Environmentally friendly and highly constructible tunnel repair method.
The "Tn-p method" is a tunnel repair technique that sends liquid I and liquid R to a mixing head via a pump from an injection machine, mixes them through air agitation, and forms polyurethane foam (Achilles Airon-R). Achilles Airon-R has a very fast reaction curing time of about 1 minute, which reduces the risk of material leakage from cracks and other sources. The injection equipment is compact, allowing all necessary materials to be loaded onto a single 4-ton truck. 【Features】 - The curing time is very fast at about 1 minute, reducing the risk of material leakage. - The injection equipment is compact, allowing materials to be loaded onto a single 4-ton truck. - It can cure even in areas where water is pooled, making it effective for groundwater sealing. - It is lightweight, resulting in minimal load on tunnel linings. - There is almost no expansion or contraction after injection filling, even with low-density foam, etc. *For more details, please download the PDF or contact us.
