It excels in maintaining the stability of the face even in soil conditions where pressure retention at the face is difficult.
The "Super Flow Balance Semi-Shield Method" is a mud-based thrusting method that constructs a wall of high-density, high-viscosity fluid throughout the entire cutter chamber to facilitate excavation. In the tail void section, soil particles with good workability and high-concentration mud are directly pressurized from the outer circumference of the tunneling machine, reducing friction around the pipe. Furthermore, the two-component solidifying lubricant injected from the trailing pipe further stabilizes the void. 【Features】 ■ Excellent stability of the face ■ Can maintain a face management pressure of groundwater pressure + 20 kPa ■ Minimal range of ground loosening *For more details, please download the PDF or feel free to contact us.
