Constructing Method of Underwater Tunnel with Tethering Tunnel Modules and Underwater Tunnel Constructed by such Method

摘要

The present invention repeatedly performs the operation of sequentially coupling and installing new tunnel modules to the end of the pre-construction body part while moving the launching girder forward to construct the underwater tunnel, while the finish connected to the fixed cable Tethering the new tunnel module by watertight coupling and fixing the block to the side of the new tunnel module, but the tethering operation can be performed inside the new tunnel module. and guide chain-underwater tunnel construction method with tethering configuration using closing block”, and “underwater tunnel” constructed by this construction method.
