摘要

PURPOSE: An incremental launching method and device for an immersed tunnel by a hydraulic jack are provided to support the rear end of an immersed tunnel unit with the hydraulic jack and to process the pressing operation.;CONSTITUTION: An immersed tunnel unit is arranged within a dry dock of land(10). The immersed tunnel unit is extruded through a vertical jack extruding device to the bottom of the sea(20). Another immersed tunnel unit is connected behind the extruded immersed tunnel unit. The vertical jack extruding device performs a repetition extrusion process(30). The hydraulic jack is established in a tip of the immersed tunnel unit and makes the balance of the leading end water pressure(40). The immersed tunnel unit is additionally extruded by the vertical jack extruding device(50).;COPYRIGHT KIPO 2010
