Open shield method
A construction method that utilizes the advantages of both the open-cut method and the shield method!
The open shield method is a new open shield technique that has been improved to adapt the advantages of both the cut-and-cover method and the shield method for urban areas, agricultural drainage channels, and soft ground. It is the most suitable method for constructing underground structures such as box culverts in locations where excavation is possible but soil retention using sheet piles or similar methods is difficult.
