Ground reinforcement work | Streamlining the application process with the design-relaxable CWC method.

The Cross Wing Column Method streamlines the administrative procedures for ground reinforcement work. By relaxing design conditions based on GBRC performance certification, it prevents over-design and facilitates smooth applications.

In ground reinforcement work for construction plans, it is crucial to meet the standards of administrative agencies and inspection organizations, ensuring that confirmation applications are processed smoothly to prevent project delays. GeoTech Corporation's Cross-Wing Column Method (CWC Method) is a reliable deep mixing treatment method that has obtained the GBRC performance certification (No. 12-17 Rev. 1) from the Japan Building Disaster Prevention Association. With assured construction quality provided by patented six-blade mixing wings and proven data showing a coefficient of variation of 25% or less, some administrative agencies may apply preferential measures in design conditions, such as improved evaluation of allowable stress and relaxation of improvement length restrictions. This helps avoid unnecessary excessive design, achieving a reduction in the number of piles driven and cost optimization. The method accommodates sandy soil, clay, and loam layers, covering a wide range of specifications from diameters of φ400mm to φ1200mm and strengths of 400 to 1500 kN/m2. For small-scale buildings, the omission of mixing tests and simplified inspections are permitted, making the process extremely smooth. GeoTech strongly supports conformity assessments and structural design. Please feel free to consult us.
