing and constructing building-grade aerated concrete. The unique technology developed through research and development of imported technology from the United States, along with the excellent characteristics of their product (aerated concrete), matched the needs of the times. It was used for waterproofing on rooftops to reduce the weight of high-rise buildings, raising floor slabs on each floor, and embedding piping in mechanical rooms. Subsequently, the lightweight properties of aerated concrete attracted attention from various fields, leading to its adoption in numerous civil engineering projects, including the Tōkaidō Shinkansen construction. To date, the construction achievements have exceeded 10 million cubic meters, and the company continues to provide satisfaction to the times and society as a pioneer of air mortar and a technology development-oriented enterprise that responds to various needs.
