Abstract

The invention discloses a construction method and a construction system for catwalk cable erection of a large-span suspension bridge. The method includes first temporarily fixing the first end of the cat road cable, then using a tugboat to transport the cat road cable, using a tower crane to hoist the cat road cable on the main tower, and after all the cat road cables are hoisted to the main tower, put the cat road cable on the second end. The two ends are sent to the shore and anchored on the anchor traction system on the shore, and then the first end of the cat road cable is sent to the shore and anchored on another anchor traction system. The construction system includes anchoring traction system, catway cable, catway cable saddle, tower crane and tugboat. The invention can quickly hang the catway cables on the catway cable saddles of each main tower, and use tugboats to transport the catway cables without a large hoist to transport the catway cables. The construction process is simple, the safety risk is low, and the construction time is shortened.

Description

technical field [0001] The invention relates to catwalk cable construction for a long-span suspension bridge, in particular to a construction method and a construction system for erecting a catwalk cable for a long-span suspension bridge. Background technique [0002] At present, in the construction process of catwalks of long-span suspension bridges in China, the usual practice is to first arrange fixed hoist traction systems on both bank slopes, and use the fixed hoist traction systems to erect catwalk cables. The traditional construction method takes a long time in the catwalk erection process. For engineering projects, the long-span suspension bridge is usually the controlling node project of the project. How to optimize the construction process of the catwalk and provide a reasonable and feasible construction period for the construction of other superstructures of the suspension bridge is a difficult problem faced by the construction of this part. Contents of the inve...
