Underground piping seismic reinforcement method "WT method + TNF method"

Construction is possible on weak ground! A method that allows for low cost and short construction time.

The "WT Method + TNF Method" is a seismic reinforcement method for underground piping. It includes the "Underground Tank Rising Section and Base (WT Method)" which achieves a retaining effect through cement slurry improvement using a special mixer, measures against cutting due to tank foundation uplift, and piping reinforcement (seismic) effects achieved through "Underground Piping Surrounding Improvement (WT Method)." Additionally, the "Building Ground Improvement (TNF Method)" prevents differential settlement with powder improvement and eliminates the need for foundation formwork due to its soil formwork design, and the "External Ground Improvement (TNF Method)" provides liquefaction suppression effects through improvement. 【Features】 [WT Method] ○ Construction is possible on soft ground ○ No sheet piles or supports are required ○ Patent Number: No. 4039445 [TNF Method] ○ Construction is possible at low cost and in a short period ○ Patent Number: No. 3608568 For more details, please contact us or download the catalog.
