All-soil compatible small-diameter mud-water / earth pressure thrusting method "Cobra Method"

A leading conductor with a wide range of soil adaptability and high torque performance! Construction in a small shaft for a wide variety of ground conditions!

The "Cobra Method" is a revolutionary small-diameter thrusting method that can be used to construct from ordinary soil to boulders and bedrock using a small shaft. The unique joint pipes within the Cobra thrusting pipe prevent rolling and respond to unexpected ground conditions that could pull the tunneling machine out, allowing for high-precision construction. Furthermore, even in challenging ground conditions, it is possible to achieve thrusting distances of approximately 200 meters. Additionally, all components, including a compact mud-water treatment system that can be mounted on vehicles and a disassemblable main body, are designed to be small and space-saving, allowing for retrieval from manholes. 【Features】 ■ High torque performance with a wide range of soil adaptability ■ Realization of smaller shafts ■ Improved convenience for retrieval with a four-part tunneling machine ■ Capable of thrusting approximately 200 meters in harsh ground conditions (with applicable conditions) ■ Ability to select excavation methods according to soil type *For more details, please feel free to contact us.
