TN MethodSteel pipe inner excavation pile method and cement milk injection stirring method
About The TN Method
In the TN method, drilling is performed while removing soil from inside the pipe via an auger screw inserted inside of the steel pipe pile. After reaching the specified support layer, cement milk is filled via high-pressure injection and the foot protection is hardened. These foundation pile methods support structures through the formed expanded foot protections for the tips. The methods are widely used in the civil engineering and construction fields, and they can also be applied to steel pipe sheet pile foundations.
