Method
Immersed Caisson Construction Technology
The submerged tunnel construction method is a technology to construct a tunnel, etc., at the bottom of the sea by immersing a submerged Caisson made of concrete, steel plate, etc., as a dry dock or on land.This method has the advantage of reducing the overall length of the tunnel because it is constructed by connecting artificial islands, etc., and can reduce the overburden of the tunnel.
