Construction near sharp curves and buildings is possible! It can be carried out even on soft ground and aquifers.

The "Open Shield Method" is a construction method that serves as an alternative to traditional open-cut and shield methods, used for burying structures such as conduits underground. It allows for construction on sharp curves and close to buildings, with minimal noise and vibration. Additionally, it can be implemented in soft ground and aquifers, and the upper part of the shield can be opened. 【Features】 ■ A construction method that replaces traditional open-cut and shield methods ■ A method for burying structures such as conduits underground ■ Capable of sharp curve construction and close proximity to buildings, with low noise and vibration ■ Small construction width results in less construction waste, considering the environment *For more details, please refer to the PDF materials or feel free to contact us.
