Shield Launch and Arrival Method 'NOMST'

Shortening of construction period is possible! Automation and labor-saving for departure and arrival can be achieved, resolving the difficulty in securing craftsmen such as those for demolition work.

"NOMST" is a new shield launch and arrival method using new material concrete. In conventional methods, ground improvement was necessary as protective work for the launch and arrival of the shield, and manual demolition of the pit wall at the entrance was required. However, with NOMST, new material concrete that can be cut by the cutter bit of the shield machine is used. Ground improvement through chemical injection is unnecessary or can be reduced, allowing the shield machine to launch and arrive without the dangerous manual demolition of the entrance. 【Features】 - Ground improvement for launch and arrival is unnecessary or can be reduced, enabling groundwater pollution prevention, shortening of construction periods, and cost benefits. - Safety during launch and arrival is ensured. - Dangerous work is eliminated, making safety management for workers and supervisors easier. - Construction periods can be shortened. - Automation and labor-saving for launch and arrival can resolve difficulties in securing skilled workers such as those in demolition work. *For more details, please refer to the PDF document or feel free to contact us.
