Easily construct pipelines in densely populated urban areas! A construction method that shortens the construction period.
The "Dual Shield Method" is a shield switching type of thrust construction method that incorporates the advantages of both thrust and shield methods. It employs a cost-effective thrust method for gentle curves and straight sections, while using the shield method for sharp curves and continuous curve sections. This makes it easier to construct pipelines in densely populated urban areas, significantly reducing costs. 【Features】 ■ Capable of sharp curves (R10m) without the need for rotating shafts at intersections ■ Can be constructed with shafts sized for thrust methods ■ Equipment from thrust methods can be used ■ Average daily progress increases by combining thrust methods ■ Using a mud slurry method increases thrust extension *For more details, please download the PDF or feel free to contact us.
