LONG-DISTANCE PROPULSION METHOD FOR PREVENTING THE DEFLECTION OF THE HEAD OF A PROPULSION PIPE APPLIED FOR ENGINEERING WORKS, ROAD, RAILWAY, APARTMENT, WATER RESOURCES, STRUCTURE, HARBOR, AND WATER SUPPLY FIELDS

摘要

PURPOSE: A long-distance propulsion method for preventing the deflection of the head of a propulsion pipe applied for engineering works, road, railway, apartment, water resources, structure, harbor, and water supply fields is provided to prevent the deflection of the head of a propulsion pipe using a structure for supporting the weight of a cutter head machine.;CONSTITUTION: A long-distance propulsion method for preventing the deflection of the head of a propulsion pipe applied for engineering works, road, railway, apartment, water resources, structure, harbor, and water supply fields is as follows. Multiple through holes(200) for reinforcement are formed along the longitudinal direction of a propulsion pipe(101) in a line. When the through holes are sealed, the propulsion pipe is inserted into the ground. A cutter head machine(100) is located at the front end of the propulsion pipe, and the through holes are opened. An excavation work is performed. A support block is inserted into the propulsion pipe through the through holes. Mortar layers are formed by spreading mortar on the through holes and are cured.;COPYRIGHT KIPO 2012
