Subsurface Obstacle Adaptation Type Slurry Shield Method 'Milling Mall Method' Performance by Obstacle Type
A propulsion method equipped with four special functions: exploration, improvement, cutting, and guidance! Presentation of construction achievement collection!
The underground obstacle-responsive mud-based thrusting method "Milling Mall Method" consists of three devices: a tunneling machine, a special expandable pipe, and a special injection pipe, which pulverizes and discharges metal obstacles. It explores metal obstacles ahead of the thrusting excavation while pushing them forward, and it is also possible to improve the ground from inside the tunneling machine before and after the obstacles. Furthermore, a receiving coil is installed at a designated position inside the arrival shaft, and a system is equipped to guide the tunneling machine to that position, making it the ultimate thrusting method that provides peace of mind even when obstacles are encountered. 【Performance by Obstacle Type】 ■CASE-1 Cutting of Hume pipes ■CASE-2 Cutting of PC beams ■CASE-3 Cutting of H steel and reinforced concrete ■CASE-4 Cutting of H steel existing manhole walls ■CASE-5 Cutting of wire tetra pods *For more details, please refer to the PDF materials or feel free to contact us.
