INCREMENTAL LAUNCHING METHOD AND DEVICE FOR IMMERSED TUNNELS

摘要

PURPOSE: An incremental launching method and device for immersed tunnels are provided to obtain the simplicity and the economic benefit of the construction technique the extrusion process of the linked task of the underwater tunnel unit and underwater are made in the dry dock of an airborne. CONSTITUTION: An incremental launching method(1) for immersed tunnels is as follows: the step(10) for arranging the underwater tunnel unit the dry dock; the step(20) for extruding at an underwater through the door of the dry dock; the step(30) for connecting the behind freshly made underwater tunnel unit of the underwater tunnel unit extruded to an underwater is arranged; the step(40) for extruding the connected a plurality of underwater tunnel units with an underwater; and the step(50) for determining the underwater tunnel of the desired length was completed.
