Method special for transporting heavy prefabricated arch bridge assembled box girder

Abstract

The invention provides a method for transporting a heavy prefabricated arch bridge assembled box girder in a remote area. The method comprises the following steps of a, providing two heavy low-gravity-center transport vehicles; b, building two steel rails extending from a starting place to a destination in parallel; c, synchronously installing two transport vehicles on the two steel rails; d, installing a winch on the fixed base at the destination, and connecting a steel wire rope to the two transport vehicles; e, placing the prefabricated arch bridge assembled box girder on the two transportvehicles through a jack; and f, starting the winch, using the steel wire rope to pull the two transport vehicles to synchronously move on the two steel rails, and transporting the prefabricated arch bridge assembled box girder to the destination. By using the method, manufacturing cost is low, installation is easy, and a transportation tonnage is large. The method is suitable for construction in remote areas, little in environmental damage, high in practicability, obvious in economic benefit and the like. Detaching is easy after a component is used.

Description

technical field [0001] The invention belongs to the field of construction engineering, and relates to transporting heavy building components in remote areas, in particular to a method specially used for transporting assembled box girders of heavy prefabricated arch bridges. Background technique [0002] The Dabigou Bridge spans the Dabigou Gorge upstream of the dam site of the Kala Cascade Hydropower Station on the Yalong River, and is one of the important structures of the special traffic road project of the Kala and Yangfanggou Hydropower Stations. The bridge design bridge type is a prefabricated reinforced concrete catenary box arch bridge. The bridge site is about 370 kilometers away from Xichang City, of which more than 130 kilometers from Muli County to the construction site is a simple road between the original alpine forest farm. High mountains over 3,900 meters have extremely poor road conditions, especially in the winter rainy season. The external traffic is often...
