Catwalk cable erecting and hauling system for unnavigable waters and quick catwalk erecting method

Abstract

The invention discloses a catwalk cable erecting and hauling system for unnavigable waters. The catwalk cable erecting and hauling system is separately arranged on two main towers on the two sides ofa water, and comprises two first wire reeling devices arranged on the two sides of the water, a buoy device floating on a water surface, two guide devices and two second wire reeling devices. The twofirst wire reeling devices are arranged along a bridge axis and located between the two main towers, and steel wire ropes of the two first wire reeling devices are connected and form a reciprocating haulage cable. The buoy device is used for bearing the haulage cable and a catwalk cable, and the buoy device comprises a plurality of buoys distributed in the direction of the bridge axis at intervals. The guide devices are used for guidance of the catwalk cable, and are arranged beside the two first wire reeling devices. The two wire reeling devices are arranged on the tops of the two main towerscorrespondingly. The invention further discloses a quick catwalk cable erecting method. According to the catwalk cable erecting and hauling system, the catwalk cable is changed to be hauled from thehigh altitude to be hauled on a ground water, the needed hauled force is small, the hauled speed is high, the hauling difficulty is lowered, and the safety risk is lowered.

Description

technical field [0001] The invention relates to the construction field of catway cable erection, in particular to a catway cable erection traction system in unnavigable waters and a catway cable rapid erection method. Background technique [0002] In my country's highway traffic and other infrastructure construction, as the suspension bridge with the strongest spanning ability, it is always the preferred bridge shape for crossing rivers and seas. In the construction of suspension bridges, the catwalk is the most important aerial work platform and aerial walkway for the construction of the upper structure of the suspension bridge. During the construction of the upper part of the suspension bridge, the function of the catwalk is the construction site for the erection of the main cable and the hoisting of the stiffening beam. Cat road cables generally include load-bearing cables, handrail cables, door frame support cables. [0003] The construction of the catwalk erection is ...

AI Technical Summary

Problems solved by technology

[0004] (1) The traction system needs to bear the traction force and the gravity of the traction cable and the cat road cable itself, and the force is too large

[0005] (2) During the construction process, it is necessary to use large-scale machinery and equipment for operation, the construction cost is high, the operation is difficult, and the safety risk is high

[0006] (3) High-altitude traction operation, slow traction speed and low construction efficiency
